Title: PSU fan?
Post by: Martinus on July 27, 2003, 08:04:31 am

[color=66ff00]OK I've now got myself a NF7 mobo, a 2500 Barton and a bit of a problem. :)

I got a nice chieftec case with a PSU built in which seems to have a connector running from it that looks strikingly similar to a fan connector (the mobo thrree pin kind). The NF7 mobo has a receptical for this connector and it's marked 'PSU fan', now here's where I ask the stupid question: Do I connect this connector to the stated receptical or not? I don't want to inadvertantly connect a fan power supply to the mobo and end up with a nice flash and bit of smoke. :nod:

The last time I built a computer from scratch I had to manually set all the jumpers for the processor, it was a bit weird when I saw that there was no jumpers and the bios sets it up for you, technological advancement eh? :lol:

Depends on the power of the fan.  If you are plugging in something that draws a lot of power, ie a Delta Screamer, best to keep it away from the mother board.  If your PSU is just your bog-standard cooling fan, it should be fine on the mobo, that way you get fan RPM read out too.

I would assume it would plug straight in... Motherboard fan headers conform to a fairly standard pinout (GND, +12V, RPM with the RPM monitoring wire almost always being yellow in colour) and generally only go in one way so I'd imagine it'd be difficult to actually blow something up unless of course Chieftech also make motherboards in which case they's have a reason to start ****ing around with the standards.

edit: You might want to wait a couple more weeks before doing anything serious (like installing an OS) on your new toy though. nVidia are supposedly delivering a new set of drivers soon and using any of the previous sets isn't really recommended.

[color=66ff00]Managed to hunt down the pinout, seems it is only RPM and ground so you're right beatspete. :nod:

Should have done this sooner. Doh.

RPM and Gnd? That's unusual, normally power and gnd are fed to the PSU with only the yellow RPM sense wire being wired to go into the motherboard header...

And out of curiosity, what driver revision are you running on that thing?

PSU fan? Nah, I'm more of a graphics card guy myself....

I'm betting it's similar to Antec's Smartpower PSUs. That wire allows the motherboard to control the speed of the fans, but the power is drawn straight from the power supply.
