## Customer Reviews

### ⭐⭐⭐⭐⭐ Works great!
*by P***2 on August 28, 2025*

Works great. Threw it on a 3d printed bracket and mounted to an external gpu. Keeps the temps nice and low.

### ⭐⭐⭐⭐⭐ Impressed, moves a lot of air.
*by N***K on November 10, 2025*

Moves a lot of air for their size. Quite on low setting. Loud on med-high. Grate for keeping amps or electrics cool for best longevity and proformace!

### ⭐⭐⭐⭐ Controller DOA Fan Worked OKAY 𖣘
*by W***E on June 29, 2025*

PROS: This fan works. Hooked it up directly to USB Power supply and it drew air and will be ready for hot days to help pull hot air out of my computer from outside the enclosure. Comes with a guard to help keep foreign objects from getting caught in the fan. CONS: I ordered the 120MM fan so that I could get a sliding switch controller as I suspected there may be trouble with the button switch controller. Hooking first time using the controller FAN would not work at all. Fan only worked when hooked directly into power supply. Yes I'd buy this again.
