Hello, i've just pieced together an Asus p6t deluxe 2 ver 2 with an i7 920 and i've got the stock cooler blues, my last build I used to cooler master v8 with an i7 920 and a rampage II but I wanted to get something that was more functional and less gamer. My search has brought me to thermalright's ultra 120 series. I see that there is a new Extreme 1366 version that has a new fan holder but is that the only physical difference because if not I will just by a true black and buy a 1366 retention bracket. Is there anyone out there that knows what the differences are?
