4 out of 5 eggsI thought I needed them!!

Pros: I bought these for a project of using them for one of my external drives that didn't have a cooler(fan) to it, so I was going to devise a way to keep it cool. Found another fan in the house that fits it better now I have 4 fans on standby! Great.

Cons: Haven't used then yet! will comment when I do!!

5 out of 5 eggsgood air flow and quiet

Pros: I have used these fans in 2 builds and i am really pleased with the air flow they deliver, while being much quieter than most case fans.

Cons: 3-pin not 4.
not pwm fans

Other Thoughts: the only downside is they are not adjustable, but it is offset by the CFMs and lack of noise.

5 out of 5 eggsCheap and Reliable

Pros: Great price for 4 great fans. Pretty quiet and they move a very nice amount of air. Not much else to say other than these fans are very functional, cheap, and reliable. Pretty rare to find those words put together in the same sentence. Used in a build for my in-law, and also use them in my rig as well.

Cons: Noise level may be a little higher than the pricier fans. None otherwise.

Works Well.

5 out of 5 eggsPerfect

Pros: 4 pack of Cooler Master Fans for 16 dollars is a hell of a deal. Can't go wrong, perfect cooling options.

Cons: Not variable speeds. (But they don't claim to be)

Other Thoughts: Exactly what I thought I ordered, the fans work great. I have only used 2, but will be replacing 2 more in my case soon. Great product, keep up the good work.

5 out of 5 eggsPerfect

Pros: Price is great, quiet, durable fans. 3 pin case fans, not molex

Cons: not controlled fans

Other Thoughts: These fans are exactly what they say they are, at a great price, and they're cooler master. Can't beat it. I have only used 2 so far, but my case is nice and cool.

5 out of 5 eggsCheap and Amazing!

Pros: - Quite silent.
- Cheap.
- Easy to install.
- Black, because I like black color =]].

Cons: - If you combine these with the fans you already have, maybe it will be a little loud. Make sure you install it with the right direction.

Here's the right way:
top=exhaust
rear=exhaust
front=intake
side=intake
bottom=intake

4 out of 5 eggsthey work fine

Pros: these fans work. they're not super fast or anything but for your buck, there is bang.

Cons: I probably could have checked the description more carefully but these fans have 3 pin small power connectors; seems like most power supplies these days have more molex connectors than the 3-pins, so ultimately I had to get a couple different fans and a couple adaptors to use these fans. my fault though.

Other Thoughts: make sure your power supply has sufficient connectors

5 out of 5 eggsA good deal for some decent fans

Pros: - They work and seem to move as much air as any other 1200 rpm fan I've used.
- A good bargain for four fans

Cons: -Sleeve bearing, but that's expected in this price range

Other Thoughts: I put one into a Fractal Design R4 case with noise dampening, so I can't hear a thing. Not a whisper. Not sure how it would be in a case without noise dampening.

I only needed one, but this was such a good bargain I picked up the pack to have some backups.

Like all fans, longevity will be the real test.
