Neccta :
I just installed my new Zalman 9500a on my am3 socket. The problem that I have is that the fan must be facing up/down for the clip to attach, and not sideways to allow maximum air flow. And now I can't install my memory cooling because it is blocking the memory. Is there another way to install it on am3 to change the way its facing?
Pardon me asking, but is this the retention clip you're referring to?
I haven't worked with the AM2 retention mechanism before, but the LGA775 mounting clip is able to slip between the heatpipes to allow for a horizontal mounting configuration. Seeing that the AM2 bracket looks very similar, I wouldn't be surprised if you can also slip the clip across the heatpipes to allow for a horizontal mount.
I took a picture about of my 9500A to illustrate what I'm talking about. Pardon the poor picture quality.
