Best Liquid Coolers for i9 9900k

Best Liquid Coolers for i9 9900k – So we’ve shown you twelve of the best liquid CPU coolers available for the i9-9900k. Any one of these liquid coolers will do an excellent job at keeping your processor as cool as a cucumber. However, no matter which one you go with, you’ll want to make sure that you’re snagging a larger radiator size — 280mm might not cut it under heavy loads for long periods, which is essential to keep in mind when doing any sort of overclocking.

1.Enermax Liqmax III 240

Pros & Cons

Let me explain to you what happened. Back in 2018/2019 people started noticing performance issues with their LIQTECH coolers, especially the TR4 Threadipper ones all of the sudden started to behave weird. Once opening up the cooing block it became obvious there was an issue with clotted mass piling up. Typically this is the effect of using the wrong coolant in combination with LCS units that have a mix of copper and aluminum, which is bound to corrode if you do not use a matching coolant. It became a bit of a mess, literally.

The story exploded (rightfully so) in the media. That however did dent the reputation of Enermax. They came back with an RMA program and released revision II of their product series, the problem had been solved. However, once you get stigmatized, it’ll haunt you forever as for liquid cooling kits you need to be able to trust their faultless operation mindlessly. We haven’t heard of any recent issues for a year or so now. And recently Enermax increased warranty for their LCS units towards 5 years in the USA, with the EU to follow soon.

For that sole reason alone we wanted to test some Enermax coolers again, as yes everybody does deserve a second chance and basically to see where they are in 2021 with their products. The problems we’re quite confident are solved, but the question remains how good their products really are in cooling performance and acoustics, as to date you’ll have seen very few reviews of the product we tested today for example.  Why is that important?

2.Cooler Master MasterLiquid ML240L

Pros & Cons

In today’s review Kent explores this new cooler, struggles with an RGB aversion I just invented to add drama to the review, and takes us down the insidious path to liquid cooling. I for one am curious to see the changes Cooler Master has made with this, having reviewed a 240mm MasterLiquid model myself in the past.

Cooler Master’s MasterLiquid ML240L V2 RGB is an update to the existing 240 mm ML240L liquid CPU cooler that, along with its 120 mm counterpart the ML120L V2, offer design changes intended to increase performance and longevity.


Pros & Cons

The ID Cooling Auraflow X 240 offers AIO liquid cooling for the masses with its dual 120mm radiator, RGB lighting and a pocketbook-friendly  price tag. Unlike the majority of its competitors, the Auraflow X 240 offers AMD Threadripper support in addition to the usual Intel 115x/ 2066/2011 LGAs and AMD AM/FM sockets, making it a versatile 240mm liquid cooler for nearly every current CPU available today.

However, while the ID Cooling Auraflow X 240 does get you expected features like PWM control and RGB lighting for both the fans and pump, dreams of visual brilliance and fingertip hue management are dashed with muted luminosity and lack of desktop software control. The overall performance of the Auraflow X 240 also lags behind its  240mm AIO peers, making the lower unit price most attractive to those wanting to get into the liquid cooling lifestyle cheaply, where the best performance isn’t required.

4.NZXT Kraken X63

Pros & Cons

The software allows you to program, customize and monitor this all-in-one liquid cooling solution for your processor. Armed with two 140 mm PWM fans and a nice 280 mm radiator the performance should be really good, and with the CAM software you can monitor temperatures, adjust pump performance and customize LED lighting directly from your desktop. You know, in the world of CPU coolers nothing ever stops developing. These days you can pick a hundred different heat-pipe based coolers, where many are shaped, formed and priced the same.

The better heatpipe based coolers are good though. Next in line are LCS systems (liquid cooling), the entry-level products are affordable, easy to install pre-fab liquid cooling kits. We’ve seen and tested many of them as Corsair, Asetek, Cooler Master and yes NZXT and so on all have interesting kits.

The product we test in specific is the Kraken X63, it has an updated visual design and allows only to control the pump, but not fans. Next to that what’s interesting is that this product is based on a 280 mm radiator which gives it quite a bit of cooling surface area.

It is a cooler series that is easy on the eyes and comes with relatively tool-free installation. Next to some very good performance, the product is compatible with NZXT CAM software. You hook up the LCS unit towards a USB port and then the software allows you to program, customize and monitor this easy to install liquid cooling solution.
