Compaq CQ56 High CPU Temperature

Hi there,

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
txm@xpdnet:~>

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.

Best regards,
K. Dimov

Apart from software-tweaking fan speeds (which I wouldn’t recommend), the sequence of cooling (from conservative to more
interventional/expensive measures) runs along the following lines:

  1. Air-spray chassis and CPU fans (which you’ve already done). Perhaps reposition GPU card.
  2. Remove CPU heatsink fans, then air-spray the heat-sink and air-spray the fans properly.
  3. Remove CPU heatsink and fans, remove old thermal compound, apply new thermal compound, remount heatsink and fans.
  4. Buy and replace CPU heatsink and fans.
  5. Water-cool.

HTH

I’m not sure if that is a hardware problem, just because before openSUSE I had ubuntu with kernel 3.0 and the temp. was not so high.

C.F.U. didn’t wok at all. Nothing changed… :expressionless:

Any other help maybe ?

Oh boy, I just noticed my cpu is capable to run 64 bits OS, but my installation is 32 bits. Maybe that’s why CPU freaks out ?

All the new cpus are 64 bit capable but many prefer to run 32 bit OS
can check the “top” command in terminal/konsole and check which “process” is eating into the cpu cycles.

CPU Usage is at 26%
RAM Usage is at 58%

Running apps: FireFox, Skype, Konsole

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):

  1. Kernel change: different pattern of CPU usage in later kernel.
  2. 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.

@op- you can try and download one of the 64 bit live cds for openSUSE and use it for a prolonged period and check whether there is a performance improvement

Yep, that I did… still no change.
Seems like AMD likes to heat the room…

Anyways, thank you guys for your help, I’m looking forward to throw this thing out of the window…

Problem solved guys… Drove over the laptop with my Audi Q7, it’s history now. Bought a brand new Sony VAIO Tap 20.

Performance while Skype, XChat, Firefox & VLC Media Player running:

CPU Usage: 12.5%
RAM Usage: 785MB of 8024MB
SWAP Usage: 0MB
Temperature: 27 degrees

Again, thanks for your help!

Regards.

you could have given it up for charity :wink:
