80mm smart fan review

It is very easy to combine the two conectors into one, just use a pen to release the yellow wire using the hole in the conector, then just slide it into the other, it works great. I had to do this to use my Volcano 7 due to my motherboards safty feature that needs rpm reading and power load on the cpu fan conector on board.

ther is alot of speedmonitering smart fans out ther

most 80 and 120mm and ther is smart controlers to every fan.

and you kan build one pretty easy, use a ntc resistor and a relay switch to switch from 7v to 12v on the fan.

or get a digital doc insted of the ntc (more flexibel use) i got that an 4standard papst 80mm got three stage faning but use two

stage, silent and cooldown

I think the reason they put the power lead and the fan speed sensor on different connectors is that they thought the power drain from the fan might be great enough that the mobo voltage drop when the fan kicked into higher speed would screw up the voltage needed to run other mobo services (processor, chipset(s) etc.).  If you have a big power supply that reacts quickly to power demands then you may not have a problem. If you have a 300W ATX PS then you may need to use the provided connection pigtail that will connect directly to one of the drive power connectors.

 

I think they were smart doing it the way they did. The user has the option that way. I've got my V7 plugged directly into the mobo but I've got a 425W PS. I may put the connection back onto the provided drive connector pigtail just to avoid any unneccessary mobo power fluctuations.
