I want to upgrade from my i3-3240, to a i5-3470. I have two questions though. My motherboard is ECS H61H2-M6 v1.0 and according to this website: https://www.cpu-upgrade.com/mb-ECS/H61H2-M6(V1.0).html my motherboard supports the cpu but I just want to be sure of it. And the 2nd question is, can I use the stock cooler that came with my i3, or would the i5 get too hot?
