Arctic Cooling "Alpine 7" Aluminum CPU Cooler, for Intel LGA 775
Arctic Cooling "Alpine 7" Aluminum CPU Cooler, for Intel LGA 775.
Features:
Extremely Quiet by Patented Fan Casing:
The low speed 92 mm fan reduces the noise level to a minimum.
The patented fan holder is able to practically eliminate the typical buzzing sound of 92 mm fans.
The PWM chip in the motor allows an exact fan speed control over the BIOS. (4 wire).
The Fluid Dynamic Bearing keeps oil inside the bearing and thus reduce friction inbetween and keep the noise level to a minimum.
Integrated Cooling of Voltage Converters:
Air is drawn in from the top.
Some air is blown out to all four directions in order to cool the voltage converters and chipset.
Patented Vibration Absorption:
The four rubber connectors on the fan case act as a vibration damper to absorb the vibration of the running fan and prevent vibration transfer to the heatsink and the case.
Easy Installation:
The cooler is to install within seconds.
Long Lifetime / 6 Years Warranty:
The Fluid Dynamic Bearing offers a unique 400'000 h MTTF at 40oC. Therefore we grant a unique 6 years warranty.

Notes:
Noise Level:
The noise level is measured in Sone (loudness) instead of dB (sound intensity).
The loudness depends upon ears response curves and tells you exactly, how bothering a certain noise is.
Cooling Performance:
All Pentium 4 CPUs have an integrated "Thermal Throttling" i.e. in case of overheating risk, the number of working cycles is reduced, thus lowering performance however preventing the CPU from over heating.
Therefore to reduce the noise level, a Pentium 4 CPU cooler can work at its limit and this way drop the noise level significantly.
The Thermal Throttling get usually activated at 85oC core temperature.
Good system ventilation is crutial for the CPU cooling. The temperature in the area of the CPU cooler should never exceed 38oC. Therefore we recommend to use a temperature controlled Case Fan.
Thermal Compound:
We ship our coolers with the ARCTIC MX-1 thermal compound. This compound hardens during the first 200h while the performance improves steadily. With heating up the paste / heatsink the process can be shortened. The performance is even from the beginning good enough to cool your CPU reliable.
