Thermalright ultra extreme 120 and evga x58

i bought the thermalright cooler and tried to install it, i must have done sumthing wrong b/c i had to rma my board, it would post after installation. the cooler was extremely difficult to install, the backplate that came with it, all 4 holes wont go all the way in on the motherboard and the mounthing bracket was diffult to keep in place and screw down, id like to know if anybody has installed this cooler what your experiances were with it and what suggestions do you have for me or what i might have done wrong, profosionally installing would cost 60 bucks and id dont wont to pay that if i dont have to.
thanks

no its the socket 1366 edition, it only came wit one backplate

if you want good cooling that doesn't break the bank
Don't stay with traditional air cooling

Get the Corsair H50

Its under $100 and will beat any air cooler while taking less space
