AC4G Intel P4 Specifications Copper Base Heatsink

Technology Unique, patent-pending thermo-electric cooling for PC processors. Microprocessor-controlled in PCI form factor.


Thermal load INTEL P4
Maximum Thermal Power 59.8 W 61.5 W 81.8 W
SiSoft Sandra CPU Benchmark 32°C 33°C 45°C
CPU Burn In 32°C 33°C 39°C
Intelmaxpower75% 33°C 34°C 46°C
Typical* 30°C 31°C 29°C
* Typical indicates how the CPU performs under typical stress of Windows applications (Office package and other more intense applications).
All tests were performed at room temperature of 25C. Indicated software was run for 20 minutes to create thermal load. Temperature for all Intel P4 processors was measured with Intel Active Monitor software. A ThermalTake XaserII case with front and rear 80x80x25 case fans was used in all tests. Test results may vary depending on case design and air flow.
Noise level, CPU fan 29 - 45 dBA, dependent on load, <29 dBA in typical operation, dynamically controlled by microprocessor; patent-pending noise reduction technology
Noise level, case fans 3-step microprocessor-controlled: 6, 8, 12 VDC, control according to PC ambient temperature and CPU load, smart noise-reduction algorithms
