of course it does - less voltage => more power headroom and less overall power, less heat dissipated => more thermal headroom. If the silicon doesn't need the voltage, more voltage is only harmful. I can run my skylake alike laptop at -170mV offset (which is borderline golden chip), stable at prime 95 and whatnot. Prime95 runs below 70C.
