So you just went out and bought the top-of-the-line CPU cooler, and a whole bunch of case fans to keep your processor running nice and cool. At this point it’s pretty tempting to just slap the CPU cooler on exactly as it came and call it a day. However, there’s one thing that seems to be overlooked a lot, and that is thermal paste. The paste that typically comes with your cooler will do the job and net you decent temperatures. But why would you skip out on the chance for cooler temps without modifying your cooler? “Aftermarket” thermal paste will typically yield a temperature drop of 5 degrees or more over stock paste.Today, we have Tuniq’s offering in the enthusiast thermal paste market, the Tuniq TX-4. Tuniq has improved on its TX-3 formula of thermal grease, yielding even better performance. As per its lineage, TX-4 is a thick and viscous, non-conductive thermal grease. The TX-4 iteration boasts a lower thermal resistance, easy-application TIM spreader, and longer life. Let's see how it fares in the fairly exclusive enthusiast Thermal Interface Material market.
