Which is better 230 mm fan or 120 mm fans?

post #1 of 13
Thread Starter 
I have a HAF 932 full tower, i currently have fans intaking from top,front,bottom,and sides and exhausting from the back...My current set up is:

PSU on top 140 mm intake and exhausting from rear
2 x 120 mm next to psu intaking air
230 mm on front by my HDD's intaking ( should i switch this to a 120 mm fan?)
2 x 120 mm fan on bottom intaking
230 mm side fan intaking ( should i switch this to 4 x 120 mm fans) ?
corsair h70 water cooling in a pull-push config exhausting out the rear.

Pretty much im intaking cool air all around and exhausting the warm air from the rear on my chassis. To get overall optimum cooling performances should i go about switching my 230 mm fans to 120 mm? What is everyone's opinion on this?

230mm is quieter than 4x120mm.
Or should be.
the 230mm would be quieter

I dunno, large fans are usually quite loud.

I think 4 Gentle Typhoons would push a ton more air... and be super quiet.

Some are quieter and some are I think.

I have had 230mm fans that are very quiet. Some others are loud.

If it's quiet, then there's no worries. Is it worth spending $12-15 a piece for four more good fans? That's your call. If you can find out how much air the 230mm fan pushes, you can compare that to four fans and decide for yourself.

Well the 230 mm fans i have are 19dba @ 700 rpm they pretty quiet, however performance wise which one will cool more a 230 mm which has a nice chunk of radius or 4 x 120 mm which are also 19 dba @ 2000 rpm ? should i switch all of my 230 mm to 120 mm or keep them?

That's the question isn't it?

I personally think 4 120mms would push more air... but is it worth spending on four extra fans for a slight difference? That's your call. Maybe someone more knowledgable can drop in some more educated opinions.

19dba @ 2000 rpm sound a lot like CoolerMaster R4's.

If they are stay the hell away from them. There is no way in hell the R4s are 19dba. I have only one in my HAF 932 and it's easily the only fan I can hear. And that's with 3 230mm's, 2 140mm's, and a total of 3 120mm's.

That thing is balls out loud at full speed compared to my Scythe S-Flex E and Noctua NF-P12.

I would stay as far away as possible from them.

Unless of course you like to hear a buzzing noise in your case at all times.

regardless of which fans you decide on you should look to have the top fans as an exhaust, not intake.

Top and rear exhaust and bottom, side and front as intake.
