Bought this cooler mainly for aesthetics and the fun of PC modding. I'm running an i5 9400 so heat isn't really an issue, the CPU would max out around 70c under full load with the stock cooler. With this AIO fitted and the fans at 50% it now never goes over 56c. The fan speed is important, in my setup, putting the fans to 100% only gives a 1-2c drop in temperature, but a massive increase in noise, in other applications, maybe with beefier CPUs or overclocking, the increase in airflow may be worth it, just not for me.
As a bonus, removing the stock cooler, which just vents into the chassis space, with the AIO venting out the top of the chassis, I saw a 5c drop in my GPU temperature as well.
Installation was straight forward enough, I have a reasonable level of PC building knowledge, but it may be difficult for a beginner.
-Build quality seems good, can't comment on longevity yet, only been installed a month
-Over 10c drop in CPU temperature
-Looks good, RGB on the pump unit and fans
-Molex connector for RGB controller, come on Cooler Master, my PSU doesn't even have a molex connector, a lot don't these days, had to buy a SATA-molex adaptor
-Included fans noisy at 100%, you could easily swap these out and taking into consideration the overall price of the unit, it's only a minor gripe, but may be a factor for some
