Incubating temp question

[BHReptiles]

Yup, that is the block charger. You can buy one at Wal-mart for like 6 bucks in the cell phone area. The fan comes with a metal bracket to stand it up on your desk I took that off so I can lay it down on my heat tape. I have my fan blowing down on the heat tape so I had to move the speed control to the other side of the fan housing. I set the fan speed to the lowest possible setting and it runs all the time (not plugged into thermostat).

I just wanted to make sure that was what you meant. I think I have a couple of these laying around so I don't imagine I'll need to buy one.

Also, I double checked temps after putting the thermostat probe into a dummy box. All boxes are holding around 89.4* (according to all three thermometers plus the one or two that are not in egg boxes but in the incubator itself!). However, when I go to use my temp gun, it's reading a little over 91* in each box (but it's the same in all boxes). Should I drop the herpstat down a little more to accommodate for this difference? I have it set at 89.5*. I've also purchased a new fan (like Joe suggested) so once it gets here, I'll remodel my incubator and insert the new fan.

Any other helpful tips? I'm definitely learning a lot! I have to build another incubator this fall for my corn snakes but it will be out of a styrofoam cooler since I will only have one clutch of corns. Then I'll work on buying my hotbox.
