I have recently got one MSI 280x twin frozer gaming edition.
The card runs over 80 C with intensity at 12. That is why I am not able to run it at max capacity (I 13).
Is it due to high ambiant temperatures as summers are here (Mumbai);
Any way can I run these cool. I currently have one Asus 270 x and MS! 280x on GA 970 DS3P. Asus runs less than 74 always.
