Overclockers Club published a review on the XFX R9 380X DD XXX OC
A quote from the article:
When you look at the XFX DNA of the R9 380X DD XXX OC, it's clear that XFX puts together an excellent product. You get constant innovation on the cooling solutions that make up the company's Double Dissipation and Ghost 3.0 cooling systems. Splitting the shroud into two removable covers that can be removed without pulling off the heat sink assembly is an interesting development. What's even more interesting is the ability to remove the fans to clean the heat sink is genius. The 90mm fans use a clip-in mounting system that lets the user pull the fans out and clean the dust bunnies in about 30 seconds flat. That allows the cooling to operate at its best with little maintenance. If you don't have to clean the dust out, well, you are truly lucky. This one feature would be welcome thanks to the dander and dust my dog produces.XFX R9 380X DD XXX OC Review @ OCC
