Follow along below, and we’ll show you the best liquid CPU cooler for the i7 8700K processor. Let’s dive right in.

Alphacool Eisbaer 280

Alphacool has outdone themselves with the Eisbaer 280. This liquid cooling unit for the i7-8700k is at the top of the charts in liquid cooling performance. Not only that, but Alphacool has been able to achieve some of the cheapest prices on the market at this performance level. The CPU cooler will only cost you around $130 or so, which is cheap for something this high-end. A nice thing about the Eisbaer 280 is that all of the functions can be customized straight from the BIOS so that you can adjust cooling performance to your liking. This one is available in a variety of different sizes —¬†120mm, 140mm, 240mm, 280mm, 360mm, 420mm — but no matter what size you get, it all comes with the Solo pump so that you have the right combination for your cooling setup. This one is a little more difficult to setup, but with a little know-how and ability to follow directions, the Eisbaer 280 will be up and running in under an hour.

Corsair H100I V2

Coming up next, we’re looking at a brand that you’ve likely already heard of — Corsair. They make an excellent liquid CPU cooler for the i7-8700k, and that is the H100I V2 liquid cooler. If you do some pretty hefty PC gaming, then the H100I V2 is a cooler that you can rely on to keep your processor at the operating temps they need to be at. It has some excellent cooling performance inside, but unlike the Eisbaer, you cannot adjust performance from the BIOS — instead, you must download the Corsair iCUE software. This allows you to make a number of adjustments, including control over the RGB colors.

Corsair H100I PRO RGB

The third contender on our list is another from Corsair — the H100I Pro RGB cooler. This one is similar to the H100I V2 in a lot of ways, but has a couple of extra customization options. The H100I PRO RGB, as you might imagine, has plenty of LEDs on it. And with the iCUE software, you can control the color that you want emitting from this cooler setup. Not only that, but it has a Zero RPM mode where you can stop fans entirely when your processor is at a low temperature, eliminating noise from your PC entirely. The nice thing about the iCUE software is that you can adjust individual fan speeds, watch coolant temperatures, and adjust pump speeds.

Thermaltake 240 Water 3.0

Coming in as our number two pick, we have the Thermaltake 240 Water 3.0 liquid CPU cooler for the i7-8700k. This is a budget-friendly version of its Floe Riing cooler, which dropped app support and pump RGB lighting to make it more affordable for the average everyday user. Even though those aesthetics have been ditched, it’s still a high-performance liquid cooler with low-noise pollution. The built-in governor does an excellent job limiting fan RPMs, even under load, though you can tune it yourself a little bit. It still has some RGB lighting around the fans themselves to give your Thermaltake a wicked look.

Corsair H115I Pro

First up and our a favorite of ours is another from Corsair — the H115I Pro. It’s available in a variety of radiator sizes, but no matter what you choose, it will do an excellent job at keeping your CPU extremely cool. Corsair has been able to achieve some amazing low-noise performance fans while maximizing their performance. Even at 280mm, these H115I Pro is able to stay quiet, even under heavy loads. As you might imagine, Corsair has equipped this setup with some RGB lighting, but that lighting stays away from the fan rings, which keeps the price a little more achievable.
