CRJ Micro 4-Pin GPU Fan Header Adapter Cable - 12-inch (30cm), Black Sleeved - Male Micro PH (2.0mm) 4-Pin PWM Fan Header Adapter for Graphics Card Fans and Pumps

This cable is perfect to externally power the built-in fans of my Zotac 5090. I got three. The micro female end of this cable is connected to the card's fans. The larger 4 pin header is plugged into a multiheader fan controller with turn knob voltage control (powered with 12v smps). Works as intended. I'm extremely happy that this cable is available.

High quality connectors and nice braiding on the cable

This will connect the fans of a Steel Legend Arc B580 GPU to an Asrock motherboard fan header.

The cable itself is put together well, as you'd expect, with sleeving and heatshrink on the ends. However, if you're modding a GPU AIO, be very careful (and pull out a multimeter). The wire colors line up, thankfully, but are reversed from the AIO pinout on a EVGA 3090.. and from a normal fan cable, as you can see in the picture. Maybe this is normal for old mini connectors (seems stupid to me and doesn't make sense), but it is not for a newer card. I installed this backward on the mini side.. eventually, after much trial and error, and finally pulling out a multimeter. The clip is very hard to get in in the "correct" orientation and also very hard to get out. But it is super easy to get in reversed (the way I installed it eventually), but also gets unplugged super easily (one of the many problem runs I had). You'll need to tape it or wedge it in somewhere it can't come unplugged. I confirmed that the mini plug on the AIO pump had a normal pinout, following standard fan headers, with ground (black) on the "left" of the plug and pwm (blue) on the "right" of the plug by testing from the plug to one of the fan headers coming off the AIO, which are a standard layout, even though they're all black. Maybe I got a dud and someone installed all the pins backward that day. I don't know. But just be careful you test before going full bore and ruining your card.

HI all, The sole reason I purchased this cable is to fix the stupid pump and fan design by EVGA for its 10XX and 20XX hybrid GPU's. For some reason EVGA has decided to use 1 cable to control both the pump and the fan speed. I have a pretty silent build at idle except for that annoying pump noise running at 100% all the time. With this modification I can now control the pump speed and the fan speed separately. I have the Pump running at 40% on idle and boosting to 100% during load. I cannot hear the pump. my temps have not increased. Still under +35C from ambient (60C) at full load. and during idle its sitting at +6C. EVGA should include this $6 cable with their pumps honestly As for the cable itself, It is a nice braided cable and both ports are solid. There is no wiggle room, the ends fit snug in their appropriate ports. Again do yourself a favor. If you have an EVGA hybrid GPU get this cable.

I have a rig that is still running RX570 and RX580's. One of the cards for some reason stopped sending a steady voltage to the fan output and the fans stopped working. Replaced with more fans thinking they had gone bad and still dead. I tried this adapter to plug the fans into the mobo or molex adapter and the "dead" fans worked perfectly. brought the rig back online, and random reboots and hardware errors have completely stopped. Rig is running better than it has in a very long time. I will order more to have spares on hand.

I didnt want to use a PCIe cable just to power my cards fan. I bought this cable and it was plug n play. My motherboard came with some thermal sensors and I used it on my M.2 drives on that card and the motherboard controls the cards fan via this cable and the thermal sensors. The cable was made very well and its a good product. One thing I would recommend to do is check the pinout of both devices.

Had a 6900xt toxic that I grew to actually hate, a repaste and this cable mod allowed me to set the pump to what it should be, voltage control instead of pwm. Always run asetek pumps in voltage. Go ahead. Try it on your cpu and put your ear to it on both modes. You'll notice a great difference. Put it on silent or normal mode under voltage control and enjoy your card the way it should have been from the factory.

Can adapt to Xbox cooler fan and works good

Connector is not all black. One end is white. Don't expect all black if u order this.

This is an awesome cable. The braided sleeve is solid, and the connections don’t feel flimsy at all. Used to rebuild an old 1050ti, works better than with the original parts.

It is not a micro 4 pin to 4 pin PWM but a 4 pin PWM extension.

not the same cable as they described. i needed a crj micro not fan to fan
