## Description



## Features

- Simple Installation - Dielectric oil or 3M Novec immersion provides a cooler environment and more stable system performance. This small device emulates fan presence in systems with no need for fans
- No Coding - Just plug in the fan simulators and the miner thinks it has control over fans that do not exist. A simple plug and play option for anyone looking to start immersion cooling
- Easy Emulation - Plug the emulator into the primary fan port and it will send a tachometer signal to the miner's controller (tricking it into believing fans are attached and working within parameters)
- Quality Components - Each emulator undergoes a 1 hour performance test to ensure product quality. The device reports fan speeds up to 8000 RPM
- We’re proud of the products we sell. If the Fan Simulators fail to meet your expectations for any reason, we will go the extra mile to make things right.

**Q: Any idea if this will spoof a model t129215sh fan.  12v 0.3a with ~2000 - 3200 rpm?**
A: It works on all of the miners I have and have had only suggest you use one if your cooling with external air flow the machines tend to get hot when your using them with the factory setup and configuration and taking fans off or slowing airspeed will severely reduce the lifespan of the machine but great if your doing submerged mining rig would recommend for sure

## Customer Reviews

### ⭐⭐⭐⭐⭐ They Work on Dell/Alienware Desktops
*by T***M on December 15, 2024*

I switched my small CPU fan to an AIO 240 which doesn't require the two motherboard case fan connections, however when it booted up it threw case fan errors and there was no BIOS settings to disable it.These work 100% and are incredibly simple to install. Best of all there are no BIOS settings to mess with.

### ⭐⭐⭐⭐⭐ Works on computer motherboards as well fyi
*by R***S on February 10, 2023*

I have this in a Dell power edge server that was waaay to loud for my office. I installed a fan controller but the server lights turned all orange and grumpy and was all like I have no fans plugged in. Plugged these in and everything went blue and happy. Just made this review to confirm these work on normal fan headers because I could not find that info anywhere and just went for it anyway. Glad I did. Hope they just work forever.

### ⭐⭐⭐⭐ They worked like I wanted next step mineral oil
