PCs with water cooling are not 100% silent. While water cooling can significantly reduce the noise generated by traditional air cooling systems, there are still other components in a PC, such as the power supply, graphics card, and hard drives, that can produce noise. Additionally, the pump and fans used in water cooling systems can also generate some level of noise, although it is generally quieter than air cooling. Overall, while water cooling can greatly reduce noise, it may not make a PC completely silent. **

It can be challenging to find a good gaming PC for up to 100 euros, as most gaming PCs are typically more expensive due to the high-performance components required. However, you may be able to find a used or refurbished gaming PC within this price range. Look for PCs with at least 8GB of RAM, a dedicated graphics card, and a decent processor. Keep in mind that at this price point, you may need to make some compromises on performance and features. Consider looking for deals on online marketplaces or local classifieds to find the best value for your budget. **

A temperature of 100°C is harmful for PCs when it is sustained for an extended period of time. Most PCs are designed to operate within a safe temperature range, typically between 30-60°C. When a PC's temperature exceeds this range, it can lead to overheating, which can cause damage to internal components such as the CPU, GPU, and motherboard. It is important to monitor and manage the temperature of a PC to prevent overheating and potential damage. **

Yes, all PCs running Windows support network operation. Windows operating systems have built-in networking capabilities that allow PCs to connect to local area networks (LANs) and the internet. Users can set up and manage network connections, share files and printers, and access other devices on the network. Additionally, Windows includes features such as Network and Sharing Center and HomeGroup to facilitate network operations. Therefore, all PCs running Windows are capable of supporting network operation. **

A 16000 DSL connection, also known as a 16 Mbps connection, should be able to support 7 PCs for basic internet browsing, email, and light streaming. However, if all 7 PCs are engaging in high-bandwidth activities simultaneously, such as HD video streaming or online gaming, the connection may become slow and experience latency. It's important to consider the bandwidth needs of all 7 PCs and the potential impact on the overall network performance. If heavy internet usage is anticipated, it may be beneficial to upgrade to a higher speed connection to ensure a smooth and reliable internet experience for all users. **

Some PCs have their fans briefly running at 100% when starting up to perform a quick self-test and ensure that the fans are functioning properly. This helps to prevent overheating issues by ensuring that the cooling system is working effectively from the moment the computer is powered on. Running the fans at maximum speed during startup also helps to quickly cool down any components that may have heated up while the computer was off. **

Some PCs have their fans running at 100% speed briefly during startup to perform a system check and ensure that the cooling system is functioning properly. This helps to prevent overheating and potential damage to the components. Once the system check is complete and the PC reaches a safe operating temperature, the fan speed will adjust accordingly to maintain optimal cooling performance while minimizing noise levels. **

The fans on some PCs briefly run at 100% speed when starting up to perform a quick self-test and ensure that they are functioning properly. This initial burst of maximum speed helps to clear out any dust or debris that may have accumulated on the fan blades, ensuring optimal performance. Once the self-test is complete and the system confirms that the fans are working correctly, they will adjust to their normal operating speed based on the system's temperature and workload. **
