[gentoo-user] big problem, small solution

[gentoo-user] big problem, small solution

[Philip Webb]

Hardware problems come up here occasionally & experiences deserve swapping.

Gentoo involves much exercise of the CPU, sometimes making it sweat a lot.
My AMD 2500+ CPU (installed 2003) has been getting hotter & the fan slower.
Here in the summer heat of S Ontario, where my workroom is  >= 25 C ,
it had been running at a steady  64 C  for a couple of weeks (was  55 C ).
When I tried to emerge GCC 4.1.1 , it reached  > 75 C  & the box died;
several attempts, the same auto switch-off.  No fans to fit at the store
& all available CPUs are 64-bit nowadays, ie build another machine.

So I opened up the box, removed the fan & the heat-sink,
blew & wiped all the dust away, smeared on some silicon heat-conductor
carefully kept from the original package 3 years ago, put it back together.

Now the fan is running at  4400 RPM  (was  4000 ) & the CPU is at  51 C ,
rising only to  58 C  while successfully compiling GCC 4.1.1 .
Hopefully, I won't need to build a new machine till well into 2007 .

I recently replaced the fans and heat sinks on my dual opterons to bring 
the temp down, I was also very much trying to bring the nose level down 
from the fans.

I used 2 copper heat fans with heat pipes from thermaltake, and put some 
90 mm fans on each cpu/heatsink.
I also put a new case around them to improve air flow.

You want more air being pulled out of your box then going in.
I manually monitor and control the fan speed and with the new setup I 
have been able to get the processor fans rpms down to 1800-2000, a real 
help to reduce noise, with the temp averaging about 46c when idle.

When I have done something, perhaps emerge some program, whatever, temp 
goes to about 50-52c.

Check the specs on your processor to see what the operating temp range 
is so you do not burn things up.

			Hope it helps,

I have the same kind of problem with my laptop (Athlon mobile 2400+).
It's normally working at 43-50 C but after some time it starts
reaching 55-60 C without compiling. Once it even shut down after
reaching 100 C while compiling.
Fortunatelly I blew it's air intakes with oxygen and it is working
normally right now. I advise you to clean the intakes two times a year
-- it will help your computer live long :)

So you invented a fan that produces air. Great. Get a patent!

Yeah, and when all the air has been pulled out of the box and you've got a 
vacuum then you'll see the temperature in there rising... ;)

I guess I should have worded it different to avoid such comments.

I'm sorry but such a statement is just plain incorrect no matter how you word 
it. But my reply was supposed to be humorous even if it didn't seem that 
way...

Well, I have a AMD 2500+ and mine doesn't run near that temp.  Just
plain old air cooling with folding running and I am at 37 and 27.  I
have a ThermalTake 12 on mine.

Why does everybody have these high temps??

When I checked out the specs for my Opterons the running temp was listed 
from 40-70, if I recall correctly, so i think I am doing fine now.

I have a Pentium IV 2.6GHz (HP pavilion notebook), I used to have temp
issues, specially compiling, also, the battery was being drained fast.
I followed Gentoo guide in acpi and cpufreqd, created some VERY
specific rules, and never saw my note get too hot again (73C is the
shutdown temp). At high load, it gets to 66C and the cpufreqd daemon
puts the CPU at 2.2 or 2.4GHZ, and the temperature gets stable, even
with the fans semi-blocked. This also granted more battery lifetime,
and now it stays 2 hours wake with no problems (before, iddle, it
would last 45 min).

Notebooks are usually hotter than desktops, also, when your room
temperature is about 30C, you will NEVER get 27C on your processor,
and, well, have you consider checking your sensors to see if they're
working fine (maybe checking the BIOS hardware monitor, if available),
cause I never saw a computer running 100% CPU load that does not rise
to 30 or 40C.

Yep, it is measuring right.  I just have good circulation in my case and
a good CPU heatsink.
