Nvidia 30X0 series waterblocks

Sorry, I am sure this has been previously discussed.

It looks like a reference PCB you are using. What card is it exactly?

Also, what Bios and settings on the OC (if using) are you running?

I am on a Palit 3090 Gaming Pro OC at 104% power limit (365W) at +120 on the core and currently 0 change on the memory.

I get a sudden rise up to 45C when under load and then a slow and steady rise (over about 30 mins) up to pretty much always 55c and it stays there.

Nice work on the build again! The things we do for improvements of any kind!

I bet that is still not it's final form ha! :cool:

How much radiator space you got and anything else in the loop?

Am now wondering what temps i will see :p

Hey. I have two 360mm rads.

3090 and 5950X in the same loop.

Also, PCH chipset has an EK block on it which is in the same loop.

Thinking that may be why I get slightly higher temps than perhaps usual.

On the up side I have amazing PCH temps at max 45c.

Fairly happy on the whole.

Just think maybe I cooled too many things in one loop. Although I suppose ppl do have two gpu's in a loop.

Perhaps gpu block isn't quite right but I am trying to resist checking that.
 
Is there any working pci gen 4 risers (actual gen 4 and not just a working gen 3, heard the linkup ones are like that?).

Getting a aorus xtreme waterforce aio and want to mount it vertically... and not lose too much performance.

Or instead, was thinking of getting a case that has a flat motherboard layout so don't need to use a riser .. e.g. thermaltake x5. Not sure if there's any others?

I don’t believe there are any true PCIE 4.0 risers, just Linkup that works with the standard.

I’m planning to run 3090’s vertically too and have already ordered Linkup risers as these were the only ones I could find. I might run some tests with the card fitted direct to the mobo and using the riser to see if the difference is noticeable.

Someone will be able to explain the limitations as to why there are no true gen 4.0 risers available and any potential performance hits of using gen 3.0.

All I will say is, most of the test reviews of 3090 took place on Intel based systems which are PCIE 3.0 so I honestly don’t expect the difference to be significant.

I've had fun recently with 'Gen 4.0' risers. I purchased a LinkUP 20cm PCIE 4.0 riser about a year ago which works fine on my X570 board with a 3080 FE. I've changed my build a little (I'm now using the EK Vertical GPU mount which is fantastic) so I wanted a shorter riser cable, and bought a 15cm LINKUP cable. It didn't work without setting the port to Gen 3.0. I returned it and bought another 4.0 cable of the same model and had the same problem.
So after contacting their support they basically said to return it again. They couldn't explain why a 1 year old cable would work but their newer ones wouldn't, so I'm done with them as far as I'm concerned.
Anyways I figured I may as well try the EK 'PCIE 3.0' riser cable that came with their vertical GPU kit (it's about 15cm in length) and lo and behold it works flawlessly with my 3080 at PCIE 4.0.

I could've saved myself a lot of hassle if I'd just tested it out to start with... :p

Overall buying a riser cable that can support gen 4 is important, because if you have to change the setting back to 3.0 every time you do a bios update it'd be a royal pain in the ass.
 
The debate of gen 4 vs gen 3 riser has been one on my mind for a while now. Last I looked it was like £70 for 4 which is not pleasant

This is good to hear as I was looking to buy that vertical bracket
 
canceled my EK preorder and ordered the bitspower 3090 founders block, couldn't justify the additional cost even if it is a nice block! Just received so will be put in once I sort out the rest of my loop.
 
Can anyone here who has their 3080 or 3090 under water please run the latest version of HWinfo while you are gaming or do a benchmark and report what Memory Junction Temperature you see?

I'm getting 90c on my air cooled 3090, I want to see if those temps go down

86c max 3090 water-cooled with ek block and backplate.
 
A heads up and repost for anyone watercooling their 3080/3090 and has coil whine.

I added an EK water block and backplate for my 3080 and a huge amount of coil whine was present after the swap. I dropped EK an email and was told to remove these thermal pads from the backplate, which solved the issue.

Removing those pads means you won't have direct contact cooling to the VRM. Maybe try to find padding that absorbs vibrations better?

my understanding is this is typically what causes coil whine, vibrations not being completely absorbed by the thermal pad and/or backplate

interestingly enough EK's new active water block backplates promises to completely eliminate coil whine

It's on the backplate only, not the main block. The back plate is optional so not really an issue for cooling, EK are not recommending removing the pads from the main block.
 
I think I've been fortunate. My 3090 hasn't made any noise really, on air or with the Heatkiller block once I installed that, nor has it caused my PSU to whine.
