I made a build a 2-3 years back. It was a asus p5gdc delux mobo and a intel 530j cpu. This cpu is great and still is very fast. However, the stock fan sucks and I haven't bothered to upgrade it. Well at a time like this..I can't find any easily with simple searches. Anyone familiar with this cpu and what kind of fan/heatsink will replace it.

I am getting very frustrated as I underclocked this 3ghz cpu to around 2ghz with no change in fan noise. The fans rotate at rpms above 3000. The cpu temp hits 68+ all the time.

I read something about a Thermalright XP-90 ...I am not sure if this fits.

Any help is appreciated. Thanks.

I have an Intel P4 630 (I think the only difference is mine has a 2meg cache, but they are both LGA775 socket), and had the same problem as you. I was sick of the fan screaming like crazy, so I managed to do a little research and found a ThermalTake Blue Orb. My computer is now so much quieter overall, and my CPU has a much lower temperature. Mine wasn't as hot as yours, but I've noticed approximately 15 - 20 degree Celcius drop! This is an awesome fan! Mind you, it's so big that I had to remove my power supply unit to fit it on! Currently my PSU is sitting on top of the case with cords going through the side - not really safe, but I've put it in a good position and don't go touching anything! :blink:

So yeah, basically go looking for a CPU fan that fits the LGA775 socket . The one you have mentioned is compatible with the LGA775, I found the webpage here. This looks quite fancy!

Cheers :whistling:

I cannot even believe my cpu. It wasn't this bad before. When I first built it, I believe 70 was a max. I have seen this baby hit 78.

From what I have read, I understand this cpu naturally craps out heat (enormous amounts) but the fan is annoying as [bleep].

If I close my case completely, the hit builds up and the cpu temp becomes 81 easily.

I may need to invert one of my case fans so the air flow is opposite of what it was because this is killing me.

I was hoping at this point, these fans would be cheaper..they aren't.


Also, that fan looks nice...would it fit in my mobo. I believe the fans pushed in but these appear to be screwables?

Here is an awesome picture that shows how the internal air-flow of the case should work. I found it reading this article, quite interesting.

To answer your question, it probably would fit on your mobo, but it's a huge sucker and you'll need to check surrounding components. I didn't, so now my PSU has moved, as previously explained...

Not sure what you mean by this?

I use a Zalman 9500 which is quite and does a great job at cooling the cpu my 945 P-D runs at 3.75 and is cool at load and at idle 31c for MB and 29C for cpu at almost 80 degrees F in room check out Zalman they make good fans

That heatsink is good but those temps are unrealisticly low.
Look here

If a Intel Core 2 Duo X6800 will run 30c at 2.93GHz on that same fan, there is no way your Pentium D is running at 29c @ 3.75 unless you did some serious modding, which still wouldn`t translate into the temps you listed. The pentiium D is a rediculasly hot proc.

lol read it wrong, yeah the processors clock down when idle for a while thus becoming cooler. Now that I reread his post I see that's his idle post, thought he said load. :whistling:

I have check my temps with 4 different software and digital temp gauges and that is what they run at, believe me, I also thought they were off but they are right on the only thing I did was lap the surface of the Zalman to a mirror finish and use AS-5 with 2 case fans and a Antec SLK-3000 case . The bios on the board also reads the same temps as the Probe 2 temps and I had a P_4 and the temps were a lot hotter with that chip plus i have a P-3 that runs quite a bit warmer.

Lapping adds to the effectivness of the cooler, probably drops temps 5c, thinking about getting a new cooler and lapping it myself. That'll be a rainy day project.
