I recently built a new PC. It runs perfectly, it is very fast, and I have no problems whatsoever with it. The only thing is that sometimes it is nice and quiet with the fans at a decently low volume and then sometimes the computer is noticeably louder (the fans sound noticeably louder than they usually are).
Im not sure what I can do about this or how I can go about troubleshooting it. Maybe this is a normal thing and I should just ignore it? I was hoping I could get some advice here. Any input would be appreciated.
