Why don't you try a cpu stress test to meausure the cpu temperature with and without the fan ? I think you should try if you're quite concerned about this.

Hello there,

I have a pico psu (not the offical one), but I don't think they're more efficient. More compact and optimized for space (hello sff pc) ? Yes ! Because your power brick is outside your system.

What do you really need ?
