Hey guys, 
I am trying to figure out if this is normal for temps, in a heavy stress test I can push my Hybrid to 59C max with memory at 70C  But the only concerning thing to me is GPU2 which I'm not sure where it is , which is reporting 82C.  Where is that located and is that normal?

gpu 2 is backside of chip,just put a fan there.
 
MEM is hotter cuz the inside design is flawed, air cant go through properly

Yeah, I think I'll probably go back to the air cooler, these temps arent any better than the air cooler was in my case. Could it be I need to re-apply thermal paste or is it just the design of the all in one backplate and single fan just being overwhelmed? Should I reapply thermal paste and get new thermal pads? air before the AIO install, mining eth with a pretty big overclock on a 3090 FTW3 Utra

On water right now same oc. Core looks nice and cool but look at that vram and ram. Also the AIO is at full blast for the fans

idle on water seems good but it was good under air too.

Right now I have some really good thermal pads coming; the decision remains, Do I use them to go back to air or stay on water?

I’m probably stressing it more than you since I hit 60c high in core but my men is at 70c at that point.
I heard also that the icx temps other than the core gpu do not matter much to the average consumer but my ocd makes it hard to ignore .

I had a 3090 hybrid that was hitting mid 70s in games. Got a replacement today and I have yet to see it go over 60C. Not sure about the other sensors as I haven't checked them. But it's possible the pump is not good or the thermal paste is not applied properly or heat sink is not making good contact. I recommend you reapply thermal paste and reseat heat sink. If that doesn't help I'd do an RMA on the kit or the card.

What are you getting now at it’s max temp ?


I’m hitting 59 or 60 c doing stress test with port royale. 62c at its worse during occt or furmark.

I don’t think I can get better temps

I just figured there would be a more dramatic change than the big air cooler.

Yo! Chill out! Your temps are exactly where they should be, so no need to get all OCD about it. GPU2 is the backside of the GPU core and 70C is perfectly ok. The part that needs the cooling is getting cooled, so your clocks won't be affected at all and there's no damage occurring to anything. The GPU itself can go to 83C before it will start to thermal throttle, and the backside of your GPU and the PCB can withstand temps much greater than that, so don't worry. I bought the hybrid kit for my 3090 XC3 and just used the pre-applied thermal paste (first time I've ever not just scraped it off and used 3rd party paste) and I'm getting the exact same temps as you. Your air cooler might do a better job cooling GPU2, but your hybrid cooler is 100% for sure doing a better job of cooling your actual GPU, which is much more important. It's not only a vast improvement over the air cooler, it's exactly right in line where liquid cooling should take these cards.

So relax, dude. You're good. 😉👍

Haha!
 
Thanks man. Its what I needed to hear. One thing that this thing is geared for is probably gaming where I use mine for processes that heat up the ram quite a bit. Mining, etc. While I know its not the intended case for it, I like to have it work for me when I'm not playing games. The overclock actually gets a little unstable where it didn't with the air cooler (albeit blasting!).
 
But point taken, that core is def. cooler so the contact is good there.
 

That flir footage is awesome. Its crazy how hot that rear backplate is. I have a fan on top too now. Is that fan sitting on top of the backplate, or is there something in between it?

I have the same question. I'm running eth mining that  stresses  the vram and memory and seeing mid 70's with fans at full blast. GPU 2 is also very hot at 75c. Is this normal? I think that the air cooler performed better than this. Did I make a mistake with this kit? My overclock sits at 1375 for ram, 200 for core. 100 percent power limit

I'm mining some ETH right now on my 3080 XC3 Ultra Hybrid, not knowing the temps my memory is at is giving me a little anxiety.  I check HWInfo though and doesn't say it's thermal throttling so /shrug.  I can go +1300 but pulled it back to +1000.

Yeah, the memory runs pretty hot. But I think the limits are 100C plus for the memory. I feel like the fan cooler did a better job on the memory cooling than the water cooler. The fans on top help a lot.

What is this, your thermal pads or the ram chips?
 
 
 
Also, what are you using for stands offs on the backplate? I'd like to do this too. I'm using screws to offset them a little bit which I think helps airflow.
 
 
 
 
Funny seeing us miners put emphasis on cooling the RAM more than the core. Really the industry is changing and I think its pretty cool. I'd like to see the manufacturers pay more attention to ram and the like cooling as it really is a stability issue.

Is 80C good for memory at a heavy burn test?

I think its just fine. There are reference designs out there throttling when they hit 110c
