Yeah, warm and fuzzy, that's how you treat them

Reminds me of my garage in the heyday of GPU mining. Good to know that the S3 doesn't mind these temperatures.
It's indeed nice to know that they hold up well in higher temps but just the same, YMMV considering the assortment of performance variance among the S3s that we have come to know.
I'd like to think that re-torquing the heat sink screws before firing 'em up made a difference. I'd also like to think that setting up my units in V-Air (Vertical Airflow) configuration made a difference. Who knows.
