For my cooling experiment i need 15V inside the computer. Is there any way, by combining wires, modding the psu, to get the extra 3Volts. Ampere needed is about 1.5. I currently have an 8 degree celsius CPU. On full load it rises to quickly to 60 celsius (matter of seconds), so i need more juice. Ideas? My PSU is an Astec AA226OO +/- 425W High priority.
