An alternative to air cooling cards is water or immersion ones. Due to its use, it is possible to increase repeatedly the density of the card installation as well as reduce the cost of electricity at least four times.

well, I agree with your. that cooling it is very important if our friend above would like to have many hardware mining (RIGs) which much more.

preferably, need to consider the cooling I think the air conditioning is not enough to cover the damage on your RIGs
