So my setup is two reference xfx 7970s stock cooling. The primary card is the higher card on the motherboard. At idle with default CCC fan settings, the primamy card holds around 63-66C while the secondary is 41ish C. I'm waiting on my waterblocks to come in later this week but in the meantime this is where i stand with a few questions. Is an idle temp of 63-66 bad for the cards? Secondly, using afterburner I adjusted the fan controls and it seems the card will hold 50C at 49% fan vs 63-66 @ 30% fan. Is the wear on the fan worth the gains in idle temps? Or am i worrying about something that i dont need to be? Ambient room temp is probably around 75-80F though it does seem to get hot in the room when i start gaming. I also dont like the card getting warmer then 80C does that justify cranking the fan speed up to 100% to keep it below?
