Teardown: Cooler Max Liquid Cooling System

October 17, 2022 by Tom Nardi 57 Comments

Every week, the Hackaday tip line is bombarded with offers from manufacturers who want to send us their latest and greatest device to review. The vast majority of these are ignored, simply because they don’t make sense for the sort of content we run here. For example, there’s a company out there that seems Hell-bent on sending us a folding electronic guitar for some reason.

At first, that’s what happened when CoolingStyle recently reached out to us about their Cooler Max. The email claimed it was the “World’s First AC Cooler System For Gaming Desktop”, which featured a “powerful compressor which can bring great cooling performance”, and was capable of automatically bringing your computer’s temperature down to as low as 10℃ (50°F). The single promotional shot in the email showed a rather chunky box hooked up to a gaming rig with a pair of flexible hoses, but no technical information was provided. We passed the email around the (virtual) water cooler a bit, and the consensus was that the fancy box probably contained little more than a pair of Peltier cooling modules and some RGB LEDs.

The story very nearly ended there, but there was something about the email that I couldn’t shake. If it was just using Peltier modules, then why was the box so large? What about that “powerful compressor” they mentioned? Could they be playing some cute word games, and were actually talking about a centrifugal fan? Maybe…

It bothered me enough that after a few days I got back to CoolingStyle and said we’d accept a unit to look at. I figured no matter what ended up being inside the box, it would make for an interesting story. Plus it would give me an excuse to put together another entry for my Teardowns column, a once regular feature which sadly has been neglected since I took on the title of Managing Editor.

There was only one problem…I’m no PC gamer. Once in a while I’ll boot up Kerbal Space Program, but even then, my rockets are getting rendered on integrated video. I don’t even know anyone with a gaming computer powerful enough to bolt an air conditioner to the side of the thing. But I’ve got plenty of experience pulling weird stuff apart to figure out how it works, so let’s start with that.

Custom Electronic Load Makes Use Of Gaming PC Tech

October 18, 2020 by Tom Nardi 14 Comments

At first glance, you might think the piece of hardware pictured here is a modern gaming computer. It’s got water cooling, RGB LED lighting, and an ATX power supply, all of which happen to be mounted inside a flashy computer case complete with a clear window. In truth, it’s hard to see it as anything but a gaming PC.

In actuality, it’s an incredible custom electronic load that [EE for Everyone] has been developing over the last four months that’s been specifically designed to take advantage of all the cheap hardware out there intended for high-performance computers. After all, why scratch build a water cooling system or enclosure when there’s such a wide array of ready-made ones available online?

The “motherboard” with single load module installed.

Inside that fancy case is a large PCB taking the place of the original motherboard, to which four electronic load modules slot into. Each of these loads is designed to accept a standard Intel CPU cooler, be it the traditional heatsink and fan, or a water block for liquid cooling. With the current system installed [EE for Everyone] can push the individual modules up to 275 watts before the temperatures rise to unacceptable levels, though he’s hoping to push that a little higher with some future tweaks.

So what’s the end game here? Are we all expected to have a massive RGB-lit electronic load hidden under the bench? Not exactly. All of this has been part of an effort to design a highly accurate electronic load for the hobbyist which [EE for Everyone] refers to as the “Community Edition” of the project. Those smaller loads will be derived from the individual modules being used in this larger testing rig.

We’ve actually seen DIY liquid cooled electronic loads in the past, though this one certainly sets the bar quite a bit higher. For those with more meager requirements, you might consider flashing a cheap imported electronic load with an open source firmware to wring out some extra functionality.

Original Xbox Gets The Steam Overhaul

June 2, 2020 by Tom Nardi 28 Comments

When Microsoft released the original Xbox, it deviated from the design of traditional game consoles in that it used several off-the-shelf computer components. The fact that Microsoft would want their game console to resemble a PC isn’t particularly surprising in hindsight, but we doubt anyone at Redmond ever imagined folks like [Ryan Walmsley] would be cramming in full-fledged computers nearly 20 years later.

[Ryan] tells us he was looking for a way to play some older games from the early 2000s, and thought it was a good opportunity to put together a quiet set-top computer. The final hardware is more than capable of running older titles, and can even be used with Steam Link to stream newer content from his primary gaming computer.

Even with a diminutive Gigabyte GA-H81N Mini ITX motherboard, things are pretty tight inside the Xbox. Fairly tight wire management was required to prevent any airflow obstructions, especially since [Ryan] decided to put the system’s 80 watt laptop-style power supply inside the case. While this made the build a bit more complicated, it does make the final product a lot cleaner and makes it feel just that much more like a proper game console.

Benchmarks show the machine has decent performance, all things considered. [Ryan] says there are some potential upgrades down the line, but as with most gaming PC builds, cost is the limiting factor. Until he’s ready to spend the cash on revamping the internals, he says that streaming newer games over the the network has been working great.

For those looking for a slightly more modern alternative to this project, we’ve also seen a gaming PC shoehorned into an Xbox 360 with similarly impressive results.

A Water Cooled Gaming PC You Can Take With You

January 17, 2020 by Tom Nardi 39 Comments

Have you ever been stuck in a hotel room wishing you brought your VR-capable gaming PC along with you? Well [thegarbz] certainly has, which was the inspiration for this absolutely gorgeous mobile rig affectionately known as “The Nuclear Football” that brings console-level portability to those who count themselves among the PC Master Race.

OK, fine. We’ll admit that the existence of gaming laptops means you don’t actually need to carry around such an elaborate contraption just to play Steam games on the go. But if you’re going to do it, shouldn’t you do it in style? More practically speaking, [thegarbz] says the cost of this project was less than what a gaming laptop of similar specs would have cost.

The Nuclear Football features a Ryzen 5 2600 processor, a NVIDIA 2070 Super graphics card, and 16 GB of DDR4 RAM. The water cooling gear is from Alphacool, and includes a custom controller that links to the computer and allows [thegarbz] to monitor temperatures and fan speeds via a widget on the desktop.

While not nearly as mobile, this machine does remind us of the water cooled “Big O” that packed all the current-gen consoles and a gaming PC into one glorious machine.

Ask Hackaday: Are Gaming PCs Hard To Build?

September 17, 2016 by Will Sweatman 170 Comments

No. No they’re not. But let’s talk about it anyway.

The endless trenches of digital worlds are filled with hardcore gamers from all walks of life. They can be found exploring post-apocalyptic Boston in Fallout 4, and commanding Sgt. Recker through a war-torn landscape in Battlefield 4 for hours on end. Their portal into these vast digital worlds come via some sort of computer system.

What type of computer system used is a point of contention between many gamers, and is typically divided between console versus PC. I will not dare to drag you into the captious arguments between the two, but instead we will focus on something that has something in common with our world — how does a previously non-technical console enthusiast cross over and build a gaming PC?

Many hackers have built computers from scratch and [Adam Fabio] just covered a bunch of custom laptop builds this morning. People with such skills can easily build a high-end gaming PC. But what about people without such skills? Can a console gamer with no technical background build a high-end PC gaming system?

Inspiration for this article came after reading something [Emanuel Maiberg] published over the summer on Motherboard. Why someone writing for a publication called Motherboard would have trouble building a gaming rig is beyond me. Certainly I think his starting assumptions are questionable. He asserts that you need an unreasonable amount of time and money to attempt one of these projects. But gaming rigs can be purchased fully-assembled — those that build them are doing it out of passion.

The question is this: How far should engineers go to make a technical product easier to use for a non-technical person? If I order an engine for a hot rod, it can be assumed that I know to hook up the gas line without specifically being told to do so. After all, a person who’s going to put an engine in a hot rod probably knows a thing or two about engines.

I think that building a desktop PC has never been easier. We’ve now had 30 years of evolution to help weed out the “slow learners” when it comes to manufacturers. The Internet is a lot easier to use for answers than it used to be, and we have faster means of connecting with communities of experts than ever before.

That said, the neighborhood computer store is beginning to go the way of the dodo. There is an entire generation of “mobile-first” users who will give you a blank stare if you start talking about “desktop computing”. And familiarity with the fact that computer customization is even possible is beginning to fade; if all you’ve ever used are tablets and smartphones “upgrade” and “customization” are software terms, not hardware possibilities.

So we turn it over to you. Are gaming PCs hard to build? Have engineering practices and design choices made it easier than it used to be to get into it? What do you think is happening with the average skill level for working with computers now compared to when you had to open the case to add a modem to your machine?

Lego Gaming Computer Case

February 11, 2016 by Richard Baguley 37 Comments

Lego isn’t the first material that springs to mind when you think about building a new gaming computer case, but it does make sense when you think about it. It is easy to work with, can be easily reconfigured, and it’s pretty cheap. That’s the idea behind this very cool (no pun intended) gaming computer case build by [Mike Schropp]. Built around a Skylake i7 CPU and an NVidia 980 Ti graphics card, his build has an unusual X-shaped design that allows for plenty of airflow. The sides of the X hold the CPU cooler, the power supply, the hard drives and the graphics card cooler, so each of them has its own separate flow of cool air from the outside. That avoids the common problem of hot air from one component being passed over another, so it doesn’t get cooled properly. Critically for a gaming system, this design keeps all of the components much cooler than a more traditional case, which makes for more overclocking potential.

At the moment, [Mike] says he is struggling to keep up with the demand for people who want to buy custom versions of his build, but he is planning to release the details soon. “Initially that will probably be in the form of a DIY kit, where you can buy the plans with all the Lego bricks needed for the build, in a kit form” he told us. “Then you can add your own computer components to complete your build. At some point I’ll probably also just offer the plans themselves and allow the end-user to acquire the Lego bricks needed.”

Build An Amazon EC2 Gaming Rig

July 10, 2015 by Brian Benchoff 44 Comments

PC gaming is better than console gaming. Now that we’ve said something controversial enough to meet the comment quota for this post, let’s dig into [Larry]’s Amazon EC2 gaming rig.

A while ago, [Larry] bought a MacBook Air. It’s a great machine for what it is, but it’s not exactly the laptop you want for playing modern AAA games on the go. If you have enough bandwidth and a low enough ping, you can replicated just about everything as an EC2 instance.

[Larry] is using a Windows Server 2012 AMI with a single NVIDIA GRID K520 GPU in his instance. After getting all the security, firewall, and other basic stuff configured, it’s just a matter of installing a specific driver for an NVIDIA Titan. With Steam installed and in-home streaming properly configured it’s time to game.

The performance [Larry] is getting out of this setup is pretty impressive. It’s 60fps, but because he’s streaming all his games to a MacBook Air, he’ll never get 1080p.

If you’re wondering how much this costs, it’s actually not too bad. The first version of [Larry]’s cloud-based gaming system was about $0.54 per hour. For the price of a $1000 battle station, that’s about 1900 hours of gaming, and for the price of a $400 potato, that’s 740 hours of gaming.
