this is the hr2 it is big and heavy and
it is made by thermal right they are advertising this as a fanless CPU Cooler
so they're saying that you can actually run many of today's modern high
performance CPUs fanless completely
passive as long as you have some case air flow with this particular heat sink
so let's take a look at it the first thing we find is a thermal rate sticker
then we have an installation guide which shows us a view of how to to uh attach
all of the different mounting brackets it does include mounting for uh 775
1366 1156 as well as am2 as I recall uh
let me just uh we'll double check that when we get to the actual Hardware okay
so here's the included mounting hardware you can see this is clearly for am2 and
then this is clearly a multi- installation kit for Intel all right
let's see what we got for look at this it comes with a screwdriver check that
out Chrome vadium okay I don't actually
know how to pronounce that vadium vadium neat it's a screwdriver magnetic
hey it's magnetic too look at that do we have anything to test it on around here
okay here here yeah yeah here's a PCI back
plate it's not very magnetic okay well
that's okay you still get a free screwdriver with your heat sink purchase
that is a compelling bundle
offering okay mounting hardware I'm going to need my handy dandy Tech tips
knife which I now actually have there we
go that is officially open now so in
here we will find a variety of things we've got some rubber grommets we have
some fan Clips we have some thermal compound
cf3 next we have a wrench you got a wrench and a screwdriver you get like a
tool kit with this thing and then we have the am2 mounting hardware also am3
and then we have the uh multi back for Intel so uh here yeah 775 1156 and
1366 all right let's look at the heat sink itself since that's the most
interesting part of this video other than me of
course no I'm kidding I know the heat sink's the most interesting part so this
is the H2 and it has a couple of unique Design
Elements so we'll get started here once I finally have it out of the
bag that thing is H huge so first of all
it has a boatload of heat pipes you can see it's actually got six full u-shaped
heat pipes so that's almost 12 effective
heat pipes when you look at how they're all attached to the base it's a very
very shiny flatl looking base and we'll do the obligatory finger shot that
everyone in their dog seems to be determined to complain about but I don't
really care all right so you can see
first of all that this heat sink has a very very wide spacing for the fins
that's because it does rely on passive cooling so that means when this is
installed on your socket okay so let's say hypothetically it's installed like
this it relies on the heat that is
generated by the heat pipes transferring heat to the fins to Simply heat the air
and then the air will rise out of it or be pulled Slowly by a case fan and
that's it that's the only Force you have so that's why the fins need to be spaced
really wide so that it doesn't take a lot of pressure to push the air through
it now besides the wide spacing of the fins you can see what thermal R's done
is they've actually used their little um I don't know if they actually even have
a name for this but what they've done is they've cut little holes and bent up the flaps in every one of the aluminum
layers here and that gives us just a little bit more surface area so based on
that so you can see that's all the way through the heat sink I would probably
recommend mounting this heat sink this way either this way or this way because
that's going to mean that I mean heat rises so it means that you're giving the
air less resistance to rise up through the heat sink and cool your CPU now this
hole right here is probably why you need the screwdriver that's how you're going
to uh screw it in if you're using an
am2 uh socket so that's positioned right
there for that and then on the other side you can reach it quite a bit more
easily that's one of the considerations when you're building a heat sink this
big is how do you actually access the mounting hardware and uh so people can
actually attach it to their motherboard cameraman's giving me his iPhone for the
usual scale shot so you can see compared to an iPhone it would crash
it it's quite a bit bigger and heavier
okay so there it is from the side and let's just have a closer look at how
they've attached the uh the heat pipes down here at the bottom so it's six heat
pipes alternating so some of them go over to this side of the heat sink and
the others just go straight up in a straight U shape so all six of them are
aligned at the same level I've actually seen some coolers where some of the heat
pipes are a little bit higher and I don't know what that would do in terms
of thermal transfer but this way they're all as close as possible to the CPU
without touching directly and I think that pretty much covers everything I
wanted to say about the hr2 I'm actually kind of curious to try this one out and
see uh see how well it can do on even like a a core i7 or something like that
it's very heavy though
