Cool Fan Verified OwnerVerified Owner


Fits nice and snug on my cooler master hyper evo 212 cooler. Quiet and keeps my cpu at lower temps than just having a single fan.
None so far.
Took a bit slow for the item to arrive but since I was not in a hurry I did not mind the wait as much. Nice packaging too! Works well as expected, would recommend!

budget cooling fan


price is right
nice red LED glow
easy to install
can be a bit loud.
I use these for HTPC so the noise doesnt bother me.
if you need a quiet PC than I would steer away, or just get 1-2 max.

Experience: 6 Weeks

Good for a cheap build; bad for a quiet build Verified OwnerVerified Owner


- Inexpensive
- Decent lighting effect
- Quite loud
- Questionable quality
They can be quite cheap (and I managed to snag some at half-off), the lighting effect is decent, and they do push a good amount of air through your tower. They are, however, quite loud, even at half-speed, and the intake fans on my rig are already starting to make additional noise, as if the bearings are having issues.

If you're throwing together a cheap build (as I did) they totally do the job, but they aren't for a high-end or silent builds. (I intend to swap them out and hang on to them as back-ups the next time better fans go on sale...)

Experience: 4 Months

Loud, Good Airflow, Nice colors


Good airflow
Bright LED
Good aesthetics, won't recommend if going for a silent build.
