hiya all,

i need a fan 70 x 70 that shifts at least 40CFM of air. The usually come at 5000 to 7000RPM

It's a pain. I've tried to look them but i can't find any fans of that spec that are sold alone. Usually only come with a CPU Cooler.

Any help would be great!!!

Thanks

Nas

i've found this thermalTake fan.

but it's 80mm. is there a way i can get it to fit on a 70mm fitting?

got the heatsink i want....

the coolermaster fujiyama for the P4. it's all copper. and has daul heat pipes. they're filled with fluid which aids the cooling. but it's shipped with a lousy 2500rpm fan thats shifts 20CFM of air. :o(

i'm into overclocking you see. well starting to get into it.

the current heatsink supports 70mm fan as most P4 coolers do.

46 cubic feet of air per minute (46cfm) is a pretty large amount of air for a small fan.

The cubic root of 46 is about 3.5, so you are trying to completely replace the air in a container having sides of 3.5 ft every minute, with a single 70mm fan?

46 cubic feet is roughly equivalent to 3 PC cases, or one case every 20 seconds.

As with any fan, this is not achievable unless the inlet will allow 46 cfm to flow through it.

I estimate that an inlet that large is roughly equivalent to the entire front (or rear) end of a standard midi-size PC case.

Can you explain why you need to completely replace the air in your case every 20 seconds or so? With a little more information, we may be able to help you better.

"As with any fan, this is not achievable unless the inlet will allow 46 cfm to flow through it. "

as you see it is possible with a 70mm fan.

and 75cfm with an 80mm as in the TT fan on the 1st link.

the above 478 link is i believe your heatsink with fan.try contacting overclockers for just a fan

i have 3 80mm fans sucking are in.

and the reason, is that i'm going to overclock my p4 2.4 to 3Ghz.

water cooling is preferable but my budget and expertise (lack of) in oc doesn't allow it.
