 This is the HR-02. It is big and heavy and it is made by Thermalright. 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 airflow with this particular heatsink. So let's take a look at it. The first thing we find is a Thermalright sticker. Then we have an installation guide, which shows us a view of how to attach all of the different mounting brackets. It does include mounting for 775, 1366, 1156, as well as AM2, as I recall. Let me just... 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. Alright, let's see what we got first. Look at this! It comes with a screwdriver. Check that out. Chrome Vanadium. Okay, I don't actually know how to pronounce that. Vanadium? Vanadium? 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 the PCI backplate. 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 gonna 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've 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 multi-backplate for Intel. So, yeah, 775, 1156, and 1366. Alright, let's look at the heat sink itself, since that's the most interesting part of this video. Other than me, of course. Nah, I'm kidding. I know the heat sink's the most interesting part. So this is the HRO2. 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 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, flat-looking base. And we'll do the obligatory finger shot that everyone and their dog seems to be determined to complain about. But I don't really care. Alright. 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 Thermalright's done. Is they've actually used their little, 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 screw it in if you're using an AM2 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 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. Ah. 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 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 HRO2. I'm actually kind of curious to try this one out and see how well it can do on even like a Core i7 or something like that. It's very heavy though.
