As the topic says.... are VGA ramsinks necessary to use if I remove the stock cooling apparatus? I recall reading that they aren't necessarily needed, but I am sure it's not a bad idea.
it honestly depends on your case airflow, if you have super good airflow, you can go without them easily. Normally the flow near the card isnt the greatest making heatsinks absolutely nessesary. Either way, the cooler you keep the components the longer they will last for you.
guess it depends on the card aswell. I can't imagine my X800 GTO2 not having them because in its overclocked state, the ramsinks themseves almost get too hot to touch, and I have ok airflow too.
