No more bad air!

The fans push the hot air reliably from the case and leave the computer components freely "breathe" again.
No Hitzetot the CPU, the memory or even the Southbridge more.
Even in large enclosures, which are very shallow and do not allow larger fan, two fans of this variety are incl. Two F8 ​​Pro PWM fans at the rear of the PST composite sufficiently to 450 watt Leistungaufnehmende cool reliably with cable extensions devices.
Better it is really only with a water cooling system and a 120mm fans, but this is just in this case, no space.

So when "lesser" performance classes this fan in a quartet with the F8 Pro PWM is perfectly suited to the PC / server / HPC reliable, especially to cool quietly.
According to it is only when it is too hot the CPU or Soutbridge because then turn the fan all together at full capacity and that that is not very loud but clearly audible.
Who but just needs power and does not want a crashing computer, has to live in the moment with them.

Performance-intensive applications one can also move to a later date and then you have enough rest when you need these times.
