Corsair iCue Link H170i | AIO liquid cooler | 3x 140 mm fans | 420 mm radiator | 0-2,000 RPM | $199.99$99.99 at Amazon (save $100) You'll need to have a full-size PC chassis to fit this Corsair AIO liquid cooler inside but with it, you'll be able to keep any CPU's temperature under control.
This deal isn't for everyone. It's not because it's too expensive (it really isn't) or that it's not much of a discount (50% saving).
It's not like it's a poor product, either, as this is a seriously capable CPU cooler. The reason is very simple: Corsair's iCue Link H170i AIO liquid cooler is absolutely massive.
With three 140 mm fans and a 420 mm radiator, it's not going to fit in most PC cases unless it's a particularly roomy full-size chassis.
Given that mid-towers are the most popular size, and they're usually designed to house nothing larger than a 360 mm radiator, this cooler is going to have a limited appeal.
