I connected 2 heatsinks that I had to a power supply that gets really hot. This works really well, but it's kind of weird...

<p>i read somewhere that toothpaste work pretty well as the goop they use to thermally connect the sinks to electronics, might be worth a shot to increase the heat dissipation:)</p>
<p>Thanks for the tip, But toothpaste would last only a couple hours because it would dry and then stop conducting, But right now what I have is good enough, If I ever find that this isn't good enough I'll probably just replace the power supply...</p>
<p>no not as a evaporation coolant, more like solder. there are gaps(however small) between the heat sink and the components, the paste helps transfer the heat to the sink. by conduction, not evaporation.</p>
<p>Are you thinking to melt solder onto the heatsink, Let it cool down, then attach the power supply?</p>
<p>haha no i mean that the toothpast would act like solder, by transfering the heat by conduction into the heatsink, wich loses its heat by radiation: <a href="http://www.spaceflight.esa.int/impress/text/education/Heat%20Transfer/Question_Heat_Transfer_Introduction_01.html." rel="nofollow">http://www.spaceflight.esa.int/impress/text/educat...</a> </p><p>still air is a pretty good insulator(the airpockets between your component and heatsink) the thermal paste used in between a component and a heatsink helps remove this insulation.</p>
