When I first started building computers there were plenty of thermal pastes on the market, but the only real option for the time was Arctic Silver 5. There were a few downsides to Arctic Silver though – since it is a silver based compound it is electronically conductive and after a year it starts to solidify, decreasing the thermal performance and making it stick like glue to the heatsink base. I know I am not the only person that has used Arctic Silver 5 and pulled the processor out of the socket when removing the cooler.
Thermal pastes might not be the sexiest product on the market – sure it would be more exciting to examine a new water cooling block, AIO cooler, or massive dual fin-stack heatsink, but thermal pastes have an important role in cooling as well – without them even the best heatsink would fail to cool a processor efficiently.
First let’s look at the reason behind the need for thermal paste. All metals regardless of how smooth have microscopic air-gaps present due to the imperfections of even the flattest and smoothest surfaces of the metal. These air gaps need to be filled in order to ensure the hot air can be transferred from the core to the heatsink. Without it, the heat from the core would get caught in the air pockets and not be able to transfer to the cooler. Of course this would lead to the processor overheating even if you are using the best heatsinks on the market.
For these reasons overclockers are always looking for the best thermal paste on the market and there have been some major advancements over the last few years. As an example of this we need look no further than JunPus, who has developed Nano diamond powder and silicone fluids to create multiple thermal pastes that have high chemical stability, are non-corrosive, non-conductive and doesn’t solidify in a short period of time.
In this review we are going to be looking at two thermal pastes from JunPus – JP-Dx1 and JP-D9000, which cost $10.95 and $11.95 respectively.
