Very informative thread, thanks guys.

I saw all your good feedbacks about riserless motherboards so I purchased 2 Onda 6 GPU boards from Alibaba. They work like a charm but i'm struggling keeping them inside a closed case with a low CFM fans, GPUs are heating too much.

I tried to use some spare Deltas 252 CFM fans, but I can't find in BIOS how to lower fan header voltage in order to decrease the RPM and consumption.
I don't want to keep them at 100% because of noise and don't think the motherboard can handle 3 fans at 3.9A each.

Any ideas?

just buy an external manual Fan regulator. it usually needs a 4 pol molex power

smth like this https://www.amazon.com/HDE-Channel-Multi-Fan-Cooling-Controller/dp/B006UFMH3W/ref=sr_1_7?ie=UTF8&qid=1515507033&sr=8-7&keywords=fan+control+pc

I know about these fan controllers but most of them can't handle more than 2A per fan header.

There are adapters that will let you run a high-wattage fan from a MOLEX for +12VDC power with a second header for the PWM control and RPM sense functions.
