3 out of 5 eggs

Pros: Great Fans! LED brightness is just right! Move good air though my case.

Cons: I purchased 6 of these for my Rocketfish / Lan Li case, a little over a year ago. 2 of the 6 have recently stopped working! They pretty much froze up and don't spin any more.

Needless to say, I'm not very happy with the life of these Fans. My computer gets turned off every night, and they've not got any where near the 50,000 hours they are advertised to work for.

Other Thoughts: I was really happy with the fans, until they started going out after a bit over a years service. I don't think, I'll be purchasing any more of Cooler Masters Fans!

5 out of 5 eggsBeware Neweggs False Description

Pros: Best price to performance fan. Looks good, not too bright. Quiet for the amount of CFM it pushes, only thing better is one of those 25 dollar ugly black german engineered fans.

Cons: Need a fan controller if you don't want them scorching at full speed (so get one).

Other Thoughts: All the r4 fans are listed as 90 cfm, but they should be listed as 69. This is Newegg's mistake and not CM.

3 out of 5 eggsNot satisfied

Pros: Moves air good. Noise is fine with a fan controller.

Cons: Not bright enough.. The Red leds are almost non existent. I wanted bright ones. I should've read the reviews more thoroughly.. These are loud without a fan controller.

5 out of 5 eggsGood fans

Pros: Moves quite a bit of air. Have 2 of them mounted in Push/Pull configuration on my Prolimatech Megahalems.

Cons: None

Other Thoughts: Not exactly quiet, but they move a good amount of air. You can also control the fan speed by connecting it directly to your motherboard.

Red LED's are subtle, but look great!

5 out of 5 eggsUse these on your H50/H70 RAD

Pros: Fantastic static pressure, which means use these on a RAD for great results! Pretty red lights (not very bright though). Not too noisy!

Cons: LED's could be brighter?

Other Thoughts: I slapped 2 of these in a push/pull config on an H50 and it keeps my i7 950 temps in check through 5 passes of IBT on maximum.

5 out of 5 eggsSleek and Quiet

Pros: Quiet: comparable to my gentle typhoons, for the pressure, amount of air pushed and their noise level. I am very pleased. I've got three in push on my 360 rad in My 800D, and they make just a little more noise than my GT's did, but push a lot more air.

Cons: Noise may be a drawback for some.

Other Thoughts: LED's are not exactly bright considering the propeller is a smoky-clear (?) - its a dark, clear plastic, so the LED's don't quite shine. Regardless the effect is OK.

1 out of 5 eggsterrible

Pros: they spin, didnt show up doa.

Cons: There is no way these things are operating at 90cfm. This is just false advertising and I am really upset over this. I bought these to replace a couple fans i had already thinking it would be increased airflow, and it actually decreased the airflow due to coolermaster not being honest with there product specs. watch a rep come on here and tell me i need a fan controller. Why was this not made clear in your advertising? it said nothing about a fan controller. On top of them being under spec, they smell something horrendous. my room smells like burnt plastic because of these fans. im feeling sick right now as i type this because of the smell.

Other Thoughts: i cant stress enough how dissapointed i am in this product. and this is coming from a loyal coolermaster consumer. i love my haf 922 case, but these fans are just terrible. honestly i think cm should refund me the shipping on these because of the false advertising. keep it up cooler master and you will have no more loyal customers. i think im going to be returning these. too bad i paid for the extra fast shipping. what a waste.
