And this copper heat sink solve thermal problems caused by frequent crashes laptop, etc Package included: 20 pcs Thermal Conductive Copper Shims 15mm x 15mm x 0.8mm

Review: Used these to lower my 3090 FE memory temperatures - I have a waterblock on my 3090 FE, and I also have a ram waterblock mounted to the backplate to help cool the rear memory. My block and backplate call for 2mm thermal pads in between the memory chips and the backplate. I ended up substituting those pads for 1mm pads and 1mm copper shims. My memory temperatures are now 15C lower than with the stock pads. Some of the edges were rough, but a quick pass on some 600 grit made they perfectly flat. Thickness was also pretty dead on at 1mm. Highly recommended!
Review: Seems thinner than specified - The parts I ordered were 1.0mm thick. I do not have a measuring tool but they measured less than 1mm beside a measuring tape. IMO these were 0.8mm thick, noticeable. I had to use extra thermal paste to fill the gap and was slightly disappointed. Works better than a thermal tape for transferring heat! Would buy again, though I might buy thicker than advertised

### ⭐⭐⭐⭐⭐ Used these to lower my 3090 FE memory temperatures
*by N***A on March 2, 2021*

I have a waterblock on my 3090 FE, and I also have a ram waterblock mounted to the backplate to help cool the rear memory.

### ⭐⭐⭐⭐ Seems thinner than specified
*by R***R on November 9, 2019*

The parts I ordered were 1.0mm thick. I do not have a measuring tool but they measured less than 1mm beside a measuring tape. IMO these were 0.8mm thick, noticeable. I had to use extra thermal paste to fill the gap and was slightly disappointed. Works better than a thermal tape for transferring heat! Would buy again, though I might buy thicker than advertised

### ⭐⭐⭐⭐⭐ decent finish . not as polished as I was hoping for
*by D***P on July 26, 2016*

Never got around to using these but I figured since it came as advertised. pretty good finish on these. For those OCD types then yeah you can lap it a bit more for a better finish. but otherwise it's a good enough finish for a quick install
