Well, your friend is wrong, the Intel stock HS fan runs at 2700 RPM, that's what mine is doing on this P2.4-533 processor, and it's running at a toasty 32C right now. :) I just checked another system here, a Celeron 1.7g with the Intel HS, and it's fan is also at 2700 RPM.

As far as the pictures, you didn't do the one part of the case that's most important, the back panel, since that's where you need an exhaust fan!

Did you remove the cover and see how much the temperature changed after a couple of hours?

Ok it seems as though you had to remove the Power Supply to access the CPU? If that's that case, the CPU fan is pulling air directly off the PSU. Which can get quite hot on it's own. This could very well be the reason the CPU runs hotter than most.

I'm not seeing a place to add a fan in the back at all. I would suggest you seriously look into buying a new case. Spending money on a new case would be much better ( and cheaper ) than having to replace a CPU and/or motherboard.

NewEgg has some decent cases for not too much money.

Hope it helps.

Those are maximum operating temperatures. Nobody in their right mind would attempt to run a P4 at 70C. :) FWIW, it's doubtful that you can get a P4 to 70C anyway, since it has excellent thermal limiting, and will slow down to protect the chip. Tom's Hardware did an interesting test some time back, and removed the HS from a number of operating systems. The two AMD's went up in smoke, the PIII crashed but did not damage the chip, and the P4 just slowed way down to maintain a safe temperature.

That being said, running the chip hot means you're probably not getting the rated speed I would imagine.

The P/S is sucking air from the case and exhasting the hot air, it's not blowing any hot air onto the processor. I have to agree about the new case, if this one's running that hot, a new case with better cooling would certainly hit the spot.

John, when you get time, perhaps you'll enjoy this thread :eek:

Big? Its pretty much standard size for Higher end coolers, especially for those who want to overclock. Its bigger size moves air better.

Here.. take a look: http://www.geocities.com/nfaq/pics

But the heatsink itself is a rather out-dated design, and so my OCing is limited to about 200+ Mhz. Hey, I paid $8 direct from my distrubutor.

Some HSF have bigger fans... 92~120mm

Check this one out: http://www.newegg.com/app/Showimage...08-04.JPG/35-118-108-03.JPG/35-118-108-02.JPG



BTW: I saw the funniest thing on a site...

LOL... only a fool would bother with this! Any decent case will keep the HD cool... This "water cooled HD' unit is the only thing worse I've seen than the regular fan cooled HD coolers.... plus its about $60!!

- NOTE TO ALL: A well made case does NOT NEED a COOLER for the hard drive. Mountings fans on the bottom does little - as the heat is on the TOP part of the drive usually. Instead of spending $20~60 on a HD cooler, get a better case.

I still think that 80C (176F) is too hot for even an AMD :eek:

5000RPM is too high...

I've seen your pics... your problem is easy to see...

You've stuck a P4 system into a case designed for a PIII computer...

You have almost NO AIR FLOW for your drives as it looks like most of your VENTS to draw air in are from those littles holes in the back. And then the PSU is used to suck all the air out of the case.

Your case is your problem. With no proper cooling for your HD, it also become a "radiator" and builds up heat within the case.

if you want a SMALL case with good cooling, look at these three as they have GOOD cooling.

I have upgraded someone to #1, and I have worked with #3 - I've seen #2... but don't know how good it is... but I find any case I've used from the In-Win company to have very good cooling.

I didn't say it was blowing air into the processor. I said it looks like the air it is drawing in is coming right off the PSU. So it would tend to be a bit hotter right?
