Thermaltake Volcano 6Cu+

How many of you use this fan plugged direct into your motherboard to power it? It drains 4.44W and .37A, and I'd like to know what kinds of mobos and power supplies would work.

If you people powered this fan through the PSU, have you gotten a working setup to detect the RPM through that 1 sensor pin on the mobo?

That's a lotta wattage to pull thru a mobo's fan header, it will fry it. It should be powered by one of the molex connectors. You can split the wiring such that the power is drawn thru a molex, yet the rpm sensor goes to the fan header. This way you have both safe power and rpm sensing. You can do a search on the forum to find a diagram for this setup. If I get time later I'll try to find the diagram and post it for you.

Lots have people plugged it in their motherboard and after awhile when you turn your computer on it will jump start watt more than the 4.44 rated.

You'll take the chance of frying your motherboard since your motherboard usually only supports a little under 4 watts.


I plug mine through the PSU.

As for the RPM why would you want to sensor it? You'll defintely hear it and if its for the purpose that you want to set something so when it reaches 0rpm it shuts down then you'll simply not hear the fan.

See, with my mobo, it has a safety feature on by default where if no RPM info is detected, the system won't boot up. If I can't get the sensor pin to work through 1 pin, as I've read around here (you need a ground wire as well or something), then I'm gonna have to buy a new lower RPM fan, or borrow one to boot up and change the BIOS default for the RPM sensing.

If you have a fan with a 3 pin connecter lying around doing nothing.

Snip the RPM wire on the Everflow fan that is on your volcano snip the RPM wire on the other fan and connect them together and snip the black and red wire on the other fan to disable the fan and you'll end up with your Volcano having two 3pin connecter.

One to go in the 4 pin PSU plug one to go into the motherboard so it detects the RPM.

Here's what I do. Remove the black and red wire from the plugin at the end of the fan wires. Do this by prying back the tiny locking tabs on the side of the plug then the wires should just slide right out easily.
Then, hook them up to the fan wires in the picture (soldering is best). Use electric tape or better yet, shrink tubing.
You can then plug the fans origional plug with the blue wire still in it, to the mobo fan header, and the power to the fan would come from the drive plugins.

This only works at 12 volts or 5 volts and not at 7 volts. The rpm sensor wire (blue) needs to have the black wire on a ground to work.

Drawing more wattage than your motherboard fan header is rated for will definately blow it out. Possibly taking the motheboard with it.

So...only 1 blue wire goes into the motherboard fan header, and the ground is provided through the power supply 4 pin cable?

Basically yes.

I have that fan plugged into the mobo header, it works fine. I'm using an Iwill XP333-R Motherboard. =)
