Temps may be a little high but I don't think that would effect feeding too much.
I am assuming that this is a hatchling ... if not you may need some other tips.
Have you tried live pinkies yet? Also I have heard from other people that washing a pinky with unscented soap will help or making a cut into the skull ... frozen/thawed of course! One other thing that I have had good luck with is putting the snake in a deli cup (or some other small container or box) over night with the pinky.
Give him lots of time and quiet to settle into his new home. Only offer 1 meal every 5 days or so and if he doesn't eat for about 4 weeks (assuming he has already) you may need to force feed a couple rat/mice tails.
I know the frustration but try not to worry about it too much. Offering food every single day doesn't help.
