• Interesting, I have noticed that my USG is very hot but no performance issues (although I haven't been looking). I recently tidied my boiling hot, nest of wires cupboard after my Tivo box kept shutting down due to overheating. Still not amazingly tidy in there though and zero airflow. I have a load of decent, spare PC fans but no way to power them. USB one looks a good idea but I'm loathe to shell out for another one, does it have some form of speed control that you can access?

    All you need is a 12v supply - then you can attach it with screw in 12v barrel connectors, assuming you're not fussed about speed control.

    Most things in that cupboard are a mix of 5v, 12v and 240v.

  • Good point, I'm sure I have a few 12v power supplies knocking around. Realistically though it would just be blowing hot air from one part of the cupboard to another. The real issue is there's no ventilation.
