3090 version. Yes, mounted on the top. The noise is def coming from the gpu/pump. I will do that now. Leave the radiator connected and shake the card a bit and re-insert. 

Secondary question: are you traditionally mounted, or vertically mounted (showing off the card)?  I've heard a lot of people have noticably worse pump noise when vertically mounting, but I'd assume from the sound of it that's not the case for you.

In order to undervolt, shouldn't you do the opposite and apply a + clock and then cap the top end?
 
You undervolt by using the lowest voltage possible at a certain clock (in other words, you use the highest clock for a certain voltage point). But you cap the top end. So instead of letting the card boost up to 1.05 volts, you cap it to 0.99 volts and use the highest clocks possible at that voltage point.
 
What you are doing is not optimal if you are using a negative core offset. You are reducing the clocks at each voltage point, which is fine, but that is not optimal undervolting. Because by underclocking, you might be running 0.99 volts for 1900 clock when you could be running 1900 clock at 0.98 volts. You get the latter by increasing the core offset.

The pump noise thing is really scaring me away from this card. 

It shouldn't the vast majority don't have problems.
 
3DMark Time Spy Extreme @ completely stock on the GPU: https://www.3dmark.com/3dm/54968818 9108 - that takes down my previous best of 8932 (which was heavily OCed on the 3080) easily, but not by a lot.  Interesting.
 
Even more interesting:
 

 
489W maximum power draw  While I'm happy to see it at least near the advertised 500, I am disappointed it's that close, at STOCK, granted the voltage is way higher than it needs to be for that given frequency, but it seems the headroom even with the higher BIOS stuff, isn't really there.
 
I'll continue this testing after some sleep, been up for 29 hours & I'm officially exhausted.

I would expect a bit more here...OK it's stock, but 489W are a lot of power. I'm evaluating the purchase of an EVGA Hybrid card but I need to understand if it's worth it. Actually I have another branded 3090, a 2x8pin, limited to 390W, and I got 10.769 Graphics score in Time Spy Extreme (total score 10.823). Can you try pushing up your card a bit and see what you get?
 
Thanks :)

What is your setup? You have to keep in mind, Time Spy & Time Spy Extreme scores are effected by CPU differences.  I have a 9900K, if you have a higher core count CPU, that will net you a better score - that's part of why my score isn't that high relatively speaking.
 
I did some custom voltage curve stuff & got 9681 score with a 11206 graphics score.  The highest score on a 9900K with a 3090 on 3DMark's website is 10318, and that's with a 9900K running 5.4GHz.  I'm already Top 40 with a 9900K/single 3090 setup on their HoF.
 
Time Spy Extreme scores don't translate well between systems if you're just comparing GPUs, have to look at the whole picture, it's not like Port Royal where it's 90+% all about the GPU (with CPU & RAM settings having smol effects only).
 
Also, on the 2nd Graphics Test, on the 9681 score, GPU clocks went all over the place, so even that graphics test isn't as high as I can get, if I figure that bit out.

Oh I should mention: I actually swapped the eVGA fans that came with the radiator back in, those things get LOUD at maximum speed, but boy do they push some serious air.  Have them setup on a curve that's based on the exhaust temperature from the GPU's Radiator via thermocouple now.
 
For those asking about temps & the pros/cons of GPU radiator exhausting out of the case vs intaking in to it: Radiator exhaust peaked at 38C - I don't think anyone wants their intake air for their case to be that warm.  That was with a GPU undervolt/OC of 2040MHz @ 994mV, maximum GPU temperature seen was 53C.

Oh wow that is a bit warm. I was going to do as intake because I have my cpu 360mm on top as exhaust. Guess I have to decide which will be intake vs out. I would prefer cooler gpu so I think intake still, and maybe I'll swap when my ek aio 360 shows up.

Now top 40 on the 9900K/Single 3090 leaderboard, LES GO

Was this was undervolting? Is there performance to be gained by undervolting or just heatloss? I am thinking about trying this but really have not tried before.

All background apps closed, same settings as previous result posted, +210/+1100 - I did noticed with Afterburner open that the clocks are pretty all over the place, ranging from 2040 up to 2115 or thereabouts, with those settings...
 

 
https://www.3dmark.com/3dm/55032536 14728 YEEEEEEEEEET That's good for 30th on the 9900K/single 3090 leaderboard!
 
K NOW the party is over time to chill lol

That card is a beast!
Hey quick question, i saw that you run 3440x1440p. Does port royal scale with that resolution? Or does it look stretched or do you have empty gaps on the width? (I believe port royal is 2560x1440p)

djofonunez
So you actually have GPU AIO as exhaust and CPU AIO as intake?
