I've been reading a lot that this laptop is prone to overheating and fan issues. I think I have the same problem, but it is more complicated for me, as I run Ubuntu 13.04 and not Windows, so pretty much no support for Graphics from Dell or NvIdia (I had issues installing the drivers). Anyway, my laptop isn't under much load, RAM usage down to minimum and same goes for CPU. My fan keeps running at an extremely high speed, but to no avail. I can monitor that my CPU is running at close to 100 C which is pretty crazy for me. The other thing is that I am living in Germany and not in the US (don't speak much German). In this case, what sort of action would you be suggesting to me?
One additional thing, my laptop is no longer under warranty (it's now close to 2 years old), though it always had these fan issues which became worse in recent days.
I have similar problems with my laptop, so posting here on your thread...hoping that someone will respond..:-)
My laptop was heating up a bit too much (temperature above 90’s in normal load, and sometimes shutting down after hitting 100C), so I finally decided to open up my Dell XPS 15 (L502X) and replace the thermal paste. I have few questions:
When I opened it up, apart from the thermal paste on the cpu (i7-2630QM) and gpu (Nvidia GT-540 2gb), there were several white pads, and one grey pad. The grey pad was above the motherboard HM67 chip. This is the first time I ever saw a heat sink with thermal pad needed to cool down the motherboard. Or am I missing something? And what are all these small white pads? They seem to be covering different chips on the motherboard. Does anyone know the width of these white pads, and grey pads? Are all of these thermal pads to conduct heat? Or some are meant to block heat? I think the white ones are meant to block heat, but I may be wrong.
Anyhow, after replacing the thermal paste (didn’t do anything with the pads, since I wasn’t expecting to see them anyway), the temperature of CPU and motherboard remains in 80’s C, and GPU in 70’s C under normal load (20 browser tabs, and some MS Office work alongside). So, although it is not in the dangerous zone (90s and above), it is still quite warm for not so intensive tasks. I have cleaned the heat sink, and fan etsc also. I also used good quality thermal paste (CoolerMaster Gel Maker Nano). And the the fan still works in an annoying manner with bursts of sounds, instead of constant sound. It is very annoying, and I rather have the fan working the whole time than these annoying bursts (fan on, fan off, fan on, fan off, and goes on like this constantly). Any solution to fix this?
I am also considering downgrading to I5-2540M (lower TDP, and dual core), but its not worth it if the fan is going to behave in similar manner. Please share your experience if you use any other CPU on this laptop. I don’t think the GPU is replaceable on this one?
I have narrowed down the annoying fan noise problem. It is something to do with hard disk. My XP215 (L502X) came with a 750 GB WD 7200rpm hard disk. I created an image of my system on a portable drive, and restored the image on a 500 GB Hitachi 7200rpm, and well, the fan noises were gone. I don’t know how and why, but the fan behaves much better. To make sure that it is something to do with hard disk, I used the same system image to restore Windows on another 500GB hard disk (5400rpm), and the fan noises were back on that one. So, the only hard disk (among the three that I have) without fan noises is the Hitachi 500gb 7200rpm. I can’t explain why is it so. It is not a Windows issue, since I used the same system image, and did not re-installed a fresh Windows 7. Maybe some sort of software incompatibility with some hard disks, or something else.
