be quiet! Dark Rock Slim CPU Cooler Review: The Strong, Silent Type

The Dark Rock series from be quiet! had to this point been on the larger side of CPU air cooler designs, but not everyone wants (or can even use) a large heatsink. And while be quiet! already has a lower-profile version in the Dark Rock TF, with the Dark Rock Slim the German company adds a slim, single-tower design to the family. First revealed at CES 2019, the be quiet! Dark Rock Slim was officially launched in May, offering a premium take on the narrow single tower design of coolers like the ubiquitous Cooler Master Hyper 212 EVO, and boasting a cooling potential of up to 180W. So how does the Dark Rock Slim perform? And how does that Hyper 212 EVO fit into all of this? Let’s get started! “The Dark Rock Slim offers an exceptionally high cooling performance of 180W TDP and virtually inaudible operation. Perfect for high-end builds with limited space.” The Dark Rock Slim arrives in the customarily well-protected packaging of a be quiet! product, and inside the box the heatsink and fan are encased separately in foam, with a box of installation hardware for both Intel and AMD systems. We’ll look first at the heatsink, which measures 47.4 mm thick, 127 mm wide, and 159.4 mm tall. ...

Machine reliability can lower costs, increase profitability. Here’s how

The happiest workers on any plant floor are those who do not have to worry about machine failures that bring production to a halt, eat into productive man hours, and add to production costs. The key to a smoothly running plant floor are machines    that run like clockwork and do not break down frequently. How can we ensure such machine reliability in an age of uncertainties? Machine reliability is a measure of the odds that an equipment will perform at its optimal level during its lifetime without the threat of breaking down at regular intervals. When equipment operates at duty capacity for as long as expected, it is considered reliable. When the period between out-of-service episodes is too short, it is considered unreliable. Measuring machine reliability is important if you want to improve it. Reliability is measured as the average time between failures, better known as ‘Mean Time Between Failure’ (MTBF). One drawback with only measuring time is that there is no indication of the value of that level of reliability. If you do not know what reliability is worth, you may spend lots of money on small improvements that have little impact on profitability. Or worse still, not spend ...

So it’s come to this: BILLY is joining the gig economy, and he’ll hold your books

So it’s come to this: BILLY is joining the gig economy, and he’ll hold your books and whatever else you see fit until you upgrade to KALLAX or HEMNES, or you finally bring yourself to KonMari all your worldly possessions away. IKEA recently announced that it is looking to launch a subscription model, in which customers effectively “lease” furniture and trade it back via credit system; depending on the condition, the Swedish behemoth will either refurbish or recycle the used items. Initially limited to the office market, the scheme conjures dainty visions of a low-rent WeWork, all LINNMON tabletops and ADILS legs, and maybe some TRÅDFRI smart lightbulbs for good measure. If all goes well in Switzerland, where IKEA is reportedly piloting the service starting this month, you’ll soon be able to rent your kitchen — in Northern Europe, cabinets and appliances are regarded as movable furniture, which the occupant buys and takes with them — and maybe even your next NORDLI. At first blush, it sounds like another case of the subscription model taking finer slices — or in IKEA’s case, an EKTORP-sized chunk — of modern life, from the latest Drake album and The Great British Baking Sho...

An Engineer’s Guide to Laser Cutting > ENGINEERING.com

1967 had the Summer of Love, Thurgood Marshall’s confirmation to the Supreme Court and—if you’re a hockey fan—it was the last time the Toronto Maple Leafs won the Stanley Cup. There was also no shortage of engineering news in 1967, including the Apollo 1 disaster, the Saturn V rocket’s first launch and the Concorde’s debut. Here’s another event from 1967 that was arguably just as important but didn’t get nearly as much press: Peter Houldcroft, then Deputy Scientific Director at The Welding Institute in Cambridge, UK began his experiments using an oxygen assist gas to cut a 1mm-thick steel sheet with a 300W CO2 laser. This marked the beginning of using lasers for industrial material processing. Now, 50 years later, laser cutting machines account for the largest segment of the metal cutting machine market, which also includes plasma, waterjet and mechanical cutting. In the simplest terms, a CNC laser cutter uses a coherent beam of light to cut material, most often sheet metal, but also wood, diamond, glass, plastics and silicon. Broadly speaking, laser cutting can be divided into two types: laser fusion cutting and ablative laser cutting. Laser fusion cutting involves melting mate...

Many have tried building a free energy-producing magnetic motor. I am seeing a lot  in my daily quest through alternative energy news, but what I have learned is that energy is not free, perpetual motion machines do not exist, everything is taken from somewhere and put elsewhere. There also is this so-called “free energy”, the zero-point energy, proven mathematically by many scientists. My duty as a green optimistic is to collect everything I see someone has struggled explaining and demonstrating, put it in one place and let the people see and comment. Such is the example of this magnetic motor. But there are also “green pessimistic” websites. When they see something out of “common sense” boundaries, they freak out and scream something like”omg, this can’t be real! I need no proof! I must not think of this! Perish, Satan!” I took such an article today as an inspiration because it talks about a magnetic motor, one of my favorite free energy topics, about which I haven’t heard much lately. Here is the whole process of transforming the free magnetic energy into mechanical energy, explained by the invention’s author (Sandeep Acharya): “Think of Two Powerful Magnets. One fixed plate ...
