Cooler Master R4-EXBB-20PK-R0 Excalibur Case Fan - 120mm, Barometric Bearing Item#: C283-3082  |  Model#: R4-EXBB-20PK-R0

Great fan!

This is a great fan with lots of airflow, but not alot of noise!

Great Liquid Radiator Fans!

As many people who have purchased the Antec H20 920 Liquid Cooler we went searching for a four-pin fan to replace the stock fans (which sound like a jet engine when run at extreme). I use two of these cooler master fans have to cool the radiator for my liquid cooling system and they work to perfection. Even at extreme setting the fans are still loud, albeit nothing compared to the stock. I clean them weekly with air blasts and monthly with an old toothbrush and air. So far they are still running flawlessly! Great quality four-pin fans for your hard earned dollars!

Best Fan I Have Ever Used

If your looking for something to MOVE air look no further, this thing does the job of 2 lesser quality fans by far. If and when this fan dies, i will buy another of these or whatever CoolerMaster comes up with next.

Plenty of air...

Got 2 of these and they provide plenty of air flow. The one mounted on the side is quiet enough however, though it is NO fault of the fan itself, the one I mounted in the front is way too loud so I'm replacing it with a Cooler Master 200mm fan and putting this one in the rear of the case for exhaust. The 200mm fan (if it fits in your case) runs slower, is much more quiet yet provides plenty of air flow. As usual, this site and Cooler Master Rock (but not too loudly)!!!

Impressive

I've owned three of these fans for around two years now and I use them as exhaust fans in my cases. They work quite well and move lots of air, though they are not the quietest fans in the world, which is probably due to either noise from the airflow itself or the turbulence created by having holes in the fan housing. Probably not the kind of fan you'd pick up if you are looking for a "quiet" PC. Mine usually spin at 2200-2250 RPM at full speed, and they move more air than the comparable D12SH-12 that is rated at 88CFM, I'd estimate these fans move at least 90-95CFM of air.

Less static pressure than the R4 yet $6 more

They boast that these are awesome for radiators or high end cpu coolers but the reality is that the fan that comes with the hyper 212 the R4 is actually better because even at a lower flow rate which also means quieter it has more pressure. This is probably because of the holes that are in the side of the Excalibur I'm sure there is a lot of pressure loss there.

Great Fans

4 pin so my MB can run them, quiet and move alot of air .....what more could you ask? got mine at $13 each ....would still buy more if I needed em

Good Price and Extreme Airflow

ive had these for 3 weeks now. i have them with my h80 cooler as a push pull config. i love the extra protection around the wire. kinda loud but pushes lots of air. will buy more

good air movement and not that loud

recently purchased this fan, set it up as cpu fan on CM hyper 212+ keeps it cool and run quiet my CM led fans are louder than this thing, only issue i had was its 4 pin and have none on MB so had to use both adapters that came with fan till i get a fan controller none the less great product moves air nicely and isn't that loud would recommend to anyone will be getting more for case
