| Full 040 in a 575. Need a heat sink? |
Posted by: MinerAl on 2013-10-03 10:48:49
I have a nominally 25MHz 68040 CPU that I yanked from a 9x0. It had a cute little heat sink on it, and when I put it in my 33MHz 475 the socket had the attachment tabs for the heat sink clip, so I clipped it on.
Now I'm moving the 68040 to a 575 board. The 575's socket does not have the tabs for the heat sink clip, and the original 68LC040 ran at 33MHz without one.
Will my 68040 get significantly hotter than the heat-sinkless 68LC040 that was in there? Should I bother to glue it on, or move on to more important issues?

because its a 25mhz full 040, they work @ 33mhz but do make some heat.
you can keep an eye on it, gets too much over 130-35 degrees you should put a heat sink on it.

It should just stay put with heatsink compound. Mine does in my 575.

you can NEVER go wrong with keeping ANYTHING that makes heat cooler.

Some heatsink compound and a 486 heatsink should work. That's what Daystar used on their IIci CPU upgrade.
