Laptop Heat Problems (also see how Laptraxx improves Ventilation)

Heat can crash your laptop processor

Modern laptops run fast microprocessors that can generate a lot of heat. The heat is mainly vented out of the bottom of the laptop but ventilation effectiveness is reduced when the laptop is placed on a solid surface or on your lap. A hot laptop can suffer from reliability problems and a system that overheats can fail. [1]

Heat can crash your laptop hard drive

Hard disk drives can overheat and crash, causing you to lose valuable data! Manufacturers recommend normal working temperature of 95-104°F  (35-40°С). At temperatures from 104-122°F  (40-50°С) you double the chance of a hard drive crash!

Laptop heat can cause skin burns

A hot laptop can be uncomfortable to use in your lap. The heat from some laptops can be enough to cause superficial skin burns, even through clothing!

The Lancet medical journal reports the case of a healthy 50-year old scientist, fully dressed in trousers and underpants, who burned his genital area after placing his laptop on his lap for an hour.  While using the laptop he did occasionally feel the heat and a burning feeling on his lap and proximal thigh. Two days later he had blisters that burst and developed into infected wounds. [2]
 

Laptop heat can reduce fertility

In addition to a hot laptop being uncomfortable to use, if you are a man, it may reduce your fertility. [3]

A recent research study of 29 healthy male volunteers measured right and left scrotal temperature in every 3 minutes in two separate 60 min sessions: sitting and working with and without the laptop on the thighs. With the laptop in the lap, skin temperature was significantly higher (P<0.0001).

The researchers concluded that working with a laptop positioned on the thighs causes significant elevation of skin temperature in the groin as a result of heat exposure and posture-related effects. Long-term exposure to repetitive hot laptop use in the lap may have a negative impact upon fertility, specifically in teenage boys and young men.
