More Intake Or Outtake?

[Matt_2133]

Hello All.
I have a 140mm (2400RPM) FAN on my NZXT KRAKEN X41aio cooler, and 2 NZXT 120mm (1200RPM) FANs, how should i assemble these fans more intake or more outtake?

My idea was because the KRAKEN fan rotates with 2400rpm, to put that one on the front and the other two ones in the back (because front total rpm=2400, and rear total rpm=2400 (not sure it works this way though)). BUT thenif i put the 140mm fan in the front, the GPU will be getting only warm air...

Please help me with this, THANKS in advance!

So, intake is used for positive pressure. This is generally used to only pull air specifically through filters. It's, IMO, for long term use and for items that don't need AS MUCH cooling, such as servers. It's a less maintanence approach. This allows air to escape anywhere it can, but only intake through specified points.

High end systems are much better suited for more air output (Negative Pressure), as it quickly vents as much of the air as possible, but sucks in through any crack it can get.

So, which way should i assemble my fans? Thanks.

My suggestion would be to install the radiator on the front and use your top and rear fan as exhausts. Heat in that area tends to rise, so you don't want all that heat rising into your potential top mounted radiator.

My fans are set up exactly like scream said. Works great for me.
