I've had the NOCTUA NC-U6 which is pretty similar to the thermalright.

This has mounted on nb fine with a thermalright ultra 120 & a zalman 9500 AT. U can't mount is on the sb if u have a 2 slot gfx card, the exhaust slot blocks the sb.

currently i'm running with Zalman ZM-NB32K North Bridge

needs a bit of modding


but works a treat


luck
