which fans are best
 

I'm thinking of upgrading my fans for my h100 but I am not too sure what to buy. There are so many fans. I know noctua's are favored by many but quite pricey. I'd like something that has lots of cooling power but is still fairly quiet. Doesn't have to be completely silent but I do like quiet. And a fair price as well.

What do you all recommend?

And where can I find a 240mm shroud?

Coolermaster R4-L2R-20AC 120MM Blue LED Case Fan 2000RPM 69CFM 19DBA 3/4 Pin - COOLERMASTER - R4-L2R-20AC-GP

these have quite a bit of static pressure and flow for little noise, and they come in a few colours

As Babr's already stated the Coolermaster R4's are really the best budget fan for use on a Rad or HS.
If you want to spend a little more, the Coolermaster Blade Masters go up to 3.90mmH20 which will net you a bit better peformance (though I don't know how loud they get at 2000rpm).

The blade masters get up to about 32dBA which on my 212 Evo isn't that loud at all with it in push pull with a turbine master. But if you get 4 together in push pull I would say it can get pretty loud at 100% since my excaliburs and turbine masters on my H100 on my main pc is pretty loud and the fans are only rated for approx 30dBA.

Nothing tops Scythe gentle typhoon AP-15's, 1850 RPM and no need at all to slow them down, I run 10 AP-15's in my open case, loudest thing is my graphics card fan @ 30% fan speed. They do cost more then your average fan, but I bet you money they will last longer then any other part in your PC. For a cheaper option yate loons are OK, but only last about 1-1 1/2 years, and are way louder then GT's.

Like the GT's as well, they seem to be difficult to obtain.

I have a little stash :whistle: LMK if you need a few.

I used a few but a you surmised at full speed they are too loud IMO. Though the R4's are not exactly silent at full either.
