every time i play my nintendo switch, in handhelp mode it get warm when playing,. do i need to replace the original, joy-cons with some new ones

It's normal for the Nintendo Switch to get warm when playing in handheld mode, especially during graphically intensive games or extended play sessions. The console is designed to dissipate heat, and some warming is expected. However, if you're experiencing excessive heat, overheating issues, or if the console is consistently uncomfortable to hold, you might want to consider the following: 1. **Check for Obstructions**: Ensure that the air vents are not blocked and that dust or debris isn't accumulating in the vents. 2. **Software Updates**: Make sure your Switch's software is up to date, as updates can sometimes improve performance and efficiency. 3. **Joy-Con Replacement**: Replacing the Joy-Cons typically won't affect the heat issue. They are primarily responsible for controls, not the operation of the console's hardware that generates heat. 4. **Functionality**: If the Joy-Cons are malfunctioning (like disconnecting frequently or not charging), you may consider replacing them, but they shouldn't impact the core temperature of the system. 5. **Cooling Solutions**: If you're consistently finding the unit too warm, you can look into cooling solutions like fan attachments or stands that promote better ventilation. If the heat is accompanied by performance issues, frequent crashes, or if the system becomes unresponsive, it may be worth consulting Nintendo’s support or considering repairs.
