No quite the opposite actually as these Ryzen CPU s thermal throttle at 85c to reduce temperature so you get better performance as they can boost fully without getting too hot under stress.
This is in a gaming/intensive use context as benchmarking software like Prime95 or Cinebench push the CPU up to 85-95c sometimes.
I would try incremental offsets i.e. - .050 then run your PC under idle and gaming.
Rest, back to the BIOS and aim for - .100 and test again.
This is on a 2700x so yours will be slightly different results being a 2700 and also the fact that every PC is unique in terms of hardware/performance.
If you run in to any freezes/BSOD/adverse performance just put your voltage back a little or reset your BIOS if you...
