The actual mounting and testing has been arranged in our test lab that the mounting bracket supplied with Ninja PLUS Rev. B CPU Cooler does fit without interfering or touching the components as shown in the below image.

Disclaimer:
Please note that this compatibility may not apply to all the motherboards as the manufacturer randomly tend to change the components (capacitors, condensers, etc) used for their motherboard without informing to the public. Hence, the height of the capacitors and condensers maybe higher depending on the production lot of the motherboard.
We are not sure if there are different versions of this board out there but it will install and we are currently testing performance levels on the Asus P5B Deluxe.

1. Screws to mount the mounting bracket onto the heatsink
Please make sure to securely tighten the 4 screws (shown in the below image with red arrows) in order to have a firm attachment of the mounting bracket to the heatsink base
