This offer is for a set of thermal pastes which can be used to replace both thermal pastes and thermal pads on laptops, desktops, cryptocurrency video board miners and gamestations compatible with iPhone Apple iMac, Apple Macbook, Sony Playstation 3, PS4, Microsoft XBOX, etc. The set includes 3g of highest thermal conductivity KRYO33 paste and 10g of viscous thermal paste K5 PRO (for use instead of thermal pads on memory chips and other components). You can see our instructions videos in our youtube page " ComputerSystemsGR ".KRYO33 and K5-PRO are developed and produced by Computer Systems laboratories research team. These products were developed as part of our BGA rework research project with the support of Greece and European Union. With thermal conductivity over 13W/m.k KRYO33 is so effective not only because it's ingredients have very high thermal conductivity but also because their particles have the minimum possible size. With particle size ranging at 30nm KRYO33 behaves like viscous liquid while it is actually a cream of solid but very small particles. For this reason we know for sure that KRO33 have the maximum thermal conductivity that any thermal paste can reach without using electrical conductive materials (like metals). KRYO33 can be perfectly combined with K5 PRO since both consist of very small particles. This way they allow heat sink to reach minimum possible distance from warm component even if heat sink is not flat at all areas. At the same time all gaps between heat sink and component, even the invisible gaps on metal surface, are filled with thermal conductive materials. Key features Zero electric conductivity Can be applied on all surfaces of electronic components and PCBs even on aluminum Color Gray Specific gravity 2,9 (30% lower than competitive products so less weight is needed for same surface) Certification Reach, ROHS, CE Electric, CSGR.
