So as the title says I'm looking for some help with keeping my gpu cool. In my case (Silencio 352) currently I have stuffed a 240mm AIO cpu cooler, a Corsair RM750 modular PSU, 2 HDD's, 1 ssd and an ASUS Strix R9 390. From what I can tell the fans on the gpu are pulling up heat from the psu and helping the card overheat when I'm gaming. If I turn the fans up to 100% and keep the side off the case I can play most of my games with out too much trouble...but that's pretty loud so what I'm looking for is a way to either keep the heat of the psu away from the gpu (I've tried one of those pci slot blowers with no real effect) or find a better cooling option for the card itself (which I think is my best bet). I've been looking into the NZXT Kraken G10 and the Corsair HG10 but I don't know which is best for me or even if they'll fit my card so any advice would be greatly appreciated. Also here's a pic of my current setup for reference.
