P4 heating problems

HI!

After a lot of work on my rig (and frustrations), I decided to share with you my experiences.

A couple months ago I upgraded my rig, changed the MoBo, CPU and memory.

Bought 2 sytems (one for me and another for a friend) containing an ASUS P4P800-E Deluxe, an Intel Prescott 3.0 GHz (800MHz) and 2 sticks of 512 MB CAS 2.5 400 MHz.

From the beginning my system was like an oven, 60 degrees iddle and 78 degrees under load. Tried re-mounting the heatsink, using artic silver even bought a water cooling system to try to lower the temps.

Running ONLY Folding@Home, will bring the temperature close to 76-78 degrees, and if trying to play games o convert video, the PC will shut down.

Nothing I did or try, will bring down the temps, and at the same time, (almost a month of testing), i fried 3 PSU, reason unknow. So went shooping and now i have a Thermaltake PurePower 480 W, but the temp problems remains.

Went to my friends, and "borrowed" his CPU to try that, and ... SURPRISE!

The temps went down incredible!

Now I am running Folding@Home, 2 iterations of Prime95, surfing the web, watching video, working with office and running ThrottleWatch.

The CPU is rock hard in 2999 MHz, no throttling down, AsusProb shows CPU temp 53-54 degrees, the same as SpeedFan with 100% CPU usage on both cores.

So, my understanding of this is as follows:

Being both presscott CPU bought at the same time, same provider, both closed in original Intel box; using all the same hardware, MoBo, memory, Video Card, PSU, HD, etc; I conclude that the first CPU is faulty, and the second is OK; I have nothing wrong with my system, neither hardware nor software.

And I am sending the faulty CPU to be changed.

A note: when I swapped the CPUs, I used the heatsink that was provided with the same CPU, so the problem may be with the heatsink and not the CPU. (but is highly improbable, being the heatsink VERY hot to the touch, and now at 55 degrees with the another CPU, there is no problem touching it)

Hope this will help a lot of people with heating problems, try to install another set of CPU+heatsink and check the temps.

Any thoughts?

*** Note ***
I run the PC like this for almost 30 hrs, without problems, also playing games

Look at this picture of my desktop:


If the picture is too big, i will rezise it, but you will have problems reading the data
