overclocking on some motherboard

i know overclocking depends on the motherboard, but do the temps depends on the motherboard ur using?

im using p5n-d ,q6600 and overclock G0 to 3.2ghz., idle at- 35 and load at 45.

my friend's are p5q and q6600. also using the same cooler as me. silent knight. but his idle is like 29.

id say it depends more on the case and airflow setup in that case
i dont think the mobo will affect it much unless its pumping out mad heat somehow
