140 mm

Pros: Works, not noisy, installed as exhaust on the rear panel of the case

I had to wait a while for delivery, of course. But everything arrived safe and sound. I'm waiting for three more identical 140 mm fans. Everything was packaged perfectly. Thank you.

Pros: Excellent airflow, very low sound leakage Comment: This fan really blows hard, noticeably stronger than other fans I've tried. Up to about 60-70% speed (rough estimate) you can't hear it at all. Above that it becomes audible, but it's more the sound of the airflow than the motor itself (though in games you still won't hear it over the speakers anyway). I installed it as exhaust on the top rear panel, and it dropped CPU temps nicely, since the single fan on the back wall wasn't cutting it. Without it the CPU would heat up to 85°, and with it the temps dropped sharply to just over 70°.

Pros: Name Cons: Production China makes audible noise at 800-900 rpm. There are the same ones made in Thailand, those are silent! Comment: People complain about the noise on the China version — those who have the Thailand one and can compare say Thailand is quieter. I swapped the fans for Arctic ones and ended up trading one piece of junk for another.

Pros: This thing is a brontosaurus, I've never seen such a huge fan!))) It's completely silent, pulls with enough power for me. Comes with both a USB adapter and an extension cord right in the box, used both and it was enough to get started, which is great The packaging is like I bought a graphics card, not a fan) pretty cool of course
