Question/concern: after repasting, GPU drawing more power, but running cooler at same clock speeds.
Background: on the never-ending quest for cooler temps with just air cooling, I decided to repaste my Sapphire RX580 Nitro+ SE with MX4. The card has always run at GPU speed of 1430MHz and a memory speed of 2100MHz and never thermal throttled. The first repaste attempt saw higher temps, so when I pulled off the heat sink, it was obvious why. One corner was bare, probably due to uneven tightening of the cold plate. But temps never got above 80C, which was a bit relieving. Anyway, I cleaned it up and repasted with MX4 again, using a tad more paste and paying attention to how I tightened the screws. This time, my temps are a few degrees lower (even lower than the stock paste). After running Heaven for 30 minutes and never getting above 66C, I decided to throw a Doom session at it. Again, my temps were fine (and clock speeds were at those mentioned), but it was drawing more power.
I say this because I have my PC running off an UPS. If I draw more power than the UPS' rating, it emits a steady tone until the power draw falls. This usually happens only momentarily when I print. While playing Doom last night, my UPS was going crazy emitting power draw tones, especially in scenes with a lot of activity. It has never done this, and I primarily play Doom or F1 2018, sometimes for hours.
I know that repasting can sometimes allow a card to boost higher, but mine always ran at the max boost clock of 1430. I also have not applied an OC. Does it make sense that the card would draw more power? Sorry if I'm missing something obvious here.
