Would putting a heatsink on the back end of my maxi-jet where it has that epoxy looking stuff help keep it cool at all? I'll have an 80mm fan blowing on it.

I added some thermal goop under it to help conduct the heat better, and used several wraps of electrical tape to tension the copper until the JBWeld on the overlapped section dried. Quite a tight fit.
I then hammered the extra 1/4" of sheeting over on each end, to seal in copper pieces that I'd cut to fit.
It felt cooler, but I'd never measured it. It surely wasn't hot enough to burn or anything.
I can't vouch for how it may or may not have helped longevity, when the outdoor temps here rose, I switched back to using my basement heatercore...don't know how you ambient cooling guys can stand it
*And by the way, if you can touch your pump, and it feels hot, then it is in fact conducting heat through the epoxy and plastics, and is NOT dumping all the heat into the water. Only a submerged pump can do that...
Diggrr said:Nah, buddy.
I used electrical tape just for it's springiness. The copper wrapped around the pump with a 1/2" of overlap to spare, and a 1/4" at each end. In the 1/2" overlap area, I placed JBWeld to secure the two ends together, and the tape held it tight while the epoxy cured, and then was removed.
I used copper because it was handy, and it absorbs and releases heat to air better than other metals (as it does so well in heatsinks), it's not insulating. Admittedly the copper I used was fairly thin, but so is a WW base. I didn't need it to spread heat out, but to transfer it to the air better than the pump's plastic can.
The airflow in the case took care of the rest.
Add a little wire for grounding, and the EMI was no longer a problem either.

I'm not under any protection that I know of, so feel free.
Where was jaydee's post?..didn't see it.
tehnull said:Greenman are you saying that if I epoxy a heatsink to the epoxy backing on my pump that it won't lower the temperature of the pump at all and if so what proof do you have to back this up?
Epoxy, with its W/cm-K of .002, and even thermally conductive epoxy, with its W/cm-K of .008, are considered thermal insulators, not thermal conductors.tehnull said:So you're saying that epoxy doesn't conduct heat?
no I am not.So you're saying that epoxy doesn't conduct heat?
