Fractal design Celsius s24 vs Cryorig a40 vs corsair h100i v2

Solution
if you want to take it to the max with sane voltage and only play games, any 150w TDP and above rated cooler will do the job.
dark rock 3 and NH-U14s will do the job very well.
If you want absolutelly the lowest temps, you will have to delid the CPU to replace the stock thermal sh*t under IHS which is the bottleneck in heat transfer from CPU to any cooler.
