Nice daily cpu, the 9900k I was considering for daily needs 1.25v for 5.0g and not even sure thats R20 stable

Yes, lovely chip. However, keep in mine dude, this was done with the rad placed in the open window, with 5-8c outside temp. Max load temp after an R15 run was 56C. My daily settings are 5.1@1.35V LLC5 set vcore in Apex XI.
