There will be lots of times I do not even turn on the chiller (EDIT:...probably NOT), as cold as the res gets.
I usually use the computer Fri, Sat, Sun and am away at work the rest of the time, Sometimes however, I have weeks off and the computer gets used everyday.
Better safe than sorry I guess. How fast do you think the grease will eat the Dragon Skin, and does that really even matter?
EDIT: grease is pretty permanent right? No way to get it out of the socket?
