Hey,
My CPU is 57C/135F at idle, when running a my 3d application (I do 3d game programming), my CPU temp goes up to 64C/155F when running that ONE application (it's not very graphics intensive, but it does use quite a bit of RAM). I'm not even overclocking, and my stock cpu fan (intel) is running at 4500 RPM all the time - it's quite loud.

I have:
ASUS P4P800e Deluxe
Pentium 4 3.0c (Northwood) with Stock cooling
NZXT Guardian with stock fans

Problem: Max temp for northwood is 69C/157F, and when I run CPU intensive stuff (ex: play Far Cry, or open an EXE with notepad), my computer restarts.

I know the problem lies with my CPU cooler.

Here's what I want from the CPU Cooler:
-Cheap
-Compatible (can't be too big and break the motherboard, like XP-120)
-Quiet: My intel fans are driving me crazy (not really, but they're pretty loud, and it's kind of annoying.

My CPU temps used to idle around 41C/107F and at load (when I play games like Far Cry) at 57C/135F... which is now my current idling - and NO i'm not running any applications (Spyware...etc) that are bogging up my CPU, 100% sure of that.

So any recommendations for a CPU cooler? I'd like to keep my temperatures around where they used to be.

I don't think your CPU is hot because of a bad heatsink, because intel would only supply a heatsink that would keep the processor within their temp limits. They would not supply a bad one with their retail CPU's.

If you have been getting these temps since you built the computer, then the heatsink is probably installed wrong. Take it off, clean off the thermal compound, and reapply it with some Arctic Silver 5. If it has just started happening recently, then it is probably because your thermal compound is wearing out. You should do the same thing, take it off, clean off the thermal compound, and reinstall it with AS5.

The restart means this ios serious and not just a error of the sensors....

I would take it out and reaply thermal paste and clean all the fans...how is the case cooling???

The Asus boards (p4 i875) are actually more famous for having lower cpu temps reported so this is odd indeed....

Oops, i missed where he said the computer restarted. And your right, thats definately not a sensor error ir its rebooting.

3.0C's usually dont have much of a temp issue, so something is seriously wrong. Check the heatsink installation and make sure that it is installed correctly, there is a enough paste, and the clips are on right to apply enough pressure on the CPU core. However, as mentioned, getting an aftermarket heatsink and some AS5 would help alot in the temps and bringing down the noise (those stock intel coolers are noisey) :thumbsup:

I agree with above, the intel cooler is more than enough to keep that cpu @ 90F or so. Check and recheck the heatsink and also make sure the voltage is set correctly in the bios. Also, some motherboards are set to shut down at a certain temp, so if the bios was reading it wrong it could cause issues. Try turning off the overheat option in the bios.

I've done everything you guys have said except for the re-apply the thermal compound part.
Voltage is set correctly. Actually, I checked my case, everything seems to be fine. How often shoudl I reapply the thermal compound? I might have put too thin a layer before.

But I was planning to replace the stock heatsink to do some overclocking anyways. So my real question is: What CPU Cooler (heatsink and fan) should I buy? I'll also get the Artic Silver 5 you guys were talking about.

If you have been getting these temps since you built the computer, then the heatsink is probably installed wrong.

Nope, as I said in the first post, it was fine when I built it. It's just going really bad now.

Today I just bought and installed a Zalman CNPS7000B-Cu all copper heatsink and fan, I have to say I am a little disappointed because I still get the same temperature at idle and loaded- which is 30 to 33C and 45-50C...

I expected the temperature to be lower given all the good reviews of the Zalman heatsink/fan.

In addition, my PC actually hanged twice today after I made the changes when I am trying to encode a DVD....

Previously I have never got PC to hang this way.

Sigh...I don't know where the problem lies but the timing is really bad after I change a new PSU, new Zalman heatsink/fan and added a third Harddisk...

WOW those are temperatures (compared to what I have at least) - maybe you damaged your CPU with static electricity (yeah right ;), but it's possible).

What are your specs? That might help a bit.

If it is the stock intel HSF, then it should have had a TIM (foil with black goo on it). If you put thermal compound + TIM, this will make your CPU temps higher. Also, if you try to reuse the TIM (take the HSF off and then put it back on), your CPU temps will be HORRIBLE. If you take off the HSF, you need to totally clean the black goo off and put on fresh thermal compound.

Guys lol. What I want is a new heatsink/fan. I now know that thermal compound will work, but I wanted a new heatsink/fan anyways (quiter, and i want to overclock).

The best coolers on the market are the xp-120 and xp-90, but the xp-120 doesn't fit on many motherboards. Check thermalright's website to find out if it will fit yours or not.

If you want silence, the zalman 7000alcu is a very good heatsink that is almost silent on its lowest fan setting, and is still not very loud on the higher setting.

Lol man. I'm in the massachusetts, it's -7 degrees out there. And in the summer, my computer heats up my room even if the AC is on high. so my comp is off most of the time.

Newegg isn't a great place to buy heatsinks, they carry many and the ones they do carry are often overpriced. You can find the alcu version here. The reason i recomended the alcu version over the cu is that the alcu cools nearly as good as the cu, but it costs much less and is a lot lighter. The more weight, the more strain on your motherboard.

All heatsinks come with very cheap thermal paste that you should just throw away. AS5 is much better.

27 decibals, i believe, is very quiet. the 7000 series were designed for quiet operation, so they should be close to silent.

EDIT: Newegg does carry the alcu version, and i must have been wrong about their heatsink pricing, because its cheaper than the one I linked to above.

Wow. My search skills must suck. Thanks a lot - yeha and newegg is selling the artic silver 5 for $.50 less (not that it matters).

2 questions: I know more money doens't ALWAYS mean better, but
Arctic Silver 5 ($8.00)
Nanotherm PCM+ ($9.00)

Should I get the nanotherm instead? It seems to be abit... more liquidy. What do you think will last longer? (I don't want to frequently reapply thermal paste), and what's better?

If you say Arctic Silver, it's cheaper on newegg (newegg doesn't have nanotherm), should I get
3.5-gram( 1 cc. ) tube $7.59
or
12-gram( 5 cc. ) tube $13.49

Heh. For less than double the price I get about 3.5 times the ammount, I'll go with the 12-gram. Or what the heck,

Arctic Silver Premium High-Density Thermal Compound, Model "Ceramique", 2.5-gram( ~0.8 cc. ) tube $4.49

High density? All I care about is reducing the temps, and not re-applying this stuff for a while.

This will help a lot if you can tell me what to buy. Thanks,

Go with the as5. The xp 90 is the best cooler in my opinion. That's what I have in my computer and it cooled it down drastically.

Thanks guys. Ah well I'm getting the AS5.
Final question: How the hell do I remove this stupid "black goo" stuff on my CPU? Simply scrape it off? Or do I need a special solution thing.

Simple drug store or even a supermarket like Giant or something.

I think the Zalman coolers are very nice however i would take a good look at Thermalright which are a bit better than Zalman but a bit more expensive and involved.

Edit: You dont want to scrap it because you could damage the core, or scrape it which could make it uneven and it might not make contact with the HS properly.
