best cooling solution

Mon Aug 05, 2013 11:36 am

Hi,
didnt think I will need one, but lately (since openelec 3) I started using my Rpi more offten. My transparent case is geting warmer and warmer question is which one should I buy. Case was bought from RS together with RPi and I want something that can fit in. As much as I can remember there was something like 3 in 1 heatsink kit for RPi. Thanks.
4 months for 256MB RPi ...
maybe 8 months for 128MB RPi who knows...
Thanks RS.

unless it is shutting down due to heat you don't need one
or if you do than this is the best one

I noticed yesterday after almost 12 hours my pi restarts few times and case is very hot so I think I need some heatsink, this case is not solution for me since I dont plan to by camera and I already have case from RS.

cat /sys/class/thermal/thermal_zone0/temp /sys/devices/system/cpu/cpu0/cpufreq/scaling_cur_freq
which case ?
are you using a USB wireless adapter plugged directly into the RPi?

you don't need to use a camera with that case ;-p
though it's not ready yet.

or you may want to buy some RAm heatsinks like

I use these - primarily as OTT protection as a RPi in the sky won't sustain a reboot. These just 'glue' onto the 3 key chip with heatsink tape - they fit fine within PiBows and other standard cases.

I would check to be certain it is overheating, you can check with:

Code: Select all

/opt/vc/bin/vcgencmd measure_temp
It will only shutdown at 85 degC.

I somewhat doubt it is overheating, these type of SoC are designed to dissipate heat naturally and run at high temperatures since they are used in smartphones where forced air and passive cooling isn't really feasible.

Unless its rebooting or freezing on you then you should be fine. If you can remove the top piece of your case I would advise to do so. Its less protected but the heat is allowed to escape and more cooler air will help it cool better.

Even before the heat will be a problem your more likely hit power supply problem i.e not providing a stable 4.9-5.1 vs (or something like that) that it needs. So yeah remove the top of the case. Or if you something like I have you can remove the side piece, either way just let it breathe better. and don't spend more money on it.

Cooling is something you actually need when you overclock your raspberry or when it will operate in high temperatures. The following article describes a way of overclocking and cooling the raspberry Pi.

Thank you.

Thank you.
you made a typo!
your "or" should be "and"

If you overclock and operate the PI in a hot environment, only then it will make any sense to try to cool the PI, but only passively (small heatsink) and only on the SoC. Overclocking has no effect on the LAN9512, and all that it does is making it more unlikely that the PI will shuttle back the overclocking when it becomes hotter than 85 degrees Celcius.

other measures are not financially sound, as even in extreme cases the PI will only last a half year shorter than its expected lifespan, (estimated at at least ten years).
