I know we were talking on another thread about cooling down a humi. I have no problem with the blue cooler blocks in the coolidor. However I don't think they work so well in desktops. I have a real problem right now and I need to get it corrected really fast. My desktops are out of direct sunlight, but the apartment with patio door open still is sitting at 75 degrees. both of them. I need some really good ideas really soon. I have a desk fan blowing across them, I need some good ideas here guys.
