I have a large soda cooler I was able to get and have converted it into a incubator for ball python eggs. I am using a Helix DBS-1000 for the thermostat and have two 92mm fans that blow 31cfm, one at the top right side and one at the bottom left side. I have a few digital thermometers measuring temps constantly. I have noticed that the temps are stable between 87.3 and 90.4. However yesterday I noticed the high temperature in one of the test tubs I have got up to 91.7. Is this a problem? I keep the incubator in my snake room so it gets a little warmer in there but never above 85 degrees ambient probably. If I add two more fans will that keep the temps more stable or are they stable enough as is? Is a spike to 91.7 acceptable if its not constant just during the hottest part of the day on a really hot day? Thanks in advance for any advice!

I also added dry erase board to the sides of the incubator so I can write on it info I may need. Cheap to do $10 a sheet at Lowes!
