Ok so i was curious about the bolds it had on the back of the card and i decided to remove them and i came to find out that i had removed the copper contact with the GPU itself and the silver heatsink compound might have dried out a little.

so i decided to replace the silver heatsink compound with some crap silicon base heatsink compound that i had around. I figured that the temps might go down. I will replace the compound with arctic silver later on.

now my 8800GT is idling at 80C with 40% on the fan. the max temps of the card say that it can reach upto 105C but i sure dont wanna find out. I dont know how high the temps reach so i have the fan on a 100% playing games.

is the 8800GT going bad or will the arctic silver help bring the temps down to my old idling temp of 55C OR should i just get a VGA cooler?
 
Sounds like you`ve not seated the cooler correctly.
When removing the old stuff it`s importaint to clean the contact surfaces well, I use an industrial grade IPA (isopropyl alcohol) or surgical alchhol for this purpose.
If you`re getting 80C at idle, then playing games will push the temperatures well over this, I suggest you stop until you can reseat the cooler or run the risk of toasting your card.

I made sure to clean it with that 90% ispropyl alcohol. as for adding the silicon base compound--i added a pinch to the center (rice sized) and i moved it around bit to let the compound spread. I've already done it twice and still the same.
