68060 heat sink and fan recommendation

[yeko]

Can anyone recommend an 68060 heatsink/fan combo that is readily available somewhere?

thank you

I've used this - https://www.amazon.com/dp/B07N5M94NT?ref=ppx_yo2_dt_b_product_details&th=1

You can swap the fan out for a Noctua as well, but I didn't bother.

Personally I have used PC 486/ AMD heatsinks and fans with adhesive heat paste. Can be picked up off EBay for a couple of bucks.

Thank you both!

For my rev 6 060, I use one of the Amazon 40 mm heatsinks, and a 5V 40x40x20mm Noctua - at $350+ USD each, 15 bucks for protection seems reasonable. For my CheckMate case fans, 2 ball bearing 40x40x20mm seem to suffice.

I think this is a very good heatsink for the 68040/68060 CPU:

ICK PGA 18 x 18​

​

did some research and these seems to be a good choice for the double sided thermal adhesive pad:

WLFT 8926 02​

I am also in search of a nice solution. I was hoping to avoid using thermal adhesive tapes, as it will make it harder to get the heatsink off if necessary in the future. Likewise, adhesive tapes have worse thermal conductivity than thermal pastes (non-adhesive ones). The ideal solution would have a mounting mechanism for the heatsink so quality thermal paste can be used instead of adhesive tapes.

There exists some clip-on solutions, e.g. if I google BGA clip on heatsink, there are lots of offers even on mouser.com, but it is hard to judge if they would be a match for the 68060.

The closest possible solution I found is https://radianheatsinks.com/product/fa47-5/ but I did not yet get a confirmation if it fits the 68060. The chip is 47x47mm, so this one might fit, not yet sure.

Most of the DIY solutions I see on youtube are bad, e.g. lots of people use heatsinks that don't cover the entire area of the chip, or even if it covers a decent area, they have a much smaller adhesive tape like 20x20... The 68060 dissipates heat through its entire surface, so it really should be equally cooled at all points.

EDIT: Also the Wakefield-Vette’s Heat Sink Fan Series HSF-48-19-B-F (https://www.farnell.com/datasheets/2613971.pdf) seems to be a perfect fit? (but it cannot be purchased unfortunately, as far as I can tell).

When i had an 060 i used an old blower style laptop fan. Thin heatsink on the cpu and an old laptop fan to the side blowing over and obviously already quiet as made to be in an old laptop

This reduced the hight significantly so it cleared the keyboard easily

I never had much luck with cpu’s. Even running at stock speeds i had to use heatsink / fans on my 060 and my lads 030 otherwise they both crashed / frozen after some minutes

I've used this one from AliExpress >> Adda 5V 50x50x8 <<

Or his 12v counterpart & conn. him to 7V if you want it ultra quiet.
>> Adda 12v 50x50x8 <<

Nice low & fits well under drive cage of A3000.
