As long as it was not long enough to raise the internal temp of the egg you will be fine. You may have an early hatch if your temp consistently runs higher.
If your temp is only jumping to 101 I would not worry. I have my bator set at 100.0. At times it varies between 99.0 to 101.3. As long as it is not spike and staying above 102 you should be okay. I think if you continue to do what you are doing with the windows and fans you should be ok.
