Fan header failing on H80i v2?

Hi,

Noticed in the link software that the fan RPM for my H80i is 0, I opened my case and the fans were spinning but would stop. I disconnected one of the fan from the y cable and plugged it into the fan controller I have so I at least could make one fan work constantly.

 

The Pump for the cooler is at 3000 rpm, I also double checked my bios to make sure that the fan controller was set to 100% full speed thinking it might be the 12v issue, though from what I understand that would also mean my pump would only operate at 600 RPM.

 

If I manually change the fan profile to max, I can hear the fan spin up and run at max speed but the software still only shows at 0 RPM. Given the Pump is working at 3000 RPM and the current temperature of the system I should be safe to assume that the cooler is still pumping liquid around?

Regarding the fan header, what would be the best course of action? My H80I was purchased in 2017, so it should still be in the 5 year warranty period, so do I just take it back to place of purchase or do you have any test I can run before hand?

It's possible the internal fan controller is starting to malfunction. A key differentiating factor would be if the fan(s) seem to spin up randomly, stop, or are generally uncontrollable on the H80i v2, but work perfectly on the MB header. A fault in the PWM or tach wire on the fan could also cause these symptoms, but would be present on both the H80i v2 and MB headers.

 

If the pump is at 3000 rpm, then you have the full 12v. The cooler is still working and moving fluid. If not, you could watch that H80i v2 temp tick upwards +1C every few seconds until shutdown. 26C is a pretty low coolant temp and you are in good shape.

 

The H80i v2 fan controller uses a two way splitter for one control channel. That means one end of the splitter has 4 pins (controlling) and one has 3 pin. If you are testing functionality, make sure the fan is on the 4 pin header. To that end, you can test the fan vs controller if you have any other PWM fan lying around. Connect it to the 4 pin end of the splitter and it should spin up and register in Link. Obviously the failure of another fan to properly spin up and report would be a strong sign there is an issue with the AIO's controller.

 

Contact Corsair support through the Ticket Support System link in the header above. Warranty procedures vary by locality, so I can't tell you if you will be mailing it back to them or taking it to the shop. Typically North America and Western Europe mail it back and most of other locations work through the local dealer.

Thanks,

I also removed the link software as well and installed icue as a test

The fan still showing as 0 RPM, but running at 100 percent, I can not change it at present in the icue software, yeah I have 4 fans all the same in my case, I will swap the fans around a check the 4 pin header on the cable as well to make sure it is all working.

 

Thanks for that

Yeah so, I put one of the fans to the fan controller moved the other fan to the 4 pin header and it is now working in icue

Thanks for the help

It could be just a kink in the tachometer wire on the original fan. That can go on the 3 pin where the tach pin is missing and both fans will still respond. Controller issues were really rare on the GTX/v2 series, so I am glad this was an easy fix.
