get those small chipset cooler hopefully it'll help reduce them .
this is one of the reason i never settle down with lower spec mobo ^^,
they lack of cooling system

erm try find a user by the name Roberto.Baggio .
he's selling thermaltake small heatsink .
try this method .

in that case find mr niclasteoh .
he's selling both alu and copper version .
iinm, the aluminium could contains more heat compared to copper .
but copper absorbs and dissipate heat faster than aluminium .
