Review: These are the best computer fans ever seriously! - I built my first PC back in May. I bought a few of these fans and several other fans from four other places to try to figure out which ones would be the best by far buy a longshot for several reasons. These are far away the best computer fans I’ve ever seen barely heard because they don’t make a sound or used. They also come with these little rubber, grommet things that go on the corners. I’m assuming to keep down the noise, but they’re so unnecessary because they’re super quiet really easy to attach is a matter of fact the moment I put one in my hand and kind of flick the blades around I knew they were gonna be good because they were super well balanced. I ended up putting 15 of these in my computer case and shockingly. My Nvidia. GPU fans were louder, and they are barely making any noise at all the sound you’re here is just the wind wooshing out of the back of the computer case. Also, they are extremely powerful. I believe up to 3000 RPM. They knock the temperature down 20°C in about 30 seconds so whenever my CPU or my GPU got to 40° the jump from 50% power to 75% power knocked the temperature down extremely quick. Originally, I just had one of these ones in the back up top and one in the front up top and then some lesser powered ones throughout the inside to avoid getting any negative air pressure worked great once I had returned the other ones I didn’t like and I just got a whole bunch more and I’ve been so happy ever since. I mean, I can’t even believe I’m writing this long review over a computer fan but much like cell phone cases. It’s just funny to me how you can spend $100 on a cell phone case that’s supposed to be the best and it’s just not as good as the $15 one and these fans are really reasonably priced. I definitely think it’s the most fair price for the best quality I could’ve easily spent an extra $27 per fan to get some Noctuas but there would be no point other than just wanting to show off a label and I would like to add that I did buy one Noctua fan was not anywhere near as good. Lastly, I’ve had these since May. I wanted to wait a nice long time to give a nice fair review. All of them work perfectly still have had zero problems. Some of the other fans I had started making noise rattling broke down not these ones oh and I guess really lastly lastly delivery time was really fast sellers awesome so super appreciated. Thank you so much for all your first time PC buyers out there. At least you know you can buy these and it’s one less little bit of stress. you have to worry about do yourself a favor and by at least none of these if you’re getting a high and CPU and GPU at the very least it’ll keep everything nice and cool especially in case your GPU fan stopped working or your cooler fan stopped working. These fans will take care of all of that.
Review: Best fan I’ve ever owned - Cooling enthusiast here. I’ve been a huge fan of thermalrite’s first version of this specific fan for a while now, they are cheap, clean, quiet and move tons of air. Needless to say I was exited to see that they made this version. It’s everything I liked about the original fan with one key improvement, speed. It now can rotate up to 3100 rpms and move an insane amount of air, it still works at the normal speeds too which I recommend, 3100 is loud af and kinda scary but that’s the best part. Thermalrite is really out here making fans for the people. Other companies should take notes. I plan on testing these in a server to see how long they can last at max rpm so this review may change at a later date,but the score will stay the same. These fans are the best.

### ⭐⭐⭐⭐ Fast and loud if not tamed by a good fan curve.
*by C***R on January 14, 2026*

Maybe it is my Corsair CommanderXT and case (Y70) but these fans never reach 3K RPM, I get about 2,600RPM on a radiator on intake. I also tried using a powered fan hub still got the same speeds. The minimum is about 550 RPM and they ramp up quickly with the PWM %. The tone when they become audible (about 800RPM ) is a high pitched motor noise that overcomes the wind noise. With six of them on a 360mm radiator it can be very annoying but move a lot of air. The fans feel heavy for their size and their construction feels sturdy. I liked the inclusion of the rubber corners in white, red, and black.
