Coolers for Socket 478, Spring/Summer 2002

Part 4. Table of Ranks (technical and economic assessment of the coolers and technical and economic ratings)

For better understanding of the idea we recommend that you first address our new testing technique of assessment of consumer qualities of cooling systems and then turn to the summary table of consumer parameters of the coolers and their ratings. Table 1. Technical and economic parameters of the tested cooling systems

Diagram 5. Consumer chart of the cooling systems

Diagram 6. Efficiency-to-noise

Note
Efficiency-to-noise correlation is calculated the following way:
ENC = DF*(RF_th/TR)/(NL/RF_n),
RF_th - thermal reference factor (thermal resistance θ_ja), TR - thermal resistance θ_ja of a cooling system in question, RF_n - noise reference factor (noise level), NL - noise level of a cooling system in question, DF - dimension factor (equals 10).

Diagram 7. Efficiency-to-cost

Note
The efficiency-to-cost correlation is calculated the following way:
ECC = DF*(RF_th/TR)/(P/RF_c),
RF_th - thermal reference factor (reference thermal resistance θ_ja), TR - thermal resistance θ_ja of a cooling system in question, RF_c - cost reference factor (reference cost), P - average retail price of the cooling system in question, DF - dimension factor (equals 10).

Diagram 8. Functionality-to-cost

Note
Functionality-to-cost correlation is calculated the following way:
FCC = DF*(IAF)/(P/RF_c),
IAF - integrated assessment of functionality of cooling system, RF_c - cost reference factor (reference cost), P - average retail price of a cooling system, DF - dimension factor (equals 0.1).

I think no comments are needed.
