After setting up a new system, I ran it today for the first time for about
4 hrs. During the beginning (within the first 5 minutes) the heatsink fan
rpm dropped to around 930 and the digicell (the mboard monitor software
suuplied by the mboard manufacturer) started the alarm. I immediately
swtiched off the system. Then restarted it. It ran fine for the next ~4 hrs.
Then I heard the alarm again and saw the fan rpm again dropping to 930 from
~2940.
The CPU temp was between 37 and climbing to 41 (celsius) when the fan was
slowing down. Throughout the rest of the time, the CPU temp was between 37
and 41. I was not doing anything major with the system - the first time I
was just starting and the second time I was opening a large winzip file.
Any ideas why this might happen? I am now scared to leave the system running
and leave the room!
Can this be due to voltage fluctuations in the main board?
Here is my system info:
AMD Athlon 64 3200+ with the standard retail heatsink and Arctic Silver 5
thermal pad (since I had to re-seat the CPU once
and could not find the thermal paste recommended by AMD in any local store)
MSI K8N Neo FSR mainboard BIOS v1.4
Antec TruPower 380 W PSU and Antec Sonata case
Leadtek WinFast NVidia GeForce FX 5200 AGP Card
1 GB Patriot Ram
160GB SATA drive Western Digital
1 BTC 52241M CDROM drive
1 standard floppy drive
Windows XP
Thanks for any help,
Shantanu Sen
