Under Volting and negative Power Limit

[Born_2_Kill_83]

So I'm trying to reduce my temps of my CF290X setup due to some throttling, I have left the clock speeds at stock 1030/1250 and I have reduced my volts by -25mV, this seems to be as far as I can go with this before the desktop or gaming gets unstable.

Reducing by -25mV has only saved me a few degrees C, however I have noticed if I reduce the "Power Limit" to -50 I save another 15C on top, gaming seems to be stable so far.

Will reducing the power limit cause me any issues I should know about? My max temps on the top card are now under 80c which I'm happy with.

Scrap some of that just crashed at -50, now trying -25

Decreasing the power limit will throttle the card's performance.
