What are your full system specs?
This almost certainly has to be a motherboard issue, as that is the only thing common to both the fan headers and the PCI slot that powers the fans for your graphics card. Very unusual to have the CPU and GPU card fans BOTH stop working, and the rest of the system function normally, unless they are turned off in the bios somehow. Pretty sure there is never an option for disabling the GPU card fans though. I'd reset the bios to default settings and see what happens.
Power off the unit, switch the PSU off and unplug the PSU cord from either the wall or the power supply.
Remove the motherboard CMOS battery for five minutes. During that five minutes, press the power button for 30 seconds. After the five minutes is up, reinstall the CMOS battery making sure to insert it with the correct side up just as it came out.
Now, plug the power supply cable back in, switch the PSU back on and power up the system. It should display the POST screen and the options to enter CMOS/BIOS setup. Enter the bios setup program and reconfigure the boot settings for either the Windows boot manager or for legacy systems, the drive your OS is installed on if necessary.
Save settings and exit. If the system will POST and boot then you can move forward from there including going back into the bios and configuring any other custom settings you may need to configure such as Memory XMP profile settings, custom fan profile settings or other specific settings you may have previously had configured that were wiped out by resetting the CMOS.
If the system will not POST after resetting the CMOS, then there is a hardware problem of some kind.
