Q: I want to get this to hook up three *3-pin* case fans and control them through *DC* (voltage) modulation (i.e., not through PWM). I know that I will only be able to control them as a single group, not individually. Can I do that with this cable? The reason I want to buy this cable in particular is that I want to have the option to hook up PWM fans in the future AND because of the great reviews I've heard about it.

Yes, you can use it for that easily.

Q: does this work for 120 mm case fans?

Yes, but to get the pwm feature, make sure they are 4 pin fans.

Q: Would linking two of these together limit performance of fans at all?

Not at all. Works great if your motherboard has limited connectors for case fans or cpu. daisy chaining these makes no sense. They do sell 4 pin molex connectors with 4/4 pin PWM. Do a little research and you'll be surprised by what hardware you can find just by typing in what you want

Q: would this work for ASUS Prime X470-Pro AM4 AMD X470 with these 3 fans connected to the splitter 202001170GP ARGB/1200+~200 RPM/DC12v 0.37A?

This fan splitter will work with either 3 or 4 pin fans/headers. It will work on almost any motherboard and any fan.

Q: Can you use a resistor with this, if so, should it be at the motherboard end, or at each fan end?

I would not recommend using a resistor to control fan speed because your motherboard fan headers will not have accurate control of the fans and can lead to overheating problems and burned out fan headers, it is best to have the MoBo control them directly and fine tune them via software such as Asus AI Suite 3, or if you have them connected directly to your PSU get a fan controller instead.

Q: I have a Corsair crystal 570x and I plan on using this for the front 3 sp120 fans and use the remaining header on my mobo for another sp120 fan on the back of the case. Will this do the job or will it do something weird/cause problems?

You might want to calculate how many amps your fan load is and check whether that exceeds the output on the socket you are plugging into. Otherwise, it is a very simple cable splitter--nothing funky.

Question 1

Is it possible to use this to connect to three led fans?
Will it limit the performance/power draw of all three fans?(weither they be all led or non-led)?

Accepted Answer

You need to check current draw of those fans. Generally you don't want to draw more than 1 A from a m/b header. Fan controllers may support more load per channel. Most likely you'll be fine.

Question 2

In picture there appears to be a gap in the three pin part. How would I connect a 3 pin fan if there's a gap?

Accepted Answer

It is actually for a 4-pin PWM fan. You can still plug 3-pin fans into it, there will just be an extra pin which doesn't plug into anything, and only two of the pins will actually fit into the fan plug. Your 3-pin fans will work fine, they just won't adjust their speeds to compensate for higher case temperatures.

Question 3

Is it safe to connect three 120mm fans to the mb using this adapter?

Accepted Answer

That depends on your motherboard's specifications and the power of your fans. In the motherboard's user manual somewhere, it should list either a max power (W or mW) or max current (A or mA) for the fan connector. Additionally, your fans should have a rated power or current. In order to make sure it's within spec, simply add the current or power of the fans and compare it to the current or power your motherboard is rated for. To convert between current and power, use the following:

x Watts (power) = y Amps (current) * 12 Volts

Example problem, replace with your specs:
If you have 3 fans rated at 0.7W and a motherboard rated at 500mA, then the total power of your fans is 3*0.7W=2.1W and the power for which your motherboard is rated is 0.5A*12V=6W. Since 2.1W< 6W, then it would be safe to run these fans from the motherboard.
