Heat!!!!!!

[MachineDr]

I have seen a lot of posts regarding heat. I also saw a post that had a package of various sized heat sinks that appeared to be attached via double face tape (please correct me if I am wrong on this).

There is something that everyone should be aware of. Just placing a heat sink of the component that generates the heat is not the best way to go about it.

A heat sink works optimally when it is bolted to the device (the screws help conduct heat) and more importantly, you must use heat sink compound between the top surface of the heat generating the device and the botton surface of the heat sink. Metal to metal will help dissipate the heat but the compound actually helps transfer the heat from the genrating device to the sink in a more efficient manner.

So while you may have some success just attaching the sinks as it appears that has been done by some you can get optimal performance utilizing the compound as a conductive agent.

Also, to be MOST effective, the heat sink should be designed with fins and extend out of the enclosure (as some older 1541 sink kits did). It will mean cutting the case but it is well worth it in the long run.

This is especially true for Andrew as I saw a pic of his set-up and his drives are stacked on top of each other. Installing the heat sinks will make stacking a little harder, you will have to create a little shelf system for them (that's what I did after installing my heat sinks.

I hope this helps some of you out.

I assume you're referring to this photo, which is currently on my BBS's website:


Those two stacks of 1541's underneath the printer are all non-functioning drives...  AKA "Printer Stand".  The printer does work, and it's what my BBS's Userlog is printed to.  

The drives on top of the desk hutch are what are actually used on the BBS.  Primarily the Lt Kernal hard drive, but I have the 1571 and 1581 set up for transferring files to and from the hard drive, as well as for making backups.

But thanks for the tips on heatsinks, nonetheless...  :tummenupp:
