My soutbridge w/ the kt400 never gets "hot" although it does get a bit warm to the touch sometimes....and it actually doesnt even get airflow beacuse its being covered up by an ide cable even though it still just gets warm to the touch (w/o heatsink) i put a heatsink on there anyway just for fun.
hahaha welllllll......i just remembered.....a long time ago when i was NEW w/ computers like i barley knew anything i could install a video card etc etc i had bought a hsf for a 2700+ i think and it turns out it wouldnt fit on my video card sooooo.....i figured i might as well put it on something that gets hot instead of letting it sit and go to waste and i actually stuck it onto the hs that was on my NB already.....hahahahahaha how embarrasing
glued it? have u already removed it? if not, then stick the mobo in a anti-static bag, put it in the freezer, keep it in there for about 20 minutes and u should be able to pry it off easily
putting it in the freezer expands the thermal glue, making it brittle and easy to work with
if this doesnt work, stick it in the freezer again for another 20-30 minutes and it should be very easy to pry off, but remember, dont leave it on for over an hour, freezer burn or condensation may develop inside the mobo, like in little crevices and it may short circuit something, so be careful when doing this
