For you folks who replaced your fans, be aware that with the new firmware that increases hash-rate, the chip temperature will also increase.  Might wanna keep any eye to ensure you're getting adequate cooling.

Can confirm utilization increases in my end were less than 75W on two B3s @240V.
(Using one AWP for two miners)

SP120 LEDs still doing the job at 52C in a 25C room.

Wat was the total watts used per miner?

363 watts right now. Was at 338 before the update.
Keep in mind I’ve completed a fan swap. Those stock fans pull about 1.6-1.8A each.
The consumer grade fans only pull .25A. So I’m cutting a bit off the wall there.

Something to think about. From a regulatory standpoint, Bitmain can only really increase power consumption +-10% before running into compliance issues. Especially without warning consumers about an increase outside of the known envelope. The “changelog” for these updates were vague at best.
