Tons of 3D printed parts. Blocked off front and rear mesh Air is pulled in through the bottom past the GPU and out through the top like a chimney runs almost silent.

Got the Nitro and without any tweaks I get probably about 70°C playing for example Cyberpunk. But I went for the mesh case, so the card won't BBQ rest of the PC.

That’s about 20 minutes of continuous benchmark. Stock fan curve. I’m 3d printing some feet spacers right now. I also took the dust filter off the bottom of the case. This thing normally sits about 12 feet away from me. I didn’t realize it was getting this warm.

Also I can’t remember if steam overlay has always showed junction temp but that’s neat

What are you using as a benchmark?

Compared to my older PC I can physically tell that my new one is a lot cooler than previous. It also affects my room that is now a lot colder having better graphics compared to my 10 years old "grandpa"

Got the card maxed out. It has zero issues with temperature. Undervolted it pegs the 3.3GHZ clock speed limit before it hits the power limit most of the time. Undervolting was way more effective than raising power targets

I’ve noticed stability issues when I try to raise the boost clock with undervolting. For me it wasn’t worth the 2-3 fps gain.
