This article covers エレコム ワイヤレスマウス Bluetooth Slint M-TM10BBBU.

Overview

The ELECOM SX-CL3WH is a USB-powered laptop cooling pad designed to prevent thermal throttling and improve long-term reliability of notebooks. It features a single 120mm silent fan with a subtle blue LED, running entirely from USB bus power — no separate AC adapter required. At just 30mm thick, the pad is slim enough for daily carry. The aluminum panel helps dissipate heat efficiently, while rubber feet on the bottom prevent slipping on a desk surface. The white exterior blends well with most laptop designs, giving it a clean, unobtrusive appearance. This product targets users who run processor-intensive tasks on their laptops for extended periods — whether creative work, video conferencing, or marathon gaming sessions. For those whose laptop runs hot even under moderate loads, this pad offers a simple, affordable cooling upgrade.

Connectivity & Compatibility

The cooling pad connects via a standard USB-A male plug to any laptop USB port. Both fan operation and LED lighting are powered solely through this connection; no external power brick is required. It supports laptops from 12 to 17.3 inches, covering the vast majority of mainstream notebooks. On the back edge, the pad includes a built-in 2-port USB-A hub, allowing you to plug a mouse, USB flash drive, or external storage device without sacrificing a port on your laptop. There's also a cable routing slit to keep the USB cable neatly aligned with the back of the notebook. The device works with any laptop that has a USB port — Windows, macOS, and ChromeOS are all supported. One limitation: there is no speed control for the fan; it runs at a fixed RPM whenever connected. Users looking for adjustable airflow should look at models with a manual switch or PWM support.

Product Info

The SX-CL3WH launched around fall 2023 with an expected street price of roughly ¥2,500 to ¥3,500 in Japan. It's available through major electronics retailers and ELECOM's official online store. The warranty period is the standard one year from the manufacturer. The package contents are minimal: the cooling pad itself and a USB cable (approximately 60cm). This product sits squarely in the entry-to-mid-range segment. Its 120mm single-fan design is simple, but the aluminum panel and rubber feet provide a quality feel that justifies the price. There are larger models with 130mm or even 200mm fans for higher heat loads, but for average office or light creative work, the SX-CL3WH offers an excellent balance of performance, noise, and portability.

Best Use Cases

  1. Business professionals working desk jobs For users who keep their laptop docked or on a desk for eight-hour stretches, this pad serves dual duty as both a cooler and a USB hub. You can plug your mouse and keyboard into the back ports, reducing cable clutter. However, if you own a high-end gaming laptop that pushes 100W+ CPU/GPU loads, the cooling capacity may be insufficient — consider a more aggressive cooling solution in that case. 2. Users in quiet environments (cafés, libraries, co-working spaces) The fan is rated at around 18 dB(A), which is whisper-quiet — generally inaudible in a quiet room. This makes it a strong candidate for shared workspaces where fan noise can be distracting. If you demand absolute silence, a passive cooling stand (with no fan) would be a better choice, though it won't offer the same active thermal relief. 3. Travelers with compact laptops Weighing about 360g and measuring only 30mm thick, this pad slips easily into a laptop bag. It works especially well with 13-inch ultrabooks that tend to have limited internal thermal capacity. But if you use a 15.6-inch or larger notebook, double-check the pad's dimensions — the width might be slightly short for a stable fit. In summary, the ELECOM SX-CL3WH is a capable entry-level cooling pad that prioritizes silence and portability over brute-force airflow. It's ideal for anyone wanting to reduce laptop temperatures during daily office or home use without adding fan noise to their workspace.
