Fanless laptop? at least 15''

post #1 of 5
Thread Starter 
I'm looking for a fanless laptop, and having hard time to find it..

What I want is:
- at least 15'' screen, preferably 17''
- cpu doesn't have to be very powerful, any modern i3 will do
- gpu doesn't matter, can be integrated with cpu
- battery life not important

I know there are 13'' fanless tablet hybrids, such as hp spectre 13 x2, but it is too small, and I don't need tablet functionality.
Just same energy efficient cpu, with large radiator inside large 17'' case that runs passively.
I checked some 17'' dells for example, with very low power i3 haswell, but despite being in such large case, they are cooled by really small turbine type of cooler, which makes them loud under load.
Ideas?

The only fanless processors that I'm aware of are Intel Atoms like the newest Bay Trail Atoms (*not counting HTPC mainboards with soldered processors). These processors have TDP <5 watts.
You will be hard pressed to find such a processor in a 17" laptop.

My advice would be to wait a few years. Broadwell (14 nm process) and Sky Lake promise significant power savings compared to Haswell. Perhaps by then some laptop manufacturers will design and build passively cooled 15" and 17" laptops.

And yeah, it is hard to escape the small high RPM turbine fans.

Even low end i3s put out too much power under load. You'll have to look for something with an atom CPU.

A well built 17" would probably be pretty quiet with a fan and i3. Some laptops will stop the fan if they aren't using much power, and replacing the TIM could quiet it down at load.

Either that or get into modifications

At that point you would end up carrying over a couple pounds of copper/aluminum to dissipate the heat

I don't think your going to find anything but a hybrid tablet thats fanless. Laptops with fans run extremely hot, so taking the fan out it will just overheat.
