Alphacool 17427 GPU RAM Copper Heatsinks 14 x 14 mm - Pack of 10 Air Cooling Passive Cooler

Late review but product overall very satisfied the copper heat sink's are good for high thermal conductivity allows heat to pass through it quickly. Project I've been looking into was to change the stock thermal paste for my PS4 Original (Matte black) turns out I could buy Thermal Pads for the memory chips if thats what's it called any ways I cut a hold on top of my PS4 shell because the heat sink wasn't going to shut properly, Each chip has it's own Thermal pads an heat sink an I've read that copper is better than aluminum for heat to pass through quickly, But this project help my PS4 from sounding like a jet engine when playing long hours an for those who are wondering I clean my console every 1-2 weeks also I use arctic silver 5 Thermal compound for the cpu chip very good quality paste. *Sony Thermal paste dried up very quickly an if I didn't looked up on youtube my PS4 would've crash or possibly break due to the over heating. Anyways well worth it!

Son unos bloques maravillosos y super útiles para aquello de reducir la temperatura en las memorias RAM de la tarjeta gráfica. Tiene un funcionamiento más estable usando overclock mi 5700XT

Habe diese Kühlkörper aus reinem Kupfer zur Kühlung von South-Bridge und M.2 SSD verwendet. Zur Kühlung von GPU ist eine freche Behauptung des Verkäufers - es wird niemals dafür reichen. Zusätzlichen selbstklebende Thermal-pads oder anderer Art Wärmeleitkleber sind zu empfehlen.

El producto no cumple las expectativas y además el vendedor no nos atendió correctamente

I was having an issue with a Nvidia (Palit) 1080Ti overheating. I used two sets of these copper fins to form a (fan sized) square on the top-plate. I then Rested a silent fan (blowing down) on top. I was expecting noore than a 2C drop but the temperature actually fell by almost 5 Centigrade. That's almost as good as water cooling but way cheaper, silent and uses less power! I think these may sell out!
