When I did my initial test of this, and the fan was on, I could tell the RPMs on the fan were high and the out put was very significant. Now that I have this thing in use (in 20 degree temps) I'm thinking the fan has just about crapped out.
The pit temp is low, the Guru thinks the fan is pumping at 100%, but the fan is barely turning. . and it doesn't sound good. This thing hasn't been exposed to any moisture, shock or anything that would stress it other than the cold temps.
When I first hooked the thing up outside tonight it was behaving 'normally.' But after about a half hour in, the temp started to drop and that's when I noticed the fan not cranking like I would expect it to.
What I'm seeing doesn't seem right, but since this is my first time out of the gate with this, I don't wanna jump to conclusions. For now I've fully opened up the apeture on the fan. The other thing I noticed is if I don't have the small openings on the daisy wheel almost fully opened. . I lose temp... This can't be good. . .
