Hello
My goal was to reduce the disk memory so that it does not get warm so quickly.

"reduce disk memory" Don't you mean disk usage? Type this in a terminal and report back the output

Code:

cat /proc/sys/vm/swappiness

From what I see, your main issue seems to be RAM, your first post shows this

Memory Usage: 1330/1993MB (66.73%)

while your disk usage is reported

Disk Usage: 12/293GB (5%)

so maybe what you need is improve your memory usage not your disk's.
