COOLER MASTER R4-S2S-124K-GP 120mm Case Fan 4 in 1 pack

Pros: Helped lower my temps by almost 5 degrees.

Cons: A little loud but hey it's a fan!

Pros: These fans are extremely quiet. I have this 4 pack PLUS 2 even larger fans in an Antec Three Hundred Two case and I can barely hear it running. If you're looking to add extra fans to your case, toss these in there. You won't regret it. Unless of course you're looking for colored LEDs.

Cons: None.

Pros: Cheap, quiet, work with my fan controller, came with screws and they all fit in my case nice and snug like they were made for it and even better by average case temp is about 1 degree higher then the room temperature... Like Martha says - "This is a good thing."
For what these are, cheep case fans, they really are great fans.

Cons: 1 fan has an annoying hum when it's turned up above 45-ish% But I just use that as an intake on the door so it doesn't need to be running full blast.
Not the prettiest fans on the block but they have heart, darn it!

Other Thoughts: Jennifer Love Hewit is pregnant... I'm requesting all flags in the nation to be flown at half mast.

Pros: Cheap, Helps Improve airflow.

Cons: Somewhat loud but that's okay because I wear headphones.

Pros: -Quiet during idle and gaming mode
-cheap
-fast

Cons: -Does not pull enough air in

Pros: Very cheap (Even without the rebate). You just can't beat it for value. The fans are pretty quiet, too... I really have to pay attention to notice the difference in noise.

Cons: 3-pin connector, and me with no more space on my motherboard. Even with the cost of an adaptor, these come out ahead.

Other Thoughts: The screws didn't work for my case, but the ones that actually came with my case were fine, so... No issues. If you need some cheap fans for extra air flow, you can't go wrong with this set.

Pros: Simple install, very quiet, even running at full 1200 RPM. Came with mounting screws for all fans even though my case didn't require them. Fairly long 3-prong power cables, about 8 inches.

Cons: It would have been nice the the power cables were in a shrink tube or bundled together. The stock cable is ugly is each cable is loose of the others. Makes it easy to catch one during install. Other than that, works like a charm.

Other Thoughts: I paid well under list plus after rebate, this was a fantastic deal on name brand high quality cooling fans.

Pros: Easy to install. Quiet. Work great.

Cons: None

Other Thoughts: Got these to replace/add to my stock fans in my case. Only problem I had was installing the fans in the front. Had to move the hard drive and optical drive a bit. But that's because I waited until after it was built to add fans.

Pros: Price, quality, Newegg

Cons: none

Other Thoughts: Nice quiet fans

Pros: 4 pack of fans for great price

Cons: No molex adapters, only come with standard 3pin. connectors are short also.

Other Thoughts: I've bought fans before, and they usually have the molex, these do not however. Adds some extra cost to grab a few adapters if your MB does not support all those 3 pins.
