Phanteks P400 stock fans (AF or SP?) and fan configurations

[dkD0nkeyniks]

Are the stock fans that come with with the Phanteks P400 case Air Flow and Static Pressure?

In addition; what should my fan configuration be? I was thinking off getting the twin pack for corsair AF-120 (if the stock fans are SP) or SP-120 (if the stock fans are AF). Unless y'all can suggest better case fans (preferably on the cheap side)

My idea was to have SP fans as front intake (top and bottom) to counter act the dust filters (don't want to remove them) and have one AF fan as a front intake in the between the SP Fans. Then have an AF fan as rear exhaust.

I am trying to keep my system as cool and quiet as possible while gaming, so any and all advice/suggestions are welcome

The Phanteks P400 case web page does not specify what fans it includes. But its photos show they are 9-blade all black fans, and from their fan lineup that appears to be their PH-F120SP-BK fan, a 3-pin design that draws 0.08 amps max each. For front intakes you do not need Static Pressure fans - the intake dust filters are not supposed to be significant airflow restrictors. Static Pressure fans are designed for use with closely-spaced cooling fins of a heat exchanger, which are more restrictive to air flow. So I'd suggest you need only to add Air Flow style fans at the front. The case is shipped, I believe, with its two fans mounted one front, one rear. You're considering the Corsair AF120 fans in a twin pack. Just be sure to get the "Performance Edition" models that deliver much more air flow than the "Quiet edition" models. These also are 3-pin design and consume 0.13 amps max each.

To power and control the speed of those 3-pin fans your mobo must use Voltage Control Mode. In fact, its SYS_FAN1 header does do that according to its pin labels on p. 24 of the manual. (The SYS_FAN2 and PWR_FAN headers do NO control at all, so don't use them.) How to connect all four fans to a single SYS_FAN1 header? Actually, easy. First note that the combined current draw for the four will be 0.42 amps, and almost all mobo fan headers can supply up to1.0 amps, so no problem. Next, get yourself three Splittters like this

NOTE that this item has one input arm with holes in its connector, and two output arms with pins. Do NOT get a Hub, which is a different device that can look like this, but has an additional arm with a power connector that must plug into a PSU output.

Take two of those Splitters and plug them into the two output arms of the third. The resulting "stack" converts a single mobo header into four output arms for fans.

Hey thanks for reply. Took your advice, but instead went with two AF140s on the front intake instead. I ordered the splitter you posted.

do you know if Speedfan will be able to control each individual fans separately? since they are all plugged into 1 header through stacked splitters.

in other words can speedfan allow me to, for example, set the 2 front intakes to spin at 50% and the 1 exhaust to spin at 45% if CPU reaches 45 degrees?

All Speedfan does is alter the configuration parameters of the mobo's automatic speed control system. So it is that system's abilities you are asking about. When you connect several fans (using either a Splitter or a Hub) to a single fan header, all the fans on that device share the SAME control signals. The only way to send different signals to several fans is to connect each singly to its own fan header and then configure each header differently.

In your case, you'll have two Corsair AF140's on the front and and two Phanteks PH-F120SP-BK 120mm fans at rear. All four will receive via the splitter from a single mobo header the same voltage signal. The two front fans, being identical, will tend to run at very similar speeds. The two at the rear, being identical to each other, will also run at their own similar speeds. BUT the front fan speeds will NOT be the same as the rear fan speeds because the two different designs have different speed-versus-voltage curves. But all that does not really matter for control. The mobo's aim is to move whatever air it takes to get the TEMPERATURE at its sensor to the right place, and it really does not care what speed the fans are doing to achieve that.

ok thanks! would you happen to know the safe temps for my MOBO? Im getting these temps while web browsing Using Open Hardware Monitor:

Temperature #1: 38 C
Temperature #2: 49 C
Temperature #3: 32 C

EDIT:
Used CPUID HWMonitor and these are temps (with new names) I'm getting with the MOBO:

System: 39 C
CPU: 49 C
TMPIN2: 32 C

No, I don't know specific temps for your system. But those temps look on the cool side for most systems I've seen around here, so do not worry.

ok thank you for helping me!
