Maybe I'm exagerating but this 060, latest mask, is gonna be working at 80Mhz :)
It's for an MKII, and since it's gonna be used on an A4000T for now, it's gonna be hanging down vertically from the CPU card. Don't think cooling past will be enouph to secure it.
What else should be used ? Don't like clips, but is SuperGlue gonna be enouph to conduct heat to the heatsink, even if it's just 4 drops on each corner ...
What if I later want to take off the heatsink and use another one ? SuperGlue is probably hard to take off...
....
Suggestions welcome...

Somebody posted this a while back. I haven't used it myself, but it seems a lot better than super glue.

I've used the arctic silver thermal adhesive. It's very good, but don't expect to get the heatsink off again once it's set!
-
Don't use super glue! It has next to no thermal transfer properties, and is too hard to get off. You'll be sorry...
-
I've used just two drops of superglue (opposite corners obviously) and a spot of thermal paste in the middle - can even be removed by edging a sharp blade between the CPU and the heatsink (probably depends on your flavor of superglue though).
-
I guess the missed heat conductivity on those 2 drops is not that much. And it's less expensive. The artic silver thermal adhesive on the other hand probably dissipates heat better and I don't mind if it's permanent cause in this case it would be silly to have the latest mask 060 and not clock it properly! I'm probably gonna use it with a copper heatsink and use a silent Silenx fan on it :)

Acetone dissolves the arctic silver glue.
Great for removing sticky heatsinks.

I used a big dollop of glue in the middle of my Apollo 1240 accelerator and stuck a bloody big fan on there when the original wires became detached from the card (i didnt know it was a stepper motor!!). It worked really well. But that was an 040 at 28Mhz...
It`s going to be a nightmare now that i want to go back to basics and put it in an original A1200.

I would always recommend trying to find a heatsink with a retention clip rather than using glue.
But if you have to, use a glue which is rated for heatsinks OR just a few tiny blobs in the corners.
Always use the right amount of thermal compound. Use too much and it's conductive properties are reduced.

I used the super-glue trick on my CyberVisionPPC. FYI that graphics chip gets super hot, you could easely get a blister on your finger touching it when its running.
The super-glue trick worked great on a Zalman heatsink, but when I removed the card the heatsink just fell off the graphics chip! So it is not a permanent dependable solution in the long run IMHO.

"Acetone dissolves the arctic silver glue."
Awesome.
Well, given all the info above I've decided and ordered the artic silver glue thing...
-
I've had good results using a mix 50% arctic silver (the trasfer paste not the glue) and 50% epoxy resin.
Only done this on Sun Enterprise boards where the retention clips break when the machines are moved (probably roughly).

I'm using common thermal glue pads.Perfect fit, don't come loose after some time and are extractable.
-
Last time I cautioned about using Super Glue on computers, I was shot down... but here goes (again) ....
Super glue, of course isn't electrically conductive. I'd worry that the vapors could spread, and cause contact problems. I've had super glue ruin DC motors this way. (in model trains) I know some people have used Super Glue successfully to secure heatsinks, but if it were my Amiga, I wouldn't....
My 2 kopeks ....

Can't stand 'Super Glue'... always use Crazy Glue. Big difference in how they set (or not). I use Crazy Glue all_the_time to mount heat sinks yanked off of PeeCee video cards to the game roms of Gottlieb System 1 pinball machines. lol Works like a charm, looks cool, doesn't slide off and saves the life of a CPU board. You know a PeeCee is worthless when the heatskinks off their video cards are more valuable than the entire system ;-)
