There are different opinions on how often thermal paste should be replaced. Generally, it's said to last between 2-3 years, but this can vary depending on heat and usage habits. Is it better to replace it before performance loss starts due to temperature increases, or wait until signs of overheating appear?

Thanks for opening such a useful topic. So, which hardware have you replaced thermal paste on?
We can compare thermal paste to vehicle lubricant. Just like in lubrication systems, thermal paste loses performance as it dries out. For example, if you don’t change the oil in a car engine on time, clogs form. The same logic applies to thermal paste—it dries up over time and slows down heat transfer. You can get an idea of its condition using a temperature sensor, similar to how oil pressure sensors work in vehicles.
While ISO 228 sets standards for torque wrenches, there’s no official "lifespan standard" for thermal paste. However, in practice, most users prefer to check it every 1-2 years. If you notice overheating or performance drops, it’s best to act, just like with an oil change. Waiting for "symptoms of suffering" to appear can lead to hardware damage and unnecessary stress.
