How to use computer fans?

[Th3 sand m4n]

To run PC fans i always just use a computer powersupply... easiest/safest option.

can you use the powersupply to power the fans with out hooking it up to a mother board and the other parts? If so that is what i will be doing because the case came with a power supply.

Ok me and a friend are going to try and set up a lowryder stealth grow in a pc case we have every thing worked out execpt the ventilation. how do i wire up a computer fan to a socket? it has a red cord and a black cord what do i do... i have a general idea but some professional help would be much appreciated lol. Also in the thread i got the idea from the guy says he had a carbonfilter hooke up to the fan any ideas how to do this? thanks for the help and here is a link to the thread (it is Rating: 5

well there seems to be a few ideas here sand man let us know
what ya end up doing
cheers all

sorry for the double post im a lil high lol but ya anyways....

Well first off i was going to just go buy the ones off the website coolerguys but i dont want to pay 20 bucks a piece so i think me and my friend are just going to wire an adapter to it. Also we might take it to radio shack to be safe like a couple of people said lol *we dont want/need dead stoners* idk i will keep you guys updated how it works out ! hell i might even do a grow log because i think this will be interesting :smokin:

Hooking it up in the motherboard?? What the hell, does that computer still have power going to it?? I hope not, and if so whY?

doesn't make much sense to run a 250-400 watt computer power supply to run a 10 watt computer fan ... $$$ ... :smokin:

I have 10 pc fans running in my indoor. All of them wired with 3 AC-DC 12V transformers (each one cost me 3â?¬). Each transformer has polarity selection button and voltage output regulable (from 3 to 12V). Wiring in very simple.

I have 4 8cm fans conected to a transformer (it gives 1,2A, and each fan uses 0,2A). Works with lights, to cool them.

Another 3 to other 1,2A transformer (one 12cm fan running at 0,4A and two 8cm running at 0,19A). They work 24/7.

And other 3 running with lighs on, 2 12cm and 1 8cm. This transformer become very hot, because the load is similar to the output. I would prefer to use a 1,5A transformer, but i was unable to find it cheap.

DC fans RPM (=noise and air flow) are easily dimmable, selecting the output V. Aditionally, i have a regulable bay for computers wich can regulate the speed of 4 fans (i have it near the thermohygrometer, so i adjust fans speed according to temp and humidity, specially the one i use as humidifier). I bought the 2 packs of 4 thermaltake fans (2 12cm and 2 8cm) with the regulating bay for 20â?¬ in a local computer store.

it wasnt a computer its just a case that came with a powersupply. once again i was high and wrote some stupid shit. my question i guess is how do you connect a powersupply to the fan and get it to work with out hooking up the other computer parts.

If its a ATX power supply, it dont work without motherboard. You must make a bridge to do it work. It inst difficult, but no i dont remember exactly how to do it.

In the other hand, use a 250w (or 400w) power supply to run fans with low power is a waste, and with so little load, the supply voltage can be quite inestable. It would be a great idea to use it to power all the setup (using 12V CFL and leds, and the fans).
