Arctic Cooling Alpine 7 Pro CPU Cooler, 92mm PWM Fan, for Intel Socket 775 CPUs up to 90 Watts
Due to the highly efficient thermal design and PWM function, with which the BIOS controls the fan speed of the Alpine, performs significantly quieter than the standard boxed cooler.
Fan Speed: 500 - 2000 RPM controlled by PWM signal
Air Flow: 36.7 CFM / 62.2 m3/h
Bearing: Fluid Dynamic Bearing

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 our latest ARCTIC MX-2 thermal compound pre-applied. MX-2 is a high thermal conductivity and low thermal resistance compound that optimizes thermal dissipation. It is ideally suited for use in CPU and GPU cooling where thermal conductivity is a major factor.
