Mining Rigs Ready For Summer, Reduce GDDR6 Memory Temps, newegg GPU price scalping, Longevity

Summer is here and my garage is getting hot. The prices of RX 5700 XT have skyrocketed 400%. I was paying around $400 less then a year ago. If prices stay this crazy I then I need my GPU's to last. I'm will to sacrifice a little hashrate to reduce my GDDR6 temps. I will raise my memory clocks back up in fall. Its not worth destroying a GPU to gain a little extra hash.
