At first I thought to test the Heatkiller IV on the AMD Ryzen CPU, which is really popular recently. However, Ryzen does not need any special cooling and won't overclock higher even on the best water cooling what you could see in our previous reviews.

Recently Skylake-X has appeared in our redaction and it's much more demanding platform so I decided that the real challenge for the Heatkiller IV will be the i9-7900X processor.

Stay with us and on the next pages of this review you will see what I have on my mind.
