I'm wanting to update to a newer case anyways.
But I am running the Stock Paste that comes on the Corsair H60 I could clean it and add some better paste I believe I have some here somewhere left from my last few builds. I may give it a shot as well.
I ended up adding another fan to my Cooling vent got one on each side pulling from inside the case out to the back. it seemed to help drop a few numbers.
