This is our Antarctic cooling system for PCs that consists of 2-5 ball bearing fans (depending on the case you choose) plus we add a digital controller to adjust the fan speeds that has 4 temperature sensors that we install all over the case to monitor HD, CPU, VGA and System temperatures.

This system automatically adjusts the speeds in accordance with the temperature information that is received through the 4 hardware sensors. Currently we use the Mcubed high quality BigNG controllers with the sensors on CPU, VGA, HD and ambient. All the temperature limits are preset during stress testing for the safe noise to heat ratio.

Additionally, where space/configuration permits, we do custom modifications and replace all or some of:
 -  The motherboard's chipset heatsink+fans with more powerfull ones that will ensure quieter operation over the integrated ones.
 - The VGA heatsink/fan with either Arctic cooling VGA silencers, Zalman copper heatsinks
 - Add HD Cooling where possible such as Zalman or Revoltek HD Coolers.
 - Cut an additional one or two 120mm Fan Hole in the case with silent case fans fitted

This work can take upto a day and is carefully designed and implemented depending on PC configuration (Case/motherboard/VGA design)

In a rare few instances, we may not be able to physically fit any more aftermarket cooling into a configuration. This may be due to the lay-out of a case, or because the stock VGA or hard drive cooling is already very good case and cannot be improved on. If this does occur, you will be notified and we will instead install a premium cooling package, refunding the difference to the card used in the original order.
