Cooling fan for Smartphones CPU

  • #1
Is there a cooling fan with a heat sink on the Smartphones CPU - Quadcore processor and above similar to the desktop and Server CPU?

If not, why?. Is it not required?

Thanks & Regards,

Not as far as I know.

No. CPU's for smartphones are typically designed to use much less power, and thus produce far less heat, than the processors on desktops and laptops. The downside is that they also aren't as powerful. A fan would also be loud and have lots of vibration, neither of which you want in a mobile phone.

I think having a cooling fan would dramatically reduce battery life. I remember the early days of camcorders and the constant lens movement trying to keep things in focus would seriously drain the battery so you'd get maybe 40 minutes of video and 2 to 3 hours of battery life. The strategy was to turn it off to preserve battery drain but then you couldn't respond quickly to something you wanted to tape because of slow startup.

No motors, no moving parts, dim displays are the best strategy now.

Is it feasible to fix a small cooling fan in the Smartphone device ?

Since the cooling fan will require the 5V Smartphone battery, this may drain quickly?

You might be able to get power from the micro-usb port but it will drain the battery. Unsafe battery drain could be dangerous as the battery will heat up too. You are asking in a sense for the phone to use its power to cool itself.

Its kind of like using a fan to cool yourself. As you fan more vigorously you get hot from the exertion.

No. Find someone with a broken phone and take it apart.
