First time custom water cooling, help needed ( 3090FE )

[MikeTimbers]

Thanks for the feedback, I think its most sensible to go with a full loop as mentioned.

The 3090 is *really* long, but the PCB is considerably smaller.

I wonder if its worth going with one of the radiators with low profile radiator and fans?

low profile radiators give low profile cooling. you want as good as you have but with less noise and low profile rads won't give you that.

I also wonder if something like the 'SWIFTECH APOGEE DRIVE II' which is a CPU block and pump integrated can save some space?

There is a really nice block/pump here with something like this you could then realistically go top rad and front rad. A 240+280 would be enough to cool but whether it could get both good temps and be quiet is another matter.

Perfect for small form factor builds although filling might be a bore. Somehow if silence is the driving factor you need to overwhelm the heat generators with radiators because powerful fans=loud fans.

This was with alphacools xpx aurora block for the 3090, im waiting on delivery of the watercool heatkiller V block so will see how that performs in comparison, not expecting miracles but we'll see.

I'm using the Aurora GPX-N, as above it performs well enough for me. My housemate has the Heatkiller V on his since yesterday, it does appear to perform even better (though he has more cooling in the loop overall, so it's not apples to apples).

Will also try with LM compared to traditional paste

Same housemate managed to tear apart a delidded 9900K as the liquid metal had somehow fused the silicon to the nickel plating of the block, and even with a guard etc it possibly cracked under mounting pressure. Nothing was left of the CPU after removing the block (half the CPU die came with it), which was an expensive exercise in trying to chase down some numbers that don't effectively matter. I'm not going anywhere near Liquid Metal!

Whats his cooling solution like in his rig? Im running mine of a single thick 360 radiator.

Hmmm thats not good! Not had this issue myself personally but its been quite a few years since i've touched LM.

You could deshroud and and strap a couple of 120mm noctua fans on although this won't look as classy as a custom water setup it should solve the noise issue without needing to spend much.

Deshrouding a 3090FE isn't really possible, but this gave me the idea of just strapping the Noctua fans I have to my GPU and making sure the air flowed in the same direction. Thanks for the suggestion!

I made a bit of a hacky mod and attached the fans to the motherboard header and linked it to GPU temperature and maxed them out at around 1200RPM, then turned the FE fans down to 30%.

Temps have dropped drastically and the card is now sitting at around 60C under heavy load and the system is basically silent, not terrible for a couple of fans I had lying around anyway... Gives me chance to consider the watercooling properly and potentially a different case.

proper ghetto mod!

Jeez. That is something.
