Do We Need Raspberry Pi Heat Sink For Cooling?
Some people believe Raspberry Pi Heat Sink is necessary. But for any normal use you do not need to cool the chips on the PI with heat sink, unless they get much hotter than a 100 degrees Celsius! You can find an example of an absolute maximum temperature for silicon devices for example.
Obviously operating any practical device at such temperature is very often unlikely, and such temperature limits are only practical in very special cases, like deep sea oil drilling installations.
What The Raspberry Pi Guru Says?
Knowledgeable Members of the Raspberry Pi Forum have said heat sink is not needed for the normal operation of the Raspberry Pi device! Some have even stated that you do not need them for any type of operation of the Raspberry Pi.
When you overclock Raspberry Pi (Speed it up), it will generate more heat. But the only reason to we want to cool them isn’t for the speed but life of the chip. Operating under hot temperature for long period of time could cause damage to the chips on the Raspberry Pi.
My View on Raspberry Pi Heat Sink Argument
In my opinion if you are using your Raspberry Pi within the normal use, then YOU DO NOT NEED Heat Sinks for your Pi. However if you use it outside of the “normal” use (like overclocking), it may benefit from heat sinks. A close case with a venting fan would also help as well as the raspberry pi heat sink.
Of course if you just want to dress up your Pi, the heat sinks will not hurt it either. :-) It comes down to the fact that you do not need to waste your money on heat sinks!
I think it’s just some of those old school people who believe in using heat sinks for every chip has when you are/aren’t overclocking.
Raspberry Pi Heat Sinks are about $2.25 to put them on, so it’s totally up to you.
