6. Compatible CPUs
1) Intel Pentium 4 - Socket 775/478
All CPUs conforming to Socket 775/478 platform
Cautions)
① No components higher than 39mm (possible examples : PSU, graphics
card, RAM etc.) should be present within a 68mm radius from the center
of the CPU.
② For Socket 478, as shown in Figure 2, a motherboard that is not compliant
with the "10.2mm Motherboard component height restriction" standard,
introduced by Intel, may create interference between components and the grip of CNPS7700. Please do not
install the CNPS7700 if this interference is observed.
③ For more information, please visit the Zalman website (http://www.zalman.co.kr) and click on the links of
"CNPS7700 Compatible Socket 775 Motherboards List" and "Compatibility between CNPS7700 and
Socket 478 Pentium 4 Motherboards".
Notes)
3.4GHz Northwood, Prescott-478 of 2.8A/E GHz or higher, and Prescott-775 of up to model 560 dissipate
an exorbitant amount of heat (84W ~ 115W). Refer to the table below and adjust the fan speed so that the
CPU-Case temperature (T
C) is lower than the maximum CPU-Case temperature (T C_MAX ) .
※ Hardware monitoring programs report CPU-Die temperature (T D )
as the CPU temperature. CPU-Die temperature (T
D ) is measured
about 4 ~ 10
℃ higher than CPU-Case temperature (T C ) depending
on the motherboard and/or BIOS.
Refer to the Zalman website for more information.
2) AMD Sempron / AMD64 - Socket 754/939/940
All CPUs conforming to Socket 754/939/940 platform
Cautions )
① No components higher than 39mm (possible examples: PSU,
graphics card, RAM etc.) should be present within a 68mm
radius from the center of the CPU.
② For more information, please visit the Zalman website
(http://www.zalman.co.kr) and refer to “CNPS7700 Compatible Socket
754/939/940 Motherboards List”
