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)??

A 30CFM fan will work, but,
unless you're looking for silence, then i would suggest something a little
stronger. I find the Thermaltake 90MM fan is great. It pumps 56CFM@35db.

That will work very nicely on your XP-90, and if it's too noisy, you can put a
fan controller on it. Yes an Antec 3 speed fan will work also, i would just try
and get 40 or more CFM ...but it really depends on what CPU you're trying
to cool. GL

i'm trying to cool an Intel P4 3.0E (Prescott 3GHZ)

I am looking for silence.. but if it's gonna make my CPU run too hot .. then i'll get something in between

right now i'm running on an Antec LED fan :

* 3 Blue LEDs
* Size 80 x 80 x 25.4 mm
* Weight 71.5 gm
* Fan Speed 2,600 rpm (avg.)
* Volumetric Airflow 34 CFM
* Acoustic Noise 30 dBA (at average rpm)

is that enough? or should I get something else???

Well, it should be enough as long as you aren't planning on overclocking it. The original Prescotts weren't exactly easy to cool...quietly. Make sure you have good airflow in your case also. GL

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
....

Fan speeds normally vary ie: 2654.. 2598..2654...2598..etc. But dropping to zero isn't right. Maybe the tach wire from the fan is loose, or is making a bad connection at the fan itself. I would try another fan, just to check, and if it drops also, then maybe a bad sensor on the mobo.
