I have been happy with using MX4 for a while. I have used many other brands, MX4 is my most common go back to product. I use it when replacing thermal compound on console system, GPU's, and CPU's as well as 3D printers. I do enough repairs and new builds that I thought I needed more than a dinky thermal compound tube I have to replace every few months. This is good, but there is a lot. Sometimes there is a tad bit of separation in even the small tubes, so if anyone wants to avoid the mess that causes, press a small amount onto a napkin/cleaning cloth to make sure it is consistent before application. 45 grams is a lot of thermal compound though, but MX4 is surprisingly shelf stable which is why I am ok getting it in bulk. Performance wise, it is one of the best and I will admit there are some better options, but the performance difference is often miniscule until you get to liquid metal which can have its' own list of problems once you bridge over to that. This is probably the best value though as it is roughly twice to three times the cost but you get five times the amount. I got it at a $20 cost and 8grams costs around 7 dollars.
