Nope! Maybe 300 at the most. They pretty much just turn to chracoal and go out with some coals on the top still glowing. Its hard to explain. Iv empited out big hunks of unburn coals that were 10- 12% moisture content when they entered as firewood. The temp seems to drop in a hurry and they go out. I asked that maybe becuase of the fan but was told it wouldnt cause this.
