spacedyemeerkat Posted October 1, 2020 Share Posted October 1, 2020 Bought a 750i last week to replace my 650, installed with no problem. I'd pressed the fan test button after installing but couldn't hear anything so thought the button might be faulty. It powered the PC fine so I checked the PSU using iCue (already installed). It was reporting the PSU as being about 30 degrees ©, no fan activity. Continued to monitor while testing some games and the highest the temperature rose to was 35. Here's the thing: the fan never came on once according to the monitoring graph, this with the standard fan curve in iCue which appears to state it should kick-in on 40% at about 20C. I tried pushing it up to 100% at 20 to see if the fan would come on but nothing. At that point, I raised a ticket with Scan. In the meantime, I took another look at the test button while looking (instead of just listening!) at the fan. Turned out it was indeed spinning under test, absolutely silently. Brilliant :D: Here's the thing: I'm genuinely not sure whether it should be RMA'd or not. Scan replied after my update saying there's probably nothing wrong with it. I'd be fine with this if I could see evidence of the fan spinning under a custom curve but it doesn't appear to happen. I'd rather not RMA, to be honest; I just need to be fairly sure there's no issue. What do you think, Corsair gurus? Link to comment Share on other sites More sharing options...
Corsair Employee jonnyguru Posted October 1, 2020 Corsair Employee Share Posted October 1, 2020 What happens if you just turn the fan on in iCUE? Does the fan run then? Link to comment Share on other sites More sharing options...
spacedyemeerkat Posted October 2, 2020 Author Share Posted October 2, 2020 Thanks for replying. I can't see an option to do that outside of changing it to a fixed percentage. I've just tried that at 100% although I can't see a way to 'apply' it so I assume it changes 'live'. Anyway, nothing happens. Link to comment Share on other sites More sharing options...

You can have the starting RPM anywhere from 40% to 100%. If you set that and the fan still doesn't spin, make sure there isn't something blocking the fan.

Nothing blocking the fan, still works when pressing the 'test' button. RMA arranged. Link to comment Share on other sites More sharing options...
Corsair Employee jonnyguru Posted October 2, 2020 Corsair Employee Share Posted October 2, 2020 So, in iCUE, when you set the fan speed, you have to apply it by clicking on the fan tile in the middle of the screen. 1 Link to comment Share on other sites More sharing options...
spacedyemeerkat Posted October 2, 2020 Author Share Posted October 2, 2020 So, in iCUE, when you set the fan speed, you have to apply it by clicking on the fan tile in the middle of the screen. Well, would you Adam and Eve it?! It works! I had NO idea you had to click on the fan title to get it working on a custom profile. So, here's a question: under default conditions, at what temperature does the fan come on? It's not come on at all yet, according to the monitoring graph (aside from when I just activated it). I will now cancel the RMA. Again, thank you so much for your help. Link to comment Share on other sites More sharing options...
Vegan Posted October 2, 2020 Share Posted October 2, 2020 iCue still does not support HXi PSUs You will need to use Link for the PSU and iCue can monitor the PSU along with a keyboard like my cheapo K55. respect to Corsair for being budget friendly Link to comment Share on other sites More sharing options...
spacedyemeerkat Posted October 3, 2020 Author Share Posted October 3, 2020 (edited) I might be misunderstanding "support" in this case, but all features of the HX750i appear to be accessible in iCue. Edit: just tried running Link. It states the PSU is being controlled by iCue, and doesn't provide any interaction.

LeDoyen Posted October 3, 2020 Share Posted October 3, 2020 HXi always worked with iCUE.. Link is outdated on the other end and really should only be used to support legacy devices like some old AIOs that are not compatible with iCUE Link to comment Share on other sites More sharing options...
Pocah Posted October 4, 2020 Share Posted October 4, 2020 I have ( amongst others ) an RM750i and I very rarely see the fan come on. I know this is correct because from time to time I have monitored the loading in iCEU. The HX is even more efficient so honestly I would not normally expect to see the fan running at all. Even with moderate game playing. Link to comment Share on other sites More sharing options...
