CPU Temp

[eeyno619]

I recently installed a 2.4Ghz Pentium 4 Prescott processor on an Asus p4p800. When installing I scraped off the thermal padding on my heatsink and applied Arctic Silver to the processor. My concern is that the processor temperature is too high. It's running at over 70 degrees celsius.

Can anyone tell me why it's so hot?

Welcome to SysOpt

Are you overclocking at all? What were your temps before you applied AS? Also did you make sure to only apply a thin layer? Too much AS is almost as bad as too little..

Hey MJC,

I'm using the built-in overclocking utility on the mb at a setting of 10%. I built the computer from scratch, so the processor has always been running with the as applied. I applied the amount recommended on the as website ... I hope; it was kind of hard to tell . Also, I'm using the stock fan that came with my P4. My old computer, however, has a thermaltake fan that's about 3 years old. Should I be using that instead?

For overclocking, i would highly recommend that you don't use any windows based applications. They are notorious for screwing things up. For overclocking, make all your adjustments in the BIOS only. Quite possibly the reason your temps are so high is because you are using the stock heatsink/fan. For any type of overclocking you will almost certainly need improved cooling. What model of thermaltake cooler do you have? If it is rated for your current CPU i'd give it a shot. For now, reset to stock speeds, and see what the temps are then.

Yup that's his prob. right there.

eeyno619, get a better HSF, when you replace it with a new one at the same time just take your CPU out, clean the artic sliver off it (you can use cotton swabs with regular Shop and Stop Isoproyl Rubbing Alcohol) and then spread new artic sliver on it and seat the new HSF.

Try not to let the HSF slide around on the top of the proc when you're seating it and dont spread it too thin... Better to be a little think than too thin. Just make sure its even and you cant see any die showing through it

Nah, its not really the fan to be worried about, you're in greater need for a new heatsink... check out the Thermalright SLK-948U



or the

Thermalright SP-94



I would go with the SLK-948U and you can practly pick out any fan you want to go with it

That is a very good heatsink for overclockers...too bad it isn't exactly 100% AMD compatible for people like me..

Prescotts are notoriously hot. Like the others have said, get a good heatsink. Intel stock ones are only meant for use at stock speeds.

Hey buddy, I hit 2645MHz with a XP 2600 with those heatsinks...

Thermalright SLK-948U = Intel and/or AMD
Thermalright SLK-900U = Intel and/or AMD
Thermalright SLK-900A = AMD Only

I was using the 900A with a 90mm Tornado! Now I'm water cooling it though

[eeyno619]

Thanks for the tips everybody.

I went out and bought an aerocool fan/heat sink and have overclocked to 2.88 Ghz so far. The temp is holding at just abouve 40.

Thanks again.

I think he means AMD64 as those heatsinks wont really fit right on the AMD64 sockets.

[MJCfromCT]

I thought I remember reading that on some AMD XP mobos the thermalright heatsinks just won't fit (most notably asus boards)...

[dragflameson]

Oh I didn’t know you where running A64...

They fit my Abit fine. Their website lists the boards they're compatible with

[Damins]

The thermalright xp90 is used for754 939 940 478 and has no problems so far with any board. Here is the quote from their site .

XP-90 is designed to fit all AMD socket 754/939/940 motherboards and Intel Pentium 4 socket 478 motherboards. So far, we have not found any board that is not compatible with XP-90. If you've found any, we would appreciate if you could report them to here.

And its a pretty cheap heatsink for a thermalright .
