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.

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*(RFth/TR)/(NL/RFn),
RFth - thermal reference factor (thermal resistance θja),
TR - thermal resistance θja of a cooling system in question,
RFn - 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*(RFth/TR)/(P/RFc),
RFth - thermal reference factor (reference thermal resistance
θja), TR - thermal resistance θja of a cooling system
in question, RFc - 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/RFc),
IAF - integrated assessment of functionality of cooling system, RFc
- cost reference factor (reference cost), P - average retail price of a
cooling system, DF - dimension factor (equals 0.1).
