Broken stock heatsink: 55c on idle, 70-85 when loaded.
AC7 Pro: 30c on idle, 40c load.
Received the items today, AC7 cooler was open already and didn't receive the paste I ordered.
Had trouble getting in the pins, actually broke two of them getting them in bit annoyed at how they're made, so I have to lay my case so the motherboard is on the ground so it doesn't fall off again. I can forsee trouble in the future when I move it.
But yep, for now it's working with 2/4 pins in..not much else I can do.
