Acer :: 6920g Thermal Pad Or Thermal Paste For The Northbridge
Jul 16, 2009
i have a question for everyone who has removed the heatspreader from an acer 6920g. Did the northbridge made contact with the heatspreader by a thermal pad or by a thermal paste ? mine had something that looked like a thermal pad but when i tried to remove it , it tore into small pieces ( i know a thermal pad is not like that ). i used a thermal paste when i put everything back together. Should i open it up again and use a thermal pad for the northbridge ?. In everst in the sensor menu it shows 42 degrees celsius for the motherboard sensor ( i assume that is the northbridge).
My notebook, Acer 5755G is after warranty and it's overheating. I have to clean a cooling system and change thermal paste. On the Internet I found few guides, but there people are dissembling this notebook almost completely... Do I have to do it or can I just remove a back cover to get access to cooling system?
I just had the motherboard/video card on my m1530 replaced by the dell guy because of the old defective graphics card issue. I watched him do the whole thing, and when he re-attached cooling mechanism to the motherboard, he used new thermal paste for the cpu, but not the video card.
I asked him about this, and he said that the surface of the gpu is different and doesn't need it. I don't really believe this, since it looks just like the desktop gpus that I always use thermal paste on. I'm getting pretty high temps now (65-70C idle).
Alright, my CPU is idling at 75c and my GPU is at 80c, I've opened up my M170 and It didnt seem dusty at all, so I went out and bought a small tube of AC5 which people say will help.
Now the problem Is I have no idea where to apply it, or how much is needed. I dont really know anything about hardware components, so If anyone has any pics which could show me where and how much to apply that would great.
The M170 is currently in peices at my desk and Im typing this on a MacBook, and I really dont want to spend anymore time on the OSX than I have to.
Well i finally decided that i should give this a try after seeing my temps creep up by about 1 degreeC per week. I just ordered some Arctic Silver 5. Ive looked at all the thermal paste topics here and still have a few questions. Firstly, what exactly is the thermal pad and do i have to worry about it? I saw that some people had to remove the pad but when i read through
http://www.robertbromfield.com/Tutor...he%20M1530.pdf tutorial i didnt see anything about taking off or replacing a thermal pad. Secondly, when applying the thermal paste, do i want to cover the whole "black square" of the cpu/gpu with a thin layer?
And lastly, i heard that this may void your warranty. I was wondering, if i did break my lappy somehow, couldnt i just clean it off so that when the tech guy comes i just claim that i never even opened it up?
I already undervolted my computer which did help, but the fan is so weak now that I feel i need to do everything possible to keep it from overheating. Does anybody have an extensive guide on applying thermal paste?
I really need to do this. I am pretty noob at computer hardware, So i would need a guide that would even tell me how to take apart my entire case/etc... I am sorta running out of options.
My temps are starting to creep up and I suspect the thermal paste is the culprit. I'm looking to replace it. If anyone has done it before. My question is, does the Vostro use a thermal pad or just a heatsink on on top of the CPU?
I checked the service manual and it made no mention of a thermal pad. Just looking to make sure before I tear it down.
I was thinking of changing my thermal paste on my CPU and GPU chipset, many ppl out there saying this would void the warranty and hell yeah it will, but the question is, will DELL engineer would be able to differentiate between stock silicone paste and new thermal paste (for my case is Coolermaster Nanofusion), anyone ever get busted by modding XPS?
Unless you change the obvious purple/pink thermal pad at the ACPI chipset to copper sheet then it's a totally different story.
So ive been dabbling with the thermal paste on my m1530 for a few months now but havent really stressed the gpu to know for sure. Today however, while playing l4d, my gpu temp got up to 88 degrees C and my cpu was in the high 70s.
I havent seen these kinds of temps since i got my mobo/heatsink replaced a year ago. I have opened up my laptop and my fan looks a little dusty but i am not sure if that would warrant a 88 degree gpu temp.
I am wondering if this could be because i applied the paste incorrectly? I am quite sure i did it right and i followed the instructions that were posted on here for m1530s exactly.
I replaced the thermal paste of the CPU and the GPU with "Coollaboratory liquid pro". And I replaced the thermal pad of the northbridge with "Arctic Silver 5" thermal paste.
Here are my sesults (in a 20 degrees Clesius enviroment, T9600, 2,8GHz, stock voltage): 73 dregrees Celsius at 100% load (instead of 92) 39 dregrees Celsius at 0% load (fan off) (instead of 45)
According to my research and different experiments this combination is my actual optimum. The cooler and more silent system supports my usage of voice recognition (using the internal mic). Of cause later the voltage could be reduced using rmclock.....
Due to popular demand of people requesting a guide on how to change their thermal paste I decided to make a video guide for the community as a way of giving back. Enjoy and sorry if I'm no high quality youtube blogger. This is my first video ever.

You need isopropyl alcohol(99% or high purity)/arctic clean solution would work too with Q-Tips to clean up the previous compound. So please have that handy guys.
Also watch this video on why I will not spread the compound but put a pea size dab of the compound and let the pressure spread it. You do not want air pockets between your cpu and heatsink, it will cause a lose of the thermal interface and wont work optimal. http://www.youtube.com/watch?v=EyXLu1Ms-q4 .....
The LCD on my 700m quit working after I dropped it. But OK on external monitor. Got new screen on eBay. Part # slightly different but that's moot now.
After hooking up the two cables to new screen and putting battery back in, I pressed START button. The light would come on for a few seconds and then blink off, accompanied by a faint click. The data cable to screen got very hot in just a few attempts to start up.
Now nothing works (no more blinks and clicks) with either LCD, on either battery or mains. At this point I would be happy just with external monitor. Had I tripped an thermal overload device, and is there a reset button?
what i wanted wass to fix/bypass the sensor without having to replace the damn board. i couldn't even find a single post staing where exactly the sensor is on the board. my problem specifically was that beer got spilled on the keyboard. after a while the machine shorted and shut off. I have a Dell Inspiron 9300, with a 1.73 ghz Sonoma CPU. i left the laptop off for two days so some of the liquid would dry out. after some problems and a dozen reboots i got into the bios, then finally through to windows. everything was fine except that the CPU was working at a very low frequency. also the fans were continually at highest speed. the CPU was being reported between 101 mhz to 503 mhz, depending on the software. it was being recognized correctly but showing to operate at 202 mhz in the system properties panel. what was really striking is that the notebook harware software i had installed was reporting the CPU temperature as 85 C. I tried various software to manipulate the CPU frequency to no avail. The temp was a constant 85 C, although i could tell that it was not even close to this temperature since i my laptop was partly disassembled and i could feel the surface of the heatsink with my hand; it was cool.
I finally surmised that the problem was with the thermal sensor on the motherboard. it had probably shorted or got soaked and was reporting the highest temperature it could as a safety measure, thereby limiting the CPU to a very low frequency and not allowing it to throttle above 503 mhz.
My last option, save for replacing the motherboard, was to find the sensor chip, clean it, dry it and hope that it would work again.
But this is not what solved the problem. somewhere on the net i came accross a code, that when entered on an Inspiron 9100 (an older laptop, with a different chipset) would bring up the Thermal Management screen or something like that, which is certainly not accessible via the BIOS. I was playing around with the settings on a program called Hardware sensors monitor, again to no avail, when i finally decided to enter this code:
FN key + zxcvasdqwer. almost the second i pressed z, or maybe after x, the high speed fans shut off! after a short while they kicked back into operation but at a low speed, just like they were supposed to. the program hmonitor began reporting a more realistic CPU temp. i tried to play a high-def movie file and finally it played normal, without any lag or stuttering! as i played it, the fans kicked into higher mode, and the temp which had been steadily rising, began to drop. the program, and most other programs were still reporting the cpu at 202 mhz, windows system properties as well. but since it was playing a 720p video file normally, it had to be much higher than that. i did a reboot and voila!
all monitoring software are now reporting the CPU at 1.73 ghz. the system temperatures are perfectly normal, and at idle the CPU goes as low as 20 degrees C. The software Speedfan, however, is still giving an error regarding the sensor chip on the motherboard.
I seemed to have fixed the severe thermal sensor problem by a few keystrokes, without having to replace the motherboard or even the sensorchip. in fact, i didn't even have to find the sensor node and clean it.
I came accross more than a dozen people who had a very similar problem to mine, with the temperature being reported at 85-86 C, for no reason. At least those who have a Dell notebok might be able to solve this problem.
I have been reading a bunch of threads on decreasing temps and I am now thinking about changing the thermal compound that the machine shipped with.
I had originally seen a lot of people recommending Arctic Silver but I was not sure which one so I started to llok for more info and am now thoroughly confused. From what I have read some are designed for a more permanent mounting which I do not want since I may want to change the CPU in the future.
Also it seems some work better than others in certain applications which I don't understand. To me all it is doing is transferring heat so what it is transferring heat from shouldn't matter. But since it does seem to have some effect what has worked well for other SXPS 16 users.
My new SXPS 1645 arrives Monday and I have AS5 and cleaner handy.
I need to know where to apply AS5 and what to do about the motherboard chipset and GPU RAM. There are these thick sticky pads on those, do I peal them off and use AS5? Can I leave them on or do I need to replace them?
