HD heatsinks

Sorry for the terrible image quality. They were taken with the snapshot feature of my videocam.

They didn't turn out as I had originally planned. I still don't have any temps because they won't fit in my shuttle.

A better design would have been one solid piece from the left to the right. These seem to emit a slight 'twang' with every seek. Still more testing to do.

wher exactly did you get those sinks?

Since the HS clamp to the sides of the HDD which is the most efficient heat conduction path, you could just try slipping in a pad ofdamping material like foam between the top fins and the top of the drive. This should decrease the ringing of the heatsinks and provide some noise absorption with little increase in temp.

They were small pieces of aluminium L-channel. About 6mm thick (3/8"?) and each side was about 5cm wide. I cleaned them up, cut the side that screws into the HD to a reasonable size and drilled holes in the top side. My dad milled the 'fins' at work.

Yeah I thought about that. I need to try and find some dense, thin foam.
