Wich fan configuration?

[ayygurl]

Hello I'm preparing a very silent build, wich has like no fan except for the case ones. That's where I need help. I have four ideas of fan configurations for this build.

- First one would be, one NF-S12B Redux (700 RPM) from Noctua at the front and another one at the rear.

- Second one would be basically the same thing but with two fans at the front instead one.

- Third idea: one NF-S12A ULN again from Noctua at the front, and another one at the rear.

- Fourth idea would be basically the same thing but with two fans at the front instead of one (you get it).


What do you guys think? Oh and, if you have some other ideas, leave em' below, thanks!

1. If you want silence .... you should start by picking the fan with the best performance / noise ratio . That answer is in the chart here:

For a direct head to head between the Noctua and Phanteks, you can see here that when you replace the provided Noctua fans with Phantels fans on a Noctua cooler, at the same rpm (1200) temps drop by 6C. The Phantels fans are also usually about half the price of the Nocs.

2. The next think to think about is how many you need ... for a quiet system, for 140mm fans use (1) 1200 rpm fan for each 75-100 watts of component power.... for 120mm, use (1) fan for each 50-75 watts. Typical model build would be 90 watt CPU, 35 watt MoBo, 125 watt GFX card (say 1060) and say 30 watts for everything else .. say 280 watts ... I'd use (4) 140s for that build... Typically during idle fans could turn off (assuming you have a good MoBo fan control utility) and never exceed 800-850 rpm even when stress testing. I'm guessing that considering your alternates, you have less loading

3. Inlet fans have filters which restrict air flow, more so once dust begins to collect on them so air flow can be reduced by up to 30%. So a good rule of thumb is to have 50% more intake than exhaust. Otherwise you will create negative pressure and suck dust into the case the the rear case grille ... and carrying that dust will be the hot air exhaust from PSU and GFX card getting sucked back in to the case

4. Give the options stated, I would use (2) Phanteks PH-F140SP_BK 140mm No LED LED Case Fans in the front and (1) at the rear

If ya don't have (3) MoBo Fan headers available would suggest one of these. It provides PWM control of up to (11) DCV fans from a single MoBo header:

(6) of those fans may be used w/ the hub w/o using the provided SATA power cable
