Posted January 11, 2017 I'm thinking about getting three 120x120x25 PC case fans that will plug into my motherboard. Do PWM fans work similar to the fans on my EVGA 970 GTX whereby the hotter the GPU gets the faster the fans spin in order to cool down the component? Also if it's a PWM fan does that mean it has a 4-pin connector? Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...
Posted January 11, 2017 they're called 120mm fans. they are controlled by the motherboard and they will spin up when the temperature in the case gets higher. idk Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...

I'm looking for 4-pin case fans right that plug into my motherboard for them to be PWM fans? Link to comment Share on other sites More sharing options...

Posted January 11, 2017 PWM (pulse width modulation) is just a way to deliver power. As opposed to DC which varies voltage for different fans speeds, PWM pulses 12v at different intervals to vary fan speed. Either can be controlled just as easily and how each header on the motherboard acts varies depending on the board. Yes, 4pin fans are generally pwm. If you would like fan recommendations, list your specs and explain why you're looking to get new fans.

Posted January 11, 2017 Author Okay thanks I will make sure the fans I order are 4-pin connectors. Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...

Only if you use software to tell them to do that. You can tell 3-pin fans to change speed too, using a program called Speedfan. We have a NEW and GLORIOUSER-ER-ER PSU Tier List Now.

So even if my motherboard has three four pin slots for plugging case fans into I still need software to control the fan speeds? Link to comment Share on other sites More sharing options...

It seems that you're new to the topic and it might help to list your specs and explain why you're looking to get new fans.
