CPU Cooler: Cooler Master MasterLiquid 360 Atmos II
Motherboard: Asus ROG Crosshair X870E Hero BIOS 1512
Memory: 32GB G.Skill Trident Z5 Neo RGB DDR5-6000
Graphics card: Palit RTX 5080 Gamerock OC 16GB
Power supply: Seasonic Focus GX-1000
SSD: Crucial T700 Gen 5 M.2 NVMe
OS: Windows 11 Pro
Cooling Performance

Cooling Performance Overview
We tested the Cooler Master MasterFrame 600 on an unpleasantly warm 27 degrees C day with high end gaming hardware and it passed the test tolerably well. Our main takeaway is the way the CPU temperature drops significantly as the fan speed ramps up. The fans supplied with the MasterFrame 600 appear to work well so we feel the the case filters are quite restrictive and require higher pressure to work adequately. The downside, as you will see in our video, is that high fan speeds result in high noise levels.
Closing Thoughts
In our video we dwell on the details of the Cooler Master MasterFrame 600 to give you a deeper understanding of the process that has clearly gone into the design of this case. The problem, as we see it, is that the details are fiddly and complicated and we predict you could spend an hour or two working with the Cooler Master build guide if you decide to move the major components around.

On the other hand, if you keep things simple, ignore the various accessories and simply build a regular PC with an AIO cooler in the roof (or perhaps with an air tower on the CPU) we are confident you will be happy with the results. The aluminium panels look very good and the build quality is solid, and while the black finish is a nightmare to video it looks great sat on the test bench.
