I have a Be Quiet Dark Rock Pro 2 running on a Gigabyte Z77X-UP7 intel 1155
so naturally I'm trying to overclock, but I'm having issues with the fan speeds, ie it does not seem to increase, when trying the OC software
it only seems to run at 600rpm, I also had to turn the rpm alarm off in the bios
any help is greatly appreciated, if more info is required let me know
cheers
