Corsair iCUE H150i RGB Pro XT Review

Performance

It’s hardly surprising that the biggest cooler that I’ve had on this enthusiast test-bench is also the coolest. It’s the only 360mm cooler I’ve had on this setup, and it makes light work of the i9-9900K at stock clocks.

Locking the CPU to 5GHz quickly ramped up the heat for most coolers, with the 120mm air-cooled Noctua hitting a whopping 95c in a hurry. However, the TDP capabilities of the H150i are a LOT higher, and that managed to top just 79c. Still hot, but for a 9900K running at the red line, it’s pretty damn impressive.

What I do love about this CPU cooler is that it can stop the fans entirely. That means it gave me NO noise at low load and stock clocks. Not bad at all, of course, they spun up under load but still seemed to idle at a mere 34 dBa.

When I overclocked, the idle mode was still active, which is bloody impressive. However, the noise levels did hit 54 dBa at full load. Now, what’s interesting is that this is competitive with other AIOs I’ve tested, but they only had two fans running, this has three, so it’s more impressive than it seems.
