The TEC cooler DOES NOT WORK as of 12/31/2020. I received the cooler and installed it last night.
I updated to the latest BIOS from 12/18/2020.
 
The TEC is not picked up by the driver.
 
I thought Intel Cryo Cooling was available on ALL Z490 motherboards?
 
What is going on EVGA?

I am using BIOS version 1.10 released on 12/18/2020.
 
It does not appear in device manager.
 
I can find Ports(COM & LPT) when I show hidden devices, however it does not show the Silicon labs driver.
 
After installing the driver I get the successful install message, I restart PC and nothing.
 
Windows 10 does not pick up the TEC at all.
 
I have unplugged and re plugged the wires of the TEC multiple times to make sure a connection is not loose.
 
I have tried all of my USB headers on my motherboard.
 
I have tried using a USB-A cable instead of the bundled cable.
 
The red LED on the TEC is ON so I know its getting power.
 
 

So, it could be a BIOS setting ... maybe -  stopping the system from seeing the new hardware ?
 
Is Windows Fast startup turned off ?
 
Windows Pro, Home ... other ?  what Version number & OS Build number ?
 
Your logged in as Admin ?
 
Go - offline, stop all background software - Anti-Virus & try to reload the software as Admin

I had reset my BIOS settings to default so fast boot was on.
 
I turned it off and rebooted, but still no dice.
 
 
Windows 10 Pro
Version - 20H2
OS Build - 19042.685
Intel 10900KF
EVGA Z490 FTW WIFI
 
 
I am logged in as Admin. Right click run as administrator on both the Driver install and Intel Cryo Software.

Below is from the manual .. you downloaded Both software packs ?
 
 
After booting the system, you will see that Windows will recognize a new USB device.
 
Please check the device manager to check that you have the following device installed.If the device has a yellow bang (warning) showing that the driver is not installed, please click on Update Driver and Windows 10 will try to retrieve the USB driver and install it
 
If that doesn’t work please install the driver from the following link:•
 
Note: if you don’t see the device in Device Manager please see the troubleshooting section
 
Please download the latest version of the software from the link below and run the installer•
 
Download Intel® Cryo Cooling Technology software

Yes I downloaded both software packs. The Silicon Labs driver will successfully install, however it never picks up the TEC.
 
I can tell the Silicon labs drivers are available by going into Device Manager.
Clicking Action.
Add Legacy Hardware.
Install Hardware manually.
Click Ports(COM & LPT) and click next.
Scroll down the manufacturer list and find Silicon Labs.
Go to Model and choose Silicon Labs CP210x USB to UART Bridge.
 
Now I can manually add the driver and it will appear in hidden devices under Ports(COM & LPT).
 
However it will have the yellow bang next to it and it says.. The software for this device is now installed, but may not work correctly.
The Device cannot start (Code 10).
 
 
Right click on the Silicon labs driver and click update driver and it returns with Windows has determined that this is already the best driver.
 
 
 
Intel Cryo Cooling software - I can't even get this to install without the previous driver working correctly.
Once you hit install it returns an error message to please make sure all cables are connected securely before proceeding with software installation. Please exit installation and try again.
 
 
Also the EKWB manual claims to check the trouble shooting section multiple times... did you notice a trouble shooting section in the manual? Because I couldn't find one.

Cross-post from the other related thread but sharing here for visibility. 
 
I am using the Cryo Cooler with my 490 Dark Kingpin just fine. Per the instruction manual, the only hard requirement of the motherboard for the cooler to work is physical clearance so the block can make a proper seal against it when mounted. The mentioned bios update is just to enable their thermal velocity boost overclocking as there is a cpu microcode update to do so. However if you're not looking to use that feature, then I am unsure what issue would be preventing you from using this. My 10900k at 5.2ghz all core is happily sitting at 19c on all cores thanks to this beautiful piece of tech. :) 

Update:
 
Still no BIOS update.
 
Still no update from EVGA on any progress.
 
Still no compatibility with z490 FTW.
 
Still a DOA product.
 
As the other poster said,  the z490 DARK has had compatibility all along... more expensive board gets the updates? No idea.
 
Unfortunately there is no such luck on my end.
 

Well unfortunately it doesn't work just fine. I've been given the run around from Intel, EKWB and EVGA over this for awhile now.
 
Just to clarify, I work in IT, I am not a technology novice.
 
The driver, CP210x_Universal_Windows_Driver installs fine.
 
I have checked, rechecked and re verified the connections on the TEC countless times.
 
8pin is in and solid. I double checked by replacing a graphics card 8 pin with the TEC 8 pin just to make sure it was getting power.
 
TEC thermal probe is plugged in snugly.
 
TEC power cable is plugged in snugly.
 
USB cable plugged into header produces red LED. / USB cable plugged into USB port also produces red LED.
 
The Intel software will not install. Every time I have tried the installer fails and asks you to re plug in the TEC, as it is not detected.
 
Go into the drivers I can see the CP210x Driver installed but unused.
 
I have gone back and forth with EK for months now. They claim the TEC is operating fine, that it is a software or driver issue.
 
Intel says its a BIOS issue.
 
EVGA says the board is not compatible and they will inform me if it ever becomes compatible, no estimated date.
 
And I have people on these forums saying, no it doesn't need to be supported, it should just work.
 
Well unfortunately it doesn't. I would love to hear from another person using a Z490 FTW motherboard instead of a Z490 DARK to see if it really is my specific TEC or if this motherboard just won't work.
 
Apologize if I come off as rude, this has just been a very frustrating experience.
 

If der8auer can get it working on an AMD cpu, surely we can get it to work on the FTW :) 

Darn.... have you tried reinstalling the USB controller drivers?

He used an Asus board with 10900K to use the software and control it.

I doubt the OP is willing to use a completely separate motherboard just to control the TEC like der8auer.
