How many chassis fan headers does the EVGA Z270 STINGER motherboard have?

[Cookiesaredeliciousyay]

I looked up the specs on their site and they say it has "Fan Headers - 3 (2 PWM, 1 DC/PWM)" Does that mean 2 chassis fan headers + a CPU fan header? I looked up a review of the Z170 STINGER and it said it only had 1 chassis fan header, but when i looked up the specs on EVGA it said "Fan Headers- 3 (1 PWM, 2 DC/PWM)"

The EVGA Z270 STINGER has 3 fan headers: 1 DC/PWM header is located at the upper left portion away from the CPU, while the 2 PWM headers are side-by-side and located at the upper right portion away from the CPU.

The EVGA Z170 STINGER also has 3 fan headers: 2 DC/PWM headers are located away from each other, 1 at the upper left portion from the CPU and 1 at the upper right portion from the CPU, while the 1 PWM header is located directly above the CPU (between the 2 DC/PWM headers).

Note that the DC/PWM fan headers are default selected as DC (voltage-controlled). If you want PWM functions (current-controlled) for PWM fans, you must enable this header settings in BIOS.

CPU fan headers are usually PWM fan headers:

In the case of the Z170 STINGER, it is clear in the manual that the single PWM header (located directly above the CPU) is the "CPU Fan Header" as verbatim/stated, so this means the 2 DC/PWM fan headers are for your case fans.

In the case of the Z270 STINGER, the manual does not categorically state which is the CPU Fan Header. But as above, the 2 PWM headers located at the upper right portion of the CPU would function as the CPU Fan Header (similar to the CPU_FAN and CPU_OPT in other motherboard brands). The single DC/PWM header would serve as your case fan header. Technically though, if you'll only be using one of the PWM headers for your CPU Fan, then you'll still have 2 fan headers to use as your case fan headers (1 DC/PWM and 1 PWM).

Ok, thank you . One further thing: I plan on using 5 fans in my case- Two attached to a Noctua NH-U9s and plugged in with a Y cable to one header, two Noctua intake fans on the bottom and plugged in with a y cable to another header, and 1 rear exhaust fan plugged into the 3rd header. My question is: would i run into any problems with the y cabled fans overloading a header? or, would both fans function on each header, even?

You're welcome. Your CPU Cooler, the Noctua NH-U9S (http://noctua.at/en/nh-u9s/specification), includes two NF-A9 PWM fans that has a rated max. input current of only 0.1A per fan (http://noctua.at/en/nf-a9-pwm/specification). With two attached to the CPU cooler and plugged in via a Y-splitter to a PWM header on your motherboard, the fan header would only use up 0.2A to power those two fans -- entirely safe.

For your two bottom intake fans, assuming those Noctua fans are the same as above, then the header connecting these two fans would also use up 0.2A -- entirely safe.

A rear exhaust fan plugged into the 3rd header would have no issues (in fact, the rated ampere draw of this case fan, if non-Noctua, might even be close to ~0.4A -- the total ampere draw of all your 4 Noctua fans!)

Yaaas! Though according to http://www.relaxedtech.com/reviews/noctua/nh-u9s/1 the NH-U9s actually only comes with one NF-A9 PWM fan. On the link you sent me under "scope of delivery" it only mentions one fan. I could be wrong though.

Yes, you are right. I should have said "the Noctua NH-U9S... includes **one** NF-A9 PWM fan that has a rated max.... With two attached to the CPU cooler and plugged..." (as you have added another Noctua fan to that CPU Cooler that comes with just one fan).

Mkay, gotcha. One more question >.<: i think ima choose the asus ROG Strix z270i motherboard instead. BUT under specifications page it says it has 1 CPU fan header, 1 chassis fan header and one AIO_pump header. Would i be able to to plug my last case fan into the AIO header? Im guessing yes, but i just wanna be sure.

Yes, the AIO_PUMP header is similar to the other fan headers, the only difference is it is default run at Full Speed (as opposed to the other headers default run as Q-Fan Controlled via Asus BIOS). You can still change the Full Speed settings in BIOS though. If not, fans plugged in the AIO_PUMP would run at 100% speed.
