I use the Eiswolf GPX Pro to cool my Zotac GTX 1080ti. It rarely gets over 50 degrees under extended periods of gaming at 4k. I was really hoping to get an EK GPU block for it, but they don't make one. I'm glad I discovered Alphacool. The design is a bit different in concept to EK. The water doesn't really circulate throughout the GPU block. Since the pump is on the GPU block, the water only directly cools the processor of the GPU and passively cools the rest of the block which acts as a giant heat sink. Still very effective. It took a long time for me install the waterblock on the GPU, however. Thermal pads need to placed on the front and back of the PCB. It took me hours to meticulously line up all the thermal pads that had to be placed on the PCB. In the end, it was well worth it. Dropped temps by over 30 degrees Celcius. I would expect similar cooling capability with the RTX series.
