New AMD Retail 'sinks?
When did AMD switch retail HSF designs? I just bought 2 2500s, and the heatsink they've got is different from the one that came with my 1700+ Palomino... it's almost exactly the same size, but the fan is a bit thicker, it's quieter (the fan is a 18cfm/28dba delta 60x13mm) than the older one, and it's a hell of a lot heavier- probably 2x as heavy. What that indicates to me is a copper base, but the base is silver. So maybe it was silver plated, but the surface looks more like aluminum to me... I'm going to sand/file down the side of one of them once I know the cpu is good to see if it is copper... it also has a 3-prong clip (which is insanely stiff, btw...) and the thermal pad is silver instead of pink...
Normally I don't use the retail hsfs, but I didn't feel like assembling one of my SLK-800s at the time, so I just threw the retail hsf on it...
for those of u that have no idea what I'm talking about, I took some pix...

Those are actually the Antec design reference (as I had a Antec HSF just like it)
Try to ship something that heavy, and a single clip hsf makes a nice mess. Invision that thing rattling around inside a case being thrown by a UPS carrier. Sorry sir, how many clips with your order today??
Looks like a nice heatsink. Maybe my next 2 2500+ will be retail.
muddocktor- it MUST be copper... either that or steel or tungsten 'cause that heatsink is H-E-A-V-Y for such a little guy...
I typed the above ^ about 10 minutes ago... then I went downstairs and grabbed my dad's digital balance to see just how heavy these things are... I also measured them with my dad's digital calipers...

Notes:<ul>
<li>The stock heatsinks were measured with the shrouds in place
<li>The CAK-38 was weighed with the stock AMD clip because the Globalwin one broke
<li>The Gladiator was measured without the shroud because it was damaged
<li>Length is the clip side, Width is the other side, Height is the thickness from the base to the top of the fins/shroud.
<li>The SLK-800A was measured from the base to the top of the lowest fins, and at the maximum Length & Width
<li>The protective film on the SLK-800A was left in place
<li>While the balance and calipers read to 2 decimal places, manufacturing variances make the last 2 places irrelevant.
</ul>
So the new stock heatsink weighs a good bit more than the old one does, even though it's almost exactly the same size.
Model # DC1206BM-PCu-M
BTW heres a Opteron Heatsink by Dynatron
They run at around 5400-5600RPM's
