which card doesnt?Just for info - I've just wound the fans up to 100% and it's reporting 2600rpm. Sounds like a leaf blower.

You guys are amazing! That guide looks awesome - cheers. @TT158 thanks mate - really appreciate it!
So I locked fans to 30 percent on the FE and all but shut down the case fans and managed to get it to 80 degrees. Totally silent, even when the newly discovered memory junction temperature hit 110 degrees, so the behaviour that you and a few others definitely seems outside of spec.
Let us know how the undervolt goes. Although in my experience, some games (Borderlands 3, for example) can pull 400W even at 900mV (worst case scenario), while others (the new Call of Duty) will be able to use well over 1V while staying under the 400W limit. Basically I'm saying that the impact of setting an undervolt as described here may vary from application to application, so don't be surprised by that.

This video will walk you through it (you can skip to 8:35 for the Nvidia bit):
It's very easy to do and very much recommended for the Founders Editions, since they have pretty strict power limits. You'll get better performance than stock out of the card by dropping to around 950mV, or really drive down temperatures and fan speeds in exchange for a couple of percent performance by going to 850mV or so. An example of the clocks and drop in power draw (numbers might not be identical for you since silicon lottery plays a role):
As you can see, with that particular card they shaved off 57W of power draw whilst only dropping 15MHz from the stock clock, which is great really.
I've tried following those undervolt guides but the wattage stays almost the same as stock until I get to around 875mV-850mV at which point my 3D Mark scores drop by 5-10%
after watching these guides I was under the impression I can save 50-100w without sacrificing performance but it just doesn't work on my card, the card will either crash or by the time I see those wattage savings performance has dropped 5-10%

So I've been doing lots more reading and it sounds like there are a number of other people with the same issue as me. I think it's the temperature of the memory. The gpu itself stays well below 70c. I downloaded HWiNFO64 and it says the memory gets up to 104c and that's when the fans ramp up a crazy amount to 2000rpm. No idea if this is true but, the internet (and my intuition) seems to think that generally triple figures is bad for a components longevity. 3090 has a 3 year warranty so that's some reassurance.
In terms of what I have tried, put an extra fan in at the top of the case and removed a wifi card above the graphics card (just in case it's stopping heat dissipating - doubt it but worth a shot!), have the top air vent on the R6 open and the front panel open too. It has improved things very slightly but not much. I'll try and under-volt next and I have some better case fans coming. This post has some interesting things to say on fan profiles, case fans, thermal pads and undervolting.
Thanks @Ravenger

I will say that my memory junction temp reads around 100 degrees and all is fine. Even when I forced it to hit 110 I didn't get fans ramping up. So still a bit of mystery there.
Better case fans is a good shout. I've got 3x Arctic P14 COs at the front of my case and they're great. The stock fans from fractal are really weak and the low static pressure doesn't work well with the restrictive front door.
Shocking. A £1400 piece of hardware which wasnt properly tested for thermalsAlso this?! https://youtu.be/oVrp6mvwPBk
