That makes a lot of sense. I'm going to have it looked at I think it needs cleaned too and I will look at trying to find out the temperature. I was wrong about the other render though, I realized that I had left checked match scene size or whatever rather than exact resolution so it wasn't rendering big which was why it was faster. I'm rendering the second one now I think i started it around 2am or so so it's past 12 hours now. Then when it's done hopefully I can figure out if there is something wrong. I just wanted to at least send the other render to go overnight so it would take last time. I've had a few pictures I've had waiting to be able to render them for over a year, I got a little excited with it not locking up lol.
