Hang in there! This same thing happened to me, on lockdown day went to bed all was good but woke up to a BAD egg smell in the house. The temp had spiked to108 over night. Oh wow was iI a wreck! Got it back down to 99... maintained for several hrs and felt OK to go on about my business for the day. Got home 8 or so hours later and tell was 90, next afternoon it was 106. Humidity throughout lockdown was 30-50. What a mess! Anyway, after posting here I got some very good advice, dipped the eggs in water to help with moisture, laid soaked paper towels down and so on... and most did hatch! Perfect little chicks 
They were shrink wrapped and had to be helped out of the shell. So considering the age of your eggs I wouldn't worry. Just make sure the humidity is correct after the heat. Good luck! Keep us posted!

I did a smell test and one failed. I cracked it open and it was definitely dead. It was a nicely formed light Brahma. You could even see its little leg feathers...... The one with the air save on the side is moving like mad! I'm fighting for this one. My luck it will be a mutt rooster, but its a tough little bugger. Fingers crossed.
