Ha I like that light Brent. If your running a 12706 TEC you should be able to go closer to zero from that ambient, depending on which version your using; there seem to be different load rates on various 12706 TECs depending on suppliers. I noticed some way below in this thread that you said it is a 50W version (I think). How many amps were you applying and how?
If it is running optimally and well matched to the heat sink and fan you should not notice much heat at all on the base of the heat sink as it would be being extracted as fast as it arrived and not allowed to build up.
I recall that Rowland had developed a fan/heatsink sizing theory to match TEC capability to optimal heat extraction equipment; I believe it was along the lines of needing to double the watts of the heatsink fan combo from the TEC wattage. In other words, a 50W TEC would need a 100W heatsink/fan combo.
I believe your fan is too small, you could try putting your fan on top of the heatsink and use it to pull air through and out.
