It was migrated at least twice over the years from older Mac's, but it seems to be working fine in HS.

I forgot to mention at the time when I ran the test, Fire fox was open at the time with a couple of windows open and tabs as well which I believe may have affected the results. Before I run the test again. Is it best to do it with fire fox closed?

Looks like removing Firefox helped some. That iCloud stuff doesn't look great. I think High Sierra may be slightly buggy syncing and uploading to the cloud on a mini. Maybe try getting into preferences and disable iCloud updates. If that makes an improvement you could try re-enabling one at a time until they are all done? I only say this because my iTunes sync is a bit wonky between the mini, iPod, and iCloud. Doesn't slow me down but there are not 12 pending uploads either.

So I tried running the hardware diagnostic and it came up with this message: "There may be an issue with the System Management Controller (SMC). Reference Code: PFM006


Could this be the actual issue?

The fan is constantly on but the temperature seems to be normal. Searching around the internet shows that it might be the HDD temperature sensor. Any thoughts?

Actually your Mac Mini is running cold, because the fan is running at full speed.


1. Try resetting the SMC, as per > How to reset the System Management Controller (SMC) on your Mac - Apple Support

2. I'm not familiar with the monitoring utility, but it looks like the Intel GPU could be causing the fan to run full out.

I actually dis-like suggesting that you install another monitoring utility (given your current other problems), but it might be worth it to compare the readouts.

For some reason one of my post didn't show up. There wasn't any difference with iStat and Mac Fan Controller temperature readings.
