Just upgraded to a 1080ti. I mined on this guy for about 2-3 full weeks last month and it never broke a sweat (I Have 2x480mm radiators). Garlic Hash was 370-380ish average. I purchased it new and kind got out of gaming so it had a TON of idle time. The nickle plated water-block was purchased used/almost new. I replaced all the thermal pads with Fujipoly Extreme (like $30 worth of high end thermal pads) so I would suggest not removing the block since it's typically best to replace the pads when you do (I mean go for it if you want to, but yea good thermal pads are not cheap). Card is dual bios and the secondary bios is flashed with stilt's mining bios (you can reflash to whatever you want) When I removed it and cleaned the loop everything looked excellent from everything I could see visually (I used distilled and PT nuke). EK Back Plate is attached and included (Sorry forgot to take a picture). $275 and includes the original heat-sink too (like new!).
