Review: 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.
Review: Faster speed than the one I am replacing on my Thermal Right Frozen Edge 240mm AIO so I ordered a second one so both fans will match speeds. Never had any issues with their products.
