Well, I finally figured out why my Coolit Evo cooler for the 4790 was acting so terrible!
I'm really surprised because I'm never that bad at mounting a cooler. I would have remounted sooner, but to do it requires taking apart the whole case, removing the mobo tray and then the mobo since it's a smaller mATX case, and that's just too much work.
Anyway, I replaced the Coolit with an H80i reburb unit that I snagged of the Egg on the cheap, and it looks very good and practically new
So now the Coolit will be moved over to the i3 to replace the stock HSF.
