Or am I missing something? And what are all these small white pads? They seem to be covering different chips on the motherboard. This is the first time I ever saw a heat sink with thermal pad needed to cool down the motherboard. The grey pad was above the motherboard HM67 chip. 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. I deinstalled that and by now can't find it again.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. The last thing I tried was to install some daemon (by Intel?) that is supposed to insert NUL commands to regulate the CPU load/temperature. I tried downvolting via the intel-phc driver, but while the module compiles fine it doesn't seem to be compatible with pstate (I can't load the module). I tried to setup i8kutil to have control over the fans, but there is an open bug that makes the system hang every other second (see ). The NVIDIA card is disabled by using bumblebee.Īt this point powertop reports that almost everything is running in their deepest sleep modes for most of the time. Īdditionally I use TLP and intels pstate driver for frequency control (using the powersave governor by default). I already use the settings from Dell XPS 15 runs hot on linux. I already use some mechanisms to conserve power (see below). Especially the region where I rest my palms is quite warm. In my opinion this is too high to work comfortably over long periods. My Laptop is running quite hot (sensors reports ~50-60☌) during normal usage.
