I have an Asus P5W DH-Deluxe mobo.
It has the following fan headers:
1 - "4-pin" fan header - using to control the CPU fan.
4 - "3-pin" fan headers
I have a NORCO rackmount case that has the following fan configuration:
- 2 x 120mm front fans
- 2 x 80 mm top fans
- 2 x 60mm rear fans (optional and not currently installed)
All the fans have the 4-pin molex connectors, and the mobo has the male ATX 3-pin headers. Obviously I would need adapters to connect them.
1. Assuming noise is not a factor, what are your suggestions for an optimal setup?
2. Does the fact that all the fans only have 4-pin molex connectors indicate in any way that I should only be plugging them into the power supply instead of on the mobo headers (using adapters of course)?
3. If I plug all the fans directly into the power supply I assume they will always be powered on, but is there a problem with that? (see question 4)
4. Does the mobo require any fans be connected to it?
5. What are the pros/cons of installing the rear fans (in addition to, or instead of the top fans)? If in addition to the front and top, there would be 6 fans total with only 4 available mobo headers. Any way to split onto one header (is this recommended and if not, then what is recommended way to plug all 6 fans in?)
Thanks for you help.
