Pentium 4 3.4E "Prescott" likes it hot

[dfgp]

Pentium 4 3.4E S478 1MB cache, factory fan
MB: Intel D875PBZ
1 ATI 9600XT VGA 3D
RAM: 1GB DDR 400Mhz
2 HD, 1 CD unit
Standard ATX steel case with two fans (Intake/Exhaust)

I hope some of you, savvy people, could help me and give some general advice on how keep this chip within its normal temperatures (Cooling setups? Known problems?).
I've had it just installed this past friday and when iddle, it stays around 48 - 50 C but under heavy loads the temperature goes up to 70 or more degrees, hitting the limit imposed by the software monitor from Intel (Which, by the way, its the only thing I have to check the hardware).
The reason behind this dumb question of mine is having some ground to justify my claims against the "technicians" (Oficial retailers of Intel) and to demmand a solution for this issue that worries me to the point of anguish. My old, trusty P4 at 2.4GHz never gave me a single problem running enclosed in the same case and sitting in the same MB, even in summer and squeezing every drop of power from it. Now is winter in this part of the world (20 C in the room)and my new brand beast can't keep up because it overheats! Without any stability issues so far, I must add. I'm terrified of burning up another $300 chip (Yeah, it cost money here), so please spare me a few moments and help me.

The Prescot chips run very hot but they can be tamed. It is impossible to dammage them by overheating as they just slow down and finally shut down completely before any dammage is done. We tested 4 of the P4 3.4 E chips completely without any heatsink, within 4 seconds they went up to 92C and then switched of, no dammage to the chips. If you have enough internal fans the Intell fan assembly is sufficient to cool the chips down. Here in Thailand we have an outside temp of 35 to 45 degrees C. Our processors run at 57C under 100% load. But we use a total of 8 chassis fan and the case is designed for proper cooling. Arctic silver is also a help for the heat sink compound. Originally without the chassis fans the CPU went to 85 C and started to slow down. I hope this helps.

Sorry I forgot to mention that our power supply has another 4 exhaust fans, so that make a total of 12 fans.

It's hardly the retailers fault that this chip runs hot.
Having said this, if we had sold this CPU we would have advised on the fact that this CPU needs a decent case and more than average chassis cooling.
I'm guessing that your present case just hasn't the facility for any more fans and it's general design just cannot cope with the super hot Prescott.
My advice:
New case, for example: The excellent V1000 plus from
Lian-Li, or similar latest generation with 120mm fans (this chassis has perforated design for excellent heat dissipation)

Also: if a traditional midi tower is used fit a good PSU that has a second fan internally above the CPU (these really do improve cooling)

Also NOTE: A FULL tower case runs vastly cooler than a straight midi (if you have the space)

Thank you, I'll see what I can do.

I have the same chip on my system, in fact I have 3 systems with this chip. I also had temps around 55c.
So I puchased the all copper flower heatsink from Zalman. not only is it much quieter, my temps are around 39-42c during full use.
