Help with WC'ing 8800 ultra

[MJOzolins]

May be a stupid question, but does the HSI on my 8800 ultra really need a heatsink??

For reference: http://www.thermalright.com/new_a_page/download_images/booklet/hr03_plus/hr03_plus.pdf

I basicly have passive sinks for everything else besides that (Using a d-tek block for the GPU).

J/W if anyone could comment on this, I know most of you use full cover blocks or uni-sinks tho.

Most definately. Its the second hottest part of the card. Behind the core that is.

I run my card naked w/ just an MCW60 in hot Hong Kong summers (upwards of 30 degrees) just fine with the overclock in my sig.
