Thermal compound on GPU?

[Kgx Pnqvhm]

While reading up on heat issues, I came across the issue that the thermal compound between the CPU and heat sink will go bad over time, and should be replaced periodically.

And that this applies to the GPU, also.

Since people here are likely to be running GPUs nonstop, has anyone had the practice of periodically re-applying thermal paste to their GPUs?
