Lol, yes, it's a proper space heater that 9590, even when pushed to 5GHz my 8350 didn't heat up that much. I think when you have proper case cooling, original 2700x cooler will be good. I had it on mine for a month until I got AM4 kit for CM Nepton 140xl and worked fine even up to 4.2GHz OC on all cores although it was at that time hitting about 75c under full load. BTW, that Nepton is holding CPU to no more than 65c, no matter what.
