OMG why such huge heatsinks.. Passive 4670s have been done before with heatsinks half the size??!!

I love the fact that the 4670 heatsink has a PCI-type connector - presumably to prevent excessive stress on the screws holding it to the card!

As far as heatsink sizes go, I don't think we've seen a passive 4670 before, have we? I know Sapphire did a 4650, but they fairly significantly down-clocked it to passively cool it. This is a full fat 1GB 4670 running at full tilt - I'm not surprised it needs a hefty heatsink!

What's so "green" about a passive cooler?

Less electricity ;) them thar fans are so very wasteful y'know.

Anyway... at least the cooler is on the correct side of the card - i hate passive coolers with reach-around heatpipes as they're basically no-go on some motherboards/cpu heatsink combos.

Clearly that's the Royal "we" as the rest of us mere mortals HAVE seen at least one for sale for a year or so - I think there is another 4670 as well.

Good call - I could've sworn that the Ultimate was a 4650! :embarrassed:

That said, if you took the fins and structure that wraps round the ultimate and put it all on one side you'd probably find it's about the same size as the PowerColor HSF - just distributed differently....
