A screen running at 75\u00b0C instead of 35\u00b0C may last 40,000-50,000 hours instead of 100,000+.<\/p> <\/details><details> <summary>Q: Do outdoor LED displays need air conditioning?<\/summary> <p>In most climates, fans are sufficient. In extreme heat (desert, tropical, direct sun all day), AC may be required. Ask your supplier for climate-specific recommendations.<\/p> <\/details><details> <summary>Q: Why do fine-pitch displays run hotter?<\/summary> <p>Fine-pitch displays have more LEDs per square meter. More LEDs = more heat. P1.5 displays may need 2-3x more cooling than P4 displays of the same size.<\/p> <\/details><details> <summary>Q: Can I use an indoor display outdoors if I add cooling?<\/summary> <p>No. Indoor displays lack weatherproofing (IP rating) and have insufficient brightness. Adding cooling does not solve those problems. Buy an outdoor-rated display.<\/p> <\/details><details> <summary>Q: How do I know if my display is overheating?<\/summary> <p>Signs include: fans running at maximum constantly, brightness fluctuating, color shifts, random shutdowns, or error messages from the control software. Monitor temperature data if available.<\/p> <\/details><details> <summary>Q: Does IvanLED provide temperature monitoring?<\/summary> <p>Yes. Our outdoor displays include temperature sensors with remote monitoring capabilities.
