Hi,

This is my previous thread explaining the situation

So if I have understood correctly, I can control my Apache Black and the fan on my Gelid using speedfan (which I can, that is working), but have I understood correctly that I can also control the speed of my Blue LED THREE PIN fan that came with my CM Elite 430 Case??

I have connected it to the PWR_FAN connector on the mobo, and 3 fans show up on the main part of speedfan, if I change the percentage on two of them it actually does something (apache and gelid fan) but the third one doesn't seem to have any effect

Any ideas? It is the first time I have ever used speedfan so please try to explain anything as best as possible

Thanks in advance,

This one?

Two thoughts, maybe the PWR header can't adjust speeds via Speedfan? Have you tried the offending fan on a CHA_FAN header?

Secondly

Not too sure but the product page states 2000 +/- 10% RPM, not something like 800-2000 like some others do, maybe it doesn't support PWM? Something to do with LEDs dimming when running slower (lower voltage)? IDK sorry!

Hmmm not quite, similar, but my fan casing and blades are clear plastic

I haven't tried it in a CHA_FAN header yet as I need an extension cable, I have already had to move it to the side window instead of the front for it to reach the pwr_fan header, lol

I might connect it to the CHA_FAN header tomorrow, not actually screwed on, but just sitting there and see what happens. Problem is the CHA_FAN headers are 4 pin and the fan is 3 so how would I do that?

What you are saying about the LED's does make sense


Thanks for the help,

3 pin fans will fit a 4 pin header, just look at the plastic notch on the header/fan plug, line em up and bypass the spare pin
