I installed this pump in a 4 year old DangerDen WaterBox with approximately $2k worth of kit in it. I simply wanted to replace a noisy pump. It worked fine for about 3 months and then suddenly died bring down dual graphics cards, processor, mother board and probably everything else. I am throwing the whole thing in the garbage today. I promise never to purchase anything EK sells again. Most likely I will never build another liquid system again as well. Thanks EK!
