Hi everyone! I just rearranged my room and ended up placing my PC setup right in front of a radiator because of the limited space. I'm really concerned about the potential damage the heat might cause to my computer if I use the radiator during the colder weather. I've avoided turning it on for the past couple of days as a precaution. Could the heat from the radiator harm my PC or the other electronics on my desk? Any advice would be greatly appreciated!

I'd advise against having your PC close to the radiator. Even though the PC has its own cooling system, the extreme heat can affect it over time. It might actually be a good idea to reposition your setup just to be safe.
Excessive heat can definitely lead to performance issues or even unexpected shutdowns. If you’re not doing heavy lifting like gaming or processing, you should be fine. But seriously, give your PC a good dusting with compressed air; a clean PC runs cooler!
If moving it isn’t an option, you could use a piece of cardboard to create a heat shield between the radiator and your PC. Just make sure there’s an air gap for ventilation, and maybe cover it with aluminum foil to reflect some heat away.
If you can elevate your PC onto a desk or a shelf, that would really help. The further away from the radiator, the better! It’s not the end of the world if it’s nearby, but try to minimize heavy usage like gaming if it’s close.
Your CPU runs at temperatures around 80-100°C, while a radiator typically stays around 30°C. So, the radiator's heat shouldn’t drastically affect your PC performance. But remember, your PC needs to draw in cooler air to keep everything working smoothly, so keeping it near the radiator isn’t ideal.
Honestly, just move your PC to a different spot if you can. It’s the safest option here!

That’s not entirely accurate. If your PC's fans are pulling in hot air from the radiator, it could struggle to cool effectively and might slow down during intensive tasks.
