Boost on the CPU I have set to max at 4.8GHz plus did set an undervolt to keep it cool and quiet without much of performance loss (it can easily get to 5GHz with some BIOS changes but higher temperatures and noise were bothering me more than slight performance loss) !!! Last time when I was doing my yearly re-pasting one of the threads for CPU AIO mounting just snapped and it is kept by 3 screws only. I tried to order a replacement from Corsair but it was not available to buy. I did not see any difference in temperatures so I kept it as is but anyway I am reducing my asking price because of that. !!!
