I'm thinking of doing some mods on some old Athlon XP heatsinks and putting them instead of the stock cooling on this board. If the heatsink in the PW area is also tall enough it will get some air from one of the two fans of the Ultra 120 and it will really reduce temps. This combined with a bolt-on fit and the other fan at the rear of my case should reduce temps drastically ... I'm thinking aluminium instead of copper. Any comments on this idea?

BTW, after hours of normal pc usage the PW area temps are 52 Celcius (bios reading)
