H80i GT fans going at full speed after Corsair Link install (and uninstall)


Recommended Posts

Hi I have had this PC ten years, and never used  Corsair link software, When I downloaded and installed it the fans suddenly started going to full speed. I uninstalled it and its still the same. The CPU temps are around 42C. I have never has this problem in ten years, its far too loud

I checked the forums and notes that the software especially  Asus Suite, Fan Xpert,  causes issued but I have uninstalled that too. 

No idea what to do so any help would be most appreciated ☺️

With CUE link installed, does the AIO show in Link?  You should have fan speed control and that’s its real purpose. 
 

However, Link support ended 5-6 years ago. You might be better off trying to use CUE 4.33 from the downloads page. I have no idea if the old Link is still viable.

Your coolant hit 40C. On these older GT/VTX models that creates an automatic max fan response. There’s nothing special about 40C unless you are testing it on a bench outside a case. Inside the case in an exhaust position, you’re very likely to get there with extended gpu load and rising case temps. 
 

Cluck the yellow + bar to make a new custom curve. A graph will appear below. Go down to the bottom and change the “sensor” to H80i GT temp (coolant temp). Then in the lower right corner, choose one of those shape tools. Those are the presets.  Choose the quiet one. Now you can see the control points and move them. You also have access to fixed speed which will be an easy way to see if the fan controller is still working. 
 

You can relax the top part of the curve so it does not max out at 40C. However, the better question is should it be at 40C at all?  As these AIOs reach there end of life, most start to loose fluid speed through the unit. The temp slowly gets worse over time. If you cold boot up in the morning in a 20C room and the liquid temp is already 40C, the AIO is dying. With no load coolant temp should be about the same as the internal case temp — usually 4-7C over your room temp with no additional heat factors.
