The OD1238 VA Series (120x38mm) offers airflows from 3.96 to 8.0 m3/min (140 to 283 cfm). The OD9238 VA Series … [Read more...]
Lowering a Notebook CPU Temperature Using a Dual-Tunnel Blower
Figure 1. Side by side comparison of blower technologies. Introduction Notebook computers on the market today may be classified in three categories. In the first category are the super slim and powerful notebooks such as the ThinkPad X300. In the second are the slim and light netbooks such as the ASUS Eee PC, and in the third are the high-end mobile workstations for … [Read more...]
Health Assessment and Prognostics of Electronic Products: An Alternative to Traditional Reliability Prediction Methods
Introduction Traditional handbook-based reliability prediction methods for electronic products include Mil-Hdbk-217, Telcordia SR-332 (formerly Bellcore), PRISM, FIDES, CNET/RDF (European), and the Chinese GJB-299. These methods rely on analysis of failure data collected from the field and assume that the components of a system have inherent constant failure rates that are … [Read more...]
