Discuss Connecting 2 12v fans in the DIY Electrical Advice area at ElectriciansForums.net
But the fans are connected to a plug on the motherboard, and not to the supply
I have another question.
Would it be okay to twist the + of both fans together and same with - and the plug it into the connector of the motherboard 0.0
yes I know it,
thanks for your reply .
I meant if I could twist + and + of both fans and both - together and connect the twisted + of the fans to the + of the source and same with the -
Do you understand what I mean? I'm sorry if this question is stupid but I'm no electrician.
I'm thankful for all your replys , DPG and Spoon , thanks .
If I connect them in series and we don't care about a limitation, would they both get 6V and spin almost the same speed ? IDK because they have different comsumption (0.2A and 0.29A) or is it not relevant.
I am connecting both fans parallel to the 12v DC source, where usually the standard fan is connected. So imagine just the xbox with 1 fan like i bought it and I just connect another one to the same 12v Plug where first was one
fans in computers are not always driven at full speed, the speed is controlled by the computer either by regulating the voltage or pulsing the voltage on and off at many times per second (pwm).
it measures the temperature of the air inside the case and the cpu, calculates the amount of cooling required and speeds up or slows down the fans to control the temperature as required.
if you believe that things are running to hot, then it is most likely a temperature sensor either dislodged or faulty.
by fitting 2 fans doing the same job, I would expect them to run slower than a single fan as the controller is slowing them down as there is plenty of cooling happening.
are you concerned that it is running to hot?
adapting computers without fully understanding what you are doing can have the opposite effect of what you are trying to achieve.
No , 4 Pin PWM. I thought I said jt before I'm sorry if I forgot to say that.So your fans are 3 wire fans?
