I undervolted my i514600k and im getting low temps while gaming and max 88 when full testing in cinebench, got 24k points but my vcore is like 1.4 all the time and reaching spikes of 1.5 , is bad in the long run ?

my temps are low in general. (those temps are in gaming)

When not gaming my cpu in on like 40c

while gaming gets like 55 to 72 max.

i did a undervoltage of -0.100 in bios , should i lower more ?

i did put my pl1 and 2 in 180w and my icc max in 307A .

im new on the overclocking so i used gemini and some youtube videos to guide me on this config . can i change anything or should i stay like this ? my perfomance and temps are good the only thing troubleling me is the vcore voltage.
