Laptop cooling pads have been around for decades, and the idea has always been simple: provide extra air to blow through a laptop that's otherwise restricted by its own cooling system. In theory, more air means lower temperatures-and, ultimately, better performance. This is the whole idea of the power modes that exist in Windows, which ramp up the RPMs (rotations per minute) of the fans to add more air to both improve performance.

According to the company, the compressor integrates an ultra-high-speed electric motor exceeding 160,000 rpm combined with an oil-free foil bearing system. The architecture is designed to deliver reduced package size, lower weight and lower noise levels compared with conventional scroll compressors. Garrett states that the system is up to 50% smaller, 30% lighter and 10 dB quieter than traditional scroll-based solutions. The compressor is engineered for compatibility with 400V to 800V heat pump systems and supports low-pressure, low-GWP refrigerants.

Now say you want to run some modest AI stuff. That's a bigger job, so let's scale up our cubical computer with edges twice as long as before. That would make the volume eight times larger (2 3), so we could have eight times as many processors, and we need eight times as much power input-2,400 watts. However, the surface area is only four times (2 2) larger, so the radiative power would be about 4,000 watts.

In the not-so-distant past, the solution for boosting the speed of an aging, sluggish PC was to add more RAM or upgrade the processor. Now, the way to sail over that speed bump is to get a new storage drive, and there's no better storage upgrade for performance than fitting your system with an M.2 drive. Also: What is MoCA 2.5? How this low-cost networking option can seriously improve your internet There is no shortage of excellent M.2 drives out there, but if you're looking for high-end performance and stability when the going gets tough, the is well worth a look.

CATL says its new 5C batteries will retain 80% of their capacity after 1,400 charge-discharge cycles at 140F (60C). With a theoretical range of 372 miles (600 km) per cycle, that works out to a total of 522,000 miles (840,000 km) in what CATL describes as Dubai summer heat. At a milder ambient temperature of 68F (20C), which is closer to the ideal operating temperature for lithium-ion batteries,

The Poco F8 Ultra sits atop the Poco portfolio, offering solid all-around performance at a sub-flagship price. But ever wondered what's inside, especially with the built-in subwoofer? Well, the guys at PBKreviews have done a complete teardown showing off the internals, and there are some interesting findings. Let's start with repairability. Previous Poco F generations have been criticized for being hard to repair, but the F8 Ultra appears to have improved on that aspect.

For starters, the Taycan's range increased from a maximum of 246 miles for model year 2024 to more than 300 miles for the current model year. Its peak charging rate also increased from 270 kilowatts to 320 kW, reducing the 10-80% charging time by roughly 3.5 minutes when plugged into a fast enough DC fast charger. Behind the scenes, Porsche made a raft of changes to make all of that possible.

Gaming handhelds are supposed to fit in your hands, but AMD's new Strix Halo processors generate serious heat and drain batteries faster than you can finish a boss fight. The GPD Win 5 and OneXFly Apex responded by strapping external battery packs to their backs, which works, but looks like your handheld is wearing a fanny pack in the wrong spot. It's practical but awkward, and it raises an obvious question: if you're adding external batteries anyway, why not just make the whole device bigger?

First off, the ProArt P16 has a lightweight physical design, making it easy to carry around. I found the keyboard to be too mushy for my liking. It doesn't have a great typing feel, but the keycaps are quiet, so that's a plus. The touchpad takes up a large portion of the wrist rest, enabling better comfort and ease of use. On either side of the keyboard is a pair of Harman/Kardon speakers delivering strong audio output.

At the AI Infra Summit this week, simulation savant Cadence added Nvidia's biggest iron, the GB200 NVL72 Superpod, to its digital twin fire. At roughly a megawatt, the compute cluster is among the GPU giant's most complex compute platforms to date. Each Superpod consists of eight 120 kilowatt NVL72 racks containing more than 500 Blackwell GPUs and 288 Grace CPUs capable of churning out a combined 11.5 exaFLOPS of the lowest-precision compute money can buy.
