I have a new build(one month old) and the last coupole of days i noticed that when i play(heavy gpu load) sometimes my fans make a weird buzzing sound. Now i think this is not a kinda of coil whine kind of situation because i've seen enough videos and it's not similar to that. I have tested the fans themselves up to 100% RPM on 0% gpu load and it doesn't seem to be a problem with them per se. The sound for some reason goes away 4-5 seconds later after i remove the left side case panel thus increasing the airflow. I have also noticed that it is not vibration related, refering to the side panel. Maybe something else? Because as i said before the sound goes away after a few seconds and not the instant i remove the panel. Any suggestions? Also most of the time the sounds goes away itself after a few minutes in the game and it might come back later, i just don't get why it would start doing this now, a couple of weeks after i built it.
