Harp Miner is a main DLC (direct liquid cooling) mining rig that provides ultimate safety and High Hash Rate Power. Harp Miner has been designed specifically to be fault tolerant and to eliminate potential risks associated with liquid cooling. Harp Miner offers all the well-known benefits of liquid cooling without the cost, complexity and risk. The coolant is delivered to the ASIC and manifolds under negative pressure on both the supply and return so coolant cannot leak out; only air can leak into the system. Harp Miner can be placed or used anywhere, such us Home/Office/Datacenter/etc.
