 When we first heard about CompuLab back in 2017, they claimed something we thought was impossible. Cooling an i7-7700K and a GTX 1060 completely passively, like no fans at all, and in a shockingly small case. But then we tested it and yeah, they actually did it. But even with that track record, and the fact that I personally use the AirTOP 2 as my workstation at home, even I was skeptical when CompuLab told us that the new AirTOP 3 could cool a freaking 8-core Intel Core i9-9900K, and an Nvidia Quadro RTX 4000 again, completely passively. So let's see if Lightning can strike twice, because if so, we might be looking at my new favorite PC on the market. But not until my new favorite sponsor Segway. A Ridge Wallet is a sleek way to keep wallet bulge down thanks to its compact frame and RFID blocking inner plates.

Like the 72 pound Calio Spandless PC or the more recent Monster Labo the first. But the AirTOP 3 is a surprisingly compact machine, smaller than similarly powerful small form factor desktops like the MSI Trident X and the Corsair One. Enough foreplay though, let's plug in the dual power bricks and see if CompuLab actually has tamed this i9-9900K using nothing but convection. When cranking out an all-core Blender render at first, it turbos to about 4.6GHz before stabilizing around 3.7. This is slightly higher than Intel's official spec for this chip with temperatures leveling out at an extremely decent 80 degrees. For context, that's similar performance to the Corsair One Pro, a machine that's water-cooled and has fans. But the AirTOP isn't just a CPU, you also get an Nvidia Quadro RTX 4000, 32GB of RAM, and a 1TB Samsung 970 EVO for storage. Which is actually very similar to the specs of my work desktop, so that makes me wonder, could the AirTOP be faster? Like sure, it has newer parts, but my desktop is overclocked and has a massive Noctua NHD 15 and like, it's just so much bigger. You'd think it would just mince a computer this small that doesn't have a fan. But in every single test, the AirTOP 3 came out on top, sometimes barely, but generally it just absolutely creamed my workstation with the RTX 4000 really showing its muscle. And if you're into gaming, the RTX 4000 features the same core as the RTX 2070, although with slightly lower power and boost clocks. And it cranks out heaps of frames at 1080p and even keeping up at 4K. The only downside though is that when the GPU stretches its legs, the coil whine can be audible. Something I don't remember from the 1060 model, but since it's behind a thick piece of aluminum, you really can't hear it for more than about a foot away. So how the heck have CompuLab been able to cool all of this, using these rather unassuming channels along the outside of the case? Well, hot air rises, so the aluminum channels on the side heat up, and then air naturally flows past these fins. This creates a surprising amount of airflow as demonstrated by this tear-free pinwheel. But for the convection to happen efficiently, the heat first has to be moved away from the CPU and spread evenly across the side panel. To do this, CompuLab has put a heat pipe on a bigger heat pipe that's on two more absolutely huge heat pipes that go along almost the entire area of the side panel. Now this does mean the sides can get pretty hot, not hot enough to burn you, but like, I wouldn't hold my hand against it for an extended period of time. Hey Riley, do you know where... Uh, what are you doing buddy? I'm just holding my hands on my computer for an extended period of time. Right on! What? What is normal? People do it! People, people do it. Another benefit is dust. Since although airflow is created, it doesn't have the dust sucking strength of an intake fan. In the time since I got my Airtop 2 at home, I haven't even thought about dusting it. Meanwhile, I've cleaned out the dust filters on my main PC twice. These heat sinks also give it a very premium look and feel, like seriously, this is probably the solidest desktop that I've ever held in my hands. You don't get the RGB frills that you might on say a Corsair 1, but you do get this mini OLED screen that shows vital stats like CPU, GPU, and storage temps, along with system power and networking info. As for front I.O., you get two USB 3 Type As, a USB-C, headphone and microphone, but around back is where it really gets interesting. Yes, there's an additional six USB Type As, but there's also three serial COM ports, redundant ethernet, as well as digital and analog audio. There's also support for up to seven displays, four that are off the dedicated GPU and three off the integrated. You might expect upgradeability in a case this small and specialized to be quite a challenge, but it's actually stupid easy. All you need to do is just unlock it on the back, click there, and then press the top and wow, there we have the GPU, the storage, and the RAM. That's really about all you need. Upgrading the storage just requires pulling this yellow lever and four two and a half inch bays pop out with two NVMe M.2 slots underneath. One small but welcome improvement is this new flattened PCIe power cord. On my old Airtop 2, the cord folded weird and broke, requiring a bit of soldering to fix, but now this is just a non-issue. As for upgrading the GPU, if you're an advanced user, it might be possible to swap it out while keeping the original side panel. They do use the stock GPU mounting holes, but CompuLab also offers a complete side panel upgrade that comes with a new GPU installed. This also means if you don't need the GPU grunt, you can swap out the side for dual 10 gig ethernet or additional storage. This one has three very well-cooled Samsung 970 EVOs and RAID 0 for some truly staggering read numbers. So what's the catch? The Airtop 3 is almost completely silent, super powerful, stays surprisingly cool, and is easy to upgrade. Well, the catch is that our model is over $3,500 US dollars. If you're looking for a gaming machine, look elsewhere. The Quadro GPU alone contributes $1,200 to that total. But if you're an engineer or a scientist and need a machine that has the power to back up your work, the CompuLab Airtop 3 is an awesome option. And when we set up our new workshop in the coming months, I know what will be powering it. Massdrop collaborated with Sennheiser to create the PC37X gaming headset. It's got an open back design with the drivers from the HD series, the 598, 600s, those guys. And it features clear audio for gaming and music. The mic is optimized to avoid unpleasant pops and hisses. It's also noise canceling. And the mic automatically mutes simply by rotating it up until you hear the click. It includes a 10 foot braided cable and you can buy it today and get $20 off at the link in the video description. Go check it out. So thanks for watching guys. If this video sucked, you know what to do. But if it was awesome, get subscribed, hit that like button, or check out the link to where to buy the stuff we featured in the video description.
