How stupid are stickers on VPU heatsinks?

I got two stickers applied to an X800XL graphics card. The ATI one and then a Saphire one on top of that. They havn't even stuck them on straight and are about as exciting as having pictures on bank cards ie not very. Aesthetics aside what do the stickers do to the cooling performance when applied to what is quite possible a very nice copper heatsink. I think any stickers should be supplied seperately so I can stick them where I like and maybe that would turn out to be sticking them in the nearest bin. At the very least I would make sure to stick them straight. It's easier to apply a sticker if you want than to remove it if you don't.
