Before starting up TOS, my GPU fans are at ~1000 RPM. When I start TOS and it goes to the server select screen, the fans slowly rev up to more than 2200 RPM. Another culprit is the character select screen wherein the fans are at ~2000 RPM. When I enter the game after choosing my character, the fans go down to ~1700 RPM.
I tested this using Open Hardware Monitor after observing that my pc fans sounded like jet engines when TOS entered the server select screen. I have tested this countless times. I even watch the RPM slowly rev up from 1k to 2.2k as my pc fans start roaring louder and louder. I tested other games (CS:GO, Dota2, L4D2) and saw that no other game revs up my fans to more than 2000 RPM even at maximum load (they usually stay somewhere from 1500 to 1700 RPM).
