2500RPM CPU Fan is this slow???

  Mysticnas 23:50 01 May 2003

i've just ordered this fan.

cooler master IHC-L71 Fujiyama

Fan Dimension 70 x 70 x 25 mm

Rated Speed 2500 RPM

Air Flow 20.5 CFM

Rated Voltage 12 VDC

Heat Sink Dimension 83 x 70 x 50 mm

Rca (ºC/W) = 0.4 (FC - PGA2)

this is some blurb from the website:

"Although it only rotates at 2500 rpm, it still performs because it is equipped with the dual heat pipes. It is designed for low noise environment with minimal loss of performance to cope with the cooling effects for high-speed CPU nowadays."

what can i do about the fan?

as you can see the fan speed is only 2500rpm. the only option i can see is changing the fan on the heat sink. how can i do this?

the fan is 70mm squared. most seperate fans you can get are 60 or 80mm.

checked most places.

It's not the speed that matters is the rate of air it moves. slower is better as it should be quieter

I agree with woody - slower is nice and quiet. I try to fit only themostatically controlled fans - a Celeron 2GHz system i built a couple of days ago had the fan going round at 1400rpm, and a CPU temperature of 29º.

The really important thing is keeping your CPU nice and cool, and going as slow as possible whilst doing it.

it only moves 20.5CFM.

i don't know why coolermaster discontinued the Everest fan. it had 6000RPM and shifted more than twice as much air! that's probably one of the silliest things!!!

It's not even the amount of air that it shifts that's important - it's how cool it keeps the processor!

It claims to be a novel design, that's more efficient - thus doesn't need such a fast fan - only trying it will verify if they're correct or not.

a way to fit a faster fan to it?

They must know what they are doing, they have been at it longer than us

but why on earth remove a fan that is just sooo brilliant!!??
