I didn't return the 2nd one and bought Arctic Accelero Xtreme IV 280X package for it. And it works so well and runs so cool now. Only 50C at 75% fan settings, the rig outside and +20C weather and crushing numbers full throttle. Not too hard to assembly but of course you will need some basic tweaking skills like holding a screwdriver and patience. Highly recommended if you can afford it or find one cheap.
