ASIC S21 Hyd 335T Review In this video, Sergey, the founder of World of Mining, will test the ASIC S21 Hyd 335T, talk about problems when starting this ASIC and the intricacies of setting it up. You will learn how to use this ASIC in a home heating system, what solutions there are for cooling ASICs in a closed circuit (cooling towers, etc.). Why can ASICs of the 21st series overheat, and how can the VNISH firmware help detect a malfunction? We will show the results of autotuning on the firmware and the real power consumption of the S21 hyd in overclocking. And, of course, according to our tradition, we will look at the table of profitability of bitcoin mining, determine the payback period of the ASIC S21 hyd 335T in factory mode and in overclocking. And you will also find out what surprise we are preparing for all S21 Hyd users!
