AMD Athlon 5000+ X2 overheating

[ChrisR]

Hello!

I have a big problem with one of my computers: the idle temperature of the cpu is pretty high and when I start to use some applications, it starts to overheat immediately. The CPU is not overclocked!

These are the specs:

AMD Athlon X2 5000+
Abit A-N68SV, socket AM2, Nvidia Geforce7025/ nForce630a
1 GB RAM DDR2 800
Galaxy Geforce 6600GT 128 MB
NoName 460W PSU with no ventilation on the bottom part
NoName Case with no additional fans installed


CPU Temp IDLE is between 30 and 40 C. When I start a Skype Video Call and use at the same time firefox to view a youtube video, temperatures skyrocket at 80 C and the computer turns off.
If only use Skype, the temps are around 60-65 C.

Originally, I believed that the thermal paste was the problem, so I've bought an Alpenföhn Groß Clock'ner (which is very well rated at frostytech) and used Arctic MX2 thermal compound this time. The problem however, remained the same, even with the new cooler. I've repeated the process of applying thermal paste and reseating several times and I am sure, that everything is ok regarding this.

I noticed something odd: when the fan of the CPU Cooler is connected to the CPUFAN power connector on the mainboard, it does not start. If I plug it in the AUXFAN connector, everything looks fine. Why is that?
While the computer is running, if I plug the fan first in AUXFAN and then in the CPUFAN connector, the fan runs fine as well. It seems that it just does not want to turn, when it is first connected on CPUFAN on boot.

After reading on the web, it seems that there are only 2 remaining parts which can generate this problem:

1) The power supply

2) The mainboard


What do you think and what would you suggest me?

Are there any other ways to check if it is one or another?

Easiest and cheapest solution might be to simply change your heatsink to an aftermarket version. It doesn't cost as much as changing your motherboard or PSU but would help to reduce the temps. You may plug it in AUX_FAN connector if CPU_FAN does not work with the aftermarket heatsink.

Seems he already got an "Alpenföhn Groß Clock'ner" (?), but the problem sounds like it lies with the CPU fan header being dead on the motherboard (the fan is not working and the heatsink is thus only operating passively) or with the fan speed being set too low in the BIOS for the fan to start. Many fans have a start voltage higher than their maintenance voltage, which would explain why the fan will start if it's first plugged into the aux header and then switched to the CPU header.

In either case, OP, running the fan off the aux connector on the motherboard should fix the problem (sorta). You can run the CPU HSF off of any power source you want; it doesn't really matter what the label is. To potentially get the CPU fan header working properly again, you could also try resetting the CMOS to default settings.

Sounds as if the CPU fan header is dead. It is not an unknown occurrence. Just use the AUX fan header.

I was wondering what was that. I thought it was some kind of thermal paste that I have not heard before. Guess I should have done some Google-ing first. :hmm:

Could be that the CPU_FAN was unable to power the fan on it's first run. The stock fan on the Alpenföhn Groß Clock'ner seems to be rated at 0.58A(?). As a comparison the CM Excalibur is at 0.45A max or Scythe GT at 0.083A max. I think OP could plug it to the AUX_FAN header and it will still work.

That shutdown is the CPU doing it to save its life.

Intel recommend temps 40's idle and 50's to 60's c .

Your temps are good. Same goes for AMD .

I've had this exact same problem before. What I had to do was re-apply thermal paste but this time, I applied less and did not run into any problems. I could only assume that too much thermal paste prevented the chip from properly hitting the heatsink. So since then, I've applied a bare minimum of artic silver everytime.
