as regards the above welcome.
and you conclude that you still need to...jamesh wrote:You don't need a heatsink or fan. Remember these chips are designed to go inside phones etc where there is no fan or heatsink available, so they have to run cool.

Can you log the temperature data without the fan while compiling something for 30 minutes and then do the same log again with the fan and see at what temperature your pi fails (if it fails due to overheating). This will also show whether it made any difference to the temperature. This sounds like there's a bigger issue causing your pi to fail.AAShepAA wrote:Sorry guys, but the comments that the Pi doen't need cooling are wrong!
Let me preface by saying - perhaps under normal circumstances you are corrects but mine had needed it from day one. I spend at least 2 weeks trying to figure out why mine would lock up and shut down. I bought the best (recommended) power supply I could fine and it would still die. And this was all without it even in a case (if which I have 2 nice one laying around).
As a last resort - I took an old table-top fan that I had laying around and put it next to the Pi - guess what? It never dies!
I agree that it shouldn't even under normal circumstances here in Arizona, but it does. So, perhaps instead of, "You don't need to cool it." We could give the guy some suggestions.
Almost certainly a fault on the board. You should be able to run the SoC at full tilt for ever and it shouldn't get so hot that it hurts. A trace of the temps woudl be useful.Respectech wrote:Like another reader on this post, I also have a Pi (my 2nd RPi, a 512MB model) that overheats and locks up. Of course, I am running several scripts on it that are placing it at 100% CPU utilization for long periods, and I have it overclocked to 800MHz.
I had an old aluminum northbridge heat sink which I cut to size and placed on the SoC. During these intense processing periods, it gets hot enough to hurt to the touch, but locks up less frequently than without. If I blow a fan across the heat sink or place the Pi on an ice pack (with an insulator, of course), it doesn't lock up at all, even under non-stop 100% CPU utilization.
I have recently started logging the temperature and will find out at what temperature it tends to lock up. When I do, I'll report back here.
Another shipment of three Pi's just showed up today, so I'll be testing these as well.
Yes, your contract of sale is with the people you bought it from, so they are the people you need to talk to.Respectech wrote:If this doesn't happen on the other Pi's I have just received, what is the procedure for doing a warranty return. Do I contact Element14 (the vendor I purchased from)?
You could try a simple fan (desk fan!) blowing over the device to keep it cool. If that makes the problem go away, then you probably have faulty device (they should never fail due to temperature). Are you overclocking - turn that off and see if the problem still occurs.Buda wrote:Ok, iam having a cooling problem, my raspibmc slows down @ 142F (61.1C) after an hours worth of a movie, locks up @ 145F (62.7C). Room temp is 76F (24.4C) not sure about the humidity levels, but it's winter here if that gives you any idea. It seems heat related but I'm not sure, what can I do to check it farther?
