Hello,

I have a 939 AMD 64 X2 4200 that idles at 30c but running Prime95 for 3 min heats up to 80c.
When I stop Prime95 the temp decresses instantly to 47c

I have a Gigabyte GH-PCU31-SD with Arctic Silver AA-1.75G. I applied it with the credit card method on the heatsink. And pea size on the CPU.

When playing World of Warcraft, or leaving Prime95 on.. temps have reached 100 and shut off. I have a side case fan blowing air into it. Rear fan taking air out.

Please please help.

Gigabyte GH-PCU31-SD well thats the heatsink I have.. I have a side case fan which is a cool master that blows air into the case.

Is this a recent development?

I assume your system is several years old, so it's important to clean out your case, fans and heatsink well. Make sure all of your fans are running at the desired speed (Or turn them up). Old computers build up dust and debris on fans and between heatsink fins, restricting airflow. If you have IDE ribbon cables, make sure they are not blocking airflow. If none of this helps, ensure there is good contact between the heatsink and CPU by reseating the heatsink on the CPU with new thermal paste.

The computer parts are farly old. But we just built this machine. So the case, and case fants are new. I cleaned out the heatsink before I reinstalled. I did reapply the thermal as stated above. I was thinking of trying Arctic Silver 5 vs Arctic Silver AA-1.75G I dont know if that will really make a difference or just waste my $10...

Seems to idle just fine... at 30c but when under stress or load temps keep rising and don't stop till the computer shuts off.

Different types of thermal paste should make a negligible difference compared to how it's applied.

Does your case have good airflow? Their should be an intake and exhaust, make sure your case fans are blowing the right direction.

clean all the dust from your heatsink. clean off the old thermal paste and reapply new stuff. I suggest against arctic silver 5, takes too long to cure and doesnt work that well in my experience. use Noctua NT-H1, no curing time and works better.

To me it sounds as if the cpu cooler is not adequate for the job, like it came from a 65w part and you're tryiing to use it on a 125w cpu.

heat sink is a piece of garbage/it's not cleaned right/the paste isn't applied right/it's not seated on the processor correctly/fan isn't spinning up right or not at all/turn off cool and quiet/processor is dying...... ??? pick one.

Or we could just mock you relentlessly for playing World or Warcraft until you decide you don't need a computer anymore.

UPDATE: Bought Arctic Silver 5 and cleaned out the heatsink (which was dirty...) but put in a single core AMD 64 3200. Started at 38c ran Prime95 for 5 min and only got to 45c.

So next test I am going to put back in the AMD 64 X2 4200+ with the cleaned heatsink and thermal see how it runs....

UPDATE: Cleaned the old thermal again. Put in the AMD X2 4200. Thin Thermal on both the CPU and HSF. Idles at 33c ran Prime95 for 5 min max temp 61c. Ran Prime95 for 10 min max temp 61c.

Going to play WoW tonight Ill let you all know how it goes... if it works then SOLVED.

then wait for 2 weeks till your AS5 is cured and actually working properly. thats why i dont use AS5 anymore, too long to cure and better options around for the same price. Dont know why people still recommend it.
