Just a bit above normal, though not critical. I would advise you to check cooling of your case - if it is near the floor under your desk, surrounded by other objects etc then you should move it and make sure it has plenty of clear clean air-flow around it. Also check all fans and inside of case and de-gunk and clear all dust off everything. You could also check cables inside case, especially if of the flat/ribbon type - could be changed for Round type taking up less space and allowing clear air-flow through case.
Never take side off of case to keep cool, only makes matters worse.
