Thermal paste is a crucial component of a PC’s cooling system. It minimizes minuscule holes and inconsistencies between the CPU’s integrated heat spreader (IHS) and the cooler’s surface to ensure optimal heat transfer. However, choosing the right product among a dizzying array of choices can be tricky, especially for an inexperienced user.
There are many different thermal compounds on the market, but choosing one that is non-conductive is important to avoid short circuits. This is especially true when working with a liquid metal-based thermal paste, as spilling it on any electrically-conductive component can result in damage and shorting. The best choice is a carbon-based or ceramic-based paste, as these do not have any metallic particles that can cause electrical conductivity.
The Noctua NT-H1 is the best option on the market for those who need a high-performance, premium-grade thermal paste. It has excellent heat dissipation and is highly recommended for overclockers who demand the best performance from their systems. It has an impressive thermal conductivity of 8.5 W/mK and contains no electrically conductive particles, so it is safe to use on both your GPU and CPU.
The Arctic MX-4 is another top-rated thermal paste for both CPU and GPU applications. It has great performance, is easy to apply and has a non-conductive formula that will prevent short circuits and other electrical issues. It is also a great value for your money as it is available at a very affordable price.
