Just put an order in for mine and getting it this weekend. So you can connect your own fans to the headers coming from the pump? Do those connect to a motherboard header then or just the GPU? First hybrid kit I'm getting so I'm quite new to the install. Noticed there's no mention of swapping fans or fan connectors on the manual online nor do any videos I found address it. Appreciate the help!

You can, it’s just 2x standard 4 pin PWM header.

Thank you for the writeup! What are your temps at?

Where did you get those PCI-E cables that are plugged in to the card?? Just bought my 3080 and this hybrid kit today so super excited. 

They are just Corsair’s braided replacement modular cables with some extra 24 pin combs from the ATX 24 pin I had laying around then bought a couple more. I need to get a 3D printer though and make them myself.

Here is the BIOS updates to turn the card into a HYBRID. Each .zip includes 2 files. One for Normal BIOS and one for OC BIOS. Only install this update if the HYBRID kit is installed.
 
3080 FTW3 HYBRID Kit BIOS =
3080 XC3 HYBRID Kit BIOS =
3090 FTW3 HYBRID Kit BIOS =
3090 XC3 HYBRID Kit BIOS =
 
 
 
 

Any benefit for changing the BIOS?

mine now shows as a hybrid in PX1 and only has 2 fans, which is what a “real“ hybrid would see. Before flashing these, it showed like a normal air FTW3 Ultra (which it was).  I would imagine there are other optimizations beyond how things show up in PX1.  just make sure your switch is in the intended position if/when you flash these. 


Here’s the order I followed and it is working great:
 

1. shut down, make sure switch is in Normal position, boot
2. flash the Normal bios from the zip
3. shut down, flip switch to OC position, boot
4. flash the OC bios from the zip
5. shut down, start up and boot (switch still in OC position)
6. flash the HYBRID XOC bios from the sticky thread

I see! Thanks for the detailed explanation!

It did!  :)
 
Had to uninstall and reinstall EVGA Precision 1.1.4.0 and let that do its up own BIOS update.
 
But now its good to go!!

This went pretty smooth, photos below.
 
Some key points:
 

• The thermal "rubber" on the VRM's is a pain in the ass to clean off.  It flakes.  I used a spudger from an iFixit kit to clean it all out
• The tubes are crisscrossed for front mounting, kinda weird. my 1080 Ti Hybrids weren't like this but it's not a big deal, shouldn't cause any issues.
• Don't freak out once you startup.  The pump will be loud and gurgle for about 3-4 minutes as all the air moves out into the radiator, if doing a top mount that probably won't last as long.  As GN says, don't do a bottom mount.  The pump will be way noisier than the fans if you do that.  After the bubbles move out it's silent, contrary to other posts I saw on here about the 2080 hybrid kits. 
• I didn't replace the TIM on the pump, looks to be solid so far

My results are good, switched from my uV normal profile to the 450w OC profile, saw an improvement of 900 pts with a decent overclock (+125 GPU, +300 mem) in Port Royal, and temps never above 60.  Very pleased but didn't get a lot of time to play with it.   I am using 2 corsair ML fans and am using the commander pro to control them instead of the GPU.  Still going to tweak the profiles a bit and see if I can turn up the pump speed by increasing the "black" connector fan speed.

Were the hybrid kit GPU screws the ones with the spiral metal running around the screw?

Hi, i already have my 3080 ftw3 ultra flashed with the xoc bios of the thread (EVGA GeForce RTX 3080 FTW3 XOC BIOS BETA) now i ordered the hybrid kit and in a few days will came... the questions are: what are the steps to convert the card hybrid and x1 precision recognizes as hybrid? and after that how i flash (or what is) the right xoc hybrid bios? 
Thanks so much for your attention, ill stay tuned for your answer.

congrats on the incoming hybrid kit!  Check out this post, I tried to sum up the steps.

there is no problem if i already have the 3080 ftw3 ultra xoc bios flashed? just follow those steps? and thank u so much for your answer.

I flashed the the normal hybrid, then oc hybrid, then xoc hybrid bios onto mine, but I'm using corsair ML120's on my hybrid rad and controlling them with iCUE.  It shows 0 RPM for FAN1 for me in PX1.  If there is an issue with the hybrid xoc hybrid bios and fans running on high, I haven't noticed it because I'm using iCUE.

THE TUBES are not criss crossed, you just needed to flip the pump 2 turns so that the tubes would be straight, its nice to see how it fits in a 680X, i intend to vertically mount mine with the rad in the front 

My hybrid kit arrives tomorrow. Im super pumped!

Yeah realized that after I got it all together, I don't have spare thermal pads so I won't want to remove it all again.  Oddly the criss-cross helps with the tubes and my bottom intake 140 mm fans, due it it, I can rest one on top of the other and put that cross right over a brace on the fans, so now I don't have them accidentally touching.  The tube vibration, however minimal, was causing them to migrate lower.  When I need to replace the TIM evenually I'll prob fix it then.

Just received the kit, pretty easy to install.  All you need to do is follow the directions.  Overall the kit is great, the fans however.....

I don't use the stock fans and don't use the GPU to control them.  I don't need bling, so I have 2 flat black Corsair ML 120's connected to a commander pro, with a curve adjusted specifically to the GPU temp.  
One thing I don't like, and that's even after flashing the bios, is no pump/fluid temp.  I prefer to base curves on that, rather than the actual GPU temp, but there aren't any spikes so not to concerned.  No ramping up and down like on fan curves set to CPU temps on Ryzen, which is annoying for AIO's.

So the thermal rubber doesn’t come off with standard arctic TIM remover? Thanks.
