MEIRIYFA3 Pin 4 Pin Fan Adapter PWM PC Chassis Cooling Fan Hub 8 Way Splitter DC12V Speed Controller with 6 Pin Power Port,Chassis Fan Pressure Regulating Governor

I have a server motherboard with 2x AMD EPYC 64c, Noctua double cooler for each cpu using all day long with 98% of load for data mining. My CPUs usually were 80-82 Celsius degrees, after Install this device and push to max rotation, my CPUs temperature were down to 73 which is very good. 100% recommended. saved me $400 buying 2 liquid coolers.

Excellent and inexpensive fan splitter and speed controller for PWM case fans. Easy to adjust the fan speed with a flat blade screwdriver.It comes with double sided tape attached to the back which works provided you are careful in how the 6 pin power cable is placed. The weight of that cable in a case can be enough pull the board loose over time.I do wish there was at least one mounting hole so I could securely attach it to a standoff.

A lot of motherboard manufacturers force customers to install what is effectively adware to control fans. (e.g., We'll ask if you want to install Norton Antivirus "free trial" again, even though you declined the last 10 times.)These little wonders allow you to take back control of your fans without the bloat and annoyance.They're especially handy if you want to run a quiet build with fan speeds that consistently run without noise.

BUYER BEWARE: My device arrived DOA. I tested with multiple power supplies and the onboard LED does not illuminate and the connected fans do not have power.I didn't get the opportunity to test until now and I am bit more than a week out from the return window.

Used for a Dell Optiplex SFF case swap so the motherboard could be used with a large GPU. MB only had one pwm fan header for the CPU fan. Was able to add 2 case fans that turn on and off with the computer and which speed is adjustable. Plugs right into the 12v 6pin plug from the aftermarket PSU. No need for SATA power. Solved many problems at once. We'll see how long it holds up.

Easy to install and gives you the ability to power multiple fans, but the speed control knob does not work with Supermicro fans.

I'm using this in a 4u atx pc build. If you want a high wattage static rpm fan controller, this will get the job done. It has plenty of wattage to power multiple high wattage fans. That being said, this is not a smart contoller, it does not output a PWM signal, its just a potentiometer with fan headers. Nothing more, nothing less.It works great for my use case, cause I just wanted a couple of fans to run at a static rpm. If you are looking for something that can match a motherboard fan speed, or constantly change rpms this is not the product you want. This is a dumb "controller" and it does exactly what it should. I've had mine installed for over a year and it has worked flawlessly.
