Help! Crazy P4 temps

If you'll see my sig, you'll know my rig. This thing has been really weird latley. First the harddrive problem (40 gig drive's free space adding up to 60 gig's, long story, basicly a 15 gig partition read out as a 38 gig partition. And a 20 gig partition read out as an 18 gig partition.)

But the scary thing is this.

My P4, acording to Asus Probe, is running at 72C Load :Q

I'm using the stock TIM and heatsink, will putting on some thermal grease cool that sucker down? Also, when does a P4 start to throttle? I thought Max payne was being a tad bit slow...

Also, all the ATI Demo's fail. They say error initiializing DirectX8, WTF?
Any help on the harddrive, CPU temps, or weird graphics card behavior would be *GREATLY* apreciated!!
 
1) Put some arctic silver thermal grease on!
2) Put a second case/PCI fan in!
3) Don't pay any attention to Asus Probe! It sucks!
4) Download Motherboard monitor and look to see what the actual temp is. I experienced inflated temp reports from Asus probe with my P4/Asus p4t-e combo. When I installed Motherboard Monitor it reported significantly lower temps.
 
Saltin is correct.

Assuming that the HSF is making proper contact with the CPU:

Major difference - second case fan (have one at the back under the PSU (ehxausting) and one at the front (intake)
Minor: - Arctic silver (it IS worth it though).
 
Saltin, i'm just going to put on some generic white silicon paste because honestly....
I Live in China, and it's impossible to get anything else here. Here a computer can cost 1/4 of someone's yearly income and nobody's going to pay 1/10th of they're monthly income (Imagine if arctic silver 2 costs 40$ over there) to get they're CPU temp 3 or 4 degrees over they're normal temps when nobody spends more than 10$ worth on a heatsink/fan. No insult to you, just telling you what i'm going to do. Thanks to all of you. I was afraid my CPU was going to die! Hehe. I can expect this computer, after silver compound, to be *really* idling around 40C and load around 50?
 


<< Is it possible that Asus Probe is reading the diode and MBM is reading a thermistor? >>

It is possible.

If you are using the Intel retail heatsink that comes with the CPU, the performance of this HSF is 0.53C/W. During full load, the P4 consumes more than 60 watts. The rise in CPU core temperature is:

Temp rise = 60 x 0.53 = 31.8 Deg C.

If your case temperature is 28 Deg C, the CPU core will measure 60 Deg C under load. (60 = 28 + 32)

Since you cannot change the physics or mathematics, any program that measures 40 or so degrees under load cannot be accurate.

If you use more powerful HSF, you can lower the core temperature by some, but probably impossible to get it down to 40 deg without throttling back the CPU. See the the P4 cooler review at VR-Zone Hardware.

I have had more than half a dozen Asus motherboards and always use the Asus Probe PC with them. The Probe is easy to use and accurate. I never see it different from the MBM if both are setup correctly.

However, MBM does not detect the hardware monitor integrated circut chip automatically until version 5.1. It is easy for the user or MBM to mis-identify the circuit and resulted in erroreous readings. When set up correctly, the MBM is as good as the Asus Probe, but without the real time monitoring display.
