I have a Asus P7P55D-E motherboard, Antec Solo case and a Core i3 540 processor with the stock cooler. I was wondering why my CPU idle temperature is so high? It idles around 40C according to the BIOS and PC Probe II. The case temperature is 28C and the CPU fan speed is 1300rpm. I've read else where on here where most core i3's are idling at 20C - 23C. Any thoughts. Also, this is a new system so dust isn't a problem.
