Smarja, tak si to precti. Potom to samozrejme zkousel i s vetrakem.

Abych ti ulehcil hledani: "Now we get to the hard part: How to achieve passive cooling. Well almost anyway. The whole setup is a negative pressure case. There is somewhat of a vacuum being created inside this Lanboy by the PSU output fan and the output of the lower case fan (the subject of part three in this series). All the vent holes, the drives, the ports, and every other possible air-entry hole has been sealed. So the only way air enters the case is through the Alpha duct. This allows enough airflow to cool the P4 2.66 very well, without the duct fan even running. Using the A-Open SilentTek utility, the duct fan never turns on till the CPU temp reaches 39C, which is rare for me. Even with ambient temps around 27/28C, about the only way the duct fan turns on, is to run CPUBurn."
