Anyone had experience with these cooling products?

I've been considering upgrading the cooling on my video card. The GPU itself stays within comfortable temps for now even running it at 1100 Mhz, but the ram chips came without sinks and the MOSFET section makes use of a super thick thermal pad.

I've been looking at this for the VRAM chips:

And this for the MOSFET section:

In both cases I would skip the sticky pads they come with and use thermal adhesive.
Does anyone have any experience with either of these products or comments about their quality/suitability? The target video card is listed in my sig.

It's not going to hurt anything as long as they'll fit under the heat sink (space it tight on the Myst).

Really best way to upgrade is put something like an Antec 620 on it.
