Can I install a Xigmatek Aegir SD128264 heatsink on an AM3+ socket CPU

Several months ago, I bought the Aegir SD128264 heatsink I wanted to install on an AMD Phenom II X6 1100T CPU which uses an AM3 socket but never did it.

Now, I changed my mind and want to buy a new faster CPU which is the AMD FX-8150 Eight-Core which uses an AM3+ socket.

The Aegir spec says that SD128264 supports "AM2/AM2+/AM3" but AM3+ is not mentionned (http://www.xigmatek.com/product.php?productid=99&type=feature)

Are AM3 and AM3+ sockets coolers' compatible so I can install my SD128264 on the AMD FX-8150 ?

Thanks in advance for confirming (or not).

There's a fifth of an inch difference between the socket sizes, even
though the pin count is incremented only by one from 941 to 942.
Fairly large sounding in terms of tight squeezes. However, according
to AMD, they haven't changed the HS retaining bracket sizing. Might
take care to verify that bit of volunteered information, either and as
well through others and their experience, or directly from AMD so to
verify the claim source. May be a bit dicey for hit and miss, as AMD
is playing it tight fisted by retaining information on the newest
specifications as proprietary.

The Wikipedia article is wrong.

http://en.wikipedia.org/wiki/AM3+#Socket_AM3.2B

The ZIF socket has holes drilled in it. The diameter of the holes
is 0.51mm instead of the previous 0.45mm. The Wikipedia article
mis-copied that information and references 51mm versus 45mm. It's
just the drill diameter used to drill out the plastic of the socket.
(The implication, is the ZIF contact design is different, but there
are no pictures of the details.)

In the bottom picture here, the retention bracket is different.

The new retention bracket, would bolt to a plate underneath the motherboard.
The tabs look to be in the same location as before.

But the Aegir SD128264 doesn't use the tab at all, in any case.

You unbolt the retention bracket, and use the holes in the motherboard,
to take the new backing plate that comes with the Aegir.

A Newegg reviewer for Aegir SD128264, warns to check where the back
plate meets the bypass capacitors on the solder side of the motherboard.
The person installing it, notes that there is a potential if the backing
plate bends a bit, it may touch a capacitor on the backside. So when
installing the thing, it may help to physically check that the plate
isn't going to crush or short anything.

Since that is a bolt-on heatsink, it requires removing the
motherboard to install it.

Right. That whole thing wasn't making a hell of a lot of sense, but
then with the hardware sites trying to figure out pin assignments,
subtleties in differences - no help from AMD - all I gathered was an
AM3 processor and heatsink is just fine with an AM3+. Or close enough
for horseshoes, hand grenades and hearsay. Yes, I've got some of that
stuff for totally removing the standard surrounding MB processor cowl,
and, imo doing it right with metal for a backplate to bolt the
heatwick's base. With experience and a feel for it, of course. I can
also see someone taking the bolts and cranking down until its one
smashed mess of a sandwich between. Got one, a spare in a box
intended for my AMD dual core, matter of fact -- have to tear the
whole thing down, but it'll be super quiet when I do get around to
it. Problem is to be careful with some strong magnifiers, common
sense stop-fixes if necessary - there's teflon coatings on those
mountings brackets and whatnot involved in protecting the MB, which
with only a little usage, I see showing signs of wearing off, leading
to potential shorts across exposed signal/current traces.

Thanks for your help.
So I will check for the capacitor on the back when I buy my new AM3+ motherboard.
Anyway, the Aegir plate has a kind of soft rubber which should prevent from damaging the motherboard when I bolt the heatsink.
Anyway, I will also try to directly ask Xigmatek and see if they reply to me.
