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)
