Demanding microprocessors require highly efficient cooling to prevent loss of performance or even an early 'death' through overheating. PAPST has developed a new fan generation with an edge length of 70 mm and depth of 15 mm especially for new CPUs, such as Intel's P4.
Their particular features: a small hub, large air throughput and high efficiency. The recipe for success of the company's completely newly developed 700F series of fans is as simple as it is effective: in order to master the increasing temperature development of microprocessors, a fan's performance dimensioning must be precisely adapted to be given relationship between the CPU and its heatsink.
This means that not just the ventilating power, but rather the required operational pressure is crucial to efficient cooling.
This series of fans has been developed precisely for these operating conditions. The profile of the fan blades and the interior contour of the housing were designed using computer programs to accurately define the optimum operating point for the typical cooling of CPUs and simultaneously harmonise this operating point with low operating noise. The result is that the 700F series achieves a ventilating power of 44 m3/h and a static pressure of 65 Pa from very compact construction dimensions. These fans are driven by maintenance-free DC motors with electronic commutation and electronic anti-blocking and anti-overload safeguarding. With the PAPST Syntec sleeve bearing system they achieve a lifetime of at lest 60 000 hours.
The fans are supplied as 12 or 14 V versions and, if desired, with a tachosignal for monitoring rotational speeds and an alarm signal for monitoring operation.
