Best Fan Case RPM

[CHEESYnachoMAN4]

I have 2 Intake fans that are 140mm. They are be quiet! silent wings 3 and the max rpm is 1000.

 

I also have 1 exhaust fan that is 120mm. Which is also a be quiet! Silent wings 3 fan except the max rpm is 1450.

 

I was wondering what is the best rpm to set the fans too if I’m using them as case fans?

Good day friend.  With out knowing exactly how much air your  fan config is pushing/pulling it is rather difficult to get a good answer.

 

Have a look though these LTT videos find the one Luke did on fan air flow, (sorry spoiler he stuffs the case full of stuff and it makes little difference to thermals)

what is a general good rpm for case fans? My case is a mid-tower and has some empty room in it also i am in a pretty large room with no obstructions blocking the pc's airflow and its on top of my desk

This works for me Positive pressure in fans 3 and 6. I have a preferance for a quiet system rather that a cooler system there are two additions fans attached to GPU when it starts to get hot they turn on.

Really though it doesnt really matter unless ur ambient is so hot..above 1000rpm is the norm.

but if its pwm try to increase it as much as u can until u got a nice airflow but acceptable noise..

CPU: i7 6700k

Motherboard: MSI B150M BAZOOKA

 

WHY...????

oh ok why did u say why?

because u cant overclock those cpu with those motherboard

I dont care much for overclocking my cpu

Then dont buy UNLOCKED cpu..

I got the k model because i knew i wasnt gonna overclock and it has .6 Ghz higher clock speed than the non K

Let us know how you get on ChessyNacho.

 

Setting your fans up optimally is one of those trial and error processes. It varies greatly from build to build.   Part of the fun of PC building all the tinkering.

If your case is designed well, it is fine to set it somewhere between 600-800 rpm for the optimal noise to performance ratio.

Anything higher doesn't yield all that much extra benefit unless you want to blast the air into your case for a dual GPU config.

As low as possible RPM without choking the hardware fans.

Depends personal preference and nothing more. I have mine at ~400-500rpm on low load. They will go up to 1200rpm on full load, which I've set to be max because of noise. There is no good or bad or best fpm setting. All depends on what you are looking for. Less noise means lower rpm. Better performance means higher rpm.

RPM is arbitrary and is dependent on the fan and usage scenario. Find a sweet spot that is quiet enough for your preference but also keeps your temps in check. Fan curves are a good way to keeping it quiet as much of the time as possible.
