I installed this in my NZXT H1 v1 after the stock liquid coolers pump died. With this cooler my temps are way better (on 5600x) and the pc is much more quiet.
Really Impressed.

I am asking a lot of it to keep a 13600K cool, but under regular use and gaming, it does the job well. Prolonged synthetic benchmarks will trigger thermal throttling,
but with some undervolting and power optimizations, it can work decently. Going to try a 25mm fan or 30mm to squeeze some extra cooling out of it.
Recommended as long as you aren't trying to cool anything crazy.

an Excellent cooler for a AMD Ryzen 5 1600. with stock cooler was getting around 71 to 85 celcius under heavy workload for a day.

with the IS-67 it cooled down to under 53 celcius under heavy workload for a day.

in these heavy workloads that last a day, i utilize 7 of the 12 threads and stays under 53 celcius.
