Yeah, you should be ok as is. I do think though that an idle temp of 60c warrants concern. Is that panel just totally open like it appears or is there glass or mesh behind the left case panel? Take a little house fan and blow it into your case and see how that affects your temps. If you see a sizable drop you need to get better airflow in the case. There are some high CFM fans that really push a lot of air. Might help in getting some of that hot air in/out.
