how to make thermal pads

[monu_08]

hi guys i want to know that my gtx 570 need to replace thermal pad so i just thinking about to buy one but they are not available in my country so i just think about to use this method with my thermal paste to make thermal pads here

Thermal paste is a better heat conductor than air.
But, it is not nearly as good as metal.

If there is a gap that must be filled, consider using a thin metal shim in the space. Copper would be best(silver is actually) or next would be aluminum. You would still want to use thermal paste. The purpose of paste is to fill in any air pits in the mating surfaces.

i dont have any copper shim or aluminium one i just thinking about to make myself own thermal pads but i dont know how to make it there is a gap bw in my gtx 570 vram and heatsink to so how can i make thermal pads sohuld cotton guaze with thermal paste on it will work

Fortunately, vram does not get all that hot.
You could cut up some cloth into vram sized squares and soak them with a good conducting paste. Gauze tends to be thin, but that is good if it is a thin gap. Use thicker cloth or fold it over if the gap is large.

so will cotton guaze or cotton cloth with thermal paste will work on vram really

its not working cotton guaze with thermal paste is not getting cool my vram help me

There are a few things to know about thermal compounds and thermal pads that might be of help.
■Thermal pads are better at conducting heat than thermal paste/compound - in some cases up to three times better but at ~10x the cost per application. It is the cost of pads that make paste more popular on CPU's and other places that may get replaced more often
■ Thermal paste becomes less effective as the application of it gets thicker - the primary reason you always want to apply the thinnest layer possible on any surface
So here's where the method you are attempting 'breaks down'. 1) you have cloth in your compound, cloth is one of the worst conductors of heat there is (why we use it to keep cold air off us). Almost any material would be a better filler than cloth (except styrofoam, rubber or some plastics). 2) Too thick of application for the product to perform well.
Here is what I would suggest sans putting in new thermal pads. Use aluminum foil to make a pad, layering on top of itself with thermal compound between layers - very thin TIM layers, you're simply removing air between the layers of foil. Or, an option (I don't think is as good) would be to fill the paste with as much diamond powder as possible (50,000 grit minimum, 100,000 is better but harder to find) without drying it out too much and just use paste. Diamond powder can be sourced through most lapidary suppliers and is not too expensive (~$1/carat). I should point out here that while silver is the best heat conducting metal, diamond is the best heat conductor known.
Hope you can get somewhere with that info

sir will aluminum foil layering them bw thermal paste will help me to make thermal pads because currently i m using double side tape which is act as an insulator i m sure that the aluminum foil will work but some say it will conduct electricity🙁 too so it will be problem to use aluminum foil bw circuit of gpu do u have any suggestion how can i resolve this sir please help me i m n deep trouble may god bless u for answering my question help me sir🙁

While aluminum does conduct electricity, the components you should be placing the pads on are electrically insulated so the possibility of shorting caused by the aluminum should be minimal. You will want to make sure you cut your pads to exact size so they do not make contact with any exposed connections and take every precaution against touching one component to another but I would think it would be do-able.
I did however forget to include my standard warning that I would want to use the proper material here (thermal pads) and that I wouldn't recommend either alternative approach for any purpose other than emergency (and temporary) use.

Here's my personal take for a possible option, since thermal pads are expensive but, they are also rather inexpensive to ship - I would look to a reputable retailer with int'l shipping, bite the bullet (so to speak) on a one time purchase for a full thermal pad (quite expensive at $60-$300 depending on thermal conductivity and thickness), use what I needed and look to sell the remainder. Conversely, you could simply purchase the right size pad(s) for quite a bit less (~$15-$30) and have them shipped

will this pad will fit in my gtx 570 http://www.amazon.com/High-Performance-Thermal-Pad-Playstation-3/dp/B005J730WO/ref=sr_1_3?ie=UTF8&qid=1365778088&sr=8-3&keywords=thermal+pad

I would think it would work if cut down to size (seems a little big but I'm not sure) - I think it would be a major improvement over the alternative methods. Looking around, I found a few places that offer free samples like this http://intermark-usa.com/products/thermal-pads-and-thermal-management/thermal-pads-qoolite-th-standard-silicone-base-imth70-series/ maybe one or two free samples could take care of your graphics VRM (I have no clue what size a free sample might be)
