If it's so detrimental then Corsair should't let the pump sit at 1000rpm regardless coolant temp. The main selling point for H115i/150i Pro is it being quiet, how can that be detrimental for anything more than web browsing. I run a quiet system and there's a very audible whine from 2000rpm+ that I find distracting. The pump in quiet mode is inaudible and I get decent coolant temps (~35c) for casual gaming so that's where I keep it.

I had the same issue with my H115i Pro pump jumping between 1000 and 2000rpm when the CPU usage goes up. I think it might be a bug in iCUE because if I use Corsair Link, the pump stays on quiet (1000rpm) regardless of load.

I managed to resolve the USB sound which I think is actually a connect sound, by connecting the AIO directly to the motherboard USB header.

Probably a bit late but I’m having the same problem on the latest version of iCUE. It seems to work ok on the latest version of Link.

Hi DevBiker. I have posted some of my concerns with iCUE in another thread called "iCUE 3.15.101 - Feedback" Another difference and this is on my system, iCUE uses about 10% CPU when I have the dashboard up and 5% with the app minimized. Link uses 2% open and 1% minimized. I really hope you guys will reconsider keeping Link going. It's superior in performance.

Good question. I just ran Prime95 and the pump does then jump to 2000rpm In Link the pump would stay at 1000rpm when set to quiet. Is there a way to lock it to 1000rpm in iCUE? One more thing, in Link if I choose one of the default fan profiles (quiet, balance, performance) I can still change the temp sensor source. In iCUE this doesn't seem to be possible. And one suggestion. It would be very helpful to access fan/pump profiles from the dashboard. Again this is possible in Link and reduces a lot of clicking and back and forth. For now I'm sticking with Link.

The pump on the H115i Pro is set to Quiet but would randomly jump to Balanced. I can only tell because I can hear the pump suddenly ramp up the rpm. iCUE shows it jumping between 1080 and 2000rpm When I run Link it doesn't happen.

I can appreciate that, it's just that I was under the impression the CoPro would give me full range control over my fans which doesn't seem to be the case. I could swap my fans to PWM but that increases overall cost.

Thanks DevBiker. I did some testing with a spare Silent Wings 2 PWM fan and was able to drop it to around 25% whereas the Phanteks DC bottoms out at 42% If I connect the phanteks directly to the motherboard fan header, I can also drop to around 31% - which seems to be the minimum needed for the fans to spin up again from zero rpm. Why is it that the CoPro cant drop below 7V?

Just installed the Commander Pro into the Evolv X case. The case has 3x 140mm DC fans and the lowest RPM (apart from 0) which I can get using iCUE is 580. When I connect the fans to Phanteks fan hub via a fan header on the motherboard, I can spin them down to 370rpm Is there a way I can replicate this using the Commander Pro?
