Some thermal pastes are good for air cooling, others for liquid cooling, some are generally efficient, others are not. But as our colleague Igor Wallosek discovered, there is a thermal paste that stinks and damages coolers. That thermal paste — Amech (Aimac) SGT-4 made in South Korea — appears to be quite popular in online stores around the world because it is cheap and gets favorable user reviews. Yet, SGT-4 appears to be a chemically reactive blend that stinks due
Teacher uses cheap laser and solar panel to transmit wireless sound — iPad powers home project that was inspired by solar panel making noise when attached to speaker
Phil, a high school chemistry teacher and YouTube creator, noticed that a small solar panel emitted a faint sound when connected to a speaker and exposed to light. From this, he deduced that he could transmit sound wirelessly using light, with the solar panel acting as a receiver. So, he decided to build a wireless transmitter using his iPad, a solar panel, and a cheap speaker, and shared the short build on his YouTube channel .
The first thing he did was
Carry your favorite apps wherever you go with PortableApps
Recently, I built a PC toolkit that had all the tools that I would need to repair a broken computer. Using Ventoy , it even included a USB flash drive with multiple Linux distros, rescue ISOs, and even a copy of Windows 11 ready to install. What it didn’t have were the apps that I typically use to overcome issues and solve problems.
Sure, I can install these every time I move to a new computer. Or I can work
Hackers slip malware inside blockchain to steal cryptocurrency — EtherHiding embeds malicious JavaScript payloads in smart contracts on public blockchains
A North Korean state-sponsored hacking crew is now using public blockchains to host malicious payloads, according to new research from Google ’s Threat Intelligence Group (GTIG). The campaign, which leverages a technique known as “EtherHiding,” is the first documented case of a nation-state actor adopting smart contract malware delivery to evade detection and disrupt takedowns.
Google attributes the activity to UNC5342, a group it links to the long-running “Contagious
be quiet! System Power 11 550W power supply review
Tom's Hardware Verdict
The Be Quiet! System Power 11 550W represents a sensible approach to entry-level power supply design, successfully incorporating ATX 3.1 compatibility while maintaining the German manufacturer's reputation for quiet operation. Though it achieves ra espectable 80 Plus Bronze efficiency and includes the increasingly important 12V-2x6 connector, this unit cannot escape the fundamental constraints of its decade-old platform architecture and budget component selection.
Nvidia and TSMC produce the first Blackwell wafer made in the U.S. — chips still need to be shipped back to Taiwan to complete the final product
Nvidia and TSMC on Friday announced they had reached a significant milestone with the manufacturing of the first production Blackwell wafer at Fab 21 near Phoenix, Arizona. The achievement of making one of the most complex chips in history in the U.S. has strategic, symbolic, and political importance for both companies, but there is a major catch.
"This is a historic moment for several reasons," said Jensen Huang, chief executive of Nvidia, at the commemorative event. "It

Optical drive demand surges amid Windows 10 retirement — Japanese users switching to Windows 11 are buying up Blu-ray drives
Microsoft ended official support for Windows 10 last week, which means an entirely new population has been forced to move to Windows 11, or be left behind. While the tech-savvy gentry can work their way around the artificially imposed red tape, most people would want to adhere to policy. That's what's happening in Japan. According to IT Media , shops in Tokyo's bustling Akihabara area are suddenly experiencing a meteoric rise in Windows 11 demand,
Jensen says Nvidia’s China AI GPU market share has plummeted from 95% to zero — the Chinese market previously amounted to 20% to 25% of the chipmaker's data center revenue
Nvidia CEO Jensen Huang said last week that the company’s share of China’s advanced AI accelerator market has collapsed from roughly 95% to zero as US export controls continue to bite. The comment came during a live interview at Citadel Securities’ Future of Global Markets 2025 event in New York on October 6, in which Huang said, “At the moment, we are 100% out of China,” adding, “We went
Secret SpaceX satellites are transmitting mysterious signals on the wrong spectrum — a classified network caught sending data on the uplink frequency
An amateur satellite tracker accidentally discovered a subset of classified military SpaceX satellites that are transmitting data on the wrong radio frequency. According to NPR , Canadian Scott Tilley found the mysterious signal while working on his hobby of monitoring satellites at home, when he inadvertently set his system to scan for radio frequencies that usually didn’t have traffic. To his surprise, he saw a signal emanating from space in the 2025-2110 MHz band, which satellites use to receive
