Oh well something seems to have happend to my controller, Was working fine on settings 1,2,3,4,5

Left it to run on setting 4 which it did for 30mins then stopped.

It will now only work on setting 5, which is ok, but still abit loud for my liking.

Fan is RVK 150L1, in dr120,so Iam thinking that perhaps the fan is too powerful for the controller.

Feck it!

Looks like a variac form here on......

Does anyone know how many watts the rvk 150L1 uses?

The wac1 controller can handle up to 75 watts, so Iam thinking still, that the fan is drawing too many watts for the controller to handle on any other setting than number 5.

Any help would be greatly appreaciated.

it's over 75 watts, and yeah, it's too powerful for the controller,, a high powered 125mm is generally around 85watts

Thanks Scraglor,

Time to build a variac.
