Summary: We know that mayonnaise is a good emergency thermal compound, but does it keep working after a few days? Let’s find out!

Here is a snippet: "Back in 2011, we tested mayonnaise as a thermal interface between the CPU and the base of the cooler. Amazingly, it worked nicely, proving to be, at least in a short term, a better thermal compound than several well-known commercial products. But, at the time, we could not determine how long it would continue to work before a degradation in performance was noted. This time around, we ran a long-term test to determine if mayonnaise can last as a thermal compound."
