[USER=29688]@mikefize[/USER] - What a great idea to use an A4000! Thank you. Who else knew an undervolted 3070Ti was on the market with an ITX pcb. Amazing. Curse me all you want, this idea is great for the SFF community.
[USER=27015]@SFFMunkee[/USER] - As I think through it - shunting or flashing vbios is probably a bit much. Let's see how far we can take the card on air.
Completed a moderate OC and comparison of the A4000 and 3060Ti Zotac Twin Edge. That 3dMark comparison data is here. YMMV, but for me ... when both cards are moderately OC'd the A4000 is 3% faster. So unless that power-limit is unlocked, it doesn't look like the A4000 can ever reach 3070Ti levels of performance. But, that's okay. It'd be pretty toasty at that speed. What's interesting here is that the DIY A4000 beats the 3060Ti while drawing
60W less (kill-a-watt total system draw 220W vs 280W) and staying
14C cooler (54C vs 68C). *All testing on an open bench.
The DIY A4000 aero is a great little card for ITX! It's just too expensive right now! Let's hope miners move away from it and flood ebay, so the price comes down and the DIY SFF builders can have some fun!
The next thing to benchmark and mod is noise. Took some readings ... the PNY aftermarket heatsink fan idles at 1400 rpms and 42db of noise. It's the loudest part of the system. When running maxed, the gpu fan hits 2900 rpms, and is making an obnoxious 50db of noise! But it is also moving a ton of air!
Up next, going to try and lower noise with a noctua mod.

Will report back with temps and noise.
