3 x 120mm or 2 x 180mm for 360 rad

post #1 of 14
Thread Starter 
Hey guys...

I was checking Silversone 180 fans http://www.silverstonetek.com/produc...AP181&area=usa

and got me thinking... what do you think is best... 2 180's or 3 120's fans for the radiator? It has lots of CFM an a good static pressure too ( the 180s )

180 on a 120 rad is worse as most of the blades hang over the rad and the large center hub further reduces air flow. If you could figure out a converter from 180 to 120 it might have better CFM : noise but using push pull 120's would probably work better.

2.45mmH20 isn't really "good" it's more "average"

Still, a 3 x 120 RAD is easier to find, and you can get better 3 x 120 RADs.

120mm fans rule, don't assume bigger is better...I found the opposite when comparing 140s vs 120s..

Hmmm ... i was not expecting to put the 180mm fan in a 120mm rad ... it's a 360mm rad ... so i did the 180x2 = 360 ...

Well... bigger isn't better ... in fact, the bigger the fan size, worst is the static pressure.

It was just a doubt, sometimes the 2 180 fans could be a better bet


Btw, does the push-pull has any performance effect on a radiator? i mean... it really makes a difference ?

Yep, a bit more performance from push / pull. Check out Martin's test for details.

3x 120mmx25mm fans gets my vote

So... the best option would be a 3x120mm push pull configuration... didn't know that we can have a 20-30% performance increase with push pull.

Btw, i remember reading that the Scythe SFLEX 1900RPM, had a little more CFM than what was being marketed by Scythe... is this true?

I tried reading Martin's test but i fail to understand if that was true or not.

you can also do push or pull w/ a shroud.

You can't put two 180mm fans on a 3 x 120mm RAD.

Even a 360mm RAD designed for 180mm fans, isn't going to be easy to mount in most cases. You'll be stock with Silverstone cases, and even then, just a select few.
