Just grabbed a 33watt model and will do some experiments with it, might have to go the water cooling route
The 33watt tec is running great just sitting on the p4 cooler with some tim and no pressure. Its icing up nicely and running around 30 at the heatsink i guess. I ran this for 10mins straight and it seems i should be able to pull this off with the p4 cooler and encloser. This will be great as the encloser will have the mc clear t-thread thermally connected to it and should sit above ambient easy which will mean frost free
Going to use a cold finger Rowland, kindia doing a quick half arsed rip of the centrals 1100d tec cooled camera

I think the cooler boxes aren't bad but unless you have got airflow to the cmos sensor then there wasted alot. Really hoping to get sub z's with just this TEC and some cleaver installation of the cold finger to prevent cooling loss while on its way from the tec to the cmos sensor
