Corsair fan only cable?

Is the fan only cable on my Corsair HX520W PSU a lower voltage? Is this why it is "fan only"? If so, would plugging a regular cable into the fans rather than this one make them spin faster? My case temps are a little warm.
 
Im currently using the fan only cables-sorry I didnt specify that-so do you mean that on the fan only cables it adjusts the fan speeds? As a result, would plugging in a normal cable keep them at max at all times? Is that what you meant? I dont mean to question you, it just seems counterintuitive otherwise.

While we are at it, is there any way of plugging the Corsair PSU into the mobo so I can read its fan speed? My mobo (P35C-DS3R) has the socket, but the PSU doesnt seem to have a cable for it.

Yes plug fans into Mobo headers or other non fan only molex and you will have 12v and full speed all the time.
 
No, by fan only, its a molex with the 12v and 0v only on it and splits it. Its a pointless cable tbh. You can plug a fan molex in to any molex.

Yes it's a lower voltage. I can't remember what it is but it's either 7v or 5v. I'd guess at 7v but it's easy to check it if you have a multimeter. It's labelled as fan only because it's wired to provide a lower voltage. So don't ever plug a fan only molex into a HDD or whatever unless you want it to blow.

As said already by others you can plug a fan into a standard 12v molex to get it to run at full speed.

No, it will slow then down depending on temps and at most speed up to max speed which is same as you have now, as its 12v.
The Corsair HX520 has no temperature controlled fan speed feature for case fans. Unless you mean the fan in the PSU which is temp controlled.

No, by fan only, its a molex with the 12v and 0v only on it and splits it. Its a pointless cable tbh. You can plug a fan molex in to any molex.

As I said above it reduces the volts from 12v to either 7v or 5v (I'll check it later with a multimeter). I find it useful to slow down my 120mm case fans so they run very quietly so I wouldn't call it a pointless cable.

I have followed this thread with interest and it was becoming very confusing to put it politely.

I'm not in a position to debate the issue but your contribution str appears most helpful.
 
I gave my answer based on older Antecs, Fan Only Molex's slowed fans down and when case got hot, the PSU sped fans back up, aswell as its own fans.

Now I dont own this Corsair so didnt know about the function and did not know it dropped volts 24/7 and was not TEMP controled but its same idea that fans normally will not be full speed as they get a reduced voltage.

Now if you wire fans to Mobo Headers or Normal Molex's you get 12v and full speed 24/7, WTF is so hard to grasp about that. :confused:

And Marse, I was the 1st to actually give some help to him at least.
 
Thanks for all the help-I tried another cable and it didnt make a difference, so Ive just ordered some new fans with a higher RPM instead! I didnt mean to cause any arguments by the way-this cooling thread seems to have got rather heated. Wow, thats bad!
