BIOS makes CPU burn?

post #1 of 11
Thread Starter 
I have a Pentium 4 HT @ 3.00Ghz (no OC) with 1GB RAM running Windows Vista Home Premium (my choice) and when I am in the BIOS the hardware monitor reports that the CPU is at ~72c+ but when I go into windows for a few hours and then come back into the BIOS the temprature is around 56c?

I know this is to hot for the CPU but I have tried re-seating the CPU cooler and applying more thermal paste, but still the same tempratures.

any idea's whats going on?

I am mega confused by this computer.

Upgrade's I have done to it:
Replaced the RAM from 2x 256mb DDR 266 to 2x 512 DDR 400
Uninstalled the IDE HDD and put a 7200RPM Sata.
I gave it a clean because it was caped with dust.
Put external graphics card to run aero (MSI Geforce FX5200 128mb AGP)

dont know how much cpu power the bios uses,but my i7 is always 3.2ghz in bios which mean its on turbo(which means more processing is required) but actually my chip is rated to run at 2.93ghz.....
doesn't know if any of this makes any sense though....

BIOS runs hot. Your temps are very high.

What's the ambient temp of your room?

Things you can do:

1. Buy this, it's a bargain.

2. Use this thermal paste: IC Diamond 7

3. Open the window in your room

4. Get PC out of direct sunlight

5. Give PC 6-8" of space for intake and exhaust fans

6. Vacuum your room regularly

BIOS always run hotter than at OS. With Modern OS like Windows XP/2000, a halt state instruction is given to the CPU telling it to do nothing. This makes the CPU run cooler.

Older OS like Windows 95/98 and MS-DOS do not have a halt state instruction. BIOS does not have this halt state instruction either afaik. That is why it runs hotter.
