RS PRO Silicone Thermal Grease, 3.9W/m·K

Use this thermal grease from RS PRO if you need to maintain an efficient flow of heat through your equipment. Applying it between surfaces fills up any gaps to prevent the air from acting as insulation and its own high level of thermal conductivity allows heat to dissipate more easily.
The product is also known as central processing unit (CPU) grease or heat sink paste, as it's commonly used between components in electronics systems. Its resistivity will keep your equipment safe and reliable, by preventing electrical current from being transferred.
This thermal paste has excellent stability and won't harden, so your maintenance time will be reduced. It's made from silicone, which gives it a broad operating temperature range, making it suitable for the most demanding environments. Besides consumer and industrial electronics, it can be used in power supplies and automotive engines.
