AI Suite is not installed and I have Qfan disabled. The pump is definitely getting the power it needs. For some reason, my computer isn't launching the USB driver for the cooler on launch. The start up fails and I can only launch it by disabling and enabling it. When it's disabled, the cooler doesn't appear in Link and one of the fans (The four pin I think) runs at max speed, while the other runs slower. After enabling the driver the four pin slows down and Link works, but it refuses to go under 1440. The three pin cannot be controlled and continues to run slowly. After a few tests I've realised something. The issue appears to be limited to the three pin. Either fan works at 800 when connected to the three pin or the four pin alone, but only the four pin reports that speed. It's only when I connect the second fan to the three pin that the speed of the four pin increases. The issue always arises after connecting the second fan (Whichever I decide to use, it's not limited to either), and resolves once I unplug it from the three pin. It's like Link somehow isn't able to control the three pin properly and ends up setting the four pin to a higher speed. The three pin, meanwhile, continues to work at 800 (As far as I can tell based on how slow it is) and the speed of it cannot be controlled. Link correctly reports the speed of the four pin as 1440, and while it can be increased to maximum, it refuses to go under this.

I get 1440 when a fan is connected to the three pin. If I connect a fan to the four pin, it runs at 800 on quiet and I can alter the speed as normal. If I plug in the three pin by itself, it runs at 1440 on quiet and I can also control the speed. It won't go below 1440 though. That is what alerted me initially. With both fans plugged in, the four pin runs at 800 (Or abouts that, it runs much slower than the three pin) and the three pin runs at 1440. With both fans plugged in I can only adjust the speed of the three pin and it refuses to go below 1440, but works normally otherwise. Trying the PWN splitter made no difference. You also said that 1440 is rather high, but I can make it go up to something like 2900 by adjusting the speed. I'll check the exact RPM when I get home. I have the fans on a custom speed of 25% all the way through, but the same issues were present when I used quiet and the other presets. I put it on 25% initially to try to reduce the speed of the three pin and just left it like that for the four pin. The CPU never goes above 50 when gaming anyway, and that's with only the 4 pin. I have no idea what kind of temps I would get using both fans at 800, but the temperature you seen was with the 4 pin working at 800 (Or around abouts as I said, I can't be sure beyond the fact it's running slower than the three pin) and the three pin working at 1440. The thing that confused me is, if the cooler doesn't have independent fan control, how is this even possible? Because this is the reality as I'm reporting it. I can take a video if you want to see it in action.

Yes. You mean this? EDIT: I bought myself a y-splitter after finding this thread. It's a different model cooler, but it seems like the same issue. It hasn't made any difference though. The splitter I bought has a 4-pin on one end, and one 4-pin and two 3-pins on the other. I can buy one that has a 3-pin on one end and 4-pin on the other, or go for one that has all 3-pins. I might just be wasting my money though if they don't work. Even with one fan, the cooler keeps the CPU cool enough to use. It idles around 35 degrees and under load never goes above 50. This is obviously a far cry from what it would be capable of with two fans. When I tested it using both fans, the CPU ran at 21 degrees idle.

I can see the speed on the 3-pin fan in Link if I plug it in. If I leave the 3-pin unconnected, Link shows me the speed of the 4-pin fan. I get separate readings for the fan and the pump if I plug both fans in, and I can control the speeds of both no problem. I can alter the speed of the pump and lower the speed of the 3-pin fan, but it refuses to go under 1500 RPM. The 4-pin, meanwhile, just runs slowly at the back. I can see it moving if I turn my case around, and can feel the air flow at the back. The cooler works with only one fan (Push but not pull) connected to the 4-pin, and I can control the speed of it without issue, but obviously using one fan is not ideal. The cables are connected up correctly as far as I can tell. The pump cable is connected to the CPU Fan slot, Qfan is turned off, and Link is set up correctly.

Apologies if this is in the wrong forum, I wasn't sure whether it was more of an issue with cooling or Corsair Link. I'm using a Hi80 V2 liquid cooler and I'm having some issues with adjusting the RPM of the fans in Corsair Link. When I plug a fan into the 4-pin connector, it runs at 1080 RPM on quiet. I can change the RPM easily enough, and it runs at max if I set it to performance. My issue is with the second fan. When I connect it to the 3-pin connector, it immediately shoots up to 1800 RPM. I can get it down to 1500 RPM on quiet, but that's still too loud. Meanwhile, the fan connected to the 4-pin connector will run at a different, much lower speed. It doesn't matter which of the two fans I connect to the headers. I've tried swapping them around and gotten the same result. I'm using the stock four-pin fans that came with the cooler. From what I've read, both fans are supposed to run at the same speed, but for some reason they refuse to. No matter what I do, one will run slowly, and the other will run very fast. As a stopgap measure, I've disconnected one of the fans from the 3-pin connector, but that's not really a satisfactory solution. I'm convinced the issue is with me and I've just connected them up wrong or not ticked the right box. I followed the set up instructions to the letter, but something must be off if I can't get this right.
