I installed my two R9 290 Tri-X today, and one of my cards are running hot. I ran Unigine Heaven 4.0 on Ultra, extreme and 8XAA and GPU1 was 88C and my other card was around 66-70C. Custom fan curve with MSI Afterburner so the fan where at 70-80%. I have around 2CM between the cards like i had with my 6950CF and there was no problems. Do you guys know what the problem is and how do i solve it.
