That’s not what I see, performance definitely goes down once you either reduce voltage or power limit at 4K max settings. The card is definitely pushed beyond’s it’s efficiency sweet spot. I’m fine with losing 5-10% though for the reduced power draw. I don’t use FG or DLSS either.
Lovely setup, I can't work out if the photo is the wrong way round or not
How are the temps now ?
Testing reveals that with the RTX4090, the gaming load power draw can be cut down to 230w whilst losing just 7% performance using an 850mV undervolt
NVIDIA GeForce RTX 4090 power limiting and undervolting test shows only 8% performance drop at half the TDP - VideoCardz.com
NVIDIA RTX 4090 power efficiency tested with power limit/undervolting QuasarZone have an interesting comparison between power limit and undervolting on NVIDIA’s flagship GeForce RTX 4090 GPU. It should be said beforehand that RTX 4090 power efficiency is already quite good which was demonstrated...videocardz.com
Was gonna say, been like 3 weeks now since a 4090 FE restock
This is not always the case, Depends on the software and title your testing this on, I've done loads of undervolts in the past with the 3080 and while locking the voltage does reduce draw in some titles in others that need more juice that use more certain features of a GPU it handicaps them and you lose more performance than you might think.

81C?
I'd be kind of annoyed if I saw that as memory or hotspot temp, but if that is die temp then get that thing out of there asap!

While that is bloody warm for a watercooled card he has stated he likes it nice and quite so fan and pump speed could be set to low which will impact water and core temperature. 80 deg core in furmark at nearly 600w could mean his water temperature is somewhere between 40 and 50 deg ? Warm but not excessive. It won't be hitting 80 in games
@Colonel_Klinck what is your water temp out of interest and what temp do you get if running the card stock in furmark ?If you wanted some sort of comparison i have posted my results in a thread i done in the watercooling section the other day, have rerun Furmark at max power and posted results

Pretty high-water temp but not crazy. That pump is seriously low like you said. I run my D5 at about 2,500 and don't really hear it. Good temps for running fans and pump super low.
same pump speed as me , have it set to 50% and works perfect. in less demanding games i do reduce pump to about 2000rpm ... i doubt the water would circulate in my loop if pump was set to just 1200rpm
I am also getting around 150 l/h at about the same speed as you. Happy I am able to actually get close to 1gpm if I crank the pump speed with my current build, I never used to be able to hit anywhere near that with my previous loop. I blame external reservoir and many angled fittings. This time I tried to keep it as simple as possible.same pump speed as me , have it set to 50% and works perfect. in less demanding games i do reduce pump to about 2000rpm ... i doubt the water would circulate in my loop if pump was set to just 1200rpm
Fitting the ABP has dropped my flow by quite a noticeable amount as was previously up at 180 l/h now 150 l/h , everything fitted correctly so just putting it down to the block being restrictive as temps are all good still... just tried with the pump on 1200rpm and ALARM started flashing on the byski sensor and the little spinning wheel was hardly moving , she definitely needs more pump speed to keep her happy
