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

Pros: works ,does the job , cooler master usually is known for doing this

Cons: no lighting effects but for the price i didn't expect this lol

Other Thoughts: recommmend

Pros: -Virtually silent
-Sturdy design

Cons: -None, but see "Other thoughts."

Other Thoughts: The length of wire from the pin socket to the fan itself is rather short. I'd say it's about six inches, eyeballing it. I have a Maximus V Gene motherboard inside a Coolermaster CM Storm Scout 2 case, and I used two of these fans in the front of the case for the hard drive. Unfortunately, the wire length won't reach the fan pins, so I have to use an adapter to my PSU. This is not worth an egg deduction, though. Just worth a mention.

Also, I got the pack on a great deal some time ago. I probably wouldn't pay $22.

On the whole, I'm very happy with my purchase.

Pros: Quiet hum, better airflow than most stock fans and very inexpensive.

Cons: these aren't pre-threaded, but that's not a problem

Other Thoughts: Just one of these fans is worth the cost you pay for all 4.

Pros: 4 fans for a great price! what else do you want?

Cons: i've heard complaints about these fans making noise, they don't for me

Pros: I bought my pack of fans from a local electronics store for a discounted price and I can't be happier. Fans seem to be so expensive. These fans move a good amount of air and are very quiet. I even decided to replace the fan on my 212+ since these are quieter and move the same amount of air

Cons: I guess they look boring?

Other Thoughts: Good deal, highly recommended for a budget builder.

Pros: All four spin smoothly under power.

All four are VERY quiet.

All four seem to move a good amount of air.

They have over a 3-year nominal service life (I'm hoping for longer, since my case temperatures tend to run low) and appear (retail packaging) to have a 2-year warranty.

They cost about $2.25 apiece after rebate.

What's not to like?

Cons: Others have mentioned the unthreaded screw holes (just pre-screw them before installation), shortish leads (though mine reached a full 12" from the fan body), and 3-pin connector (vs. 4-pin - but shouldn't the 3-pins work connected to a 4-pin male connector, just without allowing it to control their speed, which given their low noise level doesn't seem important to me?). None of those were a problem for my installations.

Other Thoughts: I've had no problem with Cooler Master rebates in the past, and with interest rates what they are won't feel unduly shafted even if this one takes a while to arrive.

Pros: Standard case fans. No threading at all, just pre-screw stuff first and it's no problem

Cons: none

Pros: No issues with the fan itself - runs as expected.

Cons: FOURTEEN MONTHS to be paid - a whopping $5 rebate!
Ordered in late January (2012), finally received the check in March (2013) ... and the check was dated a full month before it actually arrived in the mail. Really? How much interest did they make by "holding" my five measly bucks for a whole year?

Other Thoughts: Lost an egg for rebate speed, maybe I should have dropped two eggs? Google "xigmatek rebate" before you let the prospect of a rebate sway you toward their product(s).

Pros: Price.
They all worked out of the box.

Cons: A little loud but what can expect when you get 4 fans for under 15 bucks will be around 5 bucks if i get my rebate. :)

Other Thoughts: I wish Cooler Master or someone would offer a 4 pack of 140mm fans. :(

Pros: Pretty Quiet moves a good bit of air. Killer price. Comes with 3 pin connector. All hardware included

Cons: Could be just a tad quieter but I'm still happy!

Other Thoughts: Used them to replace the single 230mm fan on my HAF series case on the left side door. Now the fans blow directly on the video cards (Duel 7770's)
