Hi random194,
Thank you for using the Apple Support Communities. We understand you're seeing some fan activity on your Mac. That's definitely something we would be looking into also, and we'll be glad to see how we can help out.
When the issue occurs, are you also seeing the "deleted" process running high in the % CPU column of Activity Monitor? View CPU activity in Activity Monitor on Mac
This may be worth taking a look at as well, as there are a few other factors to consider when you're noticing a lot of fan activity: About fans and fan noise in your Apple product
Some Apple products have vents that let fans bring in cool air and expel hot air. Make sure that the vents aren't blocked to allow your device to perform at its best.
- Apple TV 4K has a fan and a vent at the bottom.
- Airport Extreme and Airport Time Capsule have fans and vents at the bottom.
- iMac has vents along the bottom edge and on the back.
- iMac Pro has vents along the bottom edge and on the back.
- Mac mini has vents at the bottom to bring in cool air from beneath the device and vent hot air from the back.
- Mac Pro has three fans on the front of the computer and vents on the front and back.
- MacBook Pro has vents along the side and on the back. MacBook Air computers have vents along the back near the clutch.
The surface your device rests on can block its vents, affecting fan behavior. If you use your device on a soft surface like a couch, pillow, bed, or your lap, its fans might run more. Using your device on a hard, flat surface like a table or desk is best for temperature control."
If the above does not seem to apply to your usage, you might also try a reset of your System Management Controller to see if that helps: How to reset the SMC of your Mac
Let us know if that helps.
Have a good one.
