there's several options.
1) reduce voltage of the chip and increase clock speed to keep the power envelope within ~95W.
2) buy another motherboard designed with more than crap for power regulation onboard. I suggest the gigabyte GA-990FXA-UD3... I have two and I rarely if ever buy two of any motherboard model, I am anally picky when it comes to features and reliability.
3) thermal-epoxy some tall heatsinks onto the vreg chips and hope they last a while.
