Fan control on HP Pavillion dv7 1199el
I recently bought a new laptop and I'm now trying it out as a linux host for virtual development machines (mostly one at a time) in virtualbox.
this is my first try with linux as a desktop @ work, so far everything is working (almost) out of the box but I'm a bit concerned with fan speed management.
I installed several system monitors and they agree in reporting these temperatures (idle host and idle VM, cpu load about 20%):
cpu - mobo (2 sensors) -> ~33°C
what I understand should be the gpu -> ~45°C
and that's ok with me.
my worries start when cpu load raises:
sensors report constantly increasing temperatures going in the 45°C (cpu) - 60°C (gpu) range, with +7°C spikes
and that's with just 60% cpu load peaks, 30-40% bottoms for a few seconds (30-60 tops)
I can see something is happening with fan speeds, since before installing NVIDIA drivers gpu temperature got in the 80°C range in a few minutes while idle (that's dangerous btw..) but still, fan noise doesn't change noticeably, while at pc boot I can clearly hear the fan can spin much faster.
luckily I'm working on low load procedures at the time, but I don't know how much this will last..
I'd like the fan control to be more "aggressive" but I didn't manage to find any setting around (followed a couple guides)
For example I tried with lmsensors and ksensors but they seem to fail detecting any fan controller device and BIOS has just a "fan always on" option (which is enabled).
Distro is Kubuntu 9.04 + NVIDIA drivers
