I have two rigs and issues with fan speeds.
0) 2x HIS IceQ X2 OC R9 390X
1) 1x ASUS DirectCU II R9 270X and 1x Sapphire Dual-X R9 270X
The 390X-rig runs quite stable. But sometimes I notice the temperature is rising above 90°C without a notable increase in fan speed. I sometimes set the fan speed to 50% on both cards to keep the temperature below 80°C, but I think that's not good for the fans to keep them running at high speeds.
The 270X-rig also runs stable, but the temperatures are going crazy. The cards are at temperatures of above 100°C after several minutes of mining. And yet again the fan speeds do not auto-adjust (it seems). I have to set the fan speeds to at least 60% to keep the cards running below 80°C.
I am wondering: Why are the cards not increasing fan speed automatically? 90 or even 100°C as far away from healthy I guess!
Any ideas how to automatically increase fan speeds without manually monitoring the devices all day long?
The rigs are open and well ventilated. It's just the fans not kicking in hard enough. Any way to adjust the auto-settings?
