So my Bykski waterblock arrived from Taiwan this morning. Wow lovely bit of kit, weighs a tonne but no instructions and little info on the internet. Couldn't figure how to make it work with the original backplate but after lots of head scratching I got there in the end. All installed and I'm a very happy boy. Was worried my EKWB 60mm 240 rad wouldn't cope with GPU and CPU. Seems fine though. Running Time Spy Extreme and Fire Strike Extreme temps don't go above 51c on the GPU and fans on rad are hardly spinning up, card is OC'd to 2025mhz on core and 6210mhz on memory. Happy days!
