Advise on Cooling Fan 3x120 vs 2x140

If it were me I would look at all the fans in my budget range, compare CFM to the dBA ratio, PWM vs DC functionality, if my motherboard can support that many fans or do I need a splitter or two etc

 

In the end, size usually indicates decent CFM and lower noise (potentially) so 2x140mm may move a little less than 3x120mm...however the level of noise 3x120mm puts out is a much higher delta between them than the CFM performance between the two.

 

EDIT - or if I didn't care about noise, check out Static Pressure fans, get PWM ones so you can control the speeds (or you will hate the noise) as those move the most air direct.  Meant for pushing air through Radiators in PC cases etc.

Hi Guys, I just recently build my 1st PC (previously just own gaming laptop).

My build is using Cooler Master Master Box MB500 TUF Gaming Edition ATX Gaming Case come with Three 120mm RGB Fans.

2 of the fans in the front for intake and 1 at the back as exhaust fan.

 

I'm thinking to add more fans for the cooling my system as I'm planning to Overclock my GPU(Vega 56) and upgrade my CPU to the 3rd gen Ryzen CPU once it's out.

 

Do u think I should have 3x120mm for intake and 3x120mm for exaust OR  2x140mm for intake and 3x120mm for exaust is better for the air flow?

 

I'm still new in this area & your advise is much appreciated.

 

English is my 3rd language sorry for the grammatical error .

 

Thanks,

Khan

neither, spend that money on a better CPU cooler or GPU cooler. the fans will have a pretty minimal impact on temperatures

@Khan92 depends if the total CFM and dBA ratio is what you are looking for.

 

If you wanted all SP fans...boy you could move some air, and also want to wear ear plugs when its on.

Thank you so much for the advise...i will look into CFM and DBA even more .. more research needed from my side to understand on this things..
U been very helpful..

Have a great one ,Bless your soul :)

Interesting ...but im still to scare of water cooling solution..perhaps maybe after a few years of training building a PC i should be able to do it :)

Just an air cooler that isn't the stock AMD one is going to bring down temperatures quite a bit and reduces noise. Same for the GPU, there are several air coolers that you can slap on there to make it quieter
