Aluminum laptop fan

It’s basically a cooling pad or stand — a platform on which you place your laptop — that incorporates one or more fans to blow air under (or around) the laptop, helping dissipate heat faster than passive cooling alone.

Specifications

• <p>Fits laptops roughly <strong>12”–17”</strong> (so works with most standard notebooks). &nbsp;</p><p><br></p><p> • Fans: <strong>4 × 70 × 70 × 10 mm</strong> fans. &nbsp;</p><p> • Rated Voltage: <strong>5 V DC</strong> (i.e. powered from a USB port). &nbsp;</p><p> • Rated Current: 0.6 A total (≈0.15 A per fan) → Power consumption ≈ <strong>3 W total</strong>. &nbsp;</p><p> • Fan Speed: ~<strong>2000 RPM</strong>. &nbsp;</p><p> • Noise Level: typically <strong>low</strong>, e.g. &lt; ≈ 22 dBA. &nbsp;</p><p> • Build: <strong>Aluminum surface / frame</strong>, sometimes with non-slip pads to stabilize laptop. &nbsp;</p><p> • Adjustability / Fit: many are designed to support a range — often up to 15.6” or 17” laptops. &nbsp;</p><p><br></p><p><strong>Other variations</strong></p><p><br></p><p> • Some pads use a <strong>single large fan</strong> (instead of multiple small ones), with fan speeds e.g. <strong>1000–1400 RPM</strong>, producing a quieter operation (good for office, study, etc.). &nbsp;</p><p> • Power and connectivity: almost always <strong>USB-powered</strong> (so you don’t need a separate power brick) — you plug into a laptop or power bank. &nbsp;</p><p> • Extra features: some include <strong>adjustable height/angle</strong>, <strong>foldable or portable design</strong>, <strong>rubber/ silicone non-slip pads</strong>, and even <strong>RGB lighting</strong> on gamer‑oriented models. &nbsp;</p><p><br></p><p><strong>Performance effects</strong></p><p><br></p><p> • The aluminum helps <strong>conduct and spread heat away</strong> from the laptop’s bottom. &nbsp;</p><p> • The fans increase airflow, which helps <strong>dissipate heat faster than passive cooling alone</strong> — useful when the laptop’s internal cooling is under heavy load (long sessions, gaming, video editing, high ambient temps). &nbsp;</p><p> • Models with multiple fans or larger fans tend to produce <strong>more airflow and better heat dissipation</strong>, but possibly at a cost of <strong>higher noise</strong> (though many aim to stay “quiet”). &nbsp;</p><p><br></p>
