Dell :: Studio 15 Fan Running At Maximum RPM "randomly"

for those who own the Studio 15 and have been unlucky enough to experience the spontaneous loud fan that occasionally turns on. By "occasionally" I mean almost all the time and by "loud" I mean full blast for hours on end. This problem may persist whether the machine is running the A02, 03, or 05 BIOS and can be extremely frustrating, especially in a quiet environment such as a library or lecture hall. It doesn't appear to be a software issue or a BIOS issue since the problem persists with any version. It is in now way related to dust or high temperatures.

I recently noticed that applying pressure in the area of interest (circled in red) seems to activate the fan into running at maximum RPM; at the same time you may observe that taking pressure off the area of interest makes the fan stop immediately (or soon after, presumably because the plastics bend back into shape). I am not sure whether this problem is the result of the motherboard (which observably flexes) or that pictured screw or whether something is making contact underneath the keyboard, but I thought I'd share this bit of information with others who may be as frustrated as I am with this problem. I will be dismantling the entire computer soon to look closer into the issue.

it also appears that gently bending the laptop mainboard upwards (when the laptop is sitting normally on a desk, not upside down) stops the fan immediately.
