Re: is 76c to hot for a rx480 how can i lower sia coin hash rate for cooler performa
wow, are you all noobs here or you just don't care or what? 
for 24/7 card workload you'd want to go below 70°C core definitely otherwise your cards will have reduced card lifetime for sure(graphic cards aren't designed to work 24/7 75+°C)
I'm keeping my cards mining @ 63°C max. If there is any environmental heat rise I downclock my cards to match my targeted temps.
Keep your cards healthy and not too hot and they'll work for a very long time
btw: 76-78°C is way too hot for 24/7 workload, that may be ok with older cards such as 5xxx/6xxx series because of the larger fabrication process, smaller fab process gpus are far less resilient to higher temps and constant temp changes(heat extension)
They are absolutely designed to be run at that temperature for extended periods of time. 80C is perfectly finefor 24/7 card workload you'd want to go below 70°C core definitely otherwise your cards will have reduced card lifetime for sure(graphic cards aren't designed to work 24/7 75+°C)
