I'd read that so I'm focusing on small adjustments to the power-limit for now and observing the temperature, fan speed and, Core Clock.

I've moved the FrankenFolder to my "Data Centre," AKA the Ikea wooden shelf in the basement that houses the FreeNAS, Webserver (LAMP), ESXi (i7 NUC) and my 26-port aggregation switch, and the noise is far less noticeable from the other side of the room. Thank goodness for the inverse square law!

With the Power-Limit set to 126W (5% Boost) I'm recording: GPU temp of 76C; 84% fan and; 1936MHz clock on the EVGA GeForce GTX 1060 SC GAMING, 06G-P4-6163-KR, 6GB GDDR5, ACX 2.0 (Single Fan) P/N: 06G-P4-6163-KR (I know we're not supposed to post vendor links but I trust manufacturer links are appropriate).

This unit is producing an estimated PPD of 405,245 with a TPF of 3 mins 15 secs for an 11713 WU.

On the Kid's gaming system with a 5% power-limit and +148 Clock increases in After-burner I'm recording: GPU temp of 73C; 59% fan and; 2050MHz clock on the Gigabyte GeForce® GTX 1060 WINDFORCE 6G. The system is noticeable quieter likely due to the dual fan design. It is not performing as well as the EVGA but I suspect this is due to a older variant of the P106.

This unit is producing and estimated PPD of 393,881 with a TPF of 3 mins 18 secs for an 11713 WU.

Once I get some new button-batteries for my Kill-a-Watt I'll start taking some power measurements then dial-down the power limits and see if I can find the sweet spots for PPD/W

The Kill-a-Watt was recording 186 to 196W with a 126W Power limit. The system had been creeping slowly up to 81C due to airflow issues so I removed the side panel temporarily.

I’ve dialed the power-limit down to 80W now and with the cover reinstalled I’m running at 67C and 57% fan so the system is noticeably quieter. The Kill-a-Watt is now reading 150 to 156W and my PPD has dropped to 346,476 and the TPF to 3:26. The GPU clock is down in the high 1700s from the high 1900s.

So a 33% decrease in GPU power for a 12.5% decrease in PPD.

I’m going to just leave this running as is for now.

I got tired of the heat load in the machine and in the room. I modified the case with a four inch duct collar and installed an inline fan, ~200cfm, and vented it outside. Dropped the GPUs and CPU about 20F and the room at least 10F. A little noisy, air flow rather than actual fan noise, but not all that bad. The case is a Corsair Obsidian with four, 120mm, intake fans and one 120mm and one 60mm exhaust fan. I switched those two exhaust fans to intakes and added additional filtering as well. Not pretty, but very effective.
