Lewis1190 Posted October 26, 2021 Share Posted October 26, 2021 (edited) EDIT: I'm new here, so I can provide any extra information that might be needed on-request 🙂 Hi all. I've just installed the H115i Elite Capellix 280mm this weekend on my new i7 11700k, but I'm a bit concerned with the pump speeds that I'm getting. On iCUE 4, my pump shows the following speeds: Quiet Preset: 2985 - 3000 RPM Balanced Preset: 3140-3165 RPM Extreme Preset: 3370RPM On the "iCUE ELITE CAPELLIX Faq and Setup Info" thread, OP lists that the pump has the following speeds: Quiet Preset: 2300 RPM Balanced Preset: 2480 RPM Extreme Preset: 2700 RPM Pictures below. Whilst I'm very happy with the temps I'm getting (~35C - 45C on idle), I'm a little concerned by how high these pump speeds are. I've asked in the corsair Discord and some other community members have told me that everything's okay, but I just can't understand why my pump is running so much faster than what I'm seeing described elsewhere. Could anybody shed some light on what might be happening to me here? Edited October 26, 2021 by Lewis1190 Link to comment Share on other sites More sharing options...
c-attack Posted October 26, 2021 Share Posted October 26, 2021 I would say that is not OK. There isn't a legitimate reason for it to be that far out of spec and this usually spells near future trouble for the pump. You can try lifting the end of the case so the tubes are higher than the CPU block and see if there is a sudden pressure release, but most of the time I have seen this the underlying cause is mechanical. Start a ticket with Corsair Support.

Hi, thanks for the reply. I'm not 100% sure what you mean by "You can try lifting the end of the case so the tubes are higher than the CPU block". Here's how my radiator and pump block is mounted. I have tubes going into the bottom of the pump block, with the tubes at the top of the radiator. This was the best radiator position I could do, given the size of my gtx 1070. I looked online to see if pump block tube position mattered, but I was told it didn't. So, I seated the pump so that my tubes were at the bottom of the pump block (rather than the "default" right side) to clear more space with for my RAM. Image attached. What I ALSO find strange is that my preset RPMs appear to be 660-685RPM different to EACH of the "expected" pump readings. Not sure how I could explain that . Could you please elaborate on how I would "lift the case", given this setup? Edited October 27, 2021 by Lewis1190 Extra info Link to comment Share on other sites More sharing options...
LeDoyen Posted October 27, 2021 Share Posted October 27, 2021 you could try to lift the whole case, the whole PC 🙂 , and rotate it to have the radiator facing up, and maybe try going even further to help any eventual trapped air to exit the pump block. The way the pump is installed doesn't matter greatly but AIO pumps aren't exactly powerful, so upon installation, depending where the tubes are, they may need a little help to get air out the first time 🙂  Link to comment Share on other sites More sharing options...
c-attack Posted October 27, 2021 Share Posted October 27, 2021 As above. You would need to rotate the case almost 90 deg so the front end is up in the air.  However, that only matters if there is air in there and that almost always comes with gurgles and other irregular noise. If you are not hearing that, there probably is no reason to try. I have seen strange pump speed shifting do to pressure, but this is pretty far outside the boundaries. The most likely scenario is a pump defect causing a consistent up shift in speed. I would contact Corsair Support or exercise exchange options with the vendor. Link to comment Share on other sites More sharing options...
