Bests & Worsts Reviews from Amazon

I purchased this unit in Aug of 2016 and installed it into a fully brand new PC build on an Intel i7 6700K 4GHz processor on an Asus z71 Sabertooth MoBo with Corsair Dominator 16GB (8x2) 3200MHz DRAM, EVGA SuperNOVA 850P2 PSU into a Corsair Vengence C70 series mid tower. A week ago on 3/27 the pump completely failed. I submitted a ticket through Corsair's website and used thier interface to look up the part # for the H100iV2 which it populated with CW-9060009-WW. I choose expedited RMA and had a $120 hold put on my CC so I would get the new replacement cooler ASAP. It arrived today, but it was not the H100i V2. I promptly called Corsair support and was told it was my fault and I'd have to pay to ship both units back and then they'd ship out the replacement v2 unit. Or I could have another $129 hold placed on my CC and they'd ship me the new unit now but I'd still have to pay to ship both units back. Needless to say I'm not happy. I've now been w/o my PC for over a week, and it looks like it will be another week. At this point I'm considering buying a different unit from Amazon, and just selling the replacement unit when it finally arrives to try and cut my losses. I'm extraordinarily disappointed that the first unit failed after just about 7 months and my interaction with Corsair's Customer Service has now put me off of the company entirely. YMMV.
