Disassembly/teardown:
The upgrade:
Parts:
The screws i had did not fit through the VRM mount holes and the head did not fit in the backplate
Used a grinder on the screw heads and drilled out the backplate so the screw would go through it (screw fit through the PCB no problem)
Edited the vBIOS to make the fan curve ramp up sooner if I left it stock it would never ramp up at all as the card tops out well below the stock target temperature
now here is some odd fan stuff I figured out:
oddly when using a LNA with my NF-A4 PWM i have a couple different LNA SKUs, using one resulted in a max of 4700 and the other make it drop to 4500 with 100% PWM, not the expected 3800 max
- Arctic Cooling Mono Plus
- Noctua NF-A4 PWM fan
- Aluminum (16 and 18 AWG)
- Copper (24 AWG)
- Cable Sleeving
- Heat shrink
- Fan header (female) + pins
- A ADWITS [ 6-Pack ] Thermal Pads
- 3M stainless steel screw kit
- 2x 20x20x10mm black anodized aluminum heat syncs (not in use yet, waiting on international shipping)

now here is some odd fan stuff I figured out:
- PWM % is changed by the card selecting a desired RPM, there is no way i can see to change the min rpm in the vbios editor (the max is changeable)
- Arctic fan at 0% PWM = 100% speed, unless card is receiving sense from this fan this does not apply and the fan will from at the min rpm the card allows (not the fan's min)
- The NF-A4 PWM has support for 0 RPM mode
- If the arctic fans sense is plugged into the card the rpm range you end with with a very small window of speed control as the min is 1100 rpm
