LED's on Non-PWM fans flicker at low speeds - Page 2

post #11 of 18
Many motherboards have nice fan controls built in Combine the motherboard and GPU with a couple of PWM adapter cables and hubs take most of the work out it.

Thanks, it's pretty interesting. I will read that.

An update:

The PSU calmed down and I could barely hear any sound coming from it at all, but there was some, a quiet one. Yesterday I removed even the built-in ZALMAN fan controller for my two front fans. Problem completely solved.

I wonder what it is that causes this problem? Just out of curiosity, what happens if you use a LNA inline to a fan?

As for good fan controllers, the aquaero 5 LT is an excellent bit of kit with more potential an most will ever need. It has most all the same functions as other aquaero 5 varients, not none of the bells and whistles. All are too complicated for control from a 5.25 bay face panel, but work nicely from keyboard/mouse/monitor. About the only thing the aquaero 5 LT can't do is use the IR remote control. wink.gif

Many users think the heatsink accessory is worthwhile addition. It is standard on other models.

Other accessories can be added as needed

If you are interested, here is link to the manual

I don't know if that came from the LED flicker or some other incompatibility. Fact is something was not right and I nearly damaged my system. Thank god.

Beware of that cheap fan controllers.

Good luck.


This is why I avoid fan controllers. There are a few rheostat-based controllers, but I have learned you can't trust them.

Yeah. Agreed.

I think I will pass. In the future, no fan controllers for me.
My PSU is more important.

You can see what's happening with the fan controller ON. And you can clearly hear the clicking sound coming from the PSU.

Try it without any fan controllers installed. Instead use a hub attached to the motherboard.
