Question Fan selection

[Joshy5]

I'm shopping for a fan for my wii portable, that needs to be 40x40x7. I have found several blower fans, but the wattage varies greatly.
The lowest is 0.3W, and the highest is 1.6W.

Would the 0.3W fan be less powerful, or just far more efficient?
Will the 1.6W just be less efficient, and/or would the fan be really loud frequently.

There's a 0.6W Sunon too, that's 35x35x7.

Fan selection shouldnt really matter, just get one thats the size you want with an additional beefy heatsink and you should be good, I mean just take a look at the factory cooling solution.

To add to Deku's post, if you're using a PMS then you can use RVLoader to set the fan speed and shave off some unnecessary power usage. Although, the power consumption of the fan isn't going to break the bank battery life wise

Thanks guys. Yeah I've ordered the 4Layer PMS. Doesn't it have fan speed control built in, with the temperature sensor? So will the fan only ramp up to max power if the processors get real hot?

Doesn't make sense to me to set the fan speed lower if that's the case, cause all I'd be doing is restricting the max power right? So if the processors got really hot, then the wii would shut off, rather than use the top end of the fan speed.

A 4 layer Wii's thermals are extremely forgiving. So long as the CPU and GPU IHS have direct thermal contact with the heatsink(s), virtually any airflow will keep the temps well below critical. It's really just a question of how much noise you're willing to tolerate scaled against the mass of the heatsinks. A basic 40x40mm 5v blower fan running on flat 3.3v sending air down a single 40x40mm heatsink that's glued to a 2mm copper plate to sink heat from both chips is more cooling than the G-Boy had, and the Ashida's cooling is overkill purely because the space was there to use.

It's up to you really. Shit's flexible, there isn't a right or wrong answer in this case

EDIT: Actually I should mention that some fans REALLY don't like being run at too low a speed and might make a loud clicking noise and/or die entirely, which can happen when set to automatic. Test first before you set and forget.
