That aren't that bad temps, they're a bit high but it isn't terrible, average idle is about 30-40°C. I get 37°C when Idle and that means nothing is nothing is running and I use a watercooler which is better at transfering heat than air. So, with those temps you should be fine. They also shouldnt be in a range of 10°C difference so check if you're not running anything in the background when checking the temps.
