Hello. I just built my first computer with an AMD Athlon6 X2 4200+ with an A8N SLI Deluxe motherboard. After a while of running with only general use (windows media player music and Firefox), the CPU temp is at 52 C, fan at 3200 rpm, and 2200 MHz. I used the stock CPU fan/heatsink/ Does the temperature sound normal to you? Thanks so much.
