These fans work really well !!! they move a ton of air. I put 2 of these on a Tesla P40 and they keep it really cool... of course, they are noisy, but cool = noisy. If your looking for something to move air, choose these ! really impressed

Excellent fan very very powerful. Very high airflow. I run this on a 4S Lipo to cool off my RC motors.

I purchased this fan as a replacement for the one which came with ICY DOCK ToughArmor HDD enclosure. When it comes to airflow, this little guy is an absolute beast. I was controlling it via motherboard and even though it was being run at 5V (motherboard limit), I saw speeds exceeding 13000 RPM so you can imagine the speed at full rated voltage of 12V. Now for the sad part: Even at low speed < 3000 RPM, you can't be in the same room as its distractingly loud (can't even watch a movie). When its running at full speed, its like a jet engine. I had no choice but to return it. My final verdict: As long as noise is not a concern or its installed in a secluded area at home or office, this is a great fan for the price. It will do a great job in removing heat. I can't comment on the reliability and operating - life of this fan especially when it operates at such a high RPM. High RPM does take a toll on the bearing unless they are specifically designed for it.

Moves a ton of air but its very noisy and the blades on the intake side have pointed edges that really "bite" if you accidentally touch it while running. Be very careful while its running.
