Should my Case Fans be on Auto?

Hello,

 

Sitting at my PC today, I was thinking, Should I keep my Case Fans on Auto or Manual Speed? I have an NZXT S340 as my case, a Rosewill 140mm and an NZXT 120mm for exhaust, and an NZXT 120mm and a Corsair 120mm as intake. I keep them maxed out at their highest speeds. Is that necessary, or can I leave them on auto? They are a little loud. Any suggestions?

 

Thanks!

If your fans have pwm control, no reason not to use it. Fans at 12v are annoying lol..even a quiet 140mm Noctua is obnoxious at max rpm 24/7.

You can set the speeds manually, fine tuning a balance between cooling performance and sound levels. It's really up to you as long as temperatures don't get out of hand (which is rare nowadays unless you intentionally do it).

I don't have any fans I can control even set to reach max speed. All are capped to 80% or something along those lines. Its all about what your tolerances are for noise and temp limits.

HECK NO, why would you want that much noise, turn them down till you see temps rising  then run them there or use a software to PWM control them based on temps so the fans ramp down at idle and up under load, NEVER run fans full blast, that just noise for the sake of noise.

UPDATE:

 

So, I have put my fans on Auto using MSI Click BIOS 5. Temps are the same as when on full. A lot quieter.

 

Thanks!
