- It got to about 29 degrees here a couple of weeks ago, and the Supra was
- feeling VERY hot. It was still working fine, but I wasn't sure how much
- longer it would be. Thus came the Supra Heatsink Hack.
-
- All I did was get two large finned heatsinks, and sandwich the Supra between
- them. They are larger than the modem's case, and provide some overlap. Between
- the two heatsinks to keep the modem in place (on either side, not through the
- middle) I put four bolts. On the bottom heatsink, in four other holes I put
- four PCB spacers with rubber feet on the bottom (to keep the bottom heatsink
- from scratching the desk).
-
- Now the modem sits sandwiched between the two heatsinks. It never gets hot,
- and has to be on a long time for me to feel any warmth. I could have used
- that white silicon heat transfer compund but it works fine without. No
- modifications to the modem are needed. The complete unit is a bit bigger,
- but it's still out of the way on a big desk so that doesn't matter so much.
-
- P.S. If someone ever offers you a PDP11 machine for free, take it - the
- heatsinks and other hardware came from a PDP11-05. Other parts of the same
- machine have also been very useful. You can get rid of the bits you don't want
- by finding someone who REALLY wants a core memory board to display in his
- office, and making him take it all.
