Right.

These were the "early" days of CPU of any power at all. IBM PC was 4.77 MHz and the Polaris had an 80186, yes?

I figured it wouldn't hurt it any considering I'm using good stuff on it. Cooled the power supply also. Since I was pulling ALL of the chips ans spraying them lightly with canned air, I'd do a total job.

It probably does reduce the temperature, but I don't
think we ever had any problems caused by the hot CPU.
They're rated for 70C, or 158F, which is pretty toasty.
If you really want to cool it, you could attach a finned
heat sink to the socket cover. They make ones that have
adhesive backings.
