Hi BE,
I can get you the ak350 and send it over if you like.
did you see my gfx cooler i made from the ak350 ? is that what you have in mind. The base of the ak350 is 5mm at it's thickest.
i havent mounted this yet as i need something on the back of the card to support it and it needs at least 2mm of the base.
On the thermal take base i took it down to 3mm and it made no differance on the temps. i will take it down to 2mm this week.
