How many Mhash/s do you get out of the blue leds?
[/cheap irony]
Hahah! I normally leave the UV cathode off. Had it on for looks.

what temp do they run at? Running mine at 950/386 at around 420Mhash/sec and don't have any temp problems with just air cooling.

The one mining 469 MHash/s is averaging 38°C. The other is at 34°C.
