5 Best Liquid CPU Cooler For i3-8350k In 2020

Liquid cooling is now one of the best ways that you can keep your PC running at optimal temperatures, even under heavy loads. It’s an amazing technology that’s a whole lot more efficient and reliable than the traditional fan-cooled system, but it does come with a higher price point. But, if you want something that you can rely on, liquid cooling is definitely the way to go, even for lower-end quad-core systems like the i3-8350k.

So if you’re ready to get started in liquid cooling for your processor — specifically the i3-8350k — be sure to follow along with us. We’re diving into the five best liquid CPU cooler available for the processor.

Alphacool Eisbaer 280

Alphacool’s Eisbaer 280 is number five on our list, and is one of the top performers as far as liquid CPU coolers go. With their 280mm model, Alphacool has been able to bring excellent cooling performance to the table while giving you some excellent value for money. This one won’t cost you much more than $130, which is a lot cheaper than most top liquid coolers out there today, especially one’s that are the fan and pump combination.

Alphacool makes it easy to control your Eisbaer 280 without any additional software — all of the functions and features inside of this liquid cooler can be customized and managed straight from the BIOS so that you can adjust cooling performance to your liking — no third-party downloads necessary. The Eisbaer 280 is available in a variety of different sizes — 120mm, 140mm, 240mm, 280mm, 360mm, 420mm. Price does jump the larger you go in radiator size, but the 280mm is probably the most affordable as far as the performance and value for money mixture go. 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 quickly.

Corsair H100I V2

Coming in as number four, we have one that might be familiar to you – the Corsair H100I V2 Corsair is known for its prowess in gaming peripherals, but the company makes some awesome liquid coolers as well, the H100I V2 being one of them. What we really like about this one is just how versatile it is — the H100I V2 is capable of keeping both AM4 and LGA 1151 sockets cool, as well as plenty of legacy sockets. As you might imagine — and would expect from a professional company like Corsair — there is some excellent cooling performance inside, but unlike the Eisbaer, you cannot adjust performance from the BIOS. You’ll have to download Corsair’s own software on your PC — the iCUE software. This allows you to make a number of adjustments, including control over the RGB colors, fan speed, and etc.

Corsair H100I PRO RGB

We love Corsair a lot and their ability to offer some excellent products seemingly all the time, and while the H100I V2 is one of those, the H100 PRO RGB really is an incremental upgrade. This one is for those that want the power and cooling that the H100I V2 can provide, but with all of the extra bells and whistles. You get much of the same cooling performance here, but there’s a lot of light manipulation that you can do with this one. Your primary lighting ability here is on the pump itself — there’s a number of colors that you can customize it with in the iCUE software. Not only that, but you can control individual fan speeds and pump speed from this software as well. If you want, you can even monitor coolant temperatures from the iCUE software.

Now, what we really like about the PRO RGB is the Zero RPM Mode: cooling fans stop entirely when your processor is at a low temperature, eliminating noise from your PC entirely.

Thermaltake 240 Water 3.0

Coming in at number two, we have Thermaltake’s own 240 Water 3.0 liquid cooler. This one was designed for the average user in mind, but you’ll have problem keeping your i3-8350k cool, even under heavy loads. This one is a little cheaper than Thermaltake’s premium Floe Riing Cooler, but that does remove some of the bells and whistles from the premium model, such as the app support and RGB lighting. Still, the core, premium performance is there, providing you with high quality liquid cooling abilities, even under heavy loads. There’s little to no noise in this one, and the built-in governor does a great job at limiting RPMs.

Corsair H115I Pro

And as for our first and favorite contender, we have yet another option from Corsair — the H115I Pro liquid cooler. Like many of the others on our compilation, this one comes in a variety of radiator sizes, but 280mm seems to be the sweet spot. The dual-fan liquid cooler is able to stay quiet, provide excellent fan performance and airflow, and that’s even under heavy loads when you’re doing some gaming or demanding professional work like video editing, programming, etc. This setup does have some RGB lighting customizations available to you, which can all be modified from the Corsair iCUE app.


Here we’ve shown you five of the best liquid CPU coolers that you can get for the i3-8350k. The nice thing about these is that any of these will be able to keep your processor cool under heavy loads, even if you pick up a cheap one. The reliability and peace of mind is just really nice in the higher end models, especially if you plan to have your processor working hard for long periods of time.
