Hi, Recently the fans in my MBP have randomly started spinning up to like 10000rpm, way past what the fan was designed for. Everytime it happened I shut down the computer to avoid damage, and when I turned It back on again it would be fine. It happened again today and this time, it’s persistent. On boot camp, the computer runs really hot and this only happens while doing something such as rendering. Is this a faulty fan, or could this have something to do with the logic board sending way too much power to it (I find that unlikely because it always fixed itself). I already tried an SMC reset, and opened the laptop to confirm it was indeed the fan. Here’s a video of the issue: https://youtu.be/ArGPcoQJkMQ It’s ONLY the right side fan. Thanks, John.
From my experience- it could be fan bearings. I had similar issue and all time help if I hit fan in the middle - but just for few minutes and after similar “sound”.
Clean out fan grills of fluff and debris. Check the quality of thermal paste between cpu and gpu on logic board. Replace as neccessary. Machine runs nice and cool now!
