Suggestions on a replacement H50 fan (Priority is: QUIET)

post #1 of 16
Thread Starter 
Hi, thinking about replacing my stock H50 fan (still working just want a quieter fan).

I know there is a ton of info and I even have the "Official" H50 owners club thread bookmarked which has massive amounts of info but at over 18,000 posts now it is too much to go through. So...

I need help picking out a new fan.

My main concern is being quiet. I am OK with no increase in cooling capacity and would even be willing to consider an increase of 1~2°C at load if its dead silent. Or if something is available that could better the cooling while still dropping a few dB that would be nice also. Also, I would prefer to stick with a 25mm depth unless I can easily find longer bolts for a thicker fan

My case is a HAF 922 which lets all the sound out and its in my bedroom.


Specs for the stock fan appear to be:

~30dB, ~59cfm, SP 3.57mm H20

The model AK174CB-4BLB cooling fan has a 50,000 hour life span and a twin ball bearing design. This fan consumes 2.2W when running at 1700RPM and has a noise level of 29.75 dB(A). The max airflow is 59.05CFM with a static pressure of 3.57mm H20.

Cooler Master Sickleflows, or they call it R4s. They are pretty quiet for high rpm fans (2000rpm). It does a decent job, and if you prefer non lights, i think they have ones without the LEDs too. Good luck with replacing your fan!

hey thanks for the quick response.

Wasn't even aware of that fan. Looks like SVC has it for $10 w free shipping now.


Anyone know about how many dB and cfm the stock fan are rated at? Also, I read a lot that static pressure is important but don't see that listed on any fans I'm looking at. How would I judge that?

Noctua fans are great...

For silence go with the Gentle Typhoon 1450rpm. Quieter than the R4's and still maintain best cfm/dba.

I would suggest the Gentle Typhoon AP-15 (1850rpm). They would be much better than the stock H50 fans also they're still very quiet.

Any particular model? Any personal experience with it on a H50?

K guys. Starting to do some research on it and I see gentle typhoon recommendations coming up a lot. Does the AP-14 push enough air to keep up with the stock fan? Its rated at ~46cfm vs. ~59cfm on the stock fan.

Also, I'm seeing pressure ratings for some fans on the SVC site but not for Scythe fans. I'm assuming they are good since they get so many recommendations?


updated OP with some specs for the stock fan also.

Here's the stats on the GT fans:


Also see Martin's testing to see how well they do on a radiator: http://martinsliquidlab.org/2010/11/...und-6-summary/

I've used a H50 with one (and two) of Noctua's NF-P12 fans. The fans themselves are virtually silent, but you're still going to hear the air moving through the radiator. Your only solution then is to use one of the low noise adapters you get with the fan, but that will mean less air, and less cooling capacity.
