New HTPC: A6-3500, Wesena ITX7 build

There would be at least some dissipation effect from the chassis being a better conductor of heat than steel is.

For example, it's very well established that the aluminum enclosures in Apple products (which, as we know, you will never own) directly contribute to them being able to use quieter smaller fans in their computers, even though the enclosure is not actually designed as a direct contact heat-sink with the components.

My quad core i7 iMac gets quite toasty when doing huge encode batch jobs in handbrake, to the point that it's hot to the touch, even though the fans are barely idling. That's not hot air "trapped inside" the chassis, that's the aluminum dissipating the heat from inside of the chassis to the cooler outside air.

I agreed that certain metal absorb and dissipate heat better than another, but I don't see how the case can act as heat sink. I don't see the correlation here. The heat you feel on the case is generated by the hot air traps inside the case. If they build the case with proper exhaust ports and exhaust fan, very little heat will trap inside the case. Or if you leave one side of the case cover open to allow hot air out, you should not feel the heat on the case cover at the other side.

If the the case does not act as an heat sink, than it is useless to use the case as cooler. one might just doesnt use any hsf at all.

the question is, can one does not use any cooler to use the processor?

maybe the owner could try open the case and try abuse the processor. if the case heatsink is hot, then it proves that the case is hot not because of the trapped hot air. well, not scientifically, but a good indication as to what actually happens.

I tried it on 2 PC's with the cover open. The case felt warm when the cover is closed, and when it is opened the case didn't feel warm. With cover off, the PC ran cooler too.

If you want a case that is built with heatsink, you have to get a case in the links below. It's designed and built with heat pipes connects to the case shell.

Fanless Cases

Belanus and others on this thread maybe interested in a similar but fanless build by politby on avsforum using the streacom fc8 (aka itx8):

Politby also did his build with an SSD and his boot up is ~30 seconds to XBMC.

you should tell people that you did test it with 2 cases before.

thanks for the info. appreciate it.

He mentioned Origenae M10, and it is one of my favorite case. He should have built his HTPC with it. I mentioned it here- Origenae M10.

Looks good sir! Very snappy, especially looking at it with my ATV2 eyes. Time to build methinks =)

how can the two case that you mention any better than the fanless wesena? afaik, the wesena case is also "designed and built with heat pipes connects to the case shell".
