ryouga Posted June 25, 2020 Share Posted June 25, 2020 (edited) Its only a few weeks old, took pc apart as added LL140 fans spend 2 days having issues. Today got the LL140's working but now the aio pump isn't working, when SATA is connected the fans blast out at full speed but the leds on the fans and pumps show nothing and temps are 60-70 c on idle. Tested on different sata connectors, molex to sata all same fans run at full but no power to pump. No damage to sata cable at all. I also tried different motherboard headers, nothing but those headers work fine for fans. Could my testing of multiple power on/off cycles in quick sucession of killed it quickly? EDIT Sorry H100i RGB i'm on a tablet pc so hard to type. Edited June 25, 2020 by ryouga Wrong model number Link to comment Share on other sites More sharing options...
c-attack Posted June 26, 2020 Share Posted June 26, 2020 Is the cooler displayed in iCUE? What is the coolant temperature (H100i Temp.)? When you first boot up, are the cpu temps already at 60-70C or do they slowly build to that level? Link to comment Share on other sites More sharing options...
ryouga Posted June 26, 2020 Author Share Posted June 26, 2020 Temp ramps up in about 3-5 minutes, I did 2 other tests, if I remove the usb header the fans stop spinning, or if I remove the sata power connector the fans stop (probably logical) Not recognised by iCUE at all, it was the day before and it updated firmware.

c-attack Posted June 26, 2020 Share Posted June 26, 2020 I would contact Corsair support. It seems most probable there was some kind of electrical failure in the unit. The slow temp ramp up is a classic low or no flow indicator. Combined with a complete lack of recognition supports that and unfortunately there isn't a user remedy. I don't quite understand the fans shutting down when the USB plug is removed. That should not happen under any circumstances, but perhaps a side effect from whatever happened. Sorry, I don't think there is much you can do. Link to comment Share on other sites More sharing options...
