Hi guys from quickly looking around for a solution i found this seems to be quite common. What happens is my system boots (newly built so windows not insalled yet) it does all its stuff and gets to a screen and saying something along the line of cpu fan error (fan does spin). My fan is the hyper 212 evo from coolermaser and im running a asus p8z68-v pro motherboard. The 6 pin fan power cable is defiantly plugged into the cpu_fan slot. I don't have the slightest of clue when it comes to custom building but i read to have a look in the bios(first time entering it). From what i see it recognizes it and the cpu seems to be at a temp of 22c so im in no doubt that its probably working but the bar for the fan is flashing red (in the bios) and the rpm i think was also doing this, the rpm indicated was around 500 is this low and how can i change it, and what can i do to get rid of the error? many thanks reece
