Works great as an interface between a Raspberry Pi 4B and a passive cooling metal case.

Reviewed in the United States 🇺🇸 on September 24, 2021

Size: 20mm x 20mm x 0.5mmVerified Purchase

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.

Nicer finish than expected

Reviewed in the United States 🇺🇸 on August 19, 2018

Size: 20mm x 20mm x 1.2mmVerified Purchase

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

Only received 18 instead of 20.

Reviewed in the United States 🇺🇸 on August 11, 2019

Size: 20mm x 20mm x 0.3mmVerified Purchase

Not bad, if you only need 18.
They all measure out between .29 and .31 mm, with most of them being spot on at .3mm
All of the together measured 5.41mm, 18*.3 would be 5.4mm, so almost spot on. So, I know none were stuck together and I only received 18 of the 20.
Other than that, they seem fine. Some edges will need to be sanded down if you want them perfectly flat. But otherwise they seem good.

It's copper, it's flat, it does it's job. Great for replacing inferior thermal pads on CPU, GPU, etc.

Reviewed in the United States 🇺🇸 on October 2, 2016

Size: 20mm x 20mm x 1.0mmVerified Purchase

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.

Had heat problem on XFX 570 graphics card with heat. Added one of these under tie heat sink dropped 10 degrees
now no errors. Just make sure to put thermal paste on both sides of the spacer.

Good with Kraken G10 on AMD 7950

Reviewed in the United States 🇺🇸 on August 24, 2015

Size: 20mm x 20mm x 1.0mmVerified Purchase

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

Use esta laminilla para ponerla entre el disipador de calor y el apu de mi ps4pro ya que por alguna razon estas piezas no se juntaban y quedaba un pequeño espacio lo cual hacia que aunque pusiera pasta termica nueva esta se moviera y la consola sonaba como avion supersonico despues de poner la pqueña lamina la consola ya es muy silenciosa y para nada se recalienta estoy muy satisfecho

High thermal conductivity heatsink

Reviewed in the United Kingdom 🇬🇧 on June 15, 2016

Size: 20mm x 20mm x 1.2mmVerified Purchase

Haven't used these yet but they seem to be good quality!

My laptop kept on overheating and the fan was constantly on. I knew this was not a good sign, something had to be done.

I did some research and found that on many low to mid end laptops, the component used to cool down the processor/graphics card, is made of a low grade thermal material. Overtime the material can degrade and lose the ability to cool down the CPU adequately, which in turn causes the overheating.

Copper has a high thermal conductivity which means it is very effective in drawing out the heat from where needed. The manufacturer claims the copper shims have a much higher thermal conductivity than ordinary copper.
