CPU Heatsink Fan Question

[earth4x]

I just bought a thermalright xp-90 and I was wondering... will a normal Antec 30cfm fan work great on the heatsink? or should I buy a 3 speed Antec fan(the Antec Tri-COOL)??

Using a Tri-cool for the CPU heatsink fan would be kind of a pain in the butt. You've got to switch speeds manually, so you'd have to open the case up if you wanted to change speeds (the switch cable is only about 3-4 inches long).

I'd get a low DB fan if you're going to run it 12v all the time, or get a higher one and let the motherboard/bios/speedfan control the speed, or a high one with some other sort of speed controller.

Recommendations aplenty on the forums.

Grab an Arctic Cooling AF9 and plug it into the motherboard. Should work very well. However, the 30CFM Antec would do fine as well.

I have a couple of questions...

I bought a 34CFM Antec 80mm fan and right now.. if I put my hand over the cpu fan itself.. I get a good amount of hot air coming out of it .. is this normal or should I only get a very very slight breeze (I want the fan to push air towards the heatsink)

Also... should 34CFM be sufficient enough to run with an Intel p4 Prescott 3ghz... because I want something silent while it still makes my CPU run cool all the time.. should I get this instead : http://www.thermaltakeusa.com/product/d...fan/perfectlight/blueeye/blueeye-1.asp


thank you!!!

Do you have the fan blowing into the heatsink or out? It seems like you've mounted it wrong. It should push into the heatsink.

Whatever you do, don't get a Thermaltake fan. They are almost damaging to the ears and just about everyone here hates them.

I Think I did mount it wrong.. i'll check on it tomorrow

but.. do you know any good cpu fan? because I want something quiet and really good at the same time and can't seem to find anything :/

Like I mentioned before, Arctic Fan 9.

I'd recommend a Panaflo M1A with that heatsink 48cfm, still only 30dba.

Is it normal when I run a program like SpeedFan or Everest or MSI Core Center the CPU fan RPM indicator usually goes like this :

0 RPM
2654 RPM
0 RPM
2347 RPM
....

Yes, that just means some of your fan don't support RPM monitoring. Look in your case-do all of your fans have 3 wires coming out of them or just 2? If its just 2, then they cant report RPM.

Freezer64 Pro's fan also occasionally does the 0RPM, 2344RPM, then down to 2280RPM. Sometimes it works, sometimes it doesn't. I found that if you run it at full speed, it'll usually be normal most of the time.
