K70 RGB, K70 RGB PRO, K70 Lux RGB, K70 RGB Rapidfire, K70 RGB SE Rapidfire, K70 Lux, K70 Rapidfire, K70 PRO MINI Device path: \\?\SWD#PRINTENUM#{8491291A-B61F-4C9E-AED9-7D2BB2AE8FBC}#{0ecef634-6ef0-472a-8085-5ad023ecbccd} I have tried applying the curve following your indications, resulting in the image I attached. The screenshot was taken just after starting the computer and running ICUE, and as you can see the cooler is at 33ºC. They need to replace the controller h/w & s/w on the pump unit. Clearly the way it is designed today does not allow it to manage the fans properly or are the LED's reliable or provide a dedicated USB device interface (not a cluedgy HID).

Now that the unit is mounted, we will want to plug in power cables for both of the fans and the pump. The H100i has an integrated 4-fan hub which is where you will want to plug in your H100i fans. You will find two ports on top of the cooling unit, where you can plug in the included fan power adapter cables. Each adapter will support two fans, and by plugging the fans directly into the fan power adapter cable and into the cooling unit, you will be able to monitor and control the H100i fans through the Corsair Link V2 software.

YOUR SETUP AT YOUR COMMAND

If you want to see diagrams or more detailed installation instructions, consult your cooler product manual. If you cannot find your product manual, you can use this manual for the H100i Platinum. There may be legitimate or uncontrollable reasons your coolant is at 40C without load, but this is what we need to focus on. For now, you can get around the max speed by creating a custom curve as suggested originally. Those will not jump to 100% when you hit 40. The Corsair Hydro Series is a good product.”}},{“@type”:”Question”,”name”:”Is the Corsair H100i v2 RGB?”,”acceptedAnswer”:{“@type”:”Answer”,”text”:” Note: the screenshots below come from Windows 10, and the fixes also work in Windows 8 and Windows 7.

It's fairly difficult to keep piling on heat with the fans at maximum, at least from CPU heat. What were you doing at the time? If you heat the case up with the GPU, you might see this. Not related specifically to fan control, but it would be good to figure out if there is something wrong with the cooler. What kind of room and case temperature do you have? When sitting at idle on the desktop, what is the coolant temperature? Does it stay level or slowly creep up?Thank you very much for your answer, I think that it is solved for now. According to your reply, I set the 100% rpm to the 50C, achieving that the fans run more deccelerated and less noisy. So if 39C is your typical baseline coolant temperature at idle, set that to a comfortable fan speed. Start to ramp it up to moderate levels from +3-6C and then put a high speed flourish around 50C to let you know unequivocally things are getting hot without the need to stare at the software. My room temperature is pretty hot, 39C could be the currently temperature in the cooler. Without ICUE, the fans work perfectly no matter what is the ambient temp, accelerating and decelerating according to the game im playing. But with ICUE, the fans speed up even if the ambient temperature is cold, just to start the program. I have a H100i v2 cooling system, and it has been working perfectly with Corsair Link 4 Software. Also, I own a K65 lux RGB keyboard working with Corsair Utility Engine 2 Software. If you want i may give the firmware 1.0.4 to you as I have it but trust me...it is really better you stay with 1.0.0 and hope that gurus here are saying the truth.
