It will work, the 4th pin will simply not be connected to the fan controller. Don't waste money buying a PWM specific model btw if you are using a fan controller for them

This is why you should not get an FX CPU for ANY scenario other than rendering on a budget http://linustechtips.com/main/topic/286142-fx-8350-r9-290-psu-requirements/?p=3892901 | http://linustechtips.com/main/topic/266481-an-issue-with-people-bashing-the-fx-cpus/?p=3620861

You'll not be able to control their lower end rpm speed (they will not spin until they reach a certain % load) with simple voltage regulation (the third pin on the connector), but no big deal. :)

Umm... yeah... why not read the whole post before replying? This is about connecting 4pin fans to 3pin fan controller. Controller will be able to lower speeds to what ever is min volts that fans will use.

^^^^ That's my post ^^^^

I read the whole post and this is what I answered, in other words: It is perfectly fine, the only downside is that you'll not be able to control the fans rpm speed as fully as with using that 4pin fan on a PWM fan header.

No offence, but we're all here to help each other, let's not make pointless discussions please.

Also, english is not my native language so sometimes I phrase things the way I think is right and not the way someone whose native language is english would.

"what ever is the min volts that fans will use" will make those fans spin faster than if they were connected to a PWM fan header, which is kind of like wasting the PWM feature.

The forth pin (which you'll be missing) is the PWM controller. It let's you control the fan RPM further more than only a DC fan (3-pin).

With 3-pins, you'll still be able to control the fan's RPM but it'll not be as accurate and efficient as PWM/4-pin. Google helps as well, but here's a good post and also here.
