Specs are great on paper, but what worries me is what happens six months down the line when these miners are running non-stop. Some brands seem to need constant fan replacements, others get clogged with dust faster. I don’t want to buy something that looks good now but becomes a maintenance nightmare. For those running SHA-256 hardware, which models have actually held up the best long term?

I’ve been running Bitmain, MicroBT, and AxionMiner units, and there are real differences once you put them through months of 24/7 load. Bitmain is efficient but I had to replace multiple fans within six months. MicroBT’s WhatsMiner M63S++ was a tank, running steady but generating a lot of heat, so you’ll need good ventilation. AxionMiner performed surprisingly well: fans lasted longer, hashrate stayed consistent at 800 TH/s, and parts were easier to source compared to some proprietary components. A detailed comparison I read put Bitmain at the top for efficiency, MicroBT for stability, and AxionMiner for value. If you want a SHA-256 ASIC miner https://www.digitaljournal.com/pr/ne...777142536.html that won’t give you constant headaches, I’d lean MicroBT for reliability, while AxionMiner is the best choice if you’re chasing hashrate per dollar.
