Miners usually undervolt the GPUs to mine at peak efficiency, not peak performance and power consumption. Since chip wear correlates with power usage and heat production, GPU usage for mining is actually much less taxing for the hardware than typical gaming use with its frequent overclocking and rapid alterations between low and maximum power use.

It is also important to realize the wear on the chips is relevant on the order of 100 years. What fails on the order of 1-5 years are capacitors and insulation on the power supply coil windings and fan motor windings, but the latter only sometimes.

Capacitors notably derate exponentially with increasing temperature as do many other things.
