I have an ASROCK Z97 Anniversary Motherboard, and an NZXT Phantom 410 chassis. I have just completed the build, but now whenever I turn on the PC, the case fans run at standard, but after the BIOS screen disappears, the case fans go 100% for about a minute, then go back to standard. Any possible solutions? Btw in the BIOS all the fan speed settings are set to standard.
