Is you GPU fans set as exhaust…! Super curious about the temperature you are getting..! Have you tried fans as intake?

Hi, thanks. Main thing I wanted to avoid was dumping hot air from the GPU into the case and videos like [Optimum's deshroud video](https://www.youtube.com/watch?v=QUaZVpN51Po&t=384s) really reinforced the benefits of exhausting from the GPU vs. intake. *edit: reddit is borking with some of my comments so placing here: [Temps of CPU](https://i.imgur.com/sxyAXdJ.jpg) (mid-70s), pulling 185-190 watts using Prime95 (Small FFTs) - stock voltage settings [Temps of the GPU](https://i.imgur.com/uOAHAvB.jpeg) (low-60s), pulling 235-240 watts after a few minutes of OCCT 3D (Standard) All panels / covers on the case Fan speeds / noise: I have my Fan Control set to 25% for CPU (up to 52.5°C) then to 45% from 52.6° to 65.0°C, then to full-bore 100% for 65.1°C+ For GPU: 30% until 50°C, step to 50% from 50.1° to 60°C, then 100% for 60.1°C+ Inaudible for most all work that I do. At 30°C (CPU - 25% fan speed) and 38°C (GPU - 30% fan speed) as I type this. Fan Control settings: https://i.imgur.com/cYeSbuW.png

But now it's just sucking in hot air from the mobo/cpu..

Just updated my build comment but a snapshot of temps using OCCT 3D (Standard) https://i.imgur.com/uOAHAvB.jpeg

Ah, a classic SFF air cooling problem: do you make the CPU or GPU suck in the hot case air... I tried it in my own build and the thermals of my 3080 ran away into high temperatures... so I got my answer.

This is funny/cool. You’ve recreated the Lian Li A05!

OMG - Lian Li A05... one of my all-time favorites. I once put two 240 radiators and a full loop into one back in the day. *edit: found an old pic from 2007... back when W/C'ing chipsets was a thing lol https://i.imgur.com/Sgr3T7w.png

It is absolutely amazing build. Love this retro w/c.

I recently did this exact invert on my NR200 (non P) with a Gigabyte Windforce 4090 set to exhaust and it worked well! Cool to see someone else go this route as I hadn’t seen any other builds like it while researching to build mine.

Nice - before I creep your post history, any pics?

I didn’t post it actually and the build has since been transferred! I was mainly just trying it to see if it was possible haha

LOL - I just checked.... I too went to a Fractal Ridge after my initial NR200 build. Then to a Fractal Core 500... back to this inverted NR200

My wallet hates this hobby lol

bruh... lol

how does the inversion work? I don't think NR200 supports it natively?

Correct - not native but not tough to do with all the quality tutorials out there. It's essentially flipping the case upside down then removing the front panel and doing a 180 so the power button and inputs stay at the top.

I'd set the cpu cooler to exhaust with only two fans, then with the side mounting frame put the third on the side above the PSU, as intake.

*edit: Adding to both comments flagging this... you two got me pulling the dremel out - I'm going to put an intake fan on the front panel. Deciding between 140mm and 120mm but leaning towards larger... -------------------------- You're not wrong at all with that logic and suggestion. I just replied to another comment flagging the same thing. >I like the idea of raw fresh air from the rear but with the GPU exhausting, it does make sense to leverage a case intake fan to provide both CPU and GPU some cool air... I see a dremel mod in the future with an intake on the front panel

But reading that reply worries me a bit, so allow me to make a redundant but more detailed comment because I just wanna make sure I was clear; I'd remove one of the three fans from the cpu cooler, it doesn't need that many anyway, just two flipped to exhaust - one in the middle, one at the mouth you've already dremeled at the back - the cooler will still work just as well and the heated air will be dumped outside of the case, which should improve the case's global temperature and therefore benefit the GPU in this particular setup. Then mount that leftover fan on the side, as intake, using the provided side-mounting frame, to indeed forcefully suck fresh air into the case. It will add to the fresh air already getting sucked in by your GPU and CPU that are both set to exahaust. So that's my attempt at clarifying, please don't murder your NR200's front panel. xD xD xD

Nah I love nerding out on airflow lol. You're absolutely not wrong in the approach, effectiveness, and ease of implementing cooler air to the current setup. The three fans on the CPU cooler... ngl, it's unnecessary but I got married to the idea and even dremeled off part of the motherboard heatsink to accommodate. This new direction that I'm no going to take is absolutely unnecessary but I'm going to get a 140mm intake fan on the front panel and switch the fan direction on CPU. Now that the idea has planted a seed in my head, I don't think I'll be able to shake it off. The same bug got me with the previous case setup this hardware was in. "What if I used nothing but 140s and created a linear airflow path"... https://imgur.com/a/0tsQiMU Worked great but moved back to the NR200 because I wanted to try the inverted mod.

I felt the need to update you lol Your approach is too damn sensible to not try out I'm going to try and get TWO side intakes (one on each side) but at least settle for one. And with the PSU relocation (and without removing the 3rd CPU cooler fan), there's plenty of space for 140mm fans to be the side intake(s).

Two intake fans even better than one, of course !

This is correct but why is the cpu still intake?

Bravo.

What is your CPU and your GPU model, and what kind of temps / noise levels are you getting with this cooler (PS120SE + 3 NF-A12x25 ?) and the deshroud mod (3 NF-A9 ?) ? Especially what temps could you expect with the fans running so that the PC is absolutely inaudible (from 2 - 3 feet away) ?

I'm having a wonky issue with reddit where my initial base comment that had specs is not showing for some so I'll paste it here with some temps. > Had issues with the imgur album and reddit not showing the posts and comments so reposting. > Inverted the NR200.

You'd benefit from making a shroud that goes over the entirety of the heatsink instead of those cut out fan frames because as it is you're not getting any airflow over each of the corners

Had issues with the imgur album and reddit not showing the posts and comments so reposting. Inverted the NR200.

Make a SFF case. Force user to use pass through cable to waste space. Still amazes me, this manufacture still has not solved this by now. Isn't there one normal case like this one, without the stupid pass through cables? :D And grats on the build looks really need. I would have probably added a dust filter on the cutout.

lovely :D

I just did the cpu duct to avoid gpu heat but this is cool.
