# How to tell whether your computer needs air conditioning: temperatures, fans and when to worry

How to tell whether your computer needs air conditioning: temperatures, fans and when to worry How to tell whether your computer needs air conditioning: temperatures, fans and when to worry Every July we get the same warnings: "my computer switches off by itself", "the laptop is burning underneath" or "the fan sounds like a plane taking off". Summer heat shows no mercy, and computers feel it as much as we do. Why does heat affect computers so much? A computer constantly generates heat just by being switched on. The processor, the graphics card and other components produce heat that the internal cooling system is responsible for removing. The problem is that this system is designed to work within a reasonable ambient temperature range. When the room is already at 30-35 degrees, the computer finds it much harder to expel its own heat. It is like trying to cool down in a sauna: however much you sweat, the environment does not help. Which temperatures are normal and which are not? This depends on the component, but here are the general references we usually work with: Processor (CPU) at idle: Between 30-45°C is normal. Above 70-80°C in normal use (not in demanding tasks) it starts to be a reason for attention. Processor under heavy load: Up to 80-85°C can be acceptable on many modern processors for a while. If it stays constantly near 90°C or more, there is a real problem. Graphics card: Similar to the processor, up to 80°C under load is usually within normal range on many models, but it is worth checking the manufacturer's specifications. Hard drive or SSD: It should stay between 30-50°C. If it constantly exceeds 60°C, it is worth checking. These ranges are indicative and vary depending on the specific model of each component, but they serve as a first reference to know whether something is out of the ordinary. Signs that your computer is suffering from the heat The fan is much louder than usual It is the first sign and the easiest to detect. The fan works harder because it is trying to compensate for a higher than normal temperature. The computer switches off by itself without warning This is a protection of the system itself. When the temperature reaches a critical limit, the computer shuts down to avoid damaging components. If this happens to you, it is not a whim of the computer, it is a real alarm. Performance drops for no apparent reason When a processor gets too hot, it automatically reduces its speed to generate less heat. This means the computer runs slower than normal, especially on demanding tasks. The casing or the keyboard area is hot to the touch It is normal for a laptop to warm up a little, but if you notice it is really burning on the base or near the keyboard, it is a sign that the cooling system cannot cope. What you can do yourself before worrying Check that the ventilation grilles are not blocked Accumulated dust is the number one enemy of cooling. If you have not cleaned the inside of the computer for a while, the problem may not be just the summer heat, but accumulated dirt. Do not cover the air outlets Using the laptop on the bed, the sofa or any soft surface blocks the air outlet on the underside. A hard, flat surface helps the computer breathe much better. Avoid direct sunlight on the computer It seems obvious, but it is one of the most common mistakes. A computer next to a window with direct sun in July can raise the ambient temperature by several degrees just because of that. Give it breaks during the hottest hours If you can avoid very demanding tasks (video editing, games, rendering) during the hottest hours of the day, the computer will thank you. When is it time to ask for help? If, after checking the above, the computer still switches off by itself, the fan sounds as if it were about to take off, or you notice that performance has clearly dropped, it is a good time for a proper check. Often the problem is not just July's heat, but that it adds to dried-out thermal paste, dust accumulated over months or a fan that is already at the end of its life. Summer heat simply brings to light a problem that was already there. At Bytechip we carry out a diagnosis with real temperature-measuring tools before recommending anything. If the problem can be fixed with a clean and a change of thermal paste, we are not going to sell you a new computer. ← Back to the blog
