I've got a 2020 MacBook Air (13 inch) that used to run smoothly without any overheating issues for the first few years. Lately, it gets really hot and the fan kicks on even with just a couple of tabs open in my browser. The noise gets especially bad when I'm charging it. I remember being able to use it in class without any noise distractions, but now the fans turning on can attract a lot of attention, which is super embarrassing. I've heard that dirty fans or using Chrome instead of Safari might be the culprits. Can anyone help explain what's going on?

It sounds like you might be dealing with a couple of issues here. Firstly, if your MacBook Air gets loud and hot, dirty fans could definitely be a problem. If you're up for it, grab a pentalobe screwdriver and some compressed air to clean out any dust. It's also true that Chrome can be more resource-intensive than Safari, so switching could help reduce the heat a bit. If you're comfortable with DIY, resealing the thermal paste on the CPU after cleaning could really help your situation! Good luck!
Honestly, if you're regularly dealing with overheating issues, it might be worth considering an upgrade. The newer models are way more efficient and handle heat better. If you're still interested in fixing your current one, just clean out the fans with some compressed air and check which browser you're using!
Both the dirty fans and Chrome usage can cause overheating. I suggest cleaning your laptop out first—buy a can of compressed air if you're going to do it yourself. If it doesn’t help, sticking to Safari might ease some of the stress on your CPU since Chrome is pretty heavy on resources. Plus, if you're feeling adventurous, you could apply some new thermal paste, but proceed with caution!
Just a heads up, MacBook Airs actually don’t have fans if you have the M1 model. If yours is an Intel version, those do have fans, and it sounds like they might need a cleaning. But the overheating could still be a mix of browser workload and dust buildup. Maybe it’s time to think about a new laptop if cleaning doesn’t fix it!

Yeah, I really want to sort this one out first before spending on a new device.
