COOLER MASTER R4-S4S-10AK-GP 140mm Case cooler

Pros: Quiet and moves a lot of air . Comes with an adapter for molex.

Cons: Is coming with screws instead of grommets or at least to have the rubber edges for sound dampening.

Other Thoughts: Good deal for the buck.

Pros: They are super quiet, and move a lot of air.

Cons: what else woudl you want

Pros: Moves air, hasn't died, doesn't add much noise.

Cons: The rebate system unfortunately required me to have to send 3 different envelopes at the same time for 3 products in this promotion. Oh well.

Pros: quiet with good air flow.

Cons: 1 of the 3 is faulty. doesn't rotate when power until you touch the blades.

Other Thoughts: Decided that two were good enough anyway and using the bad fan in a non critical area... Personal fan! Over all I am pleased.

Pros: I bought this because the rear exaghst fan on my PC went bad so i bought this as replacement. the fan i had was 120mm so i went up to 140mm cuz i can fit it. and ive already noticed temurature diferences. with the fan i had (BitFinix came with the Bitfinix Shinobi XL case) my GPU would run about 29 degrees Celsius on idle. but with this fan its at 25! SILENT very happy ^_^ havent noticed much change in my PCU temps but im happy enough with my GPU dropping!

Cons: It wont make you breakfast in bed.

Pros: Easy in, quiet, moves air.

Cons: None so far

Other Thoughts: Definitely quiet. I have this fan positioned on the roof of the case "pulling" air. It is in a spot that if there was additional sound, I would hear it. The noise level of the computer hasn't changed since adding the fan. Which is good, all is still quiet!

Pros: Great case for the price.

Cons: none

Pros: Good airflow
Noise isn't too noticeable

Cons: None

Other Thoughts: This replaced a fan with a High-Medium-Low switch, this didn't have that, but I knew that when I bought it.

It works, it moves air and I don't need earplugs to sit near the PC it's in... what more could I ask for?

Pros: Strong airflow

Cons: These fans can be noisy. I have two as intake fans on my HAF XB case (in place of the stock 120 mm fans). Though they should both be running the same speed, I see up to 200 RPM differences between the two 140 mm fans that are in place. I'd appreciate consistency and quiet operation from a premium manufacturer's premier fans.

Other Thoughts: Just as a side note, if you're putting these in a HAF XB case like I did and Cooler Master says you can, be prepared to make case modifications to make them fit. With these on, the front bezel doesn't go back on properly. After using a Dremel to trim them down and the supports on the case bezel, they finally fitted. This is a case problem, not a fan one, but since this is the goto fan for that case, I thought I'd mention it.

Pros: As stated in my earlier review. Black, a basic fan, no LED's, $5 after the rebate.

Cons: You get what you pay for. I should know better.

Other Thoughts: I like the way CoolerMaster answers all the negative reviews. Giving you the impression that they care. What a joke. I have them telling me it is OK to run my rig without this fan in place. Forgive me if I do not want to. Find tech support for most companies a joke, had a guy at Corsair tell me that he runs an 6 core amd OC'ed and it reaches 86C at full load which he says is OK, so again forgive me if I do not want to take the advice of a CSR. Figure I will just live with the off and on clicking, it is doing it as I am typing this (not going to lie it is annoying), until I can find a fan I like. Then I will throw this in the garbage where it belongs.
