Listed at 40.29 USD. CS LABS Thermal Paste & pad Replacement Set K5-PRO & K4-PRO for iPhone, iMac PS4 Features K5-PRO is a high quality gummy thermal paste designed for use on memory chips and GPUs of various computers including iPhone, PS4, PS3, Apple iMac video boards. This is the only commercially available product at the moment that can replace the gummy thermal paste that is originally used by Apple. K5-PRO can replace soft thermal pads that are used on computers (up to 3mm thick) K5-PRO has thermal conductivity K>5,3 W/m.K * (at least 3 times higher than common thermal pads that are used on computers and commercial electronics) .K5-PRO is applied very easily directly on the component and has no electrical conductivity. It can be heated up to 250 degrees (Celsius) and has a long operational life time (practically infinite after the installation) K4-PRO is a high quality thermal paste designed for use on computer BGA components (GPU, CPU, etc).K4-PRO is a very low viscosity thermal paste (especially when heated during the fist use). It will cover all the invisible gaps between the component and the heatsink without creating a film of paste like most low cost thermal pastes. K4-PRO has thermal conductivity K>4,6 W/m.K * (3 times higher than common thermal pastes that are used on computers and commercial electronics).K4-PRO is applied very easily directly on the component and has no electrical conductivity. It can be heated up to 220 degrees (Celsius) and has a long operational life time (practically infinite) * Computer Systems matterials science laboratory testing : Method using a comparative technique (P. Karydopoulos, P. Frantzis, N. Karagiannis MSAIJ 2014) Description This offer is for a set of thermal pastes which can be used to replace both thermal pastes and thermal pads on laptops, desktops and gamestations like iPhone Apple iMac, Apple Macbook, Sony Playstation 3, PS4, PS3, Microsoft XBOX, Acer Aspire, Asus, Dell etc. The set includes 7g of low viscosity thermal paste K4 PRO(for use instead of original thermal paste on the CPU and other components) and 20g (2x10g)of viscous thermal paste K5 PRO (for use instead of thermal pads on memory chips and other components). Set includes: 7g of high thermal conductivity K4 PRO thermal paste in syringe 20g of viscous thermal paste for thermal pad replacement K5 PRO Expiration date: No expiration date (new formula). Infinite storage / service life. Protect from frost and dust. You can see our instructions video in our youtube page " ComputerSystemsGR ".K4-PRO 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 Europian Union. These two products are designed to reduce the chances of video board failure for reasons related to overheating. When you should replace the thermal paste / pads in your computer: Thermal paste and thermal pads should be replaced every time that the heat sink is removed (for cleaning, upgrade or other maintenance). Replacing the thermal pads and the gummy thermal paste that is used by Apple on the memory chips is very important if the heat sink is removed because if you reuse the same thermal pads or paste the heat sink is impossible to fit perfectly again and the component will be overheated and will fail soon. If your computer is overheated or turns off after a few hours of use. In this case the entire heatsink system must be cleaned immediately and all thermal paste and thermal pads must be replaced.
