Question Got a new gpu, is it okay to set manual fan speed?

Jun 26, 2019
Hi guys,
As it is shown on the title, a month ago, I bought a new gpu an AMD RX580 gigabyte version 8gb, however when I play any game the temperature goes up to 75C, almost everytime, and when I took a look at the fan speed while it is on automatic, I found it working with only 30-35%, so I wanna ask you guys is it okay if I set a manual fan speed (not that crazy but more then the automatic one) is it okay or is it gonna harm my gpu?
p.s : I'm living in a hot country, not that hot but yeah. (25C to 30C)
Thanks in advance
