Awesome fans, great warranty, quality all around.
December 11, 2017
Really pleased with these fans. I used them to replace the stock fans on my radiator (Corsair H110i GT). They fit great and the cables were just long enough to reach the header extension from the cooler, and if they wouldn't it comes with extensions, which is nice! These fans are at least 50% quieter than the stock fans. They also come with low noise adapters, however if you're using PWM controls, that is pretty redundant, since you can control the fan speeds yourself. The dark brown rubber pieces on the corners are removable if you have fitment issues, but I didn't need to remove them.
They do have less static pressure as the stock fans (about half), which concerned me when I bought them. Luckily, the temperatures are pretty much the same (within +- 3C as before, while running at the same or lower RPM's. Even if I had to increase the RPM's, they are still quieter, so I wouldn't mind having to do that either. I also never ran the stock fans even close to their their highest RPM (2000), since they were too damn loud! I am running a pull configuration so maybe it's why I'm not seeing huge differences, but either way it's completely acceptable when you factor in the quietness and durability of these fans.
Lastly, the warranty on these fans are simply amazing, 6 years! My stock fans started rattling a little after 2 years of usage, and they weren't run 24/7 or at a high RPM either (about 700). I believe that warranties are made to end at around half the expected life of an item, so these should have a guaranteed life of at least 12 hours, however with their own tests (on their website/specs), they claim to have a mean run time of 17 years before failure! It's nice to know I'll have these for a while, and not have to deal with rattling or buying a new one so soon.
