COCO AFB0612VHC 6cm 60mm Fan 6015 12V 0.36A Ball Bearing 4-Wire 4pin PWM Air Volume Cooling Fan for Desktop

Works great

Works OK, a bit noisy but since PWM not a severe problem. It would be better in a 60mm X 60mm x 20mm factor.

A little loud past ~3000rpm but the sound is 'not cheap'. No rattling buzzing or annoying noises, just a fan moving at 5500rpm

I am doing a new build using an old HTPC case. I love this old case. I had given it to a friend who gave it to her grandson who then spilled a glass of milk into it. Fried everything. She gave it back to me and I gutted it and washed it in the dishwasher. It looks like new!So, I bought all new cooling fans. The two fans pictured were bought from the same vendor and fulfilled by Amazon. As you can see by the pictures, the fans do not match. As a builder ( I have built hundreds of PC's for friends, family, and work ), I take pride in what my finished build looks like. The labeling on each fan looks identical. But, the fan blades are not the same size. This is going to affect air movement performance. The larger blades can move more air at a slower speed than the fan with the smaller blades. This is going to create an imbalance or weird noise since the fans would have to run at different speeds to move the same amount of air.I'm going to order two more of these fans to see if I can get a matching pair. If not, they will all have to go back.

Not sure if this one because the wires seem very frail. Had another delta fan for years and upon comparing the two, this one seemed...less robust. It worked well enough but I couldn't take a chance due to the case limitations.

Pros-Fast and controllable, speeds were over 6000 RPM according to software- Quiet, unless its at 6000 RPMCons-No mounting screws-the connector for the pins is very short, maybe an inch to two inches long, wouldn't reach my connector on the motherboard so i plugged in elsewhere-Fast enough it cut my finger because i was doing maintenance while the PC was running

It works, I just don't have a real use for the two I purchased yet after I saw how small they actually are.

I specifically bought this fan because of the 60x60x5mm dimensions listed. It's not 5mm thick, it's 15mm. Completely useless.
