Supplied in a generous 500g package, it offers over 2500 precise applications. Its low viscosity ensures perfect heatsink contact without electrical conductivity risks, while its EU-based production guarantees premium quality and reliability for long-term thermal management. ## Description K4-PRO low viscosity thermal paste is developed and produced by Computer Systems laboratories research department. This product was developed as part of Computer Systems BGA rework research project with the support of Greece and the European Union. This product is designed to reduce the chances of BGA component failure for reasons related to overheating.This listing is offering 500g of K4-PRO thermal paste. On each application less than 0.2g of K4-PRO is needed so this quantity should be enough for more than 2500 applications!!! You can see our application instructions video on our youtube page "" ComputerSystemsGR "".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 heat sink system must be cleaned immediately and all thermal paste and thermal pads must be replaced. ## Features - K4-PRO is a high quality thermal paste designed for use on computer BGA components (GPU, CPU, etc). - K4-PRO has thermal conductivity K>4,6 W/m.K (3 times higher than common thermal pastes that are used on computers and comercial electronics) Computer Systems materials science laboratory testing : Method using a comparative technique (P. Karydopoulos, P. Frantzis, N. Karagiannis MSAIJ 2014) - K4-PRO is applied very easily directly on the component and has no electrical conductivity. It can be heated up to 220 degrees (Celcium) and has a long operational life time (practically infinite) - K4-PRO is produced in EU (Thessaloniki, Greece) with matterials 100% from EU. This is not a low cost Chinese product - K4-PRO is a very low viscosity thermal paste (especially when heated during firs use). It will cover the invisible gaps between heatsink and component perfectly. ## Technical Specifications | Specification | Value | |---------------|-------| | Manufacturer | Computer Systems Laboratories | | Part number | K4-500g-uk-FBA | | Item Weight | 500 g | | Product Dimensions | 8.7 x 8.7 x 6.7 cm; 500 g | | Item model number | K4 500g | | Wattage | 4.6 watts | | Item Package Quantity | 1 | | Noise Level | 14 dB | | Plug profile | PCB Mount | | Batteries included? | No | | Batteries Required? | No | ## Product Details - **Brand:** COMPUTERSYSTEMS REPAIR SERVICES DATA RECOVERY - **Cooler heat sink material:** Aluminium - **Cooler heatsink compatibility:** Computer components (CPU, GPU, etc.) - **Item weight:** 500 Grams - **Mounting type:** PCB Mount ## Images ![K4-PRO 500g high thermal conductivity thermal paste K 4,6 W/m.K for computer heatsinks Compatible with laptops, Apple MacBook & iMac - Image 1](https://m.media-amazon.com/images/I/71-c8VEgQfL.jpg) ![K4-PRO 500g high thermal conductivity thermal paste K 4,6 W/m.K for computer heatsinks Compatible with laptops, Apple MacBook & iMac - Image 2](https://m.media-amazon.com/images/I/71SjmZWXfbL.jpg) ![K4-PRO 500g high thermal conductivity thermal paste K 4,6 W/m.K for computer heatsinks Compatible with laptops, Apple MacBook & iMac - Image 3](https://m.media-amazon.com/images/I/71tBxMtlQZL.jpg) ![K4-PRO 500g high thermal conductivity thermal paste K 4,6 W/m.K for computer heatsinks Compatible with laptops, Apple MacBook & iMac - Image 4](https://m.media-amazon.com/images/I/71+0Fe7LmXL.jpg) ![K4-PRO 500g high thermal conductivity thermal paste K 4,6 W/m.K for computer heatsinks Compatible with laptops, Apple MacBook & iMac - Image 5](https://m.media-amazon.com/images/I/71kAoh99tnL.jpg) ## Frequently Bought Together - K4-PRO 500g high Thermal Conductivity Thermal Paste K 4,6 W/m.K for Computer heatsinks Ideal for laptops and Apple iMac, CSGR - 4 Pack 13W/m.K Thermal Pads, 100 x 100mm 0.5mm+1mm+1.5mm+2mm Silicone Cooling Pad Non Conductive Heat Resistance Extreme Odyssey Cover with Dual Self-Adhesive Films for PC Laptop PS4 - ARCTIC MX-6 (8 g) - Ultimate Performance Thermal Paste for CPU, Consoles, Graphics Cards, laptops, Very high Thermal Conductivity, Long Durability, Non-Conductive --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/49537371-k4-pro-500g-high-thermal-conductivity-thermal-paste-k-4](https://www.desertcart.tn/products/49537371-k4-pro-500g-high-thermal-conductivity-thermal-paste-k-4) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-05-29*
