Setup

Fan Control

ARC Raiders A4-H2O Fan Control Idle

I use FanControl for managing the AIO fan speeds.

The config file for this particular build is available for download on my Patreon, but you can follow the tips below for setting up a similar config.

Configuration

Because the AIO fans are also the only exhaust fans in this build, I want them to ramp up based on whichever component is running hottest.

Check the steps below for an outline on how this is done.

Steps
  1. Set up a Mix custom sensor with the Function set to Max and name it CPU vs. GPU.
  2. Create a CPU Offset custom sensor with the temp. source set to the CPU Core (Tctl/Tdie) sensor and an offset of -15. This is done in order to “align” the generally higher CPU temperature with the lower GPU temperature.
  3. In the CPU vs. GPU custom sensor, add in the CPU Offset sensor and the GPU core sensor.
  4. Create two Graph curves, one for the AIO fans and (optionally) one for the AIO Pump.
  5. Set the AIO Fans Graph fan curve temp. source to the CPU vs. GPU sensor
  6. Set the AIO Fans control card to the AIO Fans Graph curve

Customize the graphs preference. Here are the minimum and maximum values I’ve used for setting up this particular build, assuming you are using the stock Silent Loop 3 fans:

  • AIO fans: 30% up to 53°C, maxing out at 70% above 75°C.
  • AIO pump: 40% up to 62°C, maxing out at 80% above 75°C.

Set up the intermediate “steps” of the curves to your preference, but I suggest a 62-64% fan speed target as an upper limit for most usage scenarios (outside of extreme cases, of course)

Tuning Apps

MSI Afterburner - The industry standard overclocking / undervolting software. Cannot live without it.

Riva Tuner Statistics Server (RTSS) - Bundled with Afterburner. My go-to tool for setting up frame rate limits and for in-game overlays.

Overlay

ARC Raiders custom RTSS overlay

This RTSS overlay is available exclusively on my Patreon.

It supports most of the popular screen resolutions (including ultrawide), and multiple CPU thread counts.

It uses RTSS sensors exclusively, so you don’t have to run any other apps in the background.
