Overheating and replacement of CPU fan

December 14, 2009 at 09:17:57
Specs: XP, 2.5 gb ddr2
Problem: 1) CPU keep over heating
2) Fan sound loud

I boot up PC and a screen written my PC
previously shutdown due to thermal event.

Next, my PC's fan sound are loud and maybe
from GPU or CPU fan. Dont know how to
check it.

But i think that maybe CPU fan run too fast.
The data following is from speedfan.exe

CPU:4422 RPM
GPU: 53 C
CPU die: 74 C
Motherboard: 62 C
Motherboard: 46 C
ICH: 46 C
MCH: 49 C
HD0: 35 C
Motherboard: 47 C
Core: 70 C

I just boot up PC for 1 hour but already getting
high temperature. Can i cure this problem if i
replace my CPU fan to C/MASTER GEMINII-S

Q1. What exactly is your motherboard or system?
Q2. What temps are reported in BIOS?
Q3. How does cooling air get into your case? A little slot on the bottom front or a nice big hole in the lower front of the case? Case sitting on carpet?
Q4. Power supply fan running? Any additional fans at the top rear area of the case?
Q5. How old is your machine?
Q6. All fans running?

Your entire system temps seem high to me indicating cool air isn't getting into the case or hot air isn't getting out.

SpeedFan can't always be trusted either...that's why I ask for temps as reported in BIOS.

Don't get in a hurry to replace the heatsink; probably not necessary.

Follow the advice from kuwese for cleaning dust from the interior and exterior of the case. Canned air should be used instead of a vacuum cleaner or air compressor.

q1: my motherboard intel dp965lt, pentium d 945 3.4ghz
q2: My bios i think cannot see temperature.
q3: case sitting on computer table, below monitor got a slot
for case, cooling air maybe get from behind of case, any way
i put link that for 2 years ++ but no problem happen.
q4: PSU fan are running, no additional fan and top rear area.
q5: about 3 years
q6: ya all fan running, but the fan sound are loud, i think at
beggining already like that.

this is the reading from speedfan ( overheating and i boot again)

CPU:4432 RPM
GPU: 54 C
CPU die: 85 C
Motherboard: 66 C
Motherboard: 46 C
ICH: 67 C
MCH: 51 C
HD0: 30 C
Motherboard: 47 C
Core: 71 C
