NewbQuestion on Case Fans and Slots on Motherboard
Well, I'm finally getting a decent case and power supply. Included with the case are 3 fans (side, rear, front). The problem is on my mobo there is only 1 input thing for a case fan... do I have a crappy motherboard or do those fans plug in somewhere else?
Actually, there are 2 types of power sources for fans. 1 is on your motherboard (these are usually 2 small pins labeled for fans), the other is your regular power supply from your core.
If you'll notice the power wires running to your CD-ROM and harddrive, the have an input, then they go out (like dangling into the middle of space in your case - it is split right where the first plug is).
These are 4 pin IIRC. They look like little plastic rectangles (sorry, I don't know the technical terms, this is not an often discussed area in computers! :-))
I have two 80x80mm ball bearing case fans (they're attached to each other, stacked) on the back of my case (where the only ventalation holes for extra fans lie).
Your motherboard should have at least 3 separate fan output pins (one for your processor, one for your northbridge MB chip, and one additional one). My Abit MB (based on VIA's 266A) has about 5.
Yes, just use the "excess" cables running from your harddrive and or CD-ROM (both almost always require an external power supply)
However, the input interface your fans run on may be different. If it's only the little 2 pin, you need new fans (sorry :-( But, thankfully fans are like $5 a piece
Alright well, here's what it says on the website for the power supply:
"Important Note: The TruePower Fan Only connectors are designed to power standard fans only. Attaching thermally-controlled fans to these connectors will likely result in unpredictable and undesired behavior. Thermally-controlled fans should only be connected to the standard 4-pin Peripheral Power Connectors."
and then here's a pic of what the fans look like that come with my case:
Thank you for all your help.
