In the meantime, Maxupgrades released an adaptor for installing the original heatsink-loaded Velociraptor into the HD bays of a Mac Pro
Despite, the small heatsink included in this 48.50 USD adaptor, we are not sure that the HD would not heat more than originally defined by WD, we would need to get such adaptor for a test, as the hottest part of the Velociraptor is located on the controller card side where there is no cooling system. One will need to check it carefully by monitoring the temperature of the Velociraptor thanks to the sensor integrated in it. According to Barefeats, the HD are not getting hotter than when installed in their original heatsink.
For those not willing to invest in such adaptor, we published a month ago a way to install 2 Velociraptor into a Mac Pro without requiring additional kit while maintaining the HD into appropriate thermal working range (here)
