PRODUCT WALKTHROUGH & PICTORIAL
For a measly US$20 you will receive the following.
The actual heatsink is practically identical to the standard heatsink packaged in most earlier retail models of the 478 Pentium 4. With 24 aluminum fins spanning the entire length of the heatsink, surface area should not be a problem. The only real difference is the clip and fan mechanism.
Each corner of the 4PRO L comes equipped with one clip that allows you to take advantage of each of the four openings in the standard 478pin bracket attached to all recent Pentium 4 motherboards. Now I know that the clipping mechanism shouldn't be a major concern seeing that it is usually a one time install, but this particular heatsink is a pain. Not only is the spring attached to each of the clips waaay to stiff, but also makes the heatsink very difficult to attach without have the heatsink base rock on the Pentium 4 heatspreader. You have to hold the heatsink very firmly in the center, attach the one clip, then attach the diagonal while still pressing down so the heatsink does not become misaligned. Then you can attach the remaining clips for a complete install.
I know pressure will allow for a better thermal sound mating surface, but only to a certain extent. Once finally attached, I was so unnerved that I checked the bracket to make sure it wasn't pulled out of the motherboard or warped in any way.
Another problem I had was that there was no protective plastic covering on the base. Although the aluminum base "had" a beautiful highly polished surface, the lack of protection left the base scratched very badly.
To counteract the scratches, I applied a small amount of Arctic Silver 3 and smeared a light coating all over the heat spreader contact area. After, I removed the excess by buffing with a dry paper towel.
Although it doesn't look pretty, all potential air gaps were filled with thermally conductive paste. Even if your heatsink is perfect, I still recommend anyone do this to make sure all gaps are filled. Your temperatures will thank you.
