Well, it's been a fun and exciting weekend, but the PC is finally back together and working nicely. My MX100 is in place and has my data on it, another 2TB drive is now RAIDed with my original to give me 4TB of games storage, and....
My Accelero Hybrid II-120 coolers are now both attached to my 290's.
PC booted up after being hacked about, which is nice, and sits at about 40C idle on GPU1 (I have ULPS enabled, so the second GPU shuts down, but because of the way the cooler works, the pump still runs but the rad's fan doesn't). So far I haven't run many games as it hasn't been back together long, but what I have run:
Sniper Elite V2 - 61C GPU1 core, 70C GPU1 VRM1, 66C GPU1 VRM2 ; 67C GPU2 Core, 73C GPU2 VRM1, 68C GPU2 VRM2
I also played Just Cause 2 for an hour (LOVE that game!) and my cores stayed under 70C, with my VRMs staying under 80.
Ran Heaven bench for a while, and that stabilised with cores in the early 60s and VRMs around 70. Just run Sleeping Dogs bench a few times and I'm getting similar temperatures to Heaven. Everything's run at 5760x1080 with (generally) maximum settings.
Fitting the coolers was actually fairly easy, instructions were thorough and clear. The hardest part was finding space in my case for the two radiators/fans. One fitted where I planned, but the other wouldn't because the radiator fouled on parts of the case and didn't match up with the holes, so that's in position "Plan B".
Because the heatsink fits on the rear of the cards, I was expecting to have to move my sound card from slot 1 (my GPUs are in slot 2 and 5) but I hadn't anticipated it would extend slightly beyond 1 slot wide and actually fouled my Silver Arrow.

End result, I'm actually using my stock Intel cooler (the shame!) and have a Phanteks PH-TC12DX on order. Once I've got that and put my overclock back on, I'll get some proper runs and temperatures if people are interested. The heatsink being on the rear is also the reason GPU2 has higher temperatures than GPU1 - it's the cooling for GPU2 that is sandwiched between the two cards.
Apologies for the lack of pictures at the moment, they'll have to wait until I'm at the PC in daylight (and the Intel cooler is back in it's box!). All I will say is there's a lot of pipes, power cables and stuff - it ain't pretty but it's effective and, best of all, much, much, much quieter than my pair of stock coolers!
Apologies for the post and run, but I'm off to bed people as I've got an early start and I'm shattered. Good night y'all.
