 So on the right hand side here you're going to see an LGA 1156 motherboard. This is the old P7P55DE Premium. So this is a Linfield socket or it's a Core i3, Core i5, Core i7, whatever you want to call it. This is an LGA 1156 motherboard with LGA 1156 mounting holes and an LGA 1156 keep out zone. So the keep out zone is what Intel specifies as the minimum amount of space around the socket where there can't be anything there. Alright on my left side I have a brand new LGA 1155 motherboard. So this is with an 1155 socket. It supports the new Core i series 2 chips. So that is if you have a Core i7 2600K that 2 means generation 2. So LGA 1155 despite having fewer pins than 1156 is actually an upgraded platform. Now normally when Intel upgrades their platform and they change the socket like when we saw 1366 to 1156 they actually change the spacing of the mounting holes. However the good news is that if you are shopping for a new 1155 system, you're buying a motherboard, you're buying a CPU and you're trying to figure out if you need to upgrade your cooler, I have some really good news for you. This is an LGA 1156 cooler and this is me putting it on an LGA 1155 motherboard. Just like that. The hole spacing, whoops look at that, random. The hole spacing as you can see is exactly the same. The stock cooler uses the same plastic push pins as LGA 1156 and we even have the same hold down mechanism and the same backplate. I'm going to flip the board over again. And the same black backplate that we found on LGA 1156. So you'll actually see if I flip this over. There you go. These are using exactly the same hardware on the back of the board so there are no changes and the TDPs, that is the thermal output of the processors on both platforms are actually very similar. So if you have one that's rated for a high end 1156 chip, odds are 100% that it's going to work just fine with a high end 1155 chip. So don't fear, you do not have to upgrade your cooler.
