The Aero 7+ is all copper (except for the aluminum sheath) . And what is even better about it is, the fins are skivved. This means it is all one piece, and the fins are not soldered to the base as many heatsinks are. Being one piece instead of soldered means better heat transfer.

Above you can see that sheath. It is raised more from the heatsink out of necessity and to make it work more effective. The original and short-lived Aero 7 had a problem with the fan motor overheating. This is corrected with the Aero 7+. Supposedly, being further away helps build air pressure better allowing the fan to better center the airflow.

The fan does run from 1900 - 3500 rpms. And we all know running some fans faster means more noise. Included with the Aero 7+ are the two fan controllers that you see above and below. You can't use them both, but you can use whichever is best for you. One goes in a 3.5" bay next to your floppy drive and the other goes in an empty pci slot. Now, "how 'bout that" (in Harry Carey voice) for choices?

Installation~

One good way to check and see if the Aero 7+ will fit your motherboard is to place an 80mm fan where the heatsink would go. If it fits ok, and you have a little extra room in the rear to attch the clip, then you should be ok. The picture below, on the left side, is with the Aero 7+ installed on a Shuttle ak-31 mobo. I had to remove the fan before I could attach the rear clip. Otherwise the fan was in the way preventing proper leverage needed to get that clip on.

As with any heatsink, you attach the rear clip on the mobo, and gently lay the heatsink evenly on the cpu (not at an angle) . Then attach the front clip. I am very happy to say the Aero 7+ has a 3-prong clip in the front and rear. They ALL should have that feature. To attach that front clip, no tools are needed here, just guide that front lever on the mobo catches. Piece of cake!
