Pocah Posted September 2, 2020 Share Posted September 2, 2020 (edited) I use iCEU, heaven help me. I can't for the life of me get it to change my pump speed. I am using a H115i. No amount of left clicking, right clicking or anything else allow me to change it. Talk about non-intuitive! Can anyone tell me how to change it? Oh, It seems I can set it to quiet or extreme but not balanced. Shame that really, I find quiet a little too passive and extreme, well, extreme!

c-attack Posted September 2, 2020 Share Posted September 2, 2020 Click on the "Quiet" or "Extreme" preset. It should turn yellow. Then click on the pump RPM reading to the right. It will ring yellow to show it's applied. The names don't mean anything and all Corsair coolers use a 2-3 fixed pump speeds. For your cooler, that should be around 2000 on the low and 3000 on the high. Most people will not see a benefit by using the higher speed. Link to comment Share on other sites More sharing options...
Pocah Posted September 2, 2020 Author Share Posted September 2, 2020 I'm very puzzled because it made a huge difference. It probably took about fifteen to twenty degrees off the CPU. I am wondering if there was an air bubble stuck in the pump or something. I will try switching it back to quiet ( 2000 ) and see what happens.

Pocah Posted September 2, 2020 Author Share Posted September 2, 2020 Yes, it's weird. Switching it back to quiet it's recovered in that it is now cooler than earlier results. I am not sure what happened. There is a difference with extreme but it's perfectly acceptable at quiet. There was a significant difference earlier which makes me think that perhaps there was a bubble trapped in the pump or something that cleared when I switched it to extreme, unless you know of some other issue that might have caused this.

c-attack Posted September 2, 2020 Share Posted September 2, 2020 (edited) It should never make that kind of difference. If you start to see consistent 5C+ changes in static conditions, it likely means you have some type of flow restriction. In response to your other question, the pump burning out or mechanically failing is not very common. More frequently you run into a slow degradation over time. Keep an eye on the H115i temp. Change the speed at idle when the CPU is outputting a minimal amount of watts. Consistent change in coolant temp there likely indicates a developing issue.

Pocah Posted September 2, 2020 Author Share Posted September 2, 2020 It seems to be stable now. I think it probably was a bubble. The PC was moved yesterday so I am guessing that's what caused it. Anyway, I will do as you say and keep an eye on it. It's certainly working well right now. Thank you for your help :D Link to comment Share on other sites More sharing options...
