Protect your electronics from heat damage by installing a cooling fan in your entertainment center

01 Jun

Entertainment center exhaust fanReach your hand behind your receiver or TV. Do you notice that it’s warmer back there? You’re feeling the residual heat given off by hard-working electronic devices. Unfortunately, high temperatures contribute to the failure of all kinds of small electronic components, from printed circuit boards to resistor, capacitors, and batteries. It’s a conundrum: audio and video electronics produce heat, and yet heat is seriously hazardous to their health. Between the receiver, two video-game consoles, and the TiVo, my entertainment center can get quite hot, especially during the summer. Since the TiVo (and, to a lesser extent, the consoles) is on at all times, it never really cools down inside the cabinet.

Computer designers tackled this problem long ago: most PCs include a rear exhaust fan and one or more open grills near floor level to admit fresh air so the computer does not overheat. Now that we’re putting PC-style devices in our living rooms, we need to treat the entertainment center like a giant PC case.

To keep my equipment cool, I installed an exhaust fan in the back of my entertainment center. Adding an exhaust fan that pushes air out of the case creates an effective negative pressure in the case and draws in new air from every open point. Of course, you need an inlet hole for air to enter the case for this process to work. Hot air rises, so you want an exhaust hole near the top to remove heated air and an inlet hole near the bottom of your container to draw in cooler air.

You spent a lot of money on this stuff! Make sure your equipment keeps working for as long as possible by keeping its critical parts cooled. All you need to do is cut a minor hole in the back of your entertainment center, find a suitable fan, and decide how to power it. I promise to make it simple. Read the rest of this entry »

 

Convincing your parents to get a TiVo Premiere and explaining how to set it up

06 Jun

Friends don’t let friends watch nothing but standard-definition on an HDTV. I owed my parents no less, I thought. Forget that they have always resisted my campaigns to have them buy new gadgets that I thought they would enjoy. As always, this was for their own good.

They took to the DVR revolution rather well. It didn’t take them long to fall in love with their original TiVo (Series 2) and fill it with episodes of NCIS and WWII specials. Getting them to transition to a larger TV took longer, but now they’re equally thrilled with that, too.

It follows that I, never content to let them remain happy with what they have, pointed out that they still needed a new cable box or TiVo to actually watch anything in HD. I saw no point suggesting a Blu-ray player (DVDs are plenty) or a mere antenna (no going back once you’ve had a DVR). I figured their brand loyalty would make TiVo the best option, since cable-company DVRs never work as smoothly. I left out BluRay, media computers, and the old-fashioned antenna actual insisted that they needed an HD TiVo. Read the rest of this entry »
