Mining Equipment Temp Ranges

[pjmis]

Hello, I know mining hardware needs to be in a chilly area due to the heat they put out. But what would be the optimal temp in a room than the machines opitmal temp?

If someone has the hardware running at 50C to 63C with a ac unit blowing into the end where the machine pulls in cold air. Would this be optimal for half a year? A customer is thinking about doing this, but idk :/

50-60c is on the very low end of miner temps. Also, you do not want to dump AC directly into the unit. The s9 will run over 110c chip temps, if your temps are that low you dont need AC, just some ventilation to prevent hot air accumulation.
