Silver is one of the best conductors of heat, it dissipates it better than copper and aluminum. This silver epoxy contains 60% to 65% pure micronized silver and was formulated to conduct heat, not electricity. Even though it is made to not conduct electricity it can so do your best to keep it away from anything that is carrying a current. If you need to attach a heatsink or RAMsink or something of that nature to a computer component for cooling purposes you will want to have the best interface possible. Thermal tape is by far the easiest but does not perform well because its only tape, not a thermal compound. This silver epoxy should do a much better job.
This Silver Epoxy is a 2-part epoxy, you get the hardener and the resin. You also get a stick to mix the two parts together
I will be using the silver epoxy to reattach the RAMsinks on my Absolute Geforce 3 video card. I first used a screwdriver to remove the RAMsink that are on the video card, when you do this be very careful not to damage your card, be sure that you do not scratch or break anything off of it. I also took a close-up shot of the RAM, this Geforce 3 is using 3.8ns EliteMT RAM chips.
As you can see the RAMsinks are attached by the factory with thermal tape. Like I said before this stuff doesn’t work well for heat dissipation. You can also see if you look close imprints of the writing on the tape (left picture). I went ahead and took off the thermal tape and cleaned the bottoms with isopropyl alcohol (right picture).
The silver epoxy works on a 1 to 1 basis so you should have equal amounts of both the hardener and the resin to get the best results. I used a little more resin than hardener because in the future I may want to remove the RAMsinks and with less hardener it will be much easier.
Go ahead and use the mixing stick to mix both parts together. You will then want to apply a thin layer to the RAM. It shouldn’t be too thick, apply enough so it’s about the thickness of a few pieces of paper. When you apply the silver epoxy to the RAM try and not get it onto the pins, I got it on them a little and the card is fine but its best to not get it on them.
This silver epoxy performs really well as you can see from the graphs above even when the RAM was overclocked almost 100Mhz the temperatures were still below the stock speed and cooling temperatures. This stuff is really nice, I would definitely recommend this to anyone who wants to get the best results from their computer while overclocking. Now my Geforce 3 is faster than a Geforce 3 Ti 500. I would like to have seen some instructions and maybe a smaller stick with a flat surface included, however it’s not hard to figure out how to use it or to get something else to mix/apply with. Head over to ColdCPU and pick some up.
