Specs: WINXP PRO, AMD ATHLON XP1800 & 1 GIG OF DDR RAM
Hi expert,
I built the PC in 2003, since then it been running pretty good, but it got pretty noisy cpu fan sound since it was built. I wrote down lots of topic to here and there to get rid off the fan sound, but I failed to get the right solution. Recently 04/23/2010, I installed a new SiLenX fan on top of the heat sink, and it worked fine. Right now I don’t have any sound al all, and the fan makes only 8-dba sounds. But the problem is that the CPU’s temperature is rising quickly from 35 C to 50 C. and I didn’t put any thermal grease before I installed the fan.
Under above those circumstances I have a question for you that should I had to put thermal grease underneath the heat sink.
AMD ATHLON XP +1800
Socket A (462)
Motherboard- k7s5a pro
front side bus speeds- 266 MHz
100/133 MHz ddr/sdr.
1 gig of ram
64 MB AGP, 1st HD Master Hitachi 80 gig & 2nd HD Slave Maxtor 40 gig
Thanks for any idea or solution!
Cordially,
Mgian.

I take it you removed the heatsink/fan from the motherboard, put a new fan on it, then reinstalled it? No fresh layer of thermal paste? There must have been something on the bottom of the heatsink when you removed it...did you clean it off or just reuse it? Is 50C under load or just sitting idle? If it's the 'at idle' temp, it's a bit high, but if it's the 'under load' temp, it's right where it should be.

Find your CPU here & read the instructions on how to properly apply paste:

Starting point it shows up 35 C & then within 10-20 minutes the CPU temp rises up to 52 C, and it stays over there, & a few moment later it goes down to 50-49 C. But if I leave my PC open 24 hours, do you think this temp could burn my CPU or not? Lastly please let me know the sign of CPU or system burning warning.

The old Athlon XP has no built-in thermal protection so it can fry if it gets too hot. The max die temp for most AXP's is 90C, so you have a long way to go, but if your CPU is running at 50C at idle, something's not right. Remove the heatsink, thoroughly clean it of all dust, remove all traces of the old thermal material, then apply a fresh layer of paste as per the instructions in my other response.

Dear folks,
I was not make sure about that the noisy sound of the fan is not great problem, because the noisy sound creating fan could provide better flow of air, what is really good for CPU cooling. Any way I bought the silenx fan for CPU cooling, it provides only 10 cfm airflow, for that reason it giving less cooling inside the CPU, and the CPU temp always was rising up to 50-53 C. After having done small research, I installed back the older Dynatron fan, and it is giving better airflow, and creates noisy sound, but the CPU temp rising up to 35-37C. is it good or bad?
Lastly, I am still looking for silent fan that could give better airflow.
Do you have any info about that kind fan?
