Dear Customer,
Thank you for contacting Bitspower.
The Hercules pump doesn't support an alcohol loop.
The alcohol’s high volatility can lead to bubble formation and cavitation,
which may result in impeller damage, increased noise, and reduced pumping efficiency.
Alcohol will damage the seals and may cause the acrylic plate to crack or break.
So we don't advise you to use Alcohol as the coolant.
