weird buzzing sound

[andrevaux]

I started having this kind of low pitched buzzing sound coming from my gpu about a month ago and Im so confused. I thought it could be coil whine but irs always there, quieter while idle and louder while playing and in general its not really loud even though is still a bit annoying. I dont think its a fan because i recently cleared them from dust and the card has just 4 months. So what could it be? (also if i know its just a sound ill just endure because as i said its not really loud but im just scared that something could be wrong with my card)
