How it Works

fan Sniper fixes what most PC fans fail to do, STOP... Your GPU fans have 0db aka Fan-Stop mode, why run the fans when there isn't enough heat to bother? The fan Sniper gives this same functionality to any PC fan you like.

stop my fans you say?... 🤔

We build our rigs to take a beating from some of the toughest games and applications out there, but when we just surf the net or whip up a quick meme, even the lowest of idle fan speeds isn't really needed. Most water cooled PC's can run with only one or even no fans on during these casual tasks. Maybe you only want to snipe some of your fans, you can use the fan Sniper on a single fan, or using the PWM fan splitter you can power as many fans as your motherboard header will support, or use the SATA powered breakout cable to power up to 2 Amps worth of fans!

The fan Sniper was specially designed for custom built PC's by PC builders, these are just a few solutions the fan Sniper provides:

  • check box icon Lower noise level.

  • check box icon Less dust and dirt inside your sweet rig.

  • check box icon No startup clunky noises like when you use the bios DC setting on a PWM 4-Pin fan.

  • check box icon No twitching fans or burnt up fan motors like when you use the bios DC setting on a PWM 4-Pin fan.

  • check box icon Built-in short circuit protection for your motherboard or fan controller.


How does it work & What are the hardware requirements?

Your motherboard or fan controller must support fan curves that go to at least 5% output at its lowest PWM setting. Most PC fans wont obey a PWM signal below 35% and most will just spin at their minimum rated RPM. Some people get around this by setting their motherboard bios or fan controller to DC mode on their PWM fans, then use fan curves to lower the DC voltage to the fan. Though this kind of works, it causes fan motor heating (voltage to the motor while stalled), twitching at low speeds, and noisy startup from a stop.

The fan Sniper does it right and monitors the PWM signal, once the PWM signal falls below 25% or so the fan Sniper will cut the 12v power to your fan totally. No heating, no twitching, no clunky startup, no default idle speed, no special 0db/fan-stop fans needed, just a powered down silent fan that you control via your normal fan curves.

Here's the loot!

It's up to you to pull the trigger on one of these sweet fan Snipers.
