upHere 120mm Case Fan PWM 4-Pin High Airflow Rainbow LED for Computer Cases Cooling,3-Pack,NK12CF4-3

Excellent value. Attractive and relatively quiet even at full throttle.

Fans are noisy starting at around 50% but move air very well. They look good and keep my pc cool.

The color on these is very bright and will add some pop to your pc build. If you want to control these colors in sync, you may have to purchase a hub to connect into your color controller 3/4pin connector on your motherboard. In terms of noise, you can definitely hear the humming of the fans. It's not so loud to the point where it is a big annoyance, but for some of y'all that want silent builds; this may not be for you. I'm going to give five stars for the sheer fact, I wear headphones 95% of the time so this won't annoy me too much.Edit 2/21/21I have had these fans in for about a week, and they have increased in sound. I can now hear these through my headphones at 40% volume and can be distracting at times when wanting to watch shows or listen to music. I have now dropped a star to reflect this update. I still think for $5-6 dollars a fan they do well for what they cost. They still look amazing, but the sound is something that can be fixed on the next generation of these fans.

works great

I’m reviewing the PWM model that claims 86 cfm. Most 120mm fans only make it to 35-60cfm at best, 50 avg. 86cfm is huge and as it ends up, too good to be true. I bought 9 to build an array and after 5 mins on max they get so hot ~110F+ that you can smell the plastic melting/off gassing. Had to turn it off after 7 mins because they made the room smell toxic. Way too much power in a way too cheap case. Definite fire risk. Also PWM was a joke, with a PWM controller I only got 2 levels, max and super weak. UpHere has some good cheap fans, but avoid these entirely. I’m stuck with them, but won’t risk using them again. 86cfm ARGB 120mm for $4 each? Nope—too good to be true.

The media could not be loaded.  While shopping around I tried to find fans that had the highest CFM. These things put out some serious air. Granted they do get a little bit noisy when they're running at 100%, but when they run just normal PWM they are absolutely fantastic.

screws didn’t work for installing them but they look super nice

Had them for a couple weeks and one of the fans leds stopped working.
