Hi,

Can someone tell me how to check the RPM of the cabinet fans directly connected to PSU due to shortage of ports on the motherboard ?

Also, is there any way to change to RPM ? they are not PWM ones.

If they are plugged directly into the PSU you can't read the RPM's, but they will be running at max speed. You would need a fan with a dial or switch to adjust fan speeds for fans connected right to the power supply.
Or you could get a fan controller, and plug the fans into that or, into your motherboard.

You can't check the RPM or change the fan speed directly connected to the PSU. Now if you have a laser RPM speed reader you might be able to but you still can't adjust the fan speed. You would have to get a fan speed controller to do that.
