upHere 120mm Long Life Computer Case Fan Cooling Case Fan for Computer Cases Cooling,5-Pack,12BK3-5

Using 5 of them in a case with a Core i7 4770 and R9 380. Running off of molex (double-stacked), and the system stays impressively cool in a Zalman T7 case. Under full load in Aida64 (GPU+CPU combined) with a cheap $20 stack cooler, the CPU maxed out at 67 degrees and the GPU maxed at 73 degrees even with power limit set to +20% and a substantial overclock. The fans definitely have some noise, and they aren't built to be silent. I have four Noctua SP-120's on a 240mm radiator in my primary gaming rig. But fans are fans, they move air, and they work "fan"-tastic. If you need cheap fans, buy these, period. It's better value than spending $20/fan and you can squeeze a bit more out of your budget. Oh, and they include screws.

In the MB i purchased I have a single header for case fan so i opted for this set that has both 3pin and molex, I daisy chained the fans and connected the last one to the MB headset with it reads the speed of but can throttle all fans simultaneously to adjust for case temperature. I have a RX 570 that on idle was always 50 degrees (ambient temp is 30 degrees) and while light playing would climb to 80+ degrees the CPU itself would sit in the high 40's and under use would reach low 90's after adding 3 fans in the exhaust configuration and 2 fans in intake pointing to the GPU now the temps idle are low 40's and under load, GPU is mid 70's and CPU high 60's. even ramped up fans don't produce much noise but most of the time they sit in the 1k rpm.

I am using three of the five in a build, and I can barely hear the fans spin at all at full speed. I am using the Molex plugs instead of the 3-pin case fan plugs due to the old motherboard having only one case fan plug, and I have no 4 way splitter for these fans (the back fan is a 140mm). It's moving the air quite well too. The price is also good for five fans. Overall I am happy with the purchase.

The 3 pin version of the fans work well and push air but only just enough to well push air… I love these fans but if you decide to buy them get the 4 pin version

I can appreciate that these can be powered both by 3 pins and molex cable which allows options and usage. They are simple but do the job. The noise level isn't anything obnoxious. I'm slowly piecing a Frankinsien computer together so this was a solid bargain for easy airflow.

Buen producto, buenos materiales

These fans are ok, they help air circulation inside of the case, pretty quiet, the way the power cord is made is not the best, but is ok I guess, it does feels cheap as soon as you touch it, looked nice all together on a blackout system.

Nice affordable fans. I installed in a Lian Li A3 case with a B650 style motherboard without issue. They run quiet and I like that they don't have any annoying flashy lights.

Easy install and they all work as indicated.
