Issue with Volcano 7+

[pestul]

Even if my cpu heats up, it seems as if my Volcano 7 hovers around 2500rpms.. is this a connection issue, is there some other underlying problem or possible defect? Back when I first installed it in this EPoX 8k3a, it used to speed up all the time when the cpu was getting hot.

I've had to reseat it many times (unlocking 1800+.. a few times and recently for my 2700+ installation).

Any thoughts?

What are you using to control the speed? The volcano 7+ comes with a three position switch with med/lo/high setting, no setting for auto, and doesn't have a temp sensor. If you have it connected straight to the mobo header, and have it control the fan speed, you risk burning out the mobo fan header power. The fan pulls too much power to run on most fan headers.

If you are running it on the header, check you bios to see if hasn't been disabled. But I would recommend that you get the three position switch or a rheostat for it. If that doesn't fix your problem, then the fan may be going bad.

Interesting.. I do infact have it connected to the mobo fan header, but of course it has its own powersupply connector as well. I was under the impression that it did regulate its own fan speed because it used to before with my 1800+ :O

I knew nothing about 3 selectable speeds.. so unhooking it from the mobo would be the best thing to do first? I thought that only guaged the fanspeed for software/bios.. didn't know it drew any power.

Oh geez... what a dumbass.. I actually have a Volcano 7 plain jane.. not 7+.

Still, it says its autoadjustable due to temp.. but its staying at 2500rpm.

Try using the power adapter that came with it, if it doesn't help, the thermistor in the hsf may be bad. If you can deal with the noise of it's top speed you could just cut out the thermistor, and connect the two wires and have full speed.

Just realized what you had, the yellow wire is your fan speed wire, leave it connected. Just cut the resistor wires and connect them together. Not even sure if you can get to the resistor though. If it doesn't speed up, then the fan is probably bad.
