Heat sink addition

[Synesthesia]

To make my system at least a little bootleg, I want to attach a heat sink to my current stock 8800GT heat sink instead of buying an entirely new one. I happen to have allot of very nice heat sinks that are the right size lying around, and possess arctic silver thermal epoxy (It works extremely well). The question is, will slapping an aluminum heat sink on the stock one work? I can't see why not...but I want a second opinion before doing it.
I want to cool it better because right now at 2000 mem by 720 core it gets very hot running Crysis all very high with shaders on medium (anything else jacks up the game for some reason...not in terms of fps, but the color and everything else) and no anti aliasing.....4000 rpm fan at 79c, 35 fps. So its very loud and still gets a little too hot. (Btw, my computer room is usually 78 degress Fahrenheit, which doesn't help me)

Oh yeah, does anyone know how to remove heat sink foam from the bottom of an aluminum heat sink?

i would personally not suggest a home made heat sink unless it is as big as the accelero (pic below on my 8800gt) as the 8800gt is a very hot card and needs a fan or a big heatsink


i would deff suggest the accelero rev 2 made by arctic cooling it is only £15 (about $25 i dunno)

it is very effective cooled my 8800gt down from 45 to 50C C to 38C and it is a passive cooler surprisingly effective

If you can make effective, uncompromised contact between the two, then I don't see much problem other than possible strain or trial and error, so as to get temps better than they are stock.

I dunno if it'd even help that much.

WOW, thats a big heat sink! I want to add one in the current stock fan heat sink, rather than replacing it with the additional one. I currently have a 80mm slot fan underneath the gpu to take out hot air, but I think I could get it to suck air through an additional heat sink which would cause forced convection (this is good).

If I decide not to do this I was looking at a thermalight heat sink that goes around and above the card; this one seems to be the best in existence right now since the heat does not radiate onto the card.

lol...I just noticed after looking at the bottom of the gpu in order to determine its heat sink addition suitability that the graphic of a girl is cracked in many different places. It didn't come like this....I bought this card in large part because of the hot girl on it...maybe the heat did it? Sob....I guess thats what 80 Celsius can do to it.

Is that the psu on the bottom of your case? What kind of case is it?
