First on our list is the Noctua NH-D15, if you do some research on CPU coolers, you will find out that Noctua makes the best air coolers and CPU coolers in the whole PC parts market.

You will be able to overclock your system without any problems, and the cooler will keep the temps cool.

For the ones of you that don’t really want to spend a lot of money, and still get some cooling performance the Cryorig H5 Ultimate is one of the best budget options out there. It comes at $50, and for that price, it delivers a significant performance boost. One user on Reddit reported amazingly low temperatures using the H5 ultimate with his i7-9700K. He stated that he experienced incredibly low temps. At the same time, his pc was idle, and when he was gaming on a 5GHz overclock with 1.3V, he reported temps at mid-fifties and low sixties. Despite the fact that this CPU has a relatively low price, it seems to be able to tame the beast that the i7 9700K is, both at idle and under load.

AIO Cooler


When we’re talking AIO coolers for 9700K, the best thing to do is to go with any well-known brand. All of them are using Asetek components. But you still get some AIO coolers that perform marginally better than others. And, other things also play a big role in your choice. Aesthetics, price range, and reliability are just some of the more important traits when it comes to AIOs. The size of the radiator is another thing to consider and if it fits inside your PC case. Mainly, there are 3 mainstream sizes 120mm, 240mm, and 360mm.

So, if you’re in the market for the best CPU cooler for i7 9700k and want to go with an AIO, we would recommend the Corsair H150i Pro. According to the reviews and tests we did, this is one of the best performing AIOs for the price. For this price, you get the best build quality, a large radiator, and amazing thermal performance as well. The H150i Pro offers up a performance similar to the Kraken X72, which is $40 more expensive than the Corsair H150i Pro. And, in my opinion, the software that Corsair offers is much better than the one that comes from NZXT.

Compared to an air cooler, the H150i Pro is not cheap at all, but when you compare it to other AIO coolers, it is one of the cheaper options out there.

If you happen to be building an ITX build, then you should know that your internal space is pretty limited. This means that you won’t be able to cram bigger components into your case. So, you have to be careful with the components you put inside your system and their size as well. This is the case with CPU coolers as well. This means that you are extremely limited with options that you can put inside your ITX build. The most important thing to do when you’re building an ITX build with the 9700K inside is to choose wisely when it comes to cooling performance.

Because of the limited space, the CPU cooler plays a much bigger role in thermals and performance. The top performer in this category that we would recommend you is the Noctua NH-L9i. This amazing low profile cooler sets the bar for the competition. It offers amazing thermal performance, which is surprising with its small size.
