HI guys, so I built my first PC yesterday and after booting up, installing app, windows, etc, everything was perfectly fine and working as intended except for my cooler and the temp. I followed the instruction, the cooler is lighting up inside my case but the cooler fans aren't turning and my pc temp Hit 67C while I was installing some low data apps like spotify or skype....

Also, I keep hearing the windows device connect/disconnect notification sound each 10 seconds, so I looked up in my devices and I kept seeing the corsair USB appearing and disappearing, is this because of the corsair link usb cable ? ( the link app was showing me my CPU was at 120C LOL which is impossible...)

So I was wondering if I installed my cooler the wrong way ? I will step back what I did:

- installed the cooler on top of my ryzen 2600x with the AM4 socket since I have a x470 gaming plus ( I reapplied thermal paste and cleaned the one that was pre applied)
- installed the radiator and the 2x fans as exhaust on top of my case
- now it's where im not 100% sure, I connected the cooler power cable to the CPU_FAN. After there is a "Y" cable that comes off the Corsair cooler, So I connected 2x cooler fans to the Y cable.

I even looked the manual and everything seem to be in order, but I looked at my fans when I was installing apps and the case fans were working fine ( 1 intake installed on the SYS_FAN2 and 1 exhaust installed in te SYS_FAN4) but the 2x cooler fans were not turning at all and I kept hearing the annoying device connect/disconnect sound...

Need your help on this!! thanks a lot :)
 
Solution
At this point, we just need to know if it's the Y-splitter. If you have a CPU_FAN and CPU_OPT header use those. The problem with suing other fan headers is that they don't throttle up properly when the cpu gets too hot. You could change fan curves, but then the entire system would be permanently noisy.


I own a Corsair headset and it has a mini usb cable to recharge the headset. I even tried to change the placement of the cable but it stills does the connect/disconnect sound.
 
OKAY SO:

I JUST saw that my "y" cable had a pin missing so i connected everything separately.

Usb sound was still going and my temps was at 70c

AFTER THAT i went into my BIOS and saw the cpu fan at 0rpm ?!?!? So i PWM it to max and... BOOOM CPU temp at 30c right now

I can see the PWM option i clicked, but I cant see my cpu fan voltage ?
