Several weeks ago, I ordered the Golden Orb for Socket A from a vendor whom I have used for years. Two days after I received the HSF, the vendor posted at his web site that this Golden Orb is defective and should not be used. When I returned the unit for refund, I was shocked to find that, not only I have to pay the return postage, the shipping cost was deducted from the refund too. I was out of $7+ when the vendor and his manufacturer messed up. I emailed the vendor to ask him to post clear policy statement on return of defective products, but have not heard back from him.
Find a vendor with a clear return statement before you order the Chrome Orb. It was designed for the Socket A and may not work with the FC-PGA.
