Problem with non matching fans on push pull config

post #1 of 5
Thread Starter 
I just bought these to go along with the stock fans that came with my kit: http://www.jab-tech.com/Scythe-KAZE-...m-pr-3945.html

The stock fans that came with the kit are supposedly 1700rpm (not sure on the cfm) and the ones i bought are 1900rpm and have a cfm of 110. I was wondering if it would be a detriment if i have the higher speed fans doing the pushing and the lower speed fan doing the pulling?

Am i better off with just one set of fans?

I think putting the faster spinning fans as push and the slower stock fans as pull is a logical idea.

Not knowing the CFM figure and using the rpm figures alone, the 2 numbers (1700 and 1900) do not differ that much (~10%). A fan generally has its rated speed plus or minus 10% anyway. So, unless the push and pull fans have a much larger difference, I would not worry it a bit.

thanks! so it won't decrease my overall performance would it? placing the lower rpm fans as pull.. what if they have significantly lower cfm?

I've been wondering the same, but with AP-15's in pull and AP-30's (maybe 29's) in push on a GTX360.
