My cooler isn't working. How do I fix it?
If your cooler isn't working, first check if your cooler has a SATA power connector.
If your cooler has a SATA power connector:
Make sure your cooler is directly connected to the power supply unit’s SATA connector. Do not use any type of adapter (Molex-to-SATA) for power; many adapters cannot withstand heat for a significant amount of time, and it may constitute a fire hazard.
You can also try a different SATA connector on the PSU, preferably one that doesn’t have any other devices connected to it.
If your cooler only has a 3-pin header and no SATA connector:
Check your BIOS settings to see if they are running the cooler at its optimum settings.
For example, ASUS motherboards will have a setting called QFanControl. This setting is used to lower fan speed on certain headers to make them quieter. On a Hydro Cooler, this can make the unit unable to circulate liquid.
Regardless of the name of the setting, make sure the header that the cooler is connected to is set to the maximum or fastest setting possible.
My AIO is powering on, so why is my unit still overheating?
If your unit is still overheating, make sure your fans and radiator are clean of any dirt or debris.
If you’ve had your unit for some time, try reapplying thermal paste.
If your cooler has a 3-pin header and no SATA connector, check your BIOS settings and make sure the header that your cooler is connected to is set to the maximum or fastest setting possible.
If your cooler still isn’t working, contact our support team. We do NOT recommend opening or modifying the cooler in any way, because doing so will void the warranty.
How often should I replace my thermal paste?
It’s best to reapply thermal paste every 12 to 18 months.
What do I do if my cooler backplate feels loose?
It’s common for the backplate to feel loose after you install it for the first time. Once the pump has been seated and tightened down, it will pull the backplate to the motherboard.
What do I do if it sounds like there is some air in the loop?
It’s possible that air was trapped within the tubes during production, causing air bubbles to appear in the pump. If you notice air bubbles in the pump, try running the system continuously for a few hours to allow the pump to work out the air bubbles.
What do I do if my cooler leaks?
If your cooler leaks and is still within warranty, please contact our support team immediately at https://help.corsair.com.
