S7 (or S9?) - Higher Hashing when Hot?

I know it seems odd, but these mining chips do like to run a little warm. I ahve found that if I let the board temps get under 60c on the S7s they actually start to become unstable and crash a lot more than expected. Avalon 6 miners are the same way, under 60c and they see a noticable hash rate drop. I have personally found with the s7 that the sweet spot is 65-70c.

The S7's like being hot boxes.
As UK temps are falling I'm lowering fan speeds in my mine = warmer miners = more stable hash rate.

I just wanted to get your thoughts... I have a few S7s and typically I'll have the fans at 30% for the reduced noise (around 2600 RPM) and the temps are usually around 60 - but I recently changed a few of them to 20% (1920 RPM) and the temps have climbed a bit to 70. BUT, they seem to be hashing higher by a few hundred GH than they used to. Is that expected?
