@Buttons Update with fixed links.

Also for those who mentioned the extra connector on the PCB, I measured some voltages and my guess is that it was for a planned power button and power LED, one pin was at 5v and another at 3.2v, both common for LEDs. There are a few places on the PCB where provisions have been made for things that aren't there, like bigger LED's.

Both 40x20mm fans with Ultra low noise adapters fitted.

Aren't these fans facing the wrong way? I'm pretty sure they are supposed to be exhaust, not intake.

Normally they would be intake mounted this way, I mounted this way to make running cables easier. Then reversed the polarity to get them to spin the other way.

Not an expert but I think Noctua really studied their blade technology for optimum air flow and low noise, reversing them would defeat the purpose having Noctua fan besides rotation speed and rotation quality.. or am I mistaken?

I did this mod and a few more other things to my Gaming box and its nothing but a sound of some moving air now, no louder than my X360 when its browing the web and running the fan Smile   I am not new to the DIY scene, and used to run a high end computer cooling website back in the 2000's and focused heavily on efficient cooling on things for a decade.   So this was right up my alley.

Using the tips and model numbers in this thread (thanks!) I ordered the same Sunon Mag-Lev model fan for the PSU, but used the Notura ultra quiet fans up front, a 10 and 20mm models,   I used the universal connector "beans" to splice everything together and bought a pack of the JS connectors for it off of Amazon. 

Opening up the PSU vent:




I removed all the fan grates off the PSU area.  I was looking at it, and the fan back there couldn't get almost any air out.  So using some flush cutters I removed all the fan grates in the way, this will let the lower power and quieter fan work more efficiently.  Heck, you could almost go to a Notura 20mm deep fan since it can breathe so much easier now.  

Mounting the Notura fans up front were easy.  To get the 20mm deep fan mounted all I did was use some 3mm machine screws I had that were about 5mm long or less on the hole nearest the mount. 

The 20mm deep versions of fans generally don't move more CFM of air, but have a higher static pressure so they move the same air with more force and can get it through the fan grates easier. 


Running Xcom 2 (game I am kinda into right now) at 3440x1440 on an ultra wide monitor at the highest settings with the 1070 in the case - the GPU temp didn't go much above 72C and was very stable.   It makes some noise when gaming, but... I expect it to.  At Idle and just charging the laptop and doing normal desktop things its pretty quiet.

Figured I would contribute with this, since I have a ton of other questions about the quirks of this whole eGPU deal I am going to need answered coming up Smile

How quiet is this running? I have the RX 580 gaming box and thought I received a bad unit due to how loud it is, I need a nice and quiet environment for productivity. I am sure I can do this fan mod but want to make sure its worth it as I'm considering getting another egpu box but want to try and make this one work as it would be easy to bring to college and back home.

No clue if this thread is still a thing but here is what i used:

For the PSU i got a Sunon EB40201S2-999 which is rated 21dBA at 6200RPM and 7.6 cfm.
As case fans i got myself 2 Sunon MF40101V2-G99-A rated 20.6dBA with 6.96 cfm.

I resoldered all the cables from the original fans and used those for the new ones (since i didn't have those connectors and figured it would be the easiest in order to get the correct cable lengths) - if you plan to do the same, pay attention not to use a too hot soldering iron for the case fans, the insulation is very heat sensitive!
Since the case fans still got quite loud due to the design flaw on the mount (the air is being pressed against the metal frame that holds the fans, since the hole is significantly smaller than the fan) I first thought about getting a heat depending resistor to regulate the fans. Since that would have required me to wait for the resistor to arrive (and get some workaround for the connector) I thought about "why not use one of the temperature controlled fans that are already in the box?" - the graphics cards fan wouldn't work, since it's PWM controlled, and the case fans I got aren't, so I simply took the original cable of the new PSU fan and connected the case fans to the PSU fan connector. Now the fans only spin up when the PSU fan spins up (which works perfectly with GPU load). My Aorus box is super silent in Idle now, without external fans and doesn't get too hot and also does not throttle due to temperature.

@the_livy This is an interesting mod, care to share how it's been holding up these last months? Is see that total amperage for these fans are 0.17A, couldn't find any specification for max current for a single header, but I believe it's way above what these fans are requiring. Idea of this box being silent while doing everyday tasks is very appealing.

How often are these fans spinning up to noticeable levels? I would like to drive 4k display with it, mostly GPU non-intensive tasks.

Sorry for the late answer, haven't checked in here in quite a while.

So far I haven't had any problems at all with my selection of fans. They really only "spin up" when the PSU gets a little load. The PSU fan I got there is (as suggested by the specs) the loudest of them and also the most audible one; I wouldn't say it's annoying, but if you concentrate on it, it can become recognizable! I'm usually playing games on the card and usually run it limited to about 85% Power Limit set with MSI Afterburner (and set to run on boot); i also changed the GPU fan curve in order to have the fan spin up at 35° with 14% (in order to reduce heat that's accumulated within the eGPU case; keeping the GPU fan at the lowest rate helps doing so without adding up to volume). Amongst what I played, I never had any issues with temperature on neither the GPU nor seemed to ever have reduced power output by the PSU, so i would consider the mod to be successful; however, like I said, I usually don't run the card at 100% since a reduction of about 15% in power limits only leads to a reduced performance of about 3-4% which is clearly worth the trade for reduced component wear and reduced overall volume.
To answer the other two questions: the fans almost only spin up when there is medium to high load on the GPU. Sometimes they will come up higher when my laptop draws more power over a longer period of time. Apart from that, I don't have the numbers in my head right now, but yes, the Sunon case fans do have lower current requirements than the standard ones, but that doesn't really matter, the only thing that matters is the voltage; the currency is basically just there for telling how much draw can be expected in order to choose the correct cables; since the fans I chose had lower currency ratings than the original ones, I therefore didn't have to care about changing anything here and also automatically knew that they will be able to run at least as good as the original ones; however, like in my first post, I noticed the too high and quite solid voltage on the case fan connectors; which is why I went with the 2-Pin connector of the PSU in order to get temperature controlled case fans (since GPU load automatically means higher PSU load and therefore an increase in PSU temperature, it was easy to just go with this); the only thing that worried me at first was the fact that the fans couldn't get back to 100% anymore as they could before (sometimes the stock fans would go even louder than in idle) - but, almost 4 months later: no problems at all; GPU temps max out at around 75°C with my fan curve and the PSU doesn't seem to be dying either (I guess that's why they chose to go with a 450W instead of a sufficient 350W PSU after all) - so, I can definitely recommend the fans I picked to anyone seeking for a less noisy box out there!

EDIT: I forgot to mention that I usually have my eGPU under my desk, using a 2m active TB3 cable in order to achieve that (laptop is on the desk in a vertical stand and closed lid, luckily boots up when it gets external power; so my power switch on the socket functions as my PC boot trigger)

ADD: Just put the eGPU next to my TV (about 3m away from my couch), it's about the same volume as the 2.5" HDD that's mounted to the back of my TV (a little less annoying though and possibly not even as loud, can't tell with 100% accuracy what is what of all that i hear)

Not a full expert either, but picking up some knowledge and thoughts about aerodynamics, especially airflow of propellers and such, I would clearly not recommend running with reverted polarity; instead, really try to squeeze the cables in with force and have them run correctly - this will help in both noise and airflow (in two ways, first off flow precision (turbulence and such) and second (as a result of the first) the amount of air the fans can actually transport). Besides, while I also thought about changing the PSU fan from pulling out at the back and pushing in from the side instead, I ended up with the conclusion of this not being the best idea either, due to how the rest of the case is designed. In case of the original mount, the fan will pull out hot air, while cool air will find it's own way into the PSU; changing to a push cool air might lead to an overflow and creation of just a warm pillow of air inside the PSU that might not find it's way out; the airflow isn't really frictionless in this PSU, it's really tight and there is a lot of resistance; so, please, do not change the system from pull to push entirely! maybe go for a silent pull fan and add a main push fan, but reconsider the risk of a dead PSU from heat before removing the pulling fan from the PSU!

@the_livy this is a bit off topic from the fan modifications. However, do you think a re-paste of the GPU with better quality TIM or thermal pads would also help the fan noise? My thought is that it would reduce GPU temps due to more efficient heat transfer and the lower temps would result in slower fans needed to drive out the heat.

My thought is that it would reduce GPU temps due to more efficient heat transfer and the lower temps would result in slower fans needed to drive out the heat.

I think that might be a little overkill, the only thing that would change by re-pasting would be how much heat is delivered to the graphics cards cooler; which doesn't mean the fans would have to do more or less at all, it just means that more heat will be carried away by the graphics cards cooler (if even noticeable); the result would be slightly less heat on the back of the card; which means that only the case fans have less to push out and also that slightly less heat is translated from the gpu to the PSU (while, depending on the efficiency of the PSU, it's not said that the PSU doesn't push out more heat over to the graphics card instead)
In other words, the only gain you get from a re-paste might be that you would need to have your graphics cards cooler to run higher since passive cooling is most likely much out of question anyway in this tight form factor with all the other heating components so close by.

ADD: I just got another idea i might give a try soon: unless you really need the performance, setting up a stable overclock offset with MSI Afterburner and a PStateLimit with NvidiaInspector might be the solution to get it down to about a GTX 1050Ti with even less heat generation while still keeping the option to go higher if necessary (i often encounter higher GPU clocks in some games for no real reason; which would run just as well on the lower clock (limiting to the lower state would limit the clock to the desired state and keep the GPU cooler in low to medium load states, where it would otherwise just clock up to maximum power and heat up more; however, I sometimes, in the past, have seen an opposing effect of limiting the pstate, where the GPU ended up getting hotter with lower clocks due to higher overall load (still couldn't come up with an answer to what exactly is going on in that scenario))) - turns out the overclock is only applied to P0 and not to any other Pstate; so that idea doesn't work as hoped; might still be a solution for games that trigger the higher pstate without requiring the extra power.

idle

Here is a screenshot of my modified fan curve and clock/power settings within MSI Afterburner; like this, the performance is basically the same as of a GTX 1060 6GB but at reduced power draw (about 30% less, i think) which is sufficient for my demands and also keeps the whole thing really quiet!
