Dell :: Vostro 1310 Fan Noise
I recently purcahsed a vostro 1310 laptop. It's been absolutely great, except for one thing: the fan is incredibly annoying.

Once the processor reaches 45 degrees celsius, the fan kicks in, lowers it to 40, and then turns off. A few minutes later, the computer will go up to 45, and the fan will kick in again; so it goes through this loop of turning on and off, which is incredibly annoying.

Doing some more research, I've found that other people have also had this 'problem'. Undervolting and switching to powersaving mode solved the problem a bit, but once it hits 45, I still have the same problem.

Dell :: Vostro 3700 Weight And Proc
I know there are a couple of 3x00 Vostro threads, but some are very long and the other did not seem to have an answer for this question.

First, I am very interested in this new Vostro. It seems a good configuration and design for the price. I especially love the 17" screen at < 6 lbs. Seems too good to be true.

Does anyone have experience with this machine? Is the weight including the battery and everything? It is a pound lighter than the 16" Sony F I am using. I like the F, but this Vostro seems a little more in line for me (PhD, heavy stats and datasets). My wife woul appropriate the Sony if I were to pull the trigger on the Dell.

Also, the i5-520m to i7-???qm (dual to quad, differing clocks and all). I am thinking the i5 may be the way to go. Most of my stuff is not designed for 4-cores, 8 threads, etc.

Dell :: Inspiron 15 Or Vostro 3500?
I am looking for a little expert advice on a Dell 15" and wonder what are the main differences between the Inspiron, Studio & Vostro models? I will be using it to display photos and websites and will not use it for gaming. The display and overall looks are probably the most important. . BB has a Inspiron 15 with a i3 processor for $649.

I am also looking at the Lenovo 15" models because I think I have narrowed my choices down to these 2 manufactures.

Dell :: Screen Resolution On New Vostro 3400 And 3500?
There is no configurable screen and the tech specs don't say other than "HD" which most people use for 1366x768.

Has anyone been able to confirm the screen resolution on the new Vostro 2500 series or 3400?

Any idea on how long it takes them to make it a bit more configurable?

Dell :: M6400 Fan Noise
I find the noise of the fans of my M6400 quite disturbing.

It is certainly much louder than the noise from my M6300 (also a 17" high performance laptop), or my former D810

The fans kick in quite often after short periods of being off.

Is there a way to slow down the fans or have them off for longer?

Is there a compatible fan in the market that is quieter?

Dell :: Fan Noise On Studio 15
I just got a Dell Studio 15 from the Dell outlet and while it's a great laptop I am wondering about the fan. It runs constantly and you can definitely hear it the whole time.

When I opened the media player it revved up a little but I wasn't even playing a video. Is this fan noise and constantly running fan normal for the Dell Studio 15?

I love the laptop but I think it is louder than usual and find it odd that the fan runs all the time. The bios installed is A05.

I have the model with an ATI video card if that makes any difference.

Sony :: Z: Fan Noise
I just picked this baby up on Saturday and I'm about to return it as it has to be flawed.

2.8Ghz with the bluray drive. I've upgraded it from Vista64 to Win7 RTM.

Even at "silent mode" the fan is louder than my 17" MacBook Pro or my 15" Thinkpad W500.

That seems...wrong. It's blowing hot air out even when the machine is just sitting there doing absolutly nothing. It's sitting next to me on my desk next to the W500 (which is dead silent running discrete graphics). It's in STAMINA mode, running in SILENT, and still loud.

This will be a fun return as I am going to fight the 15% as the sales guy told me it was a quiet machine.

Sony :: SZ Fan Noise
This seems to be a common problem with Vaio notebooks, especially the SZ series.

I've had an SZ460 for a couple of years, and I'm starting to have problems with the fan. It's not the loud buzzing noise you hear when the processor is overworked. It's more like a rattling noise. I took the fan/heatsink out completely and cleaned it with a can of air, but the problem still persists. I have a feeling the bearings are shot.

The only replacement fans I could find are on eBay for $30-40, and they appear used. Where can I find an OEM fan for this notebook?

Dell :: M1530 Fan Noise Unusual
Whenever I am using my M1530 for simple tasks, such as surfing the web or checking my email, my fan is always running. It isn't running loud but it is audible 20 or so feet away. Hardware monitor places the CPU temperature at 45C and the GPU at 62C. According to task manager my CPU useage is right around 10%. Is this normal?

Dell :: Downgrading E6500 For Less Fan Noise
The fan starts after a few minutes when the machine has booted. The fan will start even if I only run simple HTML-webpages etc. Afterwards it never stops but keeps running relatively fast (and noisy).

My current config is:

* P8600(2.40,1066MHz,3MB)
* NVIDIA Quadro NVS 160M
* 250GB serial ATA HDD 7200RPM (Free Fall Sensor) (Seagate ST9250421ASG)
* Intel WiFi Link 5300 (802.11 a/b/g/n 3X3) 1/2 MiniCard
* Dell Wireless 370 Bluetooth
* Primary 6-cell 54W/HR LI-ION
* 15.4in Wide Screen WXGA+ (1440x900) with LED backlit
* Windows Vista Ultimate to XP Pro SP3 Downgrade SP1 with XP SP3
(Running XP currently on the machine)

Since I don't play games much and generally don't run 3D-software it was maybe a mistake to buy the E6500 with the dedicated NVIDIA-card, but I figured it was a nice feature to have in the future if I needed it.

I've tried various software to reduce the fan noise without much luck. Currently I'm considering returning the E6500 for a downgraded version without the NVIDIA-card, a lower clocked CPU and a slower HDD.

I'm considering:

* P8400(2.26,1066MHz,3MB)
* 250GB serial ATA HDD 5400RPM
* Mobile Intel® Graphics Media Accelerator X4500HD

1) Does anyone for sure know if the fan will run slower or maybe not at all if the E6500 is equiped with the Intel X4500HD instead of the Quadro NVS 160M when I surf webpages etc. and don't run GPU-intense software?

2) Will the fan run slower with a 2.26 GHz P8400 instead of a 2.40 GHz P8600?

3) Will a 5200 RPM HDD generally generate less heat in the system vs. a 7200 RPM HDD? (and hence generate less fan noise?)

4) I would really like to know how the BIOS determines how fast the fan should run? Is it dertermined from the overall system-temperature? The CPU-temp? or the GPU-temp? HDD-temp? Maybe an average of these?

Right now the fan has run relatively fast (docked) for about an hour. According to PC Wizard 2008 the temperatures are:

- ACPI Thermal Zone: 31.5 Celcius
- Core 1: 25 C
- Core 2: 26 C
- GPU: 49 C
- HDD: 38 C
- Processor(s) activity: 1-3%

I have the fan-noise issue whenever the machine is docked or not. I like the E-port Plus very much, a digital S/PDIF-audio out would have been nice though. I hope I can use the E-port Plus with the integrated Intel X4500HD if I decide to downgrade. Dual-view is a must for me.

5) I'm not sure if DELL at all will exchange my E6500 for a downgraded version. Does anyone have experience returning DELLs when asking for a downgrade? My argument is to much noise from the fan to my taste, but I don't think DELL will buy this if there's no problem with the machine, so I probably will have to pay for the return of the first machine as well as freight for the new machine. It's quite expensive here in Denmark. Returns cost about $125 and Dell will pick up the machine, the only way to return here afaik. I have 3 year International Next Business Day On-site Response, but probably of not much use if the machine isn't broken or don't need repair.

I nice side-effect from downgrading to a slower system though, will be longer battery-life, but my ultimate goal is less noise.

Dell :: Old Inspiron 9100 Fan Noise?
My dad's laptop that he got about 5 years ago is a great desktop replacement. It's never caused any problems.

But my question is about the fan, it's really loud! And it's always on continuously. Is that normal? It's been like that since he got it. I've never heard a laptop so loud.

I blow into the fans regularly but is there something else I can do to get rid of the noise, or is it normal?

Dell :: Inspiron 9300 Fan Noise
Both the fans of my Inspiron 9300 make a lot of noise. Previously in order to reduce noise I tried to completely remove the fans and cleaned them with compressed air.

At that time I found it weird that they did not make much noise when they rotated (pretty fast) because of the compressed air. The fans keep making the same amount of noise.

I notice that if I apply some pressue next to the keyboard where the fans are located the noise emitted changes.

Acer :: Fan Noise On AA1s
Is it common to hear a little bit of fan noise on these netbooks? It doesn't sound bad, but you can hear a faint "buzzing" of a tiny fan motor in a quiet room.

Sony :: Fan Noise On (NW270F)
I've had this laptop since early December and have noticed a noise coming from the fan. It sounds like a faint siren sound or whirring. I know that's probably an odd description but that's what it reminds me of. It's not terribly loud but just loud enough to be distracting sometimes.

This only happens when I'm not running a lot of stuff (just using Word for example) but when the fan cycles up that noise goes away. Unfortunately, I'm just using Word about 90% of the time so I hear this noise. It will make the noise for a second, then go away for a few seconds, then return.

I called Sony just to ask if there was some kind of setting (I don't know) that could be changed. They said it sounds like the fan needs to be replaced, and set up a home service call. The guy came, changed the fan and...same noise.

I've found a few references to odd-sounding fans on Sony laptops. But I'm wondering if anyone can confirm that this noise is normal and I'll just have to put up with it?

Sony :: Vaio Z: How Are We With The Fan Noise Now

HP/Compaq :: HP DM1 Fan Noise
I just bought a DM1 and noticed that the fan is always on, even when i run on battery and is doing nothing but idle on the desktop. The fan is pretty high pitch and therefore pretty audible.

I just read on other posts that Speedstep is actually a bluff on the SU2300, it doesn't trottle clock, thats probably why the fan is on even when idling on battery.

Sony :: Vaio FW Noise / Fan Control
I've recently purchased Sony Vaio FW21E (European model) and to my surprise, I find it quite noisy (contrary to what you can read in many reviews).

The first problem is HDD - I've owned 3 notebooks so far and no one had such a noisy disk. I almost thought that there is some kind of motherboard or GPU fan in there until I opened the case to confirm that the noise really comes from the HDD. It is quite unpleasant in a totally quiet room (like in the night) but I can hear it even during evenings when the room is relatively quiet. Vaio owners with Toshiba MK3252GSX disk (320GB), do you experience the same amount of noise? (On the upside, the performance is really nice compared to my older laptops, Windows Experience Index being 5.4.)

The second problem is the main fan (which I understand is the only fan on this Vaio). It is quiet for the first hour of usage or so but then it always turns on for about 5 minutes, then it's quiet for another 2-3 minutes, then it goes off again etc. etc. I really find this annoying because the fan speed is changing frequently and rapidly (i.e. from zero to high spinning, then it slowly goes down to what I would call acceptable level, then it stops rotating immediately; then it goes of for 100% again etc.)

When you combine these 2 noises, the notebook is quite unpleasant to use in quiet conditions. From the right hand side where the disk is placed, you constantly hear a whisper-like sound while from the left side, you are distracted by the main fan which tends to be turned on and off in a few minutes intervals..........

Dell :: Studio 1749 Fan Noise/temperature Problems
I've recently received my dell studio 1749 laptop with the following specs,

- i5 CPU 520m

- 4 gigs of RAM

- Intel HD graphics

- 320 gig HD

The problem with this laptop is that the fan will start to whine every few minutes seemly without reason.

I've done some investigation and found out the following:

- there seems be a threshold of 35 to 36 degrees celsius. Once the CPU hits that temperature, the fan will start to cool it down to under 30 degrees

- the idle temperature of the CPU is always creeping up, even without load. If I leave the computer alone at idle with almost no CPU activity, the temperature will creep up to the threshold...thus triggering fan.

the cycle repeats itself every few minutes.

I've attached a picture to illustrate the problem.

Since this is my first laptop, I want to ask does the CPU temperature stay constant during idle? or does it creep up like mine?

Can the threshold be modified?

Is this normal with the dell studio?

I thought this would not be such a big deal when I bought it, but I was wrong. i8kfangui does not work, I turn power to 'power saver", but even then fans go full speed.

Dell :: Latitude E6400/E6500 Owners Fan Noise?
I'd like to ask any E6400 or E6500 owners about their fan noise as I'm considering those machines right now. I'm thinking of going with the Intel 4500 graphics for hopefully less heat and noise than the Nvidia NV160.

How long does the fan stay off while doing basic web browsing? When it turns on does it ramp up to a slow speed or does it blast on and then ramp down to a slow speed? Does this cycle of off and on continue?

The reason I'm asking is I had a Lenovo Ideapad Y430 that was very irritating regarding fan noise. With basic web browsing or even idling the machine the fan would stay off for about a minute or two and then would blast on when it turned on before ramping down immediately to a slow speed for about a minute. Then it would shut off and this cycle would continue over and over. Was very distracting and annoying when in a quiet environment.

I'd like a fan with either consistent fan noise (stays on at slow speed forever) or with no noise at all (stays off forever). How close is the E6400 or the E6500 to this ideal behavior?

I was amazed when I tried out a Dell Studio 1537 that had a fan that didn't turn on at all while web browsing. I could use it for hours and it wouldn't turn on.

Sony :: Vaio VGN-SZ48GN Fan Noise
I have just downgraded my T7200 CPU to an T2300 so that the CPU temperature could go down. And that it did. from 68 degrees to 45 degrees in idle but stil the fan is going at it at full speed even at 45 degrees.

I found a post on this forum were a person says that the BIOS has to flashed whit an modede version of the bios file. But how do I make a moded bios?

Its from this topic that I found out that the BIOS has to be changed so that the fan only runs when it needs to and not when it works under normal idle CPU loads:
SZ fan noise?

Sony :: Vaio VGN-SZ770N: Fan Noise
Ive had this laptop for 3 months and Im quite dissapointed about the fan noise - it is running constantly. My experience is that the fan is running in 3 modes: minimum (always), medium (short time) and max (when using graphics ex.). Sony Support told me that it is normal that the CPU fan is running when the computer is swithed on (=CPU on).

My experience with laptops though is that they are quiet all the time, but eventually starts the fan when using many applications (graphics ex.). The symptom is the same in Windows XP, Linux and FreeBSD. Is it normal behaviour - I mean, should it run constantly or occasionally?

HP/Compaq :: Arelaptop Fan Noise Problems Prevalent
With Windows 7 about to drop, and HP rolling out with their new laptops (like the dm3t and Probook 5310m), I'm seriously looking at getting a HP to replace my old computer.

How prevalent is this, especially in the dm3 (for those already with one), and the Probook line (I'm looking at getting the 5310m)?

HP/Compaq :: Presario C500 Fan Noise And Grind
i have a presario c552us laptop and it recently started making weird noises around the fan underneath. i took a look and it seems to be coming from the fan. it sounds like some1 stuck something in there and its hitting the fan blades. doesn't happen all the time either. when the fan is spinning, sometimes its great(like right now) and other times it sounds horrible.

i took apart the whole laptop and cleaned out all the dust, especially in the heatsinks and fan assembly. it seems to spin fine when i use canned air on the fan blades. it has the normal high pitch fan spin without the grinding noise and what not.

not sure what the deal with that is, but maybe the fan has issues gripping or spinning itself.

so it sounds like i pretty much need to replace the fan and the motor.

can i replace just the motor and fan? or do i have to buy the whole assembly with the weird shaped heatsink?

HP/Compaq :: HP DV5 Excessive Fan Noise On Startup
For the past few weeks my DV5 has been behaving oddly when booted up from a cold start. The fan switches on producing an incredibly annoying rattle and squeal that almost sounds as if a bearing has gone in it. It's the same noise you occasionally hear from desktop fans that are clogged with dust and gunk.

It usually lasts for only a few seconds on initial bootup and is all over by the time Vista loads.

However, this laptop spends 95% of its time on my desk in my dorm room, residing on an improvised laptop stand for better cooling. I took it into the shop I bought it from now that I'm home and whilst they were happy to look at it, it just wouldn't replicate what I had been describing to them when they were listening to it. Murphy's law I guess. Anyway, they thought the only way to sort it out would be to leave it with them and they would try it daily till it it reared its head. Not knowing how long it would take to get over its stage fright (and needing some information off it) I declined that offer!

Has anyone noticed similar traits or symptoms in their machines? If so, how did you remedy it? I'm really tempted to pull it apart myself but it is only 7 months old so well within the warranty period that I may put in jeopardy.

HP/Compaq :: HDX16 Fan-noise And It Sounds More Like A Grinding Sound
I have had my HP HDX16 for almost a year, probably 10 months. I can still send it in for repairs because the warranty is still in place.

Recently the fan has started to make some funny noise and it sounds more like a grinding sound that is subtle but still noticable. I was thinking of sending it in for repair, but when I sent my computer in last time they formatted everything just to replace the screen when I told them not to, so I really would just see if I can repair the issue myself and save myself the trouble of having to reinstall and download everything again.

How easy will it be to take off the bottom to get to the fan? I already blew air into and that made it go from loud to subtle, but it seems like it might be grinding against something or hitting something. Sometime if I tap on the area to the top left of the power button it will stop it for a couple of minutes.

Apple :: MacBook -enabled Features That Would Interfere With Privacy - Fan Noise - BIOS- Drivers
For quite a while my GF has nagged me for a "nice laptop", i.e. a MacBook. With the new models out, the old ones (just before the latest one-piece-thingies) should be easier to find. Most of her friends have one and I am soon getting my bonus, so starting to shop around.

Myself, I am a ThinkPad evangelist (those "ugly, square, black things" according to my GF), and have no trouble picking a used one. With Macs I am basically into uncharted territory, hense my post.

1) I am concerned if the previous owner has enabled features that would interfere with our privacy - remote activation of camera, remote access, etc. How can I check this and make sure she will not participate in some amateur BigBrother?

2) What should I check on a 13 inch MacBook except the obvious battery, fan noise, scratches and dirt beyond normal?

3) Does the Mac have BIOS, drivers, etc. I should upgrade before I hand it to her?

Therefore the Studio Slim/Vostro 220 seem like the best small dell computer that I can use as a media center PC (streaming movies, pictures, live TV all from WMC/tv tuner). Does anyone know how is the noise level is? Can it be heard? Watching movies? Fan noise?

The noise of the system is a deal breaker/deal maker for me so the more detail anyone can give the better

Dell :: Precision M4400: "Again" Fan Noise
Why ist it, that the CPU fan runs with 3000 rpm, when the CPU is idle and the temperature of the CPU is 37 degrees? Also the chipset temperature is not that high. I made you a screenshot:

I tried everything to get the fan start much later. I used Artic MX-2 thermal compound, liftet my M4400 higher, undervolted it, but nothing works.

In my point of view, DELL made something wrong by programming the BIOS. Is it unnecessarily to run a CPU fan at 3000 rpm when the cpu is cool enough.
Maybe 800-1000 rpm would be fine.

So my question is:

Is it possible to use a kind of speed controller, know from desktop system, to making the fan run much slower?

As far as I see, Dell uses a 4-lines PWM connection the the mainboard.
