@@shacacoora How did you connect them? I have a nitro+ which has 1 4-pin and 1 8-pin connector, both going to its 3 fans. I've not found any adapters for that yet nor do I know the name of the connectors.
Hey James! I just connected them all together with a couple of Y-split fan cables and plugged them into a fan header on the motherboard. I then used the "Fan Control" software to link my GPU temp. with a custom fan speed graph. @@jamesm5192
TIPS: 1) I had COIL WHINE noise when I used Noctua fans to mod my GTX1080. Probably due to the extra current draw. I ended up putting the 2nd Noctua fan cable to the MOTHERBOARD case fan header. I then used "Fan Control" software to adjust RPM based on the GPU temperature. Worked great! 2) My new Asus RTX4070 Dual OC card is slightly disappointing. The fans turn ON at 55degC and off at 40degC. That's fine, but the fans turn on at 1000RPM which I can hear if the sound is off or quiet from the speakers. If the fans started at QUIETER it would make far more sense. (you can NOT drop the fan speed lower. And trying to set ANY custom fan profile disables the fan's ability to turn off. So if I try to make fans quieter at HIGHER temperatures then the fans spin at a MINIMUM of 1000RPM. Sigh. Why?) 3) MODDING is something I'm considering but any modded fans would still start at 1000RPM (AFAIK) and the Low Noise Adapter wouldn't help. The voltage with an LNA is lower, but the fan sends the tach data back to the graphics card so it KNOWS what the fan RPM is and would likely just adjust the Duty Cycle for the 12V to match that... so the MAIN advantage for my card would be to get the fans that are QUIETEST at 1000RPM. 4) The Noctua NF-A9 PWM (chromax black) appears to be the optimal fan for me. You don't want the fan to extend BEYOND the heatsink. I looked at the SLIM version of this fan but the power usage is much higher so I wouldn't want to hook it up to my card. 5) There's a 4-pin PWM adapter needed usually as the graphics card 4-pin is smaller than CASE FAN connecors ** 6) My GTX1080 fans were set to start at roughly 400RPM. I couldn't hear the fans spin usually even when gaming with no sound on! I did a sharp ramp up from 78degC to 83degC so usually my Noctua fans were spinning at no more than 600RPM (sitting in the 70's).
So I did a similar mod but with 3 NF-A9's on my Sapphire RX 7900 XTX Nitro+ and am able to run them quite low RPM while maintaining temps and much reduced acoustics.
Even if the same temps are supposedly achieved with the same revolutions, the Noctua fans are much quieter and sound more pleasant. I'm really thinking about doing a mod like this because my original fans are whirring. I don't know anyone who runs their GPU at 3k! That sounds like a jet and you don't want to play next to it!
I had a Palit GT 740 with one fan smaller than 90mm, and when I replaced it with two 120mm fans, I got a better temperature with a maximum of 56C in gaming. Yes, it is better to use an aftermarket fan when you have a tiny fan or only one fan in the GPU. :)
The Noctua 120mm fans will need less RPM to achieve the same temperature. And even when they spin with the same RPM as the original fans, they will be way more quiet. U cant tell me that u let ur graphics card run on max fan rpm all the time. The only time u need that, would be for high overclocking benchmarks. And even then, u can get noctua nf f12 fans that spin up to 3000 rpm, which are optimized for static pressure. And as an addition to that, if u connect those 3 fans directly to the mainboard, u dont draw any additional power from ur graphics card. Which in this case gives u a maximum headroom of 10 watts when all 3 fans spin at max rpm. which then helps with overclocking records. And the wider area of airflow will also help to cool down other parts like the vrams and other things on ur card. Check it with HWinfo. The core temp is not the only thing that needs to be measured.
The thing about deshroud and replacing fans with case fans is that you can actually have high quality fans instead of whatever comes with the gpu. you can use tapes to cover off fan areas that doesn't blow air into the heatsink. This will result in a boost of static pressure towards non-covered area.
I don't have the card currently but maybe thinking about buying it someday... In case the original fans would fail, this is a good solution I think. Is it a 3 into 1 splitter cable that goes into the original connector on the board? Thanks for testing this
I spoke with XFX recently regarding these Merc 310 cards and requested information on the thermal pad sizes used on them. They reported that 0.5mm and 1.0mm thickness were what was used. Can you confirm, or deny this information if you got that far into the card? It's honestly very believable that this card performed worse on Noctua's fans - IDK who manufactured the fans that XFX used on these cards; but I'm having a difficult time convincing myself that they're not delta's because their performance is absolutely INSANE for the size.
Unfortunately I returned it. I purchased the card solely to 3D print 120MM brackets and to test it out. And I agree, the fans that come with this model KICK ASS and more than likely will be able to suit the needs of a lot of people.
@@shacacoora I love it. Thanks, a ton! That'll save me a lot of time with the calipers and cad software to draft up an implementation of my own to test some other configurations in the future.
That's not how quiet Noctuas are at max. rpm though. I can clearly hear mine at 1600rpm sitting at my desk (PC is under the desk on the floor) while I have a standing fan running in my room.
If I were to redo this test I would use fans that could match the RPM on the XFX stock fans. As it would be more of a fair comparison. Based on the price I'm seeing for the ARCTIC PWM Max, I'll definitely be giving them a shot next time around.
7900xtx merc310 and it has this sound that I can only describe as a "metallic rattle" at high speeds. At low speeds, it sounds like one fan needs a serpentine belt change....I think it might be the design...the fins might be shaking at high fan speeds or something. I can't see or pinpoint exactly where the sound is. I put 3 Arctic p12 max 120's on it and have the exact same sound(they do drop temps by a few C during testing). It's like a heat shield on an exhaust type noise, and it's so annoying if I'm not using headphones. I think I'm going to just buy a water block for it. I put 3 Arctic p12 max 120's on it and have the exact same high speed rattle.
Larger fans tend to move more air at less rpms compared to smaller fans... not sure how this mod wouldn't be able increase cooling with less noise... Your benchmark also seems to lean in favor of the mod as you had better frame rate and temps with the modded fans... not sure why you would not recommend the mod exactly. From my experience modding with custom fans in the past, Using both methods of connecting them to the gpus header, and also running them on max speed off of the system fan controller, both resulted in much better better cooling and reduced noise levels.
I did 3 Arctic p12 max and dropped a few C. The merc310 makes this annoying "rattle" sound with stock fans at high speed, and it's even worse with the p12s. I suspect the fin design is making this noise due to increased airflow and pressure. I went back to stock for now.
Imagine you buy 1000+bucks gpu with massive cooler nad Vapor chamber, 3 Noctua Nf-P12 fans in order to have perfectly silent gaming PC and when you launch game you get a coilwhine 😭😭😂
It’s there marketing campaign to deliberate make them ugly because they perform so well; “performance over aesthetic”. Although they have all black ones released now.

I’m not gonna ever do this but I can appreciate valuable effort when I see it
Wish a partner produced cards that came naked with their own fan mounts to add fans of your choice out of the box. It would be popular.
I remember thinking that same thing! They should come with their default fans/shroud and then also include 120 or even 140 mm brackets.
@@shacacoora same, there should be a "diy GPU" model with memory pads and cooler with fan mounts optimized to actually use case fans effectively

I just used two "Y-cables" that came with the Noctua fans. But yea its pretty much the same thing.
Wonder What could be the results by replacing Noctua's with Phanteks t30's🤔(Aslo they can do 3000 rpm).
t30s don’t even get much cooler while having significant noice to perfomance issues
Noctua has 3000rpm they’re called ippc 3000.
Cool idea. I wonder what screws did you use for this? The ones already present from the original XFX Shroud?
looks like an3d printed fannshroud plate
