If your Kraken Z series cooler (Z53, Z63, or Z73) is not detected in the CAM software, please check the following guide before continuing:
NZXT Support - My NZXT Device is not Recognized in CAM
If your Kraken Z series cooler is still not detecting, or you are having an issue where the screen is not displaying then this could be either a hardware issue with the Kraken Z cooler or a connection issue.
My Kraken Z cooler shows up in CAM, but the Display is not working
If the Kraken cooler shows up in the CAM software but is not giving a display, this could be an indicator of a hardware issue such as a dead backlight. To test this, first make sure that your Brightness slider in CAM is set to maximum for the Kraken Z cooler.
From here, use a bright light such as the Flashlight function on your mobile phone and point the light at the screen itself. If you see a faint image of what should be on the screen, this is an indicator that the backlight is not being powered. For this, we would recommend the following:
- Shutdown the PC
- Turn off the Power Supply
- Check the Breakout Cable connection at the Kraken's pump cap (see the section below)
- Check the SATA power connection at the Power Supply
- Check the Internal USB 2.0 connection at the pump cap and motherboard
- Restart the PC
If the issue persists, this means that there is likely a hardware issue that is going to require the Kraken be replaced under warranty. If you need assistance placing a warranty claim, please reach out to our Customer Support team and we'll be able to help. Please have your shipping address and proof of purchase for the cooler on hand, as our team will need this to set up the warranty claim.
My Kraken Z's display is blank
If your Kraken Z cooler does not show up in the CAM software and the screen is blank, this may mean that the Kraken is not properly connected or there's a loose connection at the Breakout Cable.
While the Breakout Cable is keyed to help prevent the cable from being improperly inserted, the keying is rather shallow and we have seen incidents of users connecting this cable upside-down into the connector. When connecting the Breakout Cable, you'll notice that one of the 14 pin connections is empty as shown in the image below.
When connecting the Breakout Cable, please make sure that this pin is closest to the Face of the Kraken Z pump cap, away from the Motherboard or closest to the tubes coming from the pump cap.. For example, if you are connecting the Kraken Z with the tube facing the 3 o'clock position, this empty pin should be towards the 3 o'clock position as well.
If the issue persists, this means that there is likely a hardware issue that is going to require the Kraken be replaced under warranty. If you need assistance placing a warranty claim, please reach out to our Customer Support team and we'll be able to help. Please have your shipping address and proof of purchase for the cooler on hand, as our team will need this to set up the warranty claim.
My Kraken Z Display is working and it shows up in CAM, but my system is Overheating
If your Kraken is properly detecting, but the system is showing high temperatures this could be a sign of a pump failure on the Kraken itself. We would note, overheating ranges may vary from CPU to CPU so it is best to first check if your CPU is within safe operating temperatures. If the CPU is designed to hit a higher thermal target or has a higher TDP, you may see higher idle and load temperatures (i.e. Idle of approx. 60C, Load of approx. 95C) than with a lower power processor which may see temperatures as low as the high 20C range at idle and high 80s range at load.
If your system is randomly shutting down however with a CPU temperature warning, then this is a pretty strong indicator of an overheating processor and potentially a pump failure. If you are able to safely load into Windows, open the NZXT CAM software and check the Cooling tab to confirm if the Pump is working by changing the profile to Fixed. All Kraken Z series pumps at 100% work load should give a measurement of 3000 RPM ± 10% (300RPM), meaning a range of 2700 to 3300 RPM on average.
If the Pump is showing 0RPM or a an exceedingly low reading (i.e. under 1500 RPM despite being set to Fixed), this could indicate a hardware issue with the Kraken cooler that'll require the cooler to be replaced. For this issue, we would recommend the following:
- Close the CAM Software
- Close any other Cooling control software
- Re-launch CAM
- Try adjusting the Pump speed manually
- To raise pump speed, drag the left-most point on the curve chart up
- To lower pump speed, drag the right-most point on the curve chart down
- Shutdown the PC and check the Power connections to the Kraken.
If the issue persists, this means that there is likely a hardware issue that is going to require the Kraken be replaced under warranty. If you need assistance placing a warranty claim, please reach out to our Customer Support team and we'll be able to help. Please have your shipping address and proof of purchase for the cooler on hand, as our team will need this to set up the warranty claim.
