With cards like THIS one which have a metal plate for the VRAM, is any additional cooling necessary?

I was wondering if I could get away with just a universal GPU block, or would I need some direct airflow over that?
 
You need airflow over it. I tried it with my 780 and it's cooling plate but it just couldn't handle the heat from the vrm's and memory. I bought a copper 1u cpu cooler off the bay and cut it to make a heatsink to cover the vrm's and had individual heatinks on the memory chips. This was fine when I had a 200mm fan fitted to the side panel even when it was only running at a silent 480rpm. When I made another window for the side panel without a fan the normal case airflow couldn't keep everything cool so I had to bodge a quiet 80mm fan to blow over the heatsinks. In the end I bought a brand new boxed set of Watercool Heatkiller Z87 motherboard vrm water blocks from OCUK's ebay outlet for less than a tenner and mounted one of the blocks on a copper sheet cut to fit the vrm area of my 780. It works a treat but I had to use 90 degree rotaries to get from my home made vrm block to my EK Thermosphere core block. It doesn't look that good but it does a excellent job. The next card I buy I am looking at doing something that's neater and more efficient.

The best I could find is using an Antec spotcool. I did that for a friend's computer with a universal block and some cheap heatsinks and it's been going strong 2 years, but IMO the spotcool still looks ugly.

Oh well, guess I'll stick with full cover :/
