Air fans Question

I have had this p.c. for a while and have been experiencing CPU overheating sitting steady at around 87-95 degrees under load with spikes of around 100. I noticed that my fans look like they are oriented the same way (all exhaust). Should I flip the two back ones to make them intake?
