Noctua fan mod turns an unusable RX 5700 XT GPU into a beast

Audio player loading…

It turns out that a whole lot more of you were into the Asus X Noctua RTX 3070 (opens in new tab) than I had expected. Good on you, it's a beauty. So with that in mind, let me turn your attention to this creation by serial overclocker der8auer: their very own AMD RX 5700 XT Noctua Edition.

Modded, of course.

It all starts with an AMD Radeon RX 5700 XT, and one that has seen better days after being left in, well, dirt, apparently. Don't worry, though, this card will get a major glow up by the end of the der8auer video (opens in new tab), which you can check out above.

The original shroud is removed and replaced with a custom machined model made out of aluminium. It's wonderfully satisfying to watch a GPU shroud carved out of a solid block of aluminium, too. This new shroud is in keeping to the original specifications, though, to preserve some of the card's DNA. 

The squeamish among you may want to look away after that because der8auer runs the card under some tap water for cleaning. Don't worry, that's not actually an issue if there's no power stored in the device and it's cleaned extensively with isopropyl alcohol afterwards. It looks wrong, but der8auer knows what they're doing.

Then it's time to mount the Noctua fans, which are lauded for their operational efficiency and acoustic performance. Der8auer has chosen NF-A9x14 HS-PWM fans for this mod, which are notably smaller than the NF-A12x25 fans found on the Asus X Noctua RTX 3070.

They're also notably less brown (opens in new tab).

Onto performance, then, and der8auer notes that it's actually not the quietest card ever, nor the coolest. The graphics card hits an average temperature of around 81°C, and the memory sits at around 70°C. 

But that's not the last word in temperatures. Through some additional washers, der8auer was able to place additional pressure on the heatsink and compress the thermal pads further, which made better contact and resulted in GPU temperature dropping to 69°C.

I genuinely love this mod, though, if only because it's a totally different take on a Noctua-cooled graphics card to the Asus X Noctua RTX 3070 recently announced. As to which one looks best? I'll let you be the judge.
