    Its thermal paste. I have no complaints. It's expensive, but the convenience of going to Best Buy and picking it up is great. I have used mx-5 and noctua's paste. See no downsides or disadvantages to Corsair branded paste.

    Used on a 5 year old laptop, replacing thermal paste on any device that old will usually lead to good temperature improvements, but with this case at least it lead to a cooler CPU that was also able to draw substantially more power during a benchmark and the GPU was about 8 degrees C cooler while also pulling a few watts more power on average. Laptop specs: i7-8750h and 1060
