Best AIO Cooler For i9-9900K


The i9 9900K runs pretty hot, and in order to cool it down, we need to get something that is actually good enough with the cooling performance. Thankfully, Thermaltake has just the right solution for those who are looking to have some cooling.

Despite running into some issues, the good thing about ThermalTake is that they have been consistent with their products for some time now. Wherein, they have released some pretty some pretty great coolers in the market, and they are only getting better as the time goes on.

Today, we look at their Thermaltake WATER 3.0 Dual Riing AIO, one of the best AIO coolers that we have used and it is actually pretty capable when it comes to cooling the infamous i9 9900K. But is the cooler actually wroth it or you are just paying extra for nothing? Let’s find out.

First things first, the cooler itself is really easy to install. The installation process hardly took me a minute, however, your mileage may vary based on how experienced you are with such situations. One thing that I would like to point out here is that you should be really careful when it comes to the case support as not all cases support all radiators.

The cooler can easily handled CPUs that run hot, and even provide them with a pretty substantial overclocking headroom. Since we are talking about the Core i9 9900K here, you really do not have to worry about any performance degradations, or thermal issues that might come in the way.

Another really good thing about this cooler is that you can adjust the fans as per your requirements and you will not have an issues that might come in the way. Last but not the least, the cooler comes with three Thermaltake RGB Riing fans out of the box, so for anyone who want to have a good cooling experience, this is certainly the way to go if you are looking for good performance.

On the contrary, there are a few things that we did not think are up to the par. For starters, while the 360mm radiator is actually really good when it comes to performance, but it gets limited by the overall performance of the pump itself. Another thing that I do not like is the design of the waterblock, which happens to be a lot more convoluted than we would like in the first place.

Overall, the Thermaltake WATER 3.0 Dual Riing AIO is definitely a very, very capable water cooler, and the best part is that it does not even cost a lot of money. You can actually buy this water cooler without any issues that might come in the way. It will give you a great performance overall.


  • Easy to install.
  • Provides the extra overclocking headroom.
  • The PWM fans can be adjusted without any issues.
  • The RGB lighting on the fans look really good.


  • The pump limits the overall performance of the larger radiator.
  • The waterblock design is poorly executed.
