It looks much worse in pictures than it does in real life, so this base is not as bad as you see it in those pictures. The fins are made out of aluminum and they're very thin, about 0.3-0.5mm a piece. Copper base with aluminum fins is a perfect combo because copper transfers heat faster than aluminum, but aluminum dissipates it faster.
There are a total of 34 fins, inserted into the base of the heatsink. AVC calls this technology Crimp Fin Technology: Fins inserted into grooved base plate. Base plate fin spacers pressed firmly between fins. Insertion is not the best way to join two materials for optimal heat transfer but it's not the worst either and in this case it was either that or soldering/welding.
From what I could see, the fins are also melted on the part that comes in contact with the base, so maybe AVC forgot to mention the soldering or my eyes played tricks on me (after all, it's a very small space between those fins and I could be seeing things that aren't there). Because these fins aren't very solid, the fan could not be attached using the traditional four screws, so AVC went for a more subtle approach and used a cover, or shroud, that protects the fins from bending and holds the fan in place.
This cover catches on to the base of the heatsink with two pairs of clips on the lower side, so it's easy to take off in case you want to clean the heatsink or re-arrange the fins when they get bent. The cover also has another job, and that is to make the cooler look ... well, cool. AVC even engraved the cooler's name on this cover, see the upper right corner of the picture. The fan used to make this HSF complete is made by AVC, measures 70x70x15mm, spins at about 4200RPM and it is supposed to have an airflow of 34.947 CFM.
According to the label on the back of the fan, this is indeed an AVC model (F7015B12HN), so it means that AVC manufactures this cooler entirely. Kudos to them. Too bad though there's no mention of the noise level of this fan, but I can tell you it's pretty loud. It's not screaming like those Deltas, but you can definitely hear it when it's running. It makes a moderately pitched whining noise, which is normal for ball rearing fans. Because the cover doesn't have clips mounted, like the stock Pentium 4 coolers do, AVC supplies a set of clips with each of their coolers.
These clips are made out of steel so they're pretty solid. Still, these clips are easy to install and they don't require much pressure. Another cooler from AVC is the Z7H2403. Unfortunately, this cooler does not have a "stage name" yet, which makes it hard for me to refer to, but I'll do my best.
