The Intel Pentium processor is currently a very popular choice of CPU since it offers excellent performance and reliability. Traditionally, Intel processors have always run cooler than equivalent offerings from their rival AMD. However, more recently there has not been much difference between them in terms of thermal output, as the Pentium D CPUs now run hotter than their AMD X2 counterparts! This means that providing safe and quiet cooling is more of a challenge.

However, CPU cooler technology has not stood still, and now we are delighted to be able to offer several new products which are specifically designed to give excellent cooling for Intel processors in near-silence. If your current cooler is driving you nuts, or if you just want to build a PC right in the first place, these products should be number one on your shopping list! Forget other “great pretenders” - if you want an extremely quiet system, these are the coolers to use.

ZALMAN CNPS9500AT Copper Heatsink and Fan Socket 775


Specifically designed for Intel Socket 775 and easy to install withUltra-quiet PWM fan for automatic fan speed control based on CPU temperature. Compatible with Intel Dual Core Pentium, Pentium 4 and Celeron D for Socket 775

The CNPS9500-AT is only compatible with Pentium LAG775 systems. This is because the AT is supplied with a PWM fan. A PWM fan is designed to increase and decrease its RPM depending on the temperature of the CPU and BIOS settings.The primary innovation lies in the patented ‘figure of 8’ shape bending of the heatpipes. This produces the effect of up to six heatpipes when in actual fact there are only three. The excellent cooling performance and efficiency of the CNPS9500-AT is achieved by the aerodynamically designed ultra-slim heatsink fins and their performance optimised layout. This layout reduces airflow resistance and minimises the weight of the cooler.

Retails for approx £18-19 This cooler is brand new onto the market and as Xilence is a newcomer into the cooling side of manufacturing it has not yet been given the full recogniction it derserves. This product i would fully reccommend to go against in fact beat the performance and noise levels of the popular Arctic Freezer 7 PRO. Slightly dearer however well worth the couple of extra quid.

Arctic Freezer 7 pro socket 775

Arctic-Cooling presents with the Freezer 7 Pro the optimum solution for cooling Intel LGA 775 processors. Heat pipe technology, which has already proven its worth so far, makes it possible for the cooler to absorb the heat generated by the processor in an optimal way. 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.Powerful cooling 6 Heat Pipes (three used double sided) are able to transfer heat up to 200 Watt. The heat exchanger is built of 42 fins and consists of a surface area of over 4700 cm2 and allows for resistance free energy transfer to air.Air is drawn in from the side of the fan to cool the components around the CPU.
Some air is blown out towards the voltage converters o­n the mainboard with the bent fins at the bottom.

Technical data:
Bearing type: ceramic bearing
Weight: 520 g
Service lifetime: approximately 137,000 hours
Operating voltage: 12 V DC
Rotational speed: ~ 300 - 2500 RPM/min. (controlled via the PWM signal of LGA 775 mainboards)
Air flow rate: maximum 45 CFM = 77 m³/h
Noise development: 0.9 Sone
Connection: 4-pin (PWM)
Suitable for: all Intel Pentium 4 and Pentium D processors for sockets LGA 775

Retails for approx £15.00 The Freezer 7 Pro is an excellent replacement for the stock OEM cooler and also for those that are running loud aftermarket coolers as well. Conquering the heat produced by Intel processors today can be a difficult job but Arctic Cooling has subduing the heat problems. With the uniqueness of the heatsink and the fan assembly this cooler will look good in anybodies case. Lastly, this is a larger heatsink than some, but honestly I don't think it should be a problem mounting this on any motherboard because the mounting brackets makes the bulk of the cooler sit much higher than anything on the motherboard. So if you are in the market for a cooler that runs ultra quiet and performance pretty well, the Freezer 7 Pro maybe a good start.

Arctic-Cooling Alpine 7 CPU Cooler 775

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. 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.The body of the heatsink consists of 27 tapered aluminum fins spaced 2~3 mm apart. The heatsink is oblong in shape, and the diameter of the fan is wider than the heatsink, allowing some air to be blown down the outside edge. This ensures that a small amount of air flows around all four sides of the heatsink, providing cooling for the VRMs on the motherboard.The Alpine is exactly as Arctic Cooling describes it:

Heat Sink: 78 x 98 x 56 mm
- Fan: 113 x 101 x 47.2 mm
- Overall Dimensions: 113 x 101 x 91.7 mm
