Well I installed mine when I got home and what a pain in the ass. Horrible system which I hope I will be able to get a full refund from overclockers. Went in with a slight issue but then when booting loud clunking noise. I went to remove to start the whole process again and that's when things went wrong. Trying to disconnect the fan control cable and the pins came out but the header remained in the cool block. Finally got that out with some tweezers but all the pins had bent underneath. Then removed it from the mobo and one of the screws snapped off.
Absolute bloody nightmare as was not impressed. Very poor build quality I think. Never had any issues with any other products in my machine. Hopefully I will be able to get a refund and reinvest the money in a tower air cooler and low profile ram from overclockers of course.
