I have a Compaq Preasario CQ56 (AMD V140 with 2GB RAM) and since I installed OpenSUSE, the CPU temperature reaches even 110 degrees.
When nothing is running the temperature is apr. 77 degrees, the fans are always at full speed.
I tried to clean the dust from the fans with spray (also opened to box, removed the hardware and cleaned), but dind’t work also.
Here is a paste of the current temp now (running only Firefox & OpenSUSE forums):
txm@xpdnet:~> acpi -t
Thermal 0: ok, 74.0 degrees C
Now I’m lost… don’t know what to do, any help to decrease the temp with even 5 degrees will be very much appreciated.
It’s very difficult to comment on why the temperature may be increased based on the information you’ve provided there. A
`top’ output may be more exhaustive but I’m not sure that will explain the answer either. I think though it does make
sense for 64-bit hardware to enjoy the benefits of 64-bit host operating system.
But, I can think of only two reasons for the temperature increase since Ubuntu (nothing to do with 32-bit vs 64-bit):
Kernel change: different pattern of CPU usage in later kernel.
Coincidence of worsened heat-dissipation at the time of OS change.
AFAICS the only way to exclude #2, is to dual boot into your old version of Ubuntu and prove that your CPU runs at a
lower temperature. Either way, you’ll be wanting to use the later kernel (and ideally 64 bit). Consequently, the
solution is the same no matter what. You have a problem with your heat dissipation and you have to correct it. The only
escape route I can see is if you now confess to overlocking your CPU, but that’s unlikely given your attempt at CFU
modulation. You need to get you hands dirty and relieve your CPU of heat accumulation and tweaking round the sides is
only going to reduce its lifetime.
