Pc Case Fan Question

[abu_has_the_power]

i have 3 case fans linked together and hooked up to 1 power molex directly. now, does that mean all my fans are running as fast as they can? they are linked together and connected directly to 1 psu molex. r they running at full speed?

[ilw]

if its with standard splitters (ie hte ones that came with the fans) then yes, all the connections are in parallel so they each get full voltage, and if your power supply can handle it full current --> full power/speed

but it's hardly pushing air at all?!?! i put my hand next to the one on the side, and i can hardly feel any air movement

i have 80 mm btw. are these supposed to be like this?

are they faster when you plug them in indivdually to your case fan connector on your motherboarD? you should atleast have the cpu fan, and one case fan connector.

What kind of fans are they? Model number? (There are some fans that are really slow and quiet.)

Did you hook them up in parallel or serial?

they raidmax ball bearing fans. not sure bout model #, but it looks like every other 80 mm case fan. the led one is the one i put my hand to the most, cuz it closest, and it's not pushing out all the air i'm expecting it to.

[abu_has_the_power]

oh, yea. all the temp monitor software i use say there's 2 more fans that display no #s. i'm guessing the fans arn't connected to the mobo, but how do u connect them? i don't c any parts on the mobo that can receive the molex plug?!?! and the 3 fans are parallel. all connected together, using 1 psu molex to plug into the psu.

[Virtualbody1234]

You can only use speed monitoring if the fan has a third wire like the yellow one in this pic:

The red and black can be left connected to the powersupply and the yellow goes to the motherboard fan connector.

[abu_has_the_power]

oh, ok

[abu_has_the_power]

does the 80 mm push a lot of air, cuz mine don't

[abu_has_the_power]

and also, i'm trying to add either a 120 mm or 90 mm case fan onto the heatsink of my gforce fx 5200. how do i do that?

[abu_has_the_power]

help with above question please?

The fans could be fighting with each other when the flow of air is in opposite directions.
