Computer with no Cooling Fans

at 5:30 am. Filed under Complex Hacks, Computer Hacks, Insane Equipment, What Were They Thinking

 

When I shut down my computers in my workroom there is an strange silence. It’s nice but feels strange since there is usually the whir of computer fans in the background. I have often though it would be nice to locate the computers remotely and simply have a monitor, keyboard and mouse in the room for each system. This passive cooling idea is interesting but you will never see this in an inexpensive off the shelf system since it would increase the cost  tremendously. A small heat sink with a high speed fan is a much lighter and cheaper method of removing the heat from our modern heat producing systems.

"When designing passive cooling, first thing you have to have is lots of surface area to dissipate the heat that a modern computer produces. The second thing to take into account is the airflow. Without fans, the airflow rests solely on convection that is a very low force. This means that the places the air must go, must be open, and clear of obstacles. Convection means that hot air goes up. This would suggest that the heatsinks are lined vertically. This in turn, suggests that the case be modeled like a tower."

    How about an additional ion cooler:

    I built a silent PC a while ago (see website)
    All I need now is a silent monitor (mine squeals like a hungry mosquito)

    Asus A8N-VM CSM motherboards tend to over volt the processor, so results could be even better with better motherboard.

    [...] This computer uses 100% passive cooling (read: no fans or liquid chilling systems). So how is that possible? Well just look at the thing. It’s like one big freakin’ heat sink. We don’t have much information on the design, but from what we can tell, copper tubing helps dissipate the heat from hot spots like the processor to the outer casing. Don’t get us wrong, we’ll take a low wattage fan if it keeps our system running properly. But as a feat of design and engineering, this system is pretty…uhh…well we we’re gonna say “hot” but that doesn’t work in this case. A few more shots: Standing up, it looks kind of like a Mac Pro but cooler. That last pun was originally unintentional, but we’re leaving it all the same. [Hacked Gadgets] [...]
