Core i9 9900K baseline test

Core i9 9900K Baseline test

Time for the essence of this review. The Corsair H100i RGB PRO XT should be more than enough for the range of CPUs from the Pentium to the Core i7 Hexa-core, or even the Core i9 octa-core (which is used here). We ran the test at the default frequencies, but there should still be some room left for OC. First up is the IDLE temperature, measured when the CPU is doing almost nothing, just waiting for any action by the user.

There are no major differences in this case.

Here, it’s becoming more interesting, and you can see some differences. The ambient temperature was about 22°C, which does affect the cooling performance for sure, but we tested all the previous coolers in similar conditions. You don’t want to have the CPU above 75-80 degrees at default frequencies, otherwise, you can assume that the cooler is surely doing a very poor job. This AIO cooler offers solid performance, and it’s in the upper range of 240 mm LCSs. On the next page, we’ll show you how silent the cooler is.
