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

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.

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.

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 honestlyAs 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.

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.

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.

I got this because I needed a mini 4 pin adapter, as in a converter from the ACTUAL mini 4 pin connector on my cooling fan. Long story short, this looks like just an extension cable or a cable for pins that may be SLIGHTLY smaller than the pins on the mother board. I needed an adapter for my zalman (the one that came with it was lost by my son). I ended up just buying a new zalman cooler for the adaptor (I'll also have a secondary cooler in case the one currently on dies) versus trying to buy every adaptor that says "male mini 4 pin to female 4 pin". I've included an image. I still left 5 stars, because it's a perfectly good cord... I just cant use it.

My video card no longer controlled the fans for it but otherwise worked great. The fans worked so the card itself was the issue. instead of buying a new expensive GPU, this allowed me to use a mobo fan header to make the fans work. set the duty cycle to 80% in the bios and used FurMark to stress the GPU to make sure it wont overheat when on full load.

Wow, this review cannot explain how much relief a simple little cord has brought me, sweet sweet silence on my pump on my gpu aio watercooler. Solved the evga hybrid pump noise perfectly now I just have it set to a thermal sensor I placed on the back of the card to control the pump curve through bios!
