I'm genuinely exhausted. I think i've pretty much read everything from start to finish in this thread. But i'm overwhelmed.
I'm not even sure what is on or off topic any more and if I'm even worthy of posting in this thread. But just in case!....
Obviously the more I read the more I keep changing my mind. But I think I'm going to settle of a fully scalable solution. KISS style
Now lets assume a classic CPU cooler, 3070AB and mean well CC (or ebay bargain if i'm being really cheap) 700mA driver powered from a 240VAC (UK) source.
What is the best way to power the fan?, but still keeping it all scalable and individual? DC-DC buck step down from the output of the mean well driver, or an AC-DC converter from 240VAC source? Assuming that I'd want to power the fans at or around 5/6vDC. Considering running them 700mA isn't going to require much cooling, righty? I mean even better would be individually controllable through 5-12v. What's efficient here? What should I be looking at? (My head hurts from data sheets and websites).
I'm basically planning on making one, working with what i've got, and then scale up from there, and move these individual units around to which ever tent/area needs them. I'm hoping this will make them efficient in terms of use, and as i said ultimately scalable, and things should only get cheaper over time.
Proof is in the pudding, but once i crack one, i'll just go ahead and scale up and tbh, if it works, i know for a fact my friends will be asking too, and whatever makes offering them a solution easier for me is good in my books too.
Sorry if i've taken this off topic, ignore if so, and get ready for many more thoroughly confused posts in the near future i'm sure! Sorrrrry!
