One of the potential advantages of liquid cooling is that it achieves the same or better temperatures at lower noise levels than can be obtained from high-end air-cooled coolers. However, Corsair's iCue H115i Elite Capellix is a low-noise all-in-one cooler that replaces one of the best CPU coolers, the H115i RGB Platinum.

Newegg has it marked down to $149.99, $20 below list price, and you can double your discount by mailing in a $20 rebate form Mail in a $20 rebate form and your discount will double. I prefer a straight discount that I don't have to jump through hoops, but it's still worth jumping on this deal since I'd rather pay $129.99 than $169.99.

If you're looking for a quiet liquid cooler. Jeremy reviewed the H115i Elite Capellix last December, and other than some frustration with Corsair's iCue software, it worked really well.

"Once up and running, the H115i runs super quiet at idle. In fact, you would have a hard time detecting it with normal hearing. Even better, the noise level is very well controlled, even in the most extreme performance mode," Jeremy wrote.

He tested the cooler on a 10-core/20-thread Intel Core i9 10900K processor and found "noticeably lower temperatures" than several other AIO coolers tested on the same CPU, including NZXT's Kraken Z63.

In other words, it runs super quiet and does a great job of keeping temperatures down. This is exactly what we look for in a liquid cooler.
