The Best CPU Cooler for i7 8700k - 2021 Review

Let’s get one thing straight. It doesn’t matter what processor your system uses, the CPU is bound to generate heat during the operation.

But if you’re an enthusiast builder, you want to overclock or run excessive resource-demanding tasks such as gaming, video editing, then the integrated circuits including the CPU, chipset and graphics card must overheat.

If the system is ‘breathing fire,' the odds are that these components will malfunction temporarily, if you’re lucky, or you’ll deal with permanent failure.

While your system may be designed to reduce power consumption and throttle performance when under huge workload, these alone, will, almost all the time, not offer sufficient cooling. Enter the air and liquid cooling.

Air Cooling: In this case, fans are used to cool to the system – one or two CPU fans, graphics card fans as well as case fans. These keep the components chilling even at peak performance.

Liquid Cooling (Water Cooling): A series of tubes filled with a coolant, not to forget a radiator, water blocks, and a couple other components help keep your system operating at the right temperature.

AIO: Because of the success of water cooling, all-in-one (AIO) water cooling solutions have now increased in popularity. They offer better performance and come in a package easier to install and maintain.

If you’re looking to chill your CPU, then you most likely cannot decide if you should get an air cooler or an AIO liquid cooler.

And to make it simple for you to decide, we did our research and reviewed the best CPU coolers that’ll keep your system refreshed.  Then we included a chart for quick comparisons.

Our Top Pick: Noctua NH-D15S D-Type

Its lower fins are recessed on either side of the heatsink, which makes it highly compatible with virtually any Intel and AMD sockets. An off-set asymmetrical layout helps provide superior heatsink performance while still retaining high RAM and PCIe compatibility.
Its PMW NF-A15 premium fan allows automatic speed control. It’s dual-ready meaning you can upgrade to two fans for more airflow at any time using the provided fan clips.
