It depends on the store's return policy. Some stores may allow returns for a full refund within a certain time frame, while others may only offer store credit or exchange for a different item. It's best to check the store's return policy or contact customer service to find out the specific details for returning a handheld fan purchased for 130 euros. **

Water cooling and fan cooling are both methods used to dissipate heat from computer components, but they work in different ways. Fan cooling uses air to remove heat from the components, while water cooling uses a closed-loop system with a pump to circulate water or coolant to absorb and remove heat. Water cooling is generally more efficient at dissipating heat and can be quieter than fan cooling, but it is also more complex and expensive to install. Fan cooling, on the other hand, is simpler and more affordable, but may not be as effective at cooling high-performance components. **

The better USB fan depends on your specific needs and preferences. If you are looking for a portable and compact fan to use on-the-go, a smaller USB fan with a flexible neck may be more suitable. On the other hand, if you need a more powerful fan for cooling a larger area, a USB fan with multiple speed settings and a larger blade size may be a better option. Consider factors such as size, power, noise level, and adjustability when choosing the best USB fan for your needs. **

A USB fan is generally not dangerous as long as it is used properly and according to the manufacturer's instructions. However, like any electrical device, there is a potential risk of overheating or electrical malfunction if the fan is not maintained or used correctly. It is important to ensure that the fan is placed on a stable surface, not obstructed, and not left unattended for long periods of time to minimize any potential risks. **

Yes, the USB fan is usable. It can be plugged into any device with a USB port, such as a computer or power bank, making it convenient for use in various settings. The fan provides a cooling breeze and can be easily adjusted to different angles, making it suitable for personal use at a desk or while on the go. Overall, the USB fan is a practical and functional device for staying cool in different situations. **

A USB PC fan is a small fan that can be powered by connecting it to a USB port on a computer or other electronic device. It is designed to provide additional cooling for the device by circulating air and helping to prevent overheating. USB PC fans are often portable and can be easily moved and adjusted to provide targeted cooling for specific areas of a computer or laptop. They are a convenient and affordable way to improve the airflow and temperature regulation of electronic devices. **

You can buy a handheld fan at electronic stores such as MediaMarkt, Saturn, or other similar retailers. These stores often carry a variety of electronic and small appliances, including handheld fans. Additionally, you can also find handheld fans at department stores, home goods stores, and online retailers. **

The choice between a 120mm fan and air cooling depends on the specific needs of the system. A 120mm fan is a component of air cooling, so it is not a matter of choosing one over the other. Air cooling typically involves a combination of fans and heatsinks to dissipate heat from the CPU or other components. A 120mm fan can be a good option for providing efficient airflow within a system, but the effectiveness of the cooling solution will also depend on factors such as the size of the heatsink, the thermal design of the components, and the overall airflow within the case. **
