C1 arrived in a record time. Miner is ok, but the cooling kit is the worst thing i have ever seen. The water pump leaked on the first power up and died after 1 minute work, wiring for the fans is bad soldered and the wires are so thin, tubes for the radiators soften if the miner has temperature over 40C. They should take care about this. Syscool should raise the price for 5-10 usd and sell quality not quantity ! ! ! Next purchase will be only miner. I dont need crap
Only bad thing about this miner is the cooling kit. I replaced my defective fans (the ones Bitmain wouldn't honor with an RMA on a brand new C1) with a high quality high CFM, but quiet fan and is keeping my temps down 2 degrees across the board.
I had one broken fan - out of the box.
