If liquid in hydro-cooling miners is not completely drained during storage and transportation, it will cause the following impacts.
If there is no corrosion inhibitor: excessive pressure inside hydro-cooling plates may cause the hydro-cooling plates to bulge, thereby damaging the hydro-cooling plates and hashboard.
If the corrosion inhibitor recommended by WhatsMiner is added, there is usually no obvious problem within one week, but the above-mentioned damage risk may still occur beyond this period.
