I recently got an Acer Nitro 18 A-I laptop, and it was super quiet at first. The fans would occasionally spin up during normal use, but they usually settled down to total silence. After I added a WD Blue SN570 2TB SSD for extra storage, I've noticed that the internal fans now run at a low level instead of being completely inactive during idle or non-intensive tasks like browsing the web. They will sometimes turn off completely but often go back to that 'just active' state. Everything else seems to be functioning well, so I'm curious—what does this increase in fan activity indicate? Could anything have gone wrong during the SSD installation, or is this normal? It's still within the 30-day return period, so should I be worried?

One possibility is that your SSD is near a temperature sensor that's triggering the fans. Even when it’s not actively being used, SSDs can still heat up a bit from background processes like wear leveling. It's not uncommon for fans to become slightly more active after an upgrade. Keep an eye on temperatures, but if everything else is functioning, it might just be a normal adjustment.
No worries, it sounds like you did it right! Just monitor it for a bit. If the increase in fan activity becomes more pronounced or bothersome, that might warrant a closer look.
It sounds like your new SSD is generating a bit more heat, which could be causing the fans to kick in even when you're not doing anything intensive. Laptops are quite compact, and airflow can be restricted, so a new component might change how air circulates. I'd suggest removing the SSD and seeing how the fans behave—if they go back to being silent, the drive might be the culprit. Just make sure to handle it properly!
Gotcha! I didn’t disconnect the battery when installing, which I know is best practice, but the stickers made it tricky. Do you think that could have caused a short or something? Anything I can check to rule that out?
It's always best to be cautious, but typically, just installing an SSD shouldn't cause a short unless something went really wrong. You might want to run some diagnostics just to be safe.

Thanks for the insight! I can definitely keep an eye on the temps. I did replace the heat flap over the SSD, and it felt good—just making sure I didn't mess anything up during the install.
