Whoever said "cooling chip" probably meant "heatsink". I don't own one but these pictures I googled up make it look pretty easy. Measure the holes on the board, at a guess I would say something in the range of 40mm?
Haha picture 1 and 2 are mine
I was unlucky and had a way to hot Lisa after installing the indivision AGA.
It dosn't look like the other guy mounted it with bolts/nuts, he probably hotsnotted it in place, i don't do that xD I did use spare GPU heatsink mounting bolt/nuts I had laying around and also did modify the fan a bit to make it fit better. Only one hole is avaliable but using a slow 40mm fan that is sufficiant enough
As you see Punky~ it's no trouble adding a fan to cool Lisa, some hacksawing and you can keep the hdd cradle also
Edit: Here is my Indivision AGA MK2 mounted without the fan, only one hole avaliable for mounting a fan :/ (under the ground wire).
