In a 610, the CPU chip is very close to
the power supply and that is a determining factor on the size of the heat
sink.
actually when I replaced the chip it was on the complete opposite side of
the MB than the power supply and I don't think anything else was in the way
but when I bought the
My mistake, it was the hard drive and cables near the chip.
ahh yes the cables could possibly get in the way (or melt themselves on the
heatsink) but I think I have to build a new case for the 610 anyways in
order to make room for a fullheight drive and aditional powersupply (and a
few ccfl tubes)

Well, I dunno about this. I have a 33mhz '040 with no heatsink in my Q605

wow...well im glad I found this out..
would it work fine to take any heat sink that was big enough and just
attatch it with thermal glue?
I don't trust thermal glue any further than I can throw it, especially because
it's usually next to impossible

Motorola often substitutes an 'X' for the 'M' in early runs of their

Such a full function chip would read: MC68040RC33B, and this would

Any heat sink will work provided that it covers the chip
