MK4 Hotend fan always running at full speed

I've had my MK4 for a year now, which was built from the kit last year. It's printing amazingly well, however I've noticed it's quite loud. The noise specifically comes from the front hotend fan, which always seems to be running at 100%, even with relatively low temperatures, starting at layer 0. Is there something I can do to address this? I've seen other MK4's run almost whisper-quiet.

RE: MK4 Hotend fan always running at full speed

Any update?

Just assembled MK4S and the hotend fan is so loud. It sounds like a blower fan. Going at almost 8000 rpm all the times.

Any help would be great.
