TLDR:  Temps are a little higher than I expected, and fans get up to 80% just playing D2R (card boosts 1875-1950 range), how do I check that the pump is working correctly (correct flow rate)?  There was no manual with the card and can’t find anything online, just want to ensure before I tune that I haven’t somehow missed something.  What software actually shows me how the pump is performing?
 
Long version:
Hey, sorry I tried to find my own info but came up empty.  I have been lucky enough to secure a 3080ti FTW Ultra Hybrid after waiting since the 3080 non ti launch (My 3080 Hybrid order was bumped up to Ti) – so 10month wait since I ordered the 3080 Hybrid lol!
 
I have installed the card and everything works, however my temps maybe a little higher than I expected – 73C playing D2R @ 144Hz.  I haven’t tried mucking about with power limits or undervolting just yet (I had Zotac Amp Holo 3080 as my filler card and had that all set up with undervolt etc so familiar on that aspect).
 
I really wanted the Hybrid predominantly to ensure all heat dumped is outside of the case as my Zotac 3080 really made the entire case an oven even though I had 3 intake and 3 exhaust fans.  At this point its worked like I had hoped but obviously the temps at stock settings are on the higher side of what I hoped so I am trying to ensure that pump is in fact working at correct speeds.
 
One disappointing aspect of this purchase is the non existent manual for the hybrid product, I mean there was nothing in my box other than a regular 3080ti foldout that just showed the 3 PCIE power connection process.  I had hoped that there may be some more info on monitoring etc of the card (still looking online)
 
Anyway if anyone has any advice or personal experience I’d appreciate the feedback, I’ll dial in the tuning once I know everything is ok.
I will consider applying some new thermal compound/pads but seeing as the card is less than a week old I’ll leave that as last resort!

People reporting temps @65C, I'm @73C and fans spin up to 80% playing D2R, decent airflow case, though ambient probably a little higher (no AC in this room).  Just want to ensure that there is no setting for the pump flow speed, usually AIO style coolers have fan and pump speed just working out where to find it if avail.

See thats my issue, I want to make sure the pump is working..  My temps are ****; this test is performed with side off.. look at my junction temps - i tried to emulate your settings.  Not sure whats going on here, but either the thermal pads are not making good contact or something going on with pump.  I had better temps with my air cooled zotac on the junction.  And clock is low as you can see, your temps are so much better.  I am well aware that all cards are different but this is very different!
 

 

Are you pushing OC or a higher Power target?

If you can't provide detailed info nobody can help you.  Until proven otherwise, the card is fine, you just have it set up poorly.

Idk if it’s his setup. Also on a 3080 Ti hybrid and I’m seeing similar temps in a o11 dynamic mini with 3x120mm bottom intake and 2x140mm side intake running 100%. Top exhaust with the hybrid rad. My 3080 on air struggled to break 65C on 50% fans, but this hybrid will hit 76C core, 87C hotspot with 100C memory junction temps in Control. I’m going to RMA, my case airflow is good, have heard more people specifically on the Ti complain about this.

Thanks for providing some detailed info.  What is your average card power at those temps, what are your card fan speeds, how fast are your other intake fans, what is your CPU cooler config and power level, and what are your ambient temps?

Everything is stock. No OC and the power limit untouched at 395 watts average. Card fan speeds are 2100rpm for the rad and 2400 rpm on the VRM fan. Ambient temps are 20-21C cpu cooler is a Corsair h115i elite capellix 280mm aio set to side intake with push pull ML 140’s, bottom 120mm fans are LL120’s. ML’s are at 1800 rpm, LL’s at 2000 rpm.

Cpu is a ryzen 5800x at default power level, averaging 60C during gaming. When I open the side panel during gaming I drop 1-2C on the core and hotspot however memory junction stays at 100C. Card was bought as a hybrid straight from EVGA. All case and radiator fans at 100% with these temps. If it had a fan I maxed it out and these temps are terrible.

I have not swapped out rad fans or tried push-pull on it yet. I was going to add 2 noctua nf-f12 on the pull side of the radiator but as soon as I saw these temps stock I thought RMA. No hybrid should run this hot from the factory with good airflow. A disproportionate number of 3080 Ti owners are reporting similar results.

Edit: didn’t mean to hijack your thread op, just adding I’m seeing similar results.

Yeah that's pretty wrong, worse than a 3080 Ti FTW3 Ultra.  RMA time.  Though personally I'd do a re-mount myself first.

Then something is wrong.
My 3080ti Hybrid (in a O11 Dynamic, with be quiet Silentwings fans on the rad) reaches around 55° under FULL Load in 3D mark with coolers @ 100%, and 60° @1860 MHz with fans at ~50% in MSFS (daily profile).
Memory junction I am at around 70° (added thermal pads on the backside).
 
So you guys have either an airflow problem, but like kevin said: If the pump is not running you would notice it right away.

It’s not an airflow problem. I just heard from EVGA and they agree something is wrong with the card. Pending RMA, ugh.
