COOLER MASTER R4-L2R-20CG-GP Green LED Case Fan

Comment:
I bought 6 of these for my CM690 nvidia case and they work like a dream. 4 are hooked to the mb and the rest are hooked to the power supply. The green lighting has the right effect with the case, not overly bright. With 6 fans running, the noise is a lot less than my other pc running only 3 Aerocool 120 fans in an Apevia case.

ummm the lights are bright, and my mobo stays at 30c... *low for a mobo* so... I'd say they work :)

I bought 2.Had to find an 80mm fan elsewhere to match.Works great.

excellent as a case fan. specs are a little off: 23dB @ 2000rpm = 90CFM 19dB @ 1800rpm = 69.99 CFM (direct from Cooler Master customer service rep) LED's aren't overly bright so you wont be lighting up the inside of your case with it but does provide a low light 4 beam effect that looks very sharp especially through mesh grilling. these are build and designed as case fans NOT A CPU HEAT SINK FAN the higher the CFM the better intake/exhaust fan it is, higher static pressure makes for a better heat sink fan. (higher pressure between the fins = more heat being pushed off) my next build will have 2 of these in an NZXT BETA case, EVGA X58 SLI LE + i7 920 + Noctua NH-u12p, NZXT GTS 250. with all the mesh on the front and back these should give excellent flow. **remember it isn't just about having the most fans, t's about getting the right flow to swap out the hot air inside the case**

I bought 6 of these for my CM 690 and wow! The fact that the fans are black with the green led's make it just that much more aesthetically pleasing. Each single fan is Very quiet but once all six are going at full torque, it gets a little loud. But I don't give a darn They're awesome! I only wish they made 140mm ones.

Shame this item is out of stock again. I bought 4 of these for an over clock build and I just love them. VERY QUIET!!! and they move a LOT of air.. A must for those using air cooling, and a great bang for the buck as well!!!

Great cooling and can't go wrong with 120mm, bought green for my own PC, built another and ordred blue.

Comment:
As good as others I have tried at 3 or 4 times the cost, but much much quieter!

I have a couple of clients with old PCs with Pentium D processors that ran really hot and kept shutting down. I added one of these to each case and have no problems since. I was worried about the quality due to the low price, but they are very quiet, move a good amount of air and have that bonus green glow. Great bang for the buck! Glad I bought extras.
