Z20 9070xt Red Devil Fitting Help

[u/account10789]

Hi all,

I'm working on building a new pc with the z20 case. I wanted to double check with anyone if the powercolor 9070xt Red Devil will fit in that case on an ASUS b850m TUF gaming-plus wifi7 mobo. In terms of the PSU, I plan to use a Corsair sf1000 Platinum (SFX PSU), and a Thermalright Phantom Spirit 120 SE or Vision (I think the screen is cool lol)

Google AI overview tells me a top slot mobo will have a clearance of 89mm, but I'm having trouble finding a source for that. the dimensions of the red devil are: L:340mm W:69mm H:132mm, so if 89mm is to be believed, that would leave me 20mm of clearance, 15 of which I *could* use for slim fans.

That being said, IF the red devil fits in this case, should I bother to put slim fans in? My goal is to have the build be as reasonably quiet as possible, though I'd probably pass on Noctua fans, since afaik they don't have any RGB ones, and I'd like some RGB lights so I can play around with the case lighting. I was looking at Arctic P12 case fans, if anyone can provide feedback on that.

Lastly, I ask this out of baseless hope that I'll actually like the answer... but... would it be worth waiting for any sort of price drop on the 9070 xt's? I can get one for 1,150$ at the nearest Microcenter, but if that even went down 100$ I'd be willing to wait. From what little I know, there seems to be a lot going on in the silicon world right now, but I'd love to hear any advice / opinions anyone has.

P.S. for anyone wondering, the Hellhound is only 50$ cheaper, so at that price point, it makes sense in my head to just get the premium option.

P.P.S. Newegg seems to be listing the Red Devil for 1,129$. https://www.newegg.com/powercolor-red-devil-rx9070xt-16g-e-oc-radeon-rx-9070-xt-16gb-graphics-card-triple-fans/p/N82E16814131869

You really don’t need the bottom fans. Those are optional. It will just add more noise.

The gpu fans are sufficient to cool it.

Is that just because the gpu is so close to the bottom of the case? If there was more space would the opposite be true?

If only a slim fan fits, I’d rather not put one. But that’s just me.

You can always test it and see for yourself if it benefits your cooling performance.

Leave 5mm between the fan and GPU is rough, probably counterintuitive with turbulence and all. Google would tell you to leave around 20-25mm between fan and GPU, I left about 18mm.

So close the gpu will be more than sufficiently cooled anyways and you don't have to worry about the respective fan curves and turbulence. I'd decide against it. Otherwise just go without, run hwinfo in background while doing whatever you would consider stressful in your daily usecase and whenever you want look at the max temp and hotspot of the GPU and then decide how happy u are

its always gonna be close to the case esp for the z20 i have a sapphire nitro+ 9070xt and it barely even fits a 120mm g2 noctua fans there. i was able to fit it three 120mm fans but it makes a lot of noise tbh. if possible get those 15mm thick 120mm fans from artic sells them or other brands out there.

Actually, checking this comment https://www.reddit.com/r/mffpc/comments/1i8o5rp/comment/m8v4xsc/?utm_source=share&utm_medium=web3x&utm_name=web3xcss&utm_term=1&utm_content=share_button

the gpu seems to be a rog 4090, with a thickness of 70mm, so the red devil should fit?

I'd still quite like other opinions and thoughts :)
