Fans running wildly, not even close to hot v2.0

[Multicore]

The problem:
The microprocessor fan is running wild at full speed & making a lot of noise.
Cleaning the dust off the PC did not make any difference.

Recently, i noticed erratic microprocessor temperature readings & i suspect their role:

The PC is an old HP Pavilion a1312 Desktop PC.
My posts in this thread are made using this same wild-fan PC
Specs Summary (by Speccy)
Operating System:-- Microsoft Windows XP Home Edition 32-bit SP3
CPU:------------- Intel Pentium 4 517 (Prescott 90nm Technology)
RAM:------------ 1.00GB Single-Channel DDR2 @ 266MHz (4-4-4-12)
Motherboard:------ Hewleet-Packard Asterope (CPU 1) 33 °C
Graphics:--------- Generic Television (1024x768@85Hz); HP m705 (1024x768@85Hz); ATI video (HP)
Hard Drives:------- 75GB Seagate ST380011A (ATA) 31 °C
Optical Drives:----- No optical disk drives detected
Audio:----------- Realtek High Definition Audio


Background info:
1) My desktop PC failed to boot (no BIOS/POST messages, no HDD activity, no monitor signal)
2) Replaced CMOS battery (didn't disturb anything else) - PC ran fine for 3 days
3) again, failed to boot
4) removed one RAM stick (didn't disturb anything else) - PC ran fine (a bit slow)
5) replaced the same RAM stick - PC failed to boot - again, removed the same RAM stick - PC ran fine
6) held the same RAM stick in slot using one hand (touching just the edges of the stick) while switching on the PC - EPIC STUPIDITY !!!
7) the PC booted but with the microprocessor fan running wild ever-since

1.Replace your cmos battery.
2.Replace both memory sticks so your computer will have newer ram.
3.You didn't specify if you have checked your cpu grease to see if it needed changing or not.

Please tell us what ram you have and what model/name brand.
Once we have that I can go out and look for better ram for your computer.

Check your BIOS settings to see if there's a temperature setting or fan setting.

Also, P4's are known to run very hot... that's just their thing.

1. Already did that, bought & put another CMOS battery, now have one in spare.
2. RAM is not bad, it is running fine since May 2013 except the fan noise
3. It is a stock HP OEM PC, never checked for it & checking=changing

The PC was purchased on 20 Apr, 2006.
PC-DDR2 RAM 266.5 MHz, but i do not want spare DDR2 RAM like the way i now have the CMOS battery, since i think the RAM is fine.

I have already checked BIOS settings, the OEM BIOS does not have any temperature setting or fan setting.
I have also used two different fan speed control software, but that didn't work either.
the fan speed control software made the fan speed erratic - slow & fast

Mobo temp 36 °C
HDD temp 46 °C
microprocessor temp 40 °C

BTW, Core Temp shows that the CPU temperature is 0° C:

I gotta give credit to carnagex on this one but he is right.
On coretemp check the tab called motherboard and copy the serial number here.
I'll check for any new bios revisions provided by hp that may fix it.
What you could do is look for some replacement fans if needed. :/

Have you ran Memtest86+ to confirm that the RAM is fine?

Try using RealTemp instead of CoreTemp.

I have already updated the bios revisions provided by hp (last one for this specific model was released back in 2007):


I searched intensively for a motherboard tab on Coretemp, but was unable to find such a tab.

Already tried RealTemp, before CoreTemp, but it returned this error:


Yes, i have run Memtest86+ & ran again to post these screenshots of 2 successful passes:

Well I don't know what else to tell you but this: Upgrade and move on. :|
I know you want this machine to work but believe me when I say this it ain't worth it.
Since you have a LGA 775 cpu and mobo we could do better and your case should allow different mobos.

All this under 150.00 bucks and well worth it if money is not much of an issue for you towards the shopping season.
