I can confirm that the iChill X3 does fit - just. I wouldn't even say it's a difficult install - fairly straightforward I fact. Using a Gigabyte Z97n mobo the power cables are fine as the board isn't very tall and the cooling solution is not quite 2.5 but not 2.0 width either. The shroud over the heatsink and fans just touches the hole in the front panel when fully seated. It's an absolute beast of a card. However, no chance of putting full sized fans in below it, I think. I did a dummy run with a couple of 120mm noiseblockers and it's far too uncomfortable for me to commit to. I may have another go later since I need to take the whole thing apart again anyway. My whole build feels like it's a spring coiled tight. The Dark Rock TF pulls hard on the mobo PCB when done up to what I would consider are normal tensions. The mobo needed forcing into place against the I/O plate. The power cable extension results in bent fins on the CPU cooler, and I can't take out the GPU without busting the retaining clip of the PCIe slot because it's impossible to reach and press when you wish to remove the card. I imagine that touching any part of the setup will result in it flying apart. As for my current problems, I assume that when you initially switch the PC on I should expect the fans on the GPU/CPU/PSU (or at least of one these) to roar into life initially. The fact that it doesn't means I possibly have an issue with the switch/mobo jumper and PSU. perhaps cables not sitting fully in place. I'm going to have a play later - always start with the cables, right?
