What fans work for pulling air?

[himeko123]

I just bought a used Mugen2 from ebay, it came with a coolermaster fan. I tried using the fan to pull air but the fan touches the heatsink rubbing against the metal. I was wondering what other fans would not have this problem and if this would be an issue with scythe fans.

Anyway it'll need to carefully adjust the fan position for pulling use so the fins of the cooler don't block to rotating fan.

I am using two Slipstream PWM on a Mugen 1 in Push & Pull. Also works with other fans and Scythe fans. If you still encounter problems you could add a rubber or silicon fan frame on the pulling fan to gain 1-2 mm distance. But never needed this at all when I correctly positioned the fan.
