Hi, I have mine running at 250, I have a Temp probe in between
the board and heatsync currently its at 54.8 Celsius is this a good temp?
What temps should it run at?
Are you keeping it in the freezer?

Mine are at 41C on the ASIC chip itself (according to my point and shoot laser probe). So I could overclock some more? I am with ppetrovic68, what is a realistic max temp?
Also, I'm thinking of building up a 3D printed cowl to sit on top of the USB hub with a case fan pulling air through the cowl. Anyone done anything similar that I can "borrow" ideas from? I have nearly the same setup as Biodom with the Superbpag 7 port hub connected to a Raspberry Pi. I think it would cool to have two of the Superbpag hubs lined up side by side with a aero cowl leading up to a 80mm case fan.
