Currently my golden orb has my 700 @ 900Mhz running at 35c idle/39c stressed. Your fan is probably not making good contact with the die. I added Arctic Silver thermal past to lower the temps 3-5c over the old temps. It is important that you remove the motherboard from the case before you install the HSF. Held up to the light you will be able to see if the HSF is sitting flat on the die.
I received two chrome orbs after I wrote the president about the Golden Orb cracking the epoxy from around the die, but it still works. The first one had little feet that fit on each side of the die facing the clips. The second now has the feet removed and the bottom is now square and lays on the rubber feet on the chip itself. I hadn't received the first one when I wrote him again about not receiving it yet, thus may have prompted the shipment of the second. I just received today and I'll be replacing today.
