My Laptop is running quite hot (sensors reports ~50-60°C) during normal usage. In my opinion this is too high to work comfortably over long periods. Especially the region where I rest my palms is quite warm.
I already use some mechanisms to conserve power (see below).
I already use the settings from Dell XPS 15 runs hot on linux .
Additionally I use TLP and intels pstate driver for frequency control (using the powersave governor by default).
The NVIDIA card is disabled by using bumblebee.
At this point powertop reports that almost everything is running in their deepest sleep modes for most of the time.
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 https://bugs.launchpad.net/i8kutils/+bug/1179282).
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).
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 deinstalled that and by now can't find it again.
Is there anything else I could try to reduce the temperature of the laptop? Or anything else I overlooked when trying to get i8kutils and/or intel-phc working?
