I have all my fans set to 100% in the BIOS, you can set it in there. Yes, this should reduce your temps more if the fans are not already at 100%. Try running P95 for atleast 6 hours to see if it is stable. If it is, try lowering the vcore by the smallest amount, and then run P95 again for atleast 6 hours to see if it's stable. Run it for 12 - 24 hours to see if it's completely stable. If your temps are still above 60C I would suggest getting a third party cooling solution for your CPU, make sure it's the correct socket before you buy the CPU cooler.
***First***, take a look in CPU-Z, what does it show your vcore to be? And look in the BIOS, what is the vcore set to there? If I know those two numbers I can help you more on your overclock.
