I have replaced the Antec 1250 with this new cooler. Core i9 9900k. Antec struggled to keep temperatures outside the 80-100C range and I didn't overclock. My son is a gamer so when I saw these prices I got worried. Once installed (the only reason I put 4 instead of 5 was for the installation and instructions) the performance was amazing. Very low noise level, almost silent. In the stress test, the CPU temperature dropped from 102 °C under full load to 62 °C under full load. My son's gaming temperature went from a mid 80C to 46C most of the time. I have not yet seen more than 62°C during the stress test. It also integrated well with my ASUS ROG motherboard. The lighting effects are quite nice. However, the facility is not very good. The instructions are very bad. I recommend YouTube videos for installation. After watching her, it became a lot easier. However, I've been building systems since the late 80's (yes I'm old) and installing a cooler shouldn't take more than 4 hours.
