Low power UPS and GPU temp control

Hi guys, i was wondering, my GPU cards when in high load go around 70-75º which i've read isn't bad although a little high than the ideal.

My question arises from the fact that I have a low power UPS which begins to sound when my GPU's go to a high load (which i've searched that it occurs when the UPS is too low for my PSU when the PC is demanding more energy) and it's at the same time that my cards go to the 70-75° range (generally is around 65-68° under normal load).

So i was wondering, since my low UPS isn't giving the required energy when under high load, could that be affecting the fan performance of my GPUs too?

Hope someone can clarify that! Thanks for the help!

I don't know if it's an online UPS, but that doesn't happens when it's on battery but on electricity. I have read that it seems that since the UPS outputs a steady and constant current (and can't go higher or lower than that), when the PC requires more energy it doesn't receive it since that would mean higher energy and the UPS can't change his voltage.

So, when my PC demands more energy as so to make more load for GPU, CPU, etc. the UPS begins depleting the battery too (and starts to sound as a consequence) as to give the energy required for the PC. I was wondering that maybe that could affect my GPU's performance to maintain a more steady temp under load and not rise up to 70-75°.

It is an Omega DV-800 UPS. I still have to buy a new UPS, i was thinking maybe an APC Back-Pro of 1200 or 1500 VA.

Thanks man! I also was thinking about that one.
