question about fan power adapter

[yellowbellied]

I plugged a 120 antec computer fan into the 12v ac adapter. It barely powers on the fan. Do you know if these fans just aren't compatible with the adapter?

You would need to look at the spec of the fan, though typically 12V adapters can power up almost any fan. Try spinning the fan with your finger and seeing if that works, if so then the inrush current of the adapter isn't enough to get your fan going and you would need an adapter with a higher inrush mA.

Some of those 120mm computer fans barely blow at full power. They are made to be quiet... You probably want a CPU fan if yopu want to move some air

I bought the adapter from rapid. Yes I Have to help the fan spin up, so it is kinda annoying. Do you have another adapter that will provide a bit more juice to the fan? The antic 120mm fan I,m trying to run zips in my computer, but barely spins right now.

Look at the sticker on the fan's center...12v and X.X Amps? Match those specs and your fan will spin correctly.

I found an adapter that has 12v dc output and 2amps. So if my antec requires only .16 amps, I can hook more than one?

What mA is the 12V adapter you have now? We got a more powerful adapter about a month ago, so if you have an old one then this one would probably work a lot better.

Yea the adapter is from about 2 months ago. Another question. If I run two fans, should I run it in parallel or series?

[Rapid LED]

I believe fans are usually run in parallel

[DrewPalmer04]

two 6v fans in parallel = 12v

Does anyone know how many volts is a computer fan?
