Temperature vs. Reliability

Electronic equipment life is directly related to operating temperature according to the Arrhenius function which predicts that each 18 degree F (10 degree C) increase in operating temperature reduces mean electronic component operating life by 50 percent. Conversely, each 18 degree F (10 degree C) decrease in operating temperature increases mean electronic component life by 100 percent. It is possible to decrease the inside case temperature of many electronic products that much by simply adding a fan or blower, especially if they are not already forced-air cooled. Fans and blowers suitable for use in many types of equipment have become very inexpensive ($5 or so from wholesale suppliers) in recent years, because of their widespread use in computers. Where $5 may double the life of $1000 radio, what are you waiting for? Even if a suitable blower will cost $20, where can you find a better investment? ©2005 Tigertek, Inc. All rights reserved.
