1987 SPG fan runs for 5 minutes

2 things:
SPG fan runs for 4 1/2 - 5 minutes after shut off. Every time. I know its normal for fans to run, but for 5 minutes consistently? It's been doing this all summer. Lately its been a bit cooler and the fan has run on low for a while instead of high after shut off.
Also. She revs to 1800 immediately on startup after sitting overnight. Then immediately comes back down to a normal 900 and runs fine all day. It used to have a horrible varying idle which was fixed by replacing the MAF sensor. Now its just this.
Like I said, new MAF sensor. Also a new IAC valve. There are no vacuum leaks. Cleaned throttle body and got a new air filter. The previous owner says he replaced the coolant temp sensor. However, I can't be sure if this was done in the past 2 years or the past 5 I don't know. I feel like I should get a new one just to be sure.
What do you think?
