i recently put more fans in my computer to lower temps because they were reaching high 50's. it got down to about 42 idle, and goes around 46.5 while im running Command and Concour: Zero Hour. I know these arnt bad temps.. but seems like it could be lower by changing speeds/direction of fans. I have a total of 4 TT smart fan II's, an adjustable speed fan that came with my power supply, not sure of its ratings, an exhaust fan on the power supply, and a blower that pulls air directly from the heatsink on my GPU. Right now, i have the side fan, both back-top fans (two of the smart fans), the blower, and PSU exhaust all pulling air out, and the two on the bottom front (other two smart fans) pushing air in. All of the smart fans are currently on highest speed setting partially because i wanted to see how cool the processor would get, and also because i wasnt sure of where to place the sensors to control them. Are the temps fine? and should i use the sensors or just leave the fans on max (their damn loud on this setting.)
Mainly.. what directions should the fans each point and should i put them on variable speeds at all?
