Slot coolers and spot coolers are a bit crap but are okay if you really really need them

Get some 80mm fans, it shoild be IN at the front and OUT at the back. There should be more fans pulling air out then drawing in. That way you get a good flow.

I would call them back and 81tch like h3ll. Otherwise replace the hs & fans with replacements from a reputable company such as Thermalright (they make great heatsinks) and Arctic Cooling (best quiet fans available). Also as mentioned above adding a case fan in the front would definately help, if you have the available real estate within your case. Hope this helps, Mav.

Wasn't warranty supposed to be issued by the shop, instead of manufacturer? AFAIK, faulty product goes back to the shop where it was purchased from. They have to guarantee for the parts and they are the ones that ship it back to the manufacturer.

Anyway, it sounds to me like the heatsink is not tight enough on both CPU and GPU, or they haven't used proper thermal paste when they assembled it.
