Do VRM need cooling?

I saw some posts from people who watercooled their GPUs with CPU watercoolers and they are only cooling the GPU with it and the rest of the PCB is entirely naked with no heatsink or fan. And at this point i am wondering if it would damage the VRM in the long run or overheat it without any kind of cooling. (sorry if it´s a dumb question but i want some clarity)

Those link´s shows a HD6xxx or HD7xxxx GPU with a CPU watercooler and the PCB has no heatsink or fans on it
