I took the fan and heatsink out this week and blew the dust out of it. I've done this a few times before, but I never replaced the thermal paste, which is a must. Oops. So, I ordered some Arctic Silver, it should be here today. I have to clean the old off and put on the new. Wish me luck.
It should help keep the temps down.
Right now, it's not running hot at all, I've got the side panel off and a fan blowing into it. But as the day heats up it doesn't help much. So.....
