Corsair ML140 Pro LED, White, 140mm Premium Magnetic Levitation Cooling Fan

It is night and day! I've had the H115i for about 6 months now and though the performance has been great, the fans that came with the AIO cooler were a nightmare. I had to make my own custom fan curve because even the quiet setting through Corsair Link was loud. I never had it on performance or balanced. If I did, it sounded like a jet engine. Not only that but I think my fans may have been defective because there was an awful static noise that I wasn't sure if it was the radiator itself or the fans but since installing these new fans I do not hear it anymore. I just put in two new ML140's and it's whisper quiet and I have it on balanced. I find the sound difference between balanced and quiet to be about the same. I've also noticed a slight temp drop of about 2 degrees celsius. The LED illumination is a nice touch. From my angle, I don't see it that often but I may pick up another fan for the rear exhaust so that I can see them. I picked up the white as I find it goes well with any color from my case LED's. Overall, I am very happy with the purchase.

Incredible fans! Easy to install, had no issues with the screws they came with as some had reported (used my drill at the lowest setting). They look fantastic and can’t be heard at all when running @ around 550 RPM. I haven’t had the need to run them any faster due to the temps I’m seeing even on full load. I am running a 4790k (currently not overclocked but typically @ 4.8 GHZ), GTX970, with a Kraken X61 AIO Cooler. These fans are set up with three as intake on front of my Fractal Design Define S case with two set up as exhaust pushing air through the top mounted radiator. Attached are pictures of the temps I’m running and I’m easily seeing about 15-20 degree difference from replacing the stock case fans. Would remove a star as I think these could be just a couple of bucks cheaper but still great value for the money! Not sure why I can’t upload pics from my phone but as soon as I figure out why, I’ll show the fans installed, the temps I’m seeing, and the NZXT software showing the fan RPM.

These suckers can move more air than any other fan I've ever seen. If you let the rpm go they also get louder than any other 140mm fans.They cost a lot, but they are well worth it unless you can spare the LED's. The non-LED ones are bought in packs and far cheaper. The white is closer to white than any other LED fan I've seen, but if you're planning to light a case with them, they are a bit dim for that, especially at lower rpm's. These are great because they have the capability of ramping up to super tornado, but they move tons of air under 50% speed. The ML series are very good on airflow, and decent on static pressure. When running at lower speeds (1200rpm or lower) they are near silent. Other fans I've noticed have a whine to them at that same rpm that these don't.

I finally received the order, I think the mail was the problem. The product arrived in good shape and it performs great as well. I would buy again from seller if I need another one. I would highly recommend seller and product. Great customer service and sales.
