HOT CPU!!! NEEDS TO CHILL

Anybody have any good ideas for an overheating problem? I'm running a pentium 4/3.4GHz 800M chip, and whenever I put any sort of substantial load on the damn thing it heats to between 71-73 celsius.
I've heard of Arctic Silver. Any suggestions on the fan? Is the stock fan the best one for the chip?
PS...I'm not overclocking.

Thanks for the help.

Wow, your P4 needs a new HSF immediately. There's recommended versions if you check the cooling thread.

Yeah, another overheating Prescott what else is new lol. Probalby the 550(3.4ghz 1mb l2 cahce). Those are throttling temps there. The stock heatsink really sucks, mine was throttling on the stock heatsink as well, even with AS5. Switched it for a thermaltake jungle 512 and temps dropped to the high 50's under load. Make sure you have good cooling in the case as well, an intake fan in the front, and an exhaust fan in the back.

Intake and outtake fans are especially important. Otherwise the CPU fan just blows very hot air over the CPU, which doesn't effectively cool the chip.

Stick a frying pan on it and save money on electricity by not needing a stove :p

You could get something like a sonic tower heatsink and then stick a 120cm fan on it and it will run Much cooler and will be virtually silent, also make sure u have good air flow in the case.

just a question...I have a Northwood (0.13) P4 3.06ghz running at 3.4ghz stock voltages 100% stability Prime 95 72hrs, I'm using the stock HSF...at full load my northwood rarely reach 50c (its in a small Antec 1600SL) and yet I hear all of these horror stories(like the OP's) of Prescotts running so hot even the prescotts are built on a smaller process (0.09)

why is that?..I would think that the prescott would run cooler since it is on a smaller process and a longer pipeline

Northwoods have about a 20-stage pipeline, Prescott about 30. The longer pipeline allows Prescott to clock higher, but with the higher clock speeds, temperatures went off the scale, too. Part of it is physics. There are limitations to how high things can be clocked. The industry is no longer chasing clock speeds, rather multiple cores: scaling out, rather than scaling up.

Also the smaller process technology in some ways doesn't help. The process technology is so small, and there are so few atoms making up nano-structures that atoms escape their designated paths, and this manifests itself in current leakage and heat.

The first Prescott I built I returned because it ran hot. I built another about 6 months later, by which time Intel must have done something to better control the temperature issue.

this should have reduced temps as the cpu is now doing less per clock cycle...it was the main reason that the P4 had a longer pipe line than the Athlon...to allow high clock speeds at lower temps.

I think I will stick with my northwood...at 3.4ghz it benchs just behind a 3.6ghz prescott any way....which is the main reason I haven't replaced it with a prescott despite my GA-8S648FX-L having support for them.

My Zalman 7700Cu has served me faithfully for quite some time now. I'd recommend that to anyone. The stock HSFs from Intel have just sucked lately and IMO are inadequate for 3.4Ghz and above.
