MASSCOOL FDV12025L1L34 120mm Case Fan

Pros: Cool transparent red fans, good airflow, air feels pretty cold throughout. I used five of these in a recent build and it's chilly right next to the case.

Cons: Just a minor gripe and maybe I should've looked more into it, but unlike pretty much every other case fan I've used, this fan doesn't have a pass-through for molex power, meaning that each fan needs its own molex power. I didn't quite have enough, so I spliced the two fans on the side panel together, which was more work than I was expecting.

Other Thoughts: I probably would've gone with different fans had I realized there's no pass-through for molex, no fan chaining here. Adapters might be necessary, or splice some wires. Newer PSUs don't have many molex, but I was using an older one which had 4, which would've been enough had it not been for the old DVD burner which was IDE/molex.

Pros: Lots of airflow, quiet, nice and clean design.

Cons: None.

Other Thoughts: Would recommend for anyone who has hidden fans or has a red color scheme.

Pros: Removes air. System internal temp never goes above 30-40 Celsius

Cons: No LED Lol

Pros: Cost, under-volt quite well, no baring noise at lower voltage. Very quite at full tilt

Cons: None

Other Thoughts: Using 6 of these on a XSPC EX 369 Rad and seem to be doing a good job.

Pros: These fans blow a lot of air in which the flow rate is 52 cfm. That cools down CPU and other components reasonably well.

Cons: Noisy. I used 4 of these fans and the noise level is unacceptable.

Pros: 1) None arrived DOA (ordered 6). 2) They are great! 3) Better at blowing out air, then sucking in. 4) Best price around!

Cons: Well I'm not sure if this is due to having 10 fans in my system, but it is a bit loud.

Other Thoughts: System Specs:
CPU: i5-3570K
MB: Asus Sabertooth Z77
RAM: 8GB G.Skill RAM
Storage: 256GB Corsair Neutron Series
Case: Corsair Vengeance C70
PSU: Corsair HX750

Pros: -Cheap
-Quiet
It gets the job done, you're getting exactly what you pay for.

Cons: Not entirely a con: It pushes enough air but it's not going to blow you away (no pun intended).

Pros: They are good as exhaust fans and look cool.

Cons: Not good as intake fans. They could actually touch the case and scrape the metal when using as a side intake, or make really loud whining noise when they are used for front intake.

Pros: Silent, even went not controlled by motherboard. Price is just right on these fans, and a steal with free shipping.

Cons: None.

Other Thoughts: These fans have no LEDs and may not match your color scheme for your build. But they are by far the best available fan I can see out there. I currently have three in my case running silent, and will soon purchase more to add to my build as well as upgrade other desktops in my home. If you want LEDs, then good luck with that. Used these fans for my first build, and I have no regrets.

Pros: These fans worked perfect in my build

Very quiet
Nice looking
Pretty good airflow.

Cons: None

Other Thoughts: Love it!
