  You can't use a laptop on your lap any longer.

We've been calling the portable computer laptop for a long time. Times change and for good reason, we've been advised not to place a portable computer on our lap. I have preached for some time that you shouldn't because it was harmful to the laptop because it interfered with the air flow to the CPU and GPU heat exchangers. As it turns out, it's not good for another reason.

The heat and electronic frequencies produced by the portable computer can harm a man's ability to have children. I know many of you will rush to put the computer in your lap for that reason. Frankly, I personally don't want anything to interfere with my sex life.

On the other hand, placing the portable computer on a hard surface can prolong the life of the computer, But over time, the heat exchanger can clog by vacuuming dust into the computer. To combat this problem, I cut a coffee filter the size of the opening of the fan intake and tape it over the opening, taking care not to block any of the vent with the tape. I'm still using the portable computer with no heat problems for over five years now. I change the filter when it looks dirty.

Sounds like a good idea and simple to do. Did you check CPU, system, and HDD temps before and after applying the filter(s)? I'd be curious as to any findings.

Also, if you use an ultrasonic humidifier in the room and don't use water that has all the solids removed (e.g. distilled water) the humidifier will emit microscopic white "dust" particles into the air. The particles wouldn't show on a typical white coffee filter, but will quickly reduce its efficiency so a regular change schedule might also be warranted. (For the same reason, 3 hard drive manufacturers I've talked with recommend using either environment-hardened HDDs or to use only distilled water when ultrasonic humidifiers are in use as the "dust" they produce will quickly plug-up HDD air filters.)

No John, I haven't checked the temperatures. This was part of a repair of a laptop I got by donation. I cleaned the dust from the unit and replaced the thermal paste of the CPU. Installed the filter. Because I don't recommend this brand of laptop, I kept it. I mainly use it to play music in my shop. Here's a look at what I did.
