Should I try and fit an RTX 3090 in a FD Node 804 Case or stick with RTX 3080?

So, I am not sure if this thread is better served here or under cases.

As the title states, I am still flip flopping back and forth if I should go for the RTX 3080, which will offer no challenges what-so-ever in getting it to fit my Fractal Design Node 804 case, or if I can go with the RTX 3090 in the same case but with a few potential challenges.

Background:
I am building a new PC. In a nutshell, the main hardware is:
  • Fractal Design Node 804 mATX case
  • Ryzen 9 3900 XT (a placeholder until Zen 3 comes out)
  • Asus ROG Crosshair VIII Impact X570 mDTX motherboard
  • 32GB G.Skill Trident Neo DDR4 3600 CL16 RAM
  • Corsair AX1000 PSU
  • Custom water loop
    • 2x Corsair XR7 240mm x 54mm radiators
    • 4x BeQuiet SilentWings 3 120mm HS fans
    • EK-Quantum Kinetic TBE D5 reservoir/pump combo
    • Optimus Foundation CPU Block for AMD
Aside from the graphics card, I have everything on hand except for the CPU water block. COVID hit Optimus' assembly and shipping, causing delays.

For those unaware, this is a cuboid style case broken into two chambers, the motherboard side and the power supply side. The radiators are going in the top of the case, one in each chamber, and the pump/reservoir will be in the power supply chamber. Initially, I was going to have 4 120mm intake fans on the front of the case, two in each chamber, but this has changed as I was able to start piecing it together. Cable management might force me to remove one intake fan from the power supply chamber and the way Fractal Design offsets the radiators in the top prevents me from putting two 120mm intake fans in the motherboard chamber, leaving me with just one. Both chambers will have rear 120mm exhaust fans. There is quite a bit of filter ventilation on the bottom of the case too for air to be pulled in through, but no fans at the moment.

The case can accept graphics cards up to 290mm in length while retaining a 25mm thick intake fan. If you are able to make do without the intake fan, you can fit a graphics card up to 320mm in length. So this is where the dilemma comes into play. If I stick with the RTX 3080, there are absolutely no issues with installation since the FE model is listed as being 285mm in length. This should let me keep the one intake case fan in the motherboard chamber in place, blowing cool air directly onto the graphics card. If I decide to go the RTX 3090 route, I will have to remove that one intake case fan since the FE graphics card is listed as being 313mm in length.

With having two 120mm fans on the radiator in the top of that chamber pushing air through the radiator and out the case and having a single 120mm exhaust case fan in the rear, will I have sufficient airflow for the RTX 3090? My initial thought is that the fans on the graphics card look to be pretty large and may help contribute to some of the pulling of air into the case from both the front as well as the vents at the bottom of the case. But is it enough to actually draw fresh air in? If I go the RTX 3090 route, should I try and fit some fans at the bottom of the case to pull air through the vents and have it blow over the graphics card? From the looks of it, I can fit some 120mm fans on the bottom but there is no native way to mount them. Looking at a Legit Reviews article on the case, it appears that the bottom does have mounting points for two 80mm fans (which the Noctua NF-A8 PWM Chromax may be a good choice), which would keep me from having to modify the case.

Throwing cost aside and focusing just on whether it is an option that will work while not creating a negative impact on airflow/sound/heat/performance, is it something that is doable or even recommended?

Is not having that one 120mm case fan in the front going to make enough of a difference in fresh airflow working its way into the case? Will adding two 80mm fans at the bottom to pull in air from there instead be a good alternative to the single front 120mm case fan?

The Noctua's specs for the 80mm fans list them as being pretty quiet, but a small fan at higher RPM will always have a higher likelihood of being louder than a larger fan running at a lower RPM. For comparison, the front case fan is a BeQuiet Silent Wings 3 120mm HS.

While I am not expecting a completely silent PC, I would like a quiet one. My current build (see signature) is pretty quiet with day to day activities but does start to get loud when playing GPU intensive games. My hope is the new build will be quieter or at least have a sound perception that doesn't get annoying.

seems like a pain, not worth it unless you think a 3080 will leave you disappointed...

I would also like to add that I want to eventually tie the GPU into the custom water loop as well. But with the FE board being pretty new and water blocks just now being announced, that may have to wait until next year when there are some how-to videos posted.

I game on a 4K monitor and VR with a Valve Index. Ideally, I like to run things at max settings at full resolution (who doesn't?). Also, I usually only replace my video cards about once every 4 years. I just want to feel comfortable that I can get that kind of experience for 3-4 years without swapping cards and the 10GB on the 3080 is still leaving a slight concern in the back of my head.

I guess the other option is to stick with the RTX 3080, pocket the difference between it and the RTX 3090, don't put a water block on it, and upgrade sooner when a refresh model comes out with more memory. Then sell the RTX 3080 to offset any remaining costs.

Either video card is faster than the GTX 1080 that I am currently using.

yeah , go 3080. you can probably handle stock cooler, and pocket the difference for whatever comes after ampere.

Your case can handle 6x120mm fans, so there's no way you can't handle 450w air cooling...but that gimmicky cooling regions shit should have stayed in full-size ATX.

The 3080 is faster than a 2080ti if what we know is true. Even after the 3090 comes out, the 3080 will essentially be the second fastest gpu available. It's up to you but if you lose that front fan I don't think the 3090 will be happy.

Yeah, I keep going back and forth. The 3080 will be the better choice. But if I can't score a 3080 FE on release day, then I may want to try and see if I can snag a 3090 FE the following week.

Actually, the case can handle 10x120mm fans if you count both chambers, 5 on each side, or 12 if you count two 80mm fans in the bottom of the motherboard chamber. If it wasn't for the radiators, I could even go with 4x140mm fans in the top and the PSU chamber can take a 140mm fan for the exhaust (but I figured that is overkill for that side). Because of the way the motherboard chamber's radiator is offset, I can only fit 9x120mm fans in the case.

Right now, I have 5 fans in the power supply chamber (2 intake, 1 rear exhaust, 2 on radiator exhausting up and out) but that will probably be knocked down to 4 to give more room for cable management by removing one of the intake fans. The motherboard chamber has 4 fans right now (1 intake, 1 rear exhaust, 2 on radiator exhausting up and out). Going with a RTX 3080 will allow me to keep them all in place. Going with the RTX 3090 will force me to remove the front intake and be down to 3 fans or I will need to add two 80mm fans on the bottom, pulling in air from the bottom filtered vents.

Yep!

Trust me, I have measured, double measured, triple measured, and more. Working in a fairly tight space, I have been needing to measure to fine tolerances for most of my other parts.

This is also why I am determined to get an Nvidia Founders Edition video card since their sizes are pretty well documented by Nvidia already and will fit in my case. The AIBs are just now starting to leak out their sizes and even for the 3080 they are huge, putting them close to the size of a 3090 Founders Edition and, in some cases, even larger.

I have a Define C if the 3090 is 1MM longer than they say it won't fit, still debating on getting the 3080 over the 3090. Probably will get the 3090 because I really want to play Cyberpunk 2077 at the highest possible settings I can at 4K.
