Got my 512 OLED yesterday, i noticed my fan speed ramps up and down (50 - 60⁰C) in idle mode (just surfing through Steam libraries and menus). Fan ramps up about every 15 seconds, the fan itself is pretty quiet but it makes a weird sound when it ramps up, sound like a smal zipper. Which is pretty annoying. First i thought i was the speaker crackling, but its 100% the fan.

The fan is pretty quiet, even at high speeds but its the zipper sound that bothers me when it ramps up from 0. Anyone something similar?
