Bottom Line

For cases where space is tight, this liquid cooler provides plenty of power while keeping a slim profile.

Pros

Gain up to 40% in cooling performance over CPU box coolers with this enhanced design. The 25-millimeter thick radiator provides ample cooling surface area while maintaining a low-profile for cases where space is at a premium.

Cons

At higher speeds, the fan tends to rattle and can be quite noisy at times.

A brand name synonymous with quality computing, this cooling solution is both simple and reliable.

Pros

Simple, powerful, and efficient, this is an actual Intel certified cooling solution. This CPU cooler is not only backed by a 3-year warranty, but also looks fantastic in your case.

Bottom Line

Combining advanced cooling technology with quality hardware, the Rosewill can give you greater control over your case temperature.

Pros

With a microfin slim copper cooling block for better thermal conductivity, and a high-power pump at the radiator, rapid liquid circulation transfers heat quickly from your CPU. You'll also have more control over your fan and pump speed with this model's 4-pin pulse-width modulation.

Cons

May not be sufficient to overclock your machine, and the motherboard connection can be a bit unstable.

If you want to keep your case looking clean and sleek while making sure it is staying cool, this baseline CLC can offer the best of both worlds.

Pros

The base model of the CLC line, this cooler features an interchangeable 120-millimeter fan, elegant hoses, and an intelligent wiring system that eliminates those messy wires, and keeps your gaming case looking clean and sleek.

Cons

Flow Control software has a known conflict with Ryzen processors. Only compatible with Intel sockets.
