Purchased back in March of 2017 I've used this CPU for maybe two or three years before I made an upgrade and rotated it into a friends system. Since then it has pretty much been in daily use by them as well. Both systems had AIO water cooling setups. I tried to mess with overclocking a few times when I initially got it but couldn't get the hang of it and just switched it back into default settings.
Intel Core i5-6600K 4C/4T (USED) (NO COOLER)
