22 degree in the room, but PC in the usual case w/o cooling , may be I have to open it better and do minning w/o cover?
From my experience not so much matters the temperature, but good ventilation. You may have 35C around but with good ventilation you should not have more then 70 degree. So yes, I think it is better to ensure good air flow. At least, you may try.
My 390X Nitro now mine at 310-312 s/s with 68-70C @ 45-55% fan. But environment is around 17.5C. At 22 they still will be 70C but cooler might be at 60-80%. Rigs are open, no cases. If I shut all windows, the temp immediately will rise.
Thank You! I made mistake when put this card for minning in close case!!! Bad ventilation!!!
