IC Chipset GPU CPU Thermal Heatsink Copper Pad Shim Size 20 x 20 x 0.3mm Pack of 20pcs

Bought the 1mm for modding my GPU.Before I got these, after about an hour of gaming it would hit temps at around 85°C - 92°C. These bad boys dropped temps down 15°C - 20°C.Worked perfect.

Works great, extremely quick shipping, perfect quality: no blips or blemishes on the surface of any of the shims. Works great with my r9 280 that im water cooling with a NZXT Kraken G10 because the block was not making contact with the GPU die. These nifty little shims have tons of other applications such as extra laptop cooling. You can use these for everything! And at this price, I'll buy these things until the day I die. You wont go wrong with these wonderful little things!

I used these to improve the sensitivity on a stepmania dance pad where I really had to stomp on the arrows as hard as I could to get the presses to register properly. It was driving me nuts. I applied about nine of these between each of the contacts with some conductive double-sided tape.Doing this is commonly referred to as a penny mod, and you can do it for literally a few cents if you want to do it that way, but this seemed a little more robust. With these in place the difference is night and day, it's so much easier to use now.

Good Quality for the cost

These shims are specifically the thickness the makes of my Raspberry Pi's case said to use. Actually , they said to use the enclosed thermal tape, and that pretty much didn't do anything positive for heat disappation. The RPI4 processor reported an idle temperature of 50°C. Using these with thermal grease, the idle temp hovers around 34°C. My Pi is overclocked substantially, and even loaded showing a 4K video, I'm still not showing temps over 55°C.

Product as described and works great, just double-check the exact thickness that you need before ordering. I have found that I can cut the pieces to a customized size using a vice (use wood shims to protect the copper surface) and a hacksaw. The rough edges are easily smoothed over using a medium course flat file / knife sharpener. Don't try to cut to size using tin snips or the like or you will bend your piece and you want it to remain perfectly flat. Wash your hands before installing and clean the copper well with 91% isopropyl alcohol and a microfiber cloth.. Combine with a high-quality thermal paste.

Works like a champ. Got this because it fits between my AMD 7950 and Corsair H55 cooler (I have a Kraken G10 setup and certain AMD cards have a frame of sorts around the gpu die, requiring a copper shim). Since this is a pack of like 12 or whatever, I'll be using them for all my future gpu cooling needs!If it matters to you, thsee shims are exactly the dimensions of the 9700 series AMD gpu's so if you are rough with the cooler you're going to wiggle it around and potentially scoot it off the GPU. Also, be careful not to use too much thermal paste :-D

I got these to help with cooling down my RAM and Super I/O chip. They come finished much better than expected, so I just had to use my polish to get any extra dirt and tarnish off of the side I glued. I haven't tested how much they help with the heat since my laptop still has pads coming in the mail. My Super I/O chip has zero airflow so I actually cut one shim several times about 2mm down all the way around and then attached it to another shim that was then attached to the chip. Just to give it more surface area for heat to dissipate. I just used 2 shims for each RAM card because they get airflow.Will update after I get the other parts on the heat dissipation the do or do not help with
