I think Zorg may be right and my mobo does not have the 'Crazy cool' backplate thought Gigabyte and Thermaltake website say i do
If you look at this
it almost suggests that the whole heatpipe solution has to be removed!?
I managed to peak under my mobo (still in case) and cannot see the plate so I think I should be okay, thanks for the help guys i really hope this Ultra 120 extreme delivers
