need help on case fans

[john_antonio]

I need help..I currently have 1 Scythe Ultra kaze and a EVGA 650i ultra a1 motherboard.. I'm thinking of getting one more ultra kaze cause my case which is ULTRA E-torque has 2 120mm fan slots but my motherboard only has 1 CHASSIS FAN slot (i think)..i saw something labeled SYSTEM fan..

what is the difference between the two?

if the other fan's cable won't reach the slot in the motherboard, how can i power it up?

and also, what assembly pattern should the fans be?intake outake thing?

thanks!

Front and side= intake

Rear and top = exhaust.

Use a 4 pin 12v molex to power the fan if needed. If you plug a case fan into a MB header, the fan will show up in BIOS as a 'system' fan or whatever the MB header designates the connector as. Antec Tri power fans have a 3 position speed control built in and can be run with speed control from a 4 pin molex connector.

I agree, I have nothing to add except this link.

More links to answer your last question

3 pin to 4 pin with rpm sensor
4 pin Molex pass-through to 3pin power adapter cable

The TX650 isn't even an issue. Good PSU by the way.

.6A might be a little hard on the mobo, but I think they have beefed up the current delivery to the fans on the newer mobos. Odd that the spec. for that is missing from all mobo manufacturers.

how do i use the adapters?do i need to use both the molex connectors?

You plug the adapter into the Molex and plug the 3 pin fan into the adapter. The only adapter that has 2 Molex connectors is a pass through. One Molex is male and one is female. Use it if you are short on Molex connectors. The female side can still be used to power other things.

 

[john_antonio]

there are 4 things in the adapter..so 2 are: male and female molex..and then 2 are 3 pin: one is like the 3-pin with slots and the other is 3-pin with the pins...so how do i use them?

Are you talking about this image? If so that the heck are you talking about?

Here's the deal, no matter what adapter you are talking about. Find the Molex on the adapter that fits into the Molex on the PSU and plug it in. Next find the plug on the adapter that the 3 pin fan plug fits into and plug the Fan into the adapter. Leave all other unused plugs alone.

DONE.

It's virtually idiot proof, you are making a mountain out of a mole hill, just plug it in and be done with it.

All PSUs have 4 pin molex connectors.
