Review on Cosmos Copper Cooling Heatsinks Cooler by Samuel Bowen

It's a heatsink, it does what it's supposed to do. I examined them, they are definitely solid copper. I didn't use the included double sided tape, but used Sywon Professional Thermal Adhesive Conductive Tape, which can be found here at Revain. Buy good stuff if you can instead of using the included cheap plain double sided tape, it really makes a difference for heat transfer and sticks much better, heatsinks WILL NOT move. Makes great heatsinks for things like this Raspberry Pi. I use them for Phat XBOX 360 memory chips and bridge chips. Helps cool the RAM down a bit.
