I've noticed the fans run way to fast with a 12v charger i guess because when there in a pc there controlled by the motherboard

pc fans are 12v and are designed to work with that voltage for many years. there's no problem running them 24/7, you just have to remember to clean them every now and then. if the fan runs way fast then it means its supposed to run in a high RPM by default. dont worry pistolpanda, 12V is the right voltage unless your fans are too loud/powerful and you want them to run slower, but I see that this is not the case here.

UPDATE: I was using an old Gameboy charger from my childhood (cutting up childhood memories to power the growing of an illegal substance... /facepalm) and the fans were running really slow, so I went and took a 120V ---> 12V Super Nintendo power cord and hooked that up. Fans are now cleaned out and running like a dream! They are a little bit loud, a slight hum really, but I'll be able to deal with it. This grow case is supposed to be a server afterall, so I don't think that will be questioned.

Thanks for the help everyone, my heat is under control for now (I think...) and I will update once more with the actual numbers, for now have some old numbers.

Lights on - Cover off: 77F
Lights on - Cover on: 111F
Lights off - Cover off: 68F
Lights off - Cover on: 70F

Humidity varies, but it generally stays from 30-60% so it should be fine.

Pays to run things at their rated voltage, doesn't it?

**pistolpanda** · 01-16-2012, 05:36 PM

UPDATE: It runs at a perfect 86°F. A bit high, but it will have to do, as I've used all available spots for fans (3). I'll post a grow journal once I get my seeds!

Sounds like those fans don't push enough air.

What are their mA ratings?

**paperplanesmoker** · 01-16-2012, 06:25 PM

86 degrees is not that hot, My pc is around 79-85 normally and I have no problems

**electronug** · 01-16-2012, 07:11 PM

It's hot enough...

Don't be lazy! Dial it in!

Best of Luck here Pistol

I am glad that you are getting the problem dialed in. Don't give up. You will be ok with getting this dialed in.

oh i see when i put my fans on 12v they went way to fast for me that's why i am using a 9v charger
