Directions for Heat Sink?

BryanFRitt

Where are the directions for how to use the Heat Sink? I couldn't find any.
How do I use it on the Orange Pi Plus? Do I need to use some sort of 'heat sink silicone compound'? Do I need to cut it?
Does it work? How effective is it on the Orange Pi Plus? Anybody test it?

Hi,

For cooling down orange pi one I use 26x20x40mm heatsink + additional  2mm alu spacers, connected with thermal epoxy glue...



temp. for now are below 40C.. (with openelec) I will check performance with some pi calculations..

about 55°C with a 25x25 fan

Totally weird if you're speaking about an A20 based Orange Pi. You shouldn't be able to exceed 55°C even when the A20 is overclocked and running a 'stress' test: http://www.lemaker.org/forum.php ... 7&fromuid=33332

There's something wrong. Maybe you're measuring instead the temperature of the AXP209 PMU? You can try out the sunxi_tp_temp tool referenced in the thread above. And check the PMU's temperature using:

1. awk '{printf ("%0.1f",$1/1000); }' </sys/devices/platform/sunxi-i2c.0/i2c-0/0-0034/temp1_input

Copy code

For all users of an H3 based Orange Pi: you should become familiar with what let your board overheat and adjust that: http://linux-sunxi.org/Cpufreq

And heatsinks are pretty useless when you're not ensuring airflow. A heatsink in a small enclosure is wasted money.

Using the fan is essential. Heatsink allone wont help much.

here's my temporary solution.

Came back home today and found one of the heatsink sets and the thermal adhesives in the mail. Cleaned the surfaces, attached the heatsink, but still getting CPU3 killed during boot

/sys/class/thermal/thermal_zone0/temp and /sys/class/thermal/thermal_zone1/temp do seem to be 3 or 4°C cooler though, but apparently not enough.

How can I check the CPU temperature? Is it possible?

Thanks.

Depends on the device you're using. And generally speaking: You won't be able to read out "CPU temperature" -- only SoC or PMU.

The A20 contains a touchpad controller which contains a thermal sensor. This piece of hardware is nearly undocumented and even the kernel sources for its driver say regarding the thermal values:

1. * Allwinner does not have any documentation whatsoever for
   
2. * this hardware. Moreover, it is claimed that the sensor
   
3. * is inaccurate and cannot work properly.

Copy code

The H3 has a "Thermal Sensor Controller (TSC) providing over-temperature protection interrupt and over-temperature alarm interrupt" which is read out by a driver being responsible for shutting down CPU cores (one after another) when internal temperatures exceed 70°C. So there's a driver that can both read out these values and act upon.

But this is not "CPU". This is always "SoC" (containing GPU cores and other stuff like a display controller, that also produce heat).

And then there's the PMU/PMIC. On A20 based boards this is always the AXP209 which has an internal thermal sensor that can be read out (more precisely than the A20's touchpad controller). No idea about H3's PMIC. But gaara talked about an A20 based Orange Pi (and most likely not about SoC but PMU instead).

So it is not metal cooler? Just some thing which attaches to CPU?

This Orange Pi 'heat sink' looks more like a 'refrigerator magnet' than a typical 'heat sink'.

@surfer60 has bought the same heatsink.
maybe he can say something about it.

It is just a adhesive tape.
You should use something like this:

I just installed rpi heatsink.
It works good.

Yes, I can say that I just ordered heatsink RPI.

In the ads they call it a 'heat sink' and don't have anything calling it an 'adhesive tape'.(although it does say it has 'single-sided adhesive graphite flakes') Deceptive advertising?

Quotes [with added bolding]
"Orange PI Set 1 : Transparent Case + Sata Cable + Heat Sink + Power Supply. not for banana pi pro and raspberry pi 2"
"0.2mm Mobile The graphite heat sink / CPU thermal conductivity graphite/ single-sided adhesive graphite flakes"

Whatever it is, some directions for how to use it would have been nice. How can one use this?

Сould Somebody  help me with reception of this heat sink, because This shop does not send parcel in my country.
