Cooling smarter: reducing building electricity use

As summers get hotter, AC demand climbs, but researchers are pursuing a mix of strategies—blocking heat entry with smart windows and shading, reflective roofs, and passive cooling materials; improving efficiency with desiccant-based cooling, built-in storage to ease peak load, and smarter ventilation—tailored to climate and building type. No single fix fits all, but reducing peak demand can lessen the need for new power generation while keeping people cool and safe.

Liquid cooling could curb data centers' water hunger

Rising AI workloads are driving a boom in data centers that currently rely on water-intensive cooling. Air cooling is energy-inefficient and its evaporative methods strain water supplies; liquid cooling—especially direct-to-chip systems—could dramatically cut both water use and electricity, with potential for heat reuse and rainwater harvesting. Adoption faces retrofit costs and safety concerns, so a gradual shift toward liquid cooling and smarter water management may offer the best path to reducing the sector’s environmental footprint.

Metal table cools gaming laptops, dropping temps up to 15°C, Reddit finds

A Reddit user tested a gaming laptop on a wooden desk versus a metal table in an air-conditioned room and found temps dropped from about 80–90°C on wood to 75–83°C on metal during Cyberpunk 2077. The likely reason is that many laptops pull cooler air through bottom vents, and a metal surface conducts heat away, reducing heat buildup under the chassis. The metal table does not actively cool like fans or pads, and users should avoid ice or condensation risks. Practical tips include keeping bottom vents clear, cleaning dust, lifting the rear of the laptop to improve airflow, and using a cooling pad if needed in some setups.

AI’s unseen water toll could reach 765 billion litres in 2025

A peer-reviewed model estimates AI-related water use in 2025 could range from about 312.5 to 764.6 billion litres (peaking at 765 billion), driven by data-centre cooling and electricity production. It’s not a global meter reading—it's a boundary-bound estimate built from limited disclosures, meaning real totals are uncertain. Water used in manufacturing and construction is excluded. Advances in cooling and cleaner power can cut on-site use, but transparency about where AI workloads run and site-level water/power metrics is essential to clarify the footprint.

iPhone 17 Pro’s One-Year Checkup: Durable Build, Strong Battery, Cool Under Pressure

After about a year with the iPhone 17 Pro, durability remains solid thanks to Ceramic Shield 2 with only faint edge scratches; orange color fading rumors haven’t materialized on the reviewer’s device. Battery life easily covers a full day of heavy use, aided by the new vapor‑chamber cooling, though iOS 27 beta can cause higher temps and brief performance dips. With talk of a modest upgrade in the iPhone 18 Pro, the 17 Pro remains a strong buy for those upgrading from older iPhones.

Towering chimney cooling shaves nearly 19°C off CPU temps, der8auer finds

German overclocker der8auer built a 110 cm tall 3D-printed PLA tower to test the chimney effect. With a Ryzen 7 9800X3D and a 240 mm radiator at 100 W, the tall chimney pulled air through the radiator, causing coolant temps to drop to ~50–55°C and reducing CPU temps by about 19°C (from ~90°C to ~71°C). While the experiment proves a real chimney can boost cooling, the author concludes that conventional fans remain the sensible option for most builds due to height and practicality.

Pulsar's Feinmann FO1 Noctua Edition Introduces Internal Cooling in a 73g Gaming Mouse

Pulsar reveals the Feinmann FO1 Noctua Edition, a lightweight gaming mouse that houses a 40mm Noctua NF-A4x10 PWM fan inside the shell to blow air directly into the palm for sweat-free sessions. It uses the XS-2 sensor with up to 42,000 DPI and 8 kHz polling, and weighs about 73g (up from the original 46g). The shell design features large vents for sustained airflow, and the official launch is set for July 21, 2026; MSRP and regional availability have not yet been announced.

Orbiting Data Centres: Radiators as the Quiet Heat Sink

Cooling a data centre on Earth can consume 10–30% of its energy budget and requires vast water use; in space there is no air or water, so heat must be dumped as infrared radiation through massive radiator panels. Those radiators become the limiting factor for megawatt-scale data processing in orbit, complicated by solar heating and the need to keep panels large enough to reject heat yet feasible to launch. The European Space Agency has studied orbital data centres (ASCEND), a startup (Starcloud) has launched an AI satellite, and Google is exploring space-based designs, signaling a staged path: begin with small processor counts in orbit, increase power budgets, then deployable radiators, and finally scalable heat rejection—subject to whether radiators can scale without becoming prohibitively large given launch costs.

Mac Studio to Jump to M7 Ultra in 2028 With Enhanced Cooling

Bloomberg’s Mark Gurman says Apple plans two Mac Studio refreshes: an M5 Ultra this year and a more substantial M7 Ultra in 2028, skipping the M6 entirely. The M7 Ultra is expected to feature a redesigned inner architecture and a better heat sink for improved thermals, while the M5 Ultra is not anticipated to have a major redesign. Memory options have been tested up to 768GB, though supply constraints could limit offerings, and launch timing for the M5 remains unclear after delays tied to memory chips and price increases.

Mini-ITX Meets 3D Printing: a Full PC in a Steam-Machine-Sized Case

Hackaday covers a Printables project that packs a Mini-ITX motherboard, a small-form-factor PSU, and a full discrete GPU into a 3D-printed case the size of a Steam Machine, done with AMD's Jacob Terkelsen. The build highlights Valve's Steam Machine cooling differences, suggests adding ventilation, and notes thermal and performance questions as real-world thermals and gaming benchmarks remain to be seen.

Amazon reports 2.5B gallons of data-center water use in 2025, says it’s more efficient

Amazon published its first annual water-use data for global data centers, reporting 2.5 billion gallons in 2025 (about 0.12 liters per kWh), a 2% decline from 2024 as it expanded capacity. The company argues its facilities are seven times more water-efficient than the industry average and rely mostly on air cooling, with evaporative cooling during peak heat, but the figures exclude indirect water use at power plants and water for building new centers; Google reportedly uses more water per kWh in the cited charts, and comparisons often focus on Gemini AI data centers rather than all of Amazon’s operations, all against a backdrop of Seattle’s data-center moratorium.

Apple Moves On from Titanium: Aluminum Pro iPhones Boost Cooling and Battery Life

Apple shifted the Pro lineup from a titanium frame to an aluminum unibody with a vapor chamber in the iPhone 17 Pro, citing improved heat dissipation and longer sustained performance (up to 40% better in some tasks). Titanium remains used in the iPhone Air, but for Pro models aluminum offers design and thermal advantages, including room for a larger camera module and bigger battery, suggesting titanium may not return to the Pro line for now.

Google rolls out a water-conscious data-center framework

Google unveils a formal water-management framework for its data centers, pledging to return more water to local watersheds than it uses by 2030, cut water-intensive cooling in stressed regions, fund local water upgrades, pursue alternatives like reclaimed wastewater, and disclose annual usage; the move packages long-standing practices as a standard and aims to push industry adoption. In 2024 Google used 7.2 billion gallons of freshwater and replenished about 4.5 billion (64%), with two-thirds of centers using evaporative cooling and the rest relying on air cooling or recycled water, illustrating the trade-off between preserving water supplies and electricity use.
