I recently took my desktop computer to a tech professional for a thorough cleaning, and when I brought it home, I noticed that the fan is now significantly louder. The technicians cleaned all the components individually, and while the inside looks spotless, the increased noise is concerning. I've read that fans can sometimes seem louder after a cleaning because all the dust that was muffling the sound is gone, but my husband insists that it's much noisier than before. The fan runs especially loud when watching videos, to the point where we have to increase the volume substantially to hear anything. I'm hoping someone can shed light on what might be causing this and if there are any potential fixes. I'll do my best to answer any questions, though I'm not very tech-savvy.

It sounds like the heat transfer might not be happening properly. If the air coming out is cool, that's good, but you need to have hot air coming out as well—that shows the heat is getting expelled. I'm curious if the techs reseated the components correctly after cleaning and if they reapplied thermal paste. That can make a big difference in fan noise and performance.
Have you installed any monitoring software that tracks your CPU temperatures? If you haven't, there are free options out there that can show you what's going on. Knowing the temperatures can help determine if the louder fan is a problem.
