1. [Amps] Forced-air cooling system measurements (score: 1): Author: Scott Townley <nx7u@cox.net>; Date: Sun, 12 Sep 2010 13:25:26 -0700; The general recommendation for checking forced-air cooling system performance is to use a manometer to check back pressure. I wonder, isn't the "true" test the CFM in the exhaust? After all, if the b; /archives//html/Amps/2010-09/msg00130.html (7,672 bytes)

Re: [Amps] Forced-air cooling system measurements (score: 1): Author: Ron Youvan <ka4inm@tampabay.rr.com>; Date: Sun, 12 Sep 2010 20:33:29 +0000; What you say is true, but the airflow across the heat sink of the heat source with a manometer is the established way to measure the cooling air flow. Using the manometer requires proper ducting and; /archives//html/Amps/2010-09/msg00131.html (7,984 bytes)

Re: [Amps] Forced-air cooling system measurements (score: 1): Author: Roger <sub1@rogerhalstead.com>; Date: Mon, 13 Sep 2010 00:17:10 -0400; IF you have the required pressure drop across the tube you WILL have the required flow. The dynamics are much the same as ohms law. IF you have the pressure (voltage) across a resistor (tube) you wil; /archives//html/Amps/2010-09/msg00135.html (8,761 bytes)
