3 120mm Front Fans or 2 140mm?

[Nightz]

I was gonna get some bequiet sw3 but wondered whats best 3 120mm's or 2 140mm's in my Fractal Design R6 Case

[just.kamk /idle]

My 2 cents: seems like the case uses the bottom just to hide PSU and additional drives (correct me if im wrong). If you use more drives there, i'd might think about going for 3x120, otherwise 2x140.

With my case the top can open and i think hold 3 120mm's or 2 140mm's aswell so I might go 2 140's on front 1 back and then 2 top? but with the top ones do i have them pulling air in or exhausting air? or have 1 bringing and 1 pushing air out. Hope this makes sense

Thinking 2 x 140 intake and 140s on the rear and top/rear exhaust would be optimal

Thanks a lot for the help might be getting bequiet sw3 idk yet

Hot air goes up, so it makes more sense to use it as exhaust.

For a build like this, airflow isn't super important. All you need is a steady air current going in the front and coming out through the top and rear. You don't need to spend a fortune on Corsair MLs(although that'd look and sound great...) All you need is steady flow, don't overthink it.

Air naturally rises. That means bottom fans are always intakes and top fans are always exhausts. Front fans are always intakes because rear-intake isn't practical. Rear is exhaust because you can't add enough fans for good airflow.

I would run twin 140s on the front. A 140 is slightly less powerful than a 120. On average. But a quality 140 is still a very potent fan and most than powerful enough for your build. My go-to picks are the BeQuiet PureWings 2 for pragmatism and Corsair ML140 for looks. The PureWings range are paired-back Silentwings, but are still surprisingly powerful, whisper quiet(actually almost silent) and cost a fraction as much. As a matter of fact they're almost as quiet as the much more expensive Corsairs.

Corsair's ML140 has a sexy frame, lighting and it's very powerful. It's also extremely quiet. And extremely expensive. My case has MLs on the front for looks and intake pressure, Purewings everywhere else for practicality, and as of today Noctua IP52 Industrials up top to force air through the radiator.

thanks a lot I was looking at pure wings 2 and I did notice they are like £10 cheaper then silent wings 3 so I will probably go with them cheers

Sorry to hijack the thread some what but are Ml fans good for static pressure ? Example rad exhaust fans, wofley ? Cheers

I'd do the math before choosing. Look at the Airflow and pressure on 120 and 140. Using BitFenix Spectre PWM 120mm and 140mm Fans as an example

120mm Fan
Airflow 51 CFm
Pressure 1.88 mmH2O

140mm Fan
Airflow 56 CFm
Pressure 2.15 mmH2O

3x 120mm fan has a combined airflow of 153 CFM and 1.88 mmH2O pressure per fan
2x 140mm fan has a combined airflow of 112 CFM and 2.15 mmH2O pressure per fan

Unless you're pulling air through filters or a Radiatior the pressure is less significant so as 3x120mm fans move 20%+ more air I'd use them. 120mm are also a little quieter than the 140mm.

Will probably go 3 120mm bequiet pure wings 2 in the front and 2 140's top and 1 140 rear
As there is 6 fan headers on my board
