CF-28 Overheating?

We have a CF-28 that when used for lots of streaming video tends to get hot and freeze-up.

Two of the lights near the touchpad, the most left and the third one in, flash - meaning that the CF-28 has to be power-cycled.

It has been doing this across many versions of Linux for many weeks now.

I keep hoping that a newer video driver in one of the newer releases will resolve this but am wondering if the CF-28 is simply not able to handle a lot of streaming video.

WDYT?

 

It's not, video streaming was not what the engineers had in mind when they designed it, quality wise but I don't see how It would cause over heating anymore than watching a DVD would. What are the enviromental conditions when it does this?

 

If you mean the room temp, it can get up into the high 80's, e.g. just now it was 88.5F and 37% humidity.

I did stuff a small laptop cooler under it but I wonder if the 5v draw generates as much heat as the fan dissipates?

Also, there is a pcmcia-to-dual USB 2.0 adapter and a pcmcia-wifi adapter in the two pcmcia slots.

I have a mouse and the fan plugged in the pcmcia-to-usb adapter.

There is a place to inject 5v into the dual-usb adapter, would that help with this problem by reducing the 5v current draw through the pcmcia?

 

The PCMCIA card will generate heat... That will travel to the inside. If you are close to 90 deg anyway... Have you read the exact temp where it needs to be rebooted?

 

maybe you need to change the color.

 

I have not read the actual temp at which it freezes, I just put the temp/humidity device out there briefly today to see what was happening. I will tell you that when our son hollers that the laptop has frozen again I can feel the heat in the bottom right corner.

You mean the laptop "cooler"? I am hoping I don't need it at all. Perhaps I really need to get more cooling into that room here in the deep South of the USA it is HOT these days!

 

No... What I was talking about is software that you install that monitors HD and CPU temps.... What are those temps when it reboots? That might help.

You don't want to have ANYTHING with a motor in it plugged into that USB adaptor; it provides 5V out to the ports with a 3.3V->5V step-up inverter. The problem there is that a PCMCIA slot can ONLY provide a total of 400ma at 3.3V; trying to feed 2 5V USB ports rated at 500ma each from that source as well as the USB card itself is just asking for trouble. I'm certain it is why our forum members have reported such a high failure rate with these cards.

An external drive with its own power pack or even a couple of thumb drives should be fine; but I wouldn't load it any more than that. I know you have that external 5V in port on the card; I've found it does NOT work very well.

When these cards overheat or fail due to that current overload they can cause corruption of the USB driver stack and even completely crash the machine.
