I just installed my new i5-3570k proce running the stock H/S and fan. What I noticed was that it is half the height of my old C2D. It almost looks identical with my C2D 775, can I use that instead? How do my temps looks with the current load? I have one intake fan pushing air over my HDs in the front, and two 80mm in the rear.
New CPUs tend to have lower TDP but also less surface area to get their heat out so temperatures end up staying more or less in the same ranges except for IB which has a 5-10C handicap due to using paste instead of solder between the CPU and IHS.
Looks spot on for 100% load and stock cooling. I've heard of the 775 HSF mounting fine on the 1155 but if you aren't looking into aftermarket HSF for your CPU I'd just stick with the one that came with your recent processor!
