Earlier reviews of the R9 Fury pointed out a lack of overclocking capability, especially when talking about the High Bandwidth Memory. I found that I was able to squeeze some additional clock speed headroom out of both the Fiji core and the HBM. In my testing I was able to see clock speed increases of over 10%. Pretty stout for a card with supposedly no overclocking headroom. In each case, the R9 Fury delivered improved gaming performance with the clock speed bump. To reach the tuned clock speeds I did have to push more current through the core. Usually this results in a significant bump in the card's thermals. However, the Tripe Dissipation cooling system XFX worked on does a phenomenal job at keeping the components cool. In fact, this has been one of the best cooling solution/GPU combos I have ever tested. XFX's six heat pipe, dual fin array solution just gets it done, and quietly. Even when the IP-5x fan speeds are cranked up, the noise penalty is not severe in any way. Especially when you have the chassis buttoned up.
