Monitor Cooling Fan Spoofing

PWM Fan Simulator/Spoofer

Monitors listen for the fucking tachometer on fans, or at least LG monitors do. Lowering the fan's duty cycle in the debug menu on LG monitors only persists until power cycle, making this solution useless. I figured out a workaround.

These spoofers appear to be sold for bitcoin minters? Find one, doesn't matter what connector is at the end because you have to splice it regardless. Here's an example of one.

The wire colors on the example follow the standard PWM pinout. With this you can see the pinout for the spoofer itself.

Next, look on the fan from the monitor itself at where the wires are soldered to the fan's pcb, the pinout should be silkscreened on.

Cut the plugs off the fan and spoofer, and splice your spoofer to the fan's plug, reinstall, done.

Buying Guide

What Panel Type to Buy (2025/2026)

Until MicroLED arrives, we're stuck with 2 options. OLED or LCD. I do not care about any LCD panel that is edge lit, or any panel that isn't fastIPS.

OLED

Cons

  • Flicker
  • Minimum grey brightness (varies panel to panel)
  • Burn in (is a fact)
  • Color shift (another effect of burn in)
  • Poor brightness
  • Sub pixel edges are visible / layout is bad
  • Colors can look horrible on certain panels

Pros

  • HDR actually works
  • Latency is basically zero
  • Refresh rates are outstanding

QD-OLED and WOLED are both available options. WOLED atow is just done by LG.

MiniLED (NanoIPS)

Cons

  • Awful black levels
  • HDR is useless (blooming etc)
  • Not many options out there (OLED is taking over)
  • Latency + refresh is nowhere near OLED

Pros

  • No burn in
  • Sub pixel density rocks (text clarity is insane)
  • Colors look fantastic out of the box

SubPixel Density

If you're using your monitor for stuff besides games and tv, then text and overall clarity matters a lot. go on RTings for a monitor you're looking at and scroll through their review until you come across the subpixel layout data, they'll have a closeup picture of it for that monitor. This is the main metric I used to pick my monitors.

Price Ghouling

Buy monitors used every time. Look around amazon and bestbuy used listings until you find what you like. Never pay full price for a monitor, they also go on sale all the time.

Bandwidth (Port specs on display AND GPU)

I am going to assume 4k144hz minimum. This means you need at LEAST HDMI 2.1 on both your monitor and your GPU. If you want 4k240hz like on OLED panels, you need DP 2.1 on your display AND GPU. Only Nvidia 5000 series+ has DP 2.1. If you don't have the bandwidth required then you're going to either be running in a limited capacity, or you'll be using displaystream compression, which was so noticeable to me I didn't even know what it was and I was debugging why my side monitor colors were fucked up on the same panel model.
