A heatwave in Scotland?  Huh?



You'd think they could design these cards properly.  That's a triple fan R9 280X in free air, the air being a sweltering (for Scotland) 25C.  Don't they sell these things in California?

likely poor thermal paste application.

Maybe, I thought I'd redone most of them. Apparently it wears out with time and I think they're 10-12 years old.

Those ones don't seem to have adjustable temperature limits, it drops to half clock about 98C, then back to full at 78C. Rather crude.

My newer Nano varies the clock by tiny amounts to keep it exactly 85C, and I can change the 85.

It couldn't possibly because you have 3 or gpu's in that machine and are pushing the envelope ALOT for what that card was originally designed for, sure the MB can handle it but it's mean the card was designed to bring in hot air from the other gpu's and then shove it back out to them etc etc. A nice fan blowing into the open side might drop the temps alot.

The cards are not on the motherboard, they're on risers, and are sat seperately on the shelf. They don't suck in each other's air, and there's a massive twin fan in front of the window a metre and a half away that blows fresh air over the computers when the room temp gets to 25C.

I'm not pushing the card any harder than when playing a computer game, which is what they're made for. Games use them just as much.

Ahh I see, then never mind.
