I hope they weren't using those stupid Nyko intercoolers, those are known to f*ck systems up.
Although I hadn't had any problems with my system, I bought a cooler (don't know if its Nyko) for it just in case.
It worked reallly well and kept my system to only slightly warm at the centre in stead of hot.
But after I installed a shiny black casing, I took apart the cooler to paint it black. After I put it back together I had to loosen one fan because there was a clicking sound. After that I eventually had my system shutdown ocassionally when the loose cooler slipped out too far.
If it clicked in like the power supply plug does it'd be perfect.
