Title says it. I'very been pretty dead set on replacing the cooler on my EVGA 1080ti SC Black with. Kraken G12 and an H55. I would shim it so that I could leave the stock top plate and back plate intact. However, I have seen that you can keep the VRMS plenty cool with just a fan. In due diligence, I've also been researching the Arctic accelero III and IV. I actually had one on a 7970. I think the IV version looks far superior to the III as you don't have to futz with all the heatsinks, but I'm not sure about clearance issues I would have with the backplate and my Silver Arrow cooler. I guess I could use a lower pcie slot. The Rajintek Morpheus II really intrigues me. It looks like, with the right fans, you can get very cool and quiet. I saw a video comparing it to the artic accelero III on a 1080ti, but the guy had a small case where he had to mount the fans as case fans to get it to fit. The accelero showed better VRM and GPU temps by a small margin and was quieter. It seems to me that the Arctic Accelero is the cheapest and quietest option with very good temps, but also looks the lamest. The kraken g12 looks like a top performer and you can carry it forward, but it's probably the loudest and most expensive option. The Rajintek looks pretty cool, but you need expensive fans to make it cool and quiet and it's going to take up the most space. Any of you guys tried more than one of these so that you can compare and contrast?
