Hi all I would like to use this PC case fan https://goo.gl/dgRkdU but will it be safe to connect it to the 4/3 pin fan header on the motherboard since it draws quite some power. The motherboard I have is gigabyte z370xp sli gaming and it has 2 fan headers, one for water cool and the other for a normal fan so which one should I connect it to? My GPU run at 83° max and cpu 70°, and PC shutdown twice while gaming so thinking it's probably overheating other something.
So I just want to know if that fan will be safe with the motherboard.
Thanks.

Do NOT connect that fan to ANY mobo fan header. It is spec'd to consume at max 3.3a. A normal mobo fan header is limited to 1.0 A. SOME mobos have one high-power header that can supply 3.0 A, but your manual does NOT claim that for any of its headers.

Alternative? That is an 80mm fan that can push max 133 CFM consuming up to 3.3A and generating noise at 65 - 70 dBA. A Noctua NF-14A iPPC-3000 PWM fan is much bigger - 140 mm size - and can push 270 m3/hr = 158 CFM consuming 0.55 A and noise at 41 dBA.

Need smaller? Noctua NF-F12 iPPC3000 PWM pushes 187 m3/hr - 110 CFM using 0.30 A, noise 44 dBA.

Those are both 4-pin fans. If you want a 3-pin design (your mobo does NOT make it clear which mode - PWM of Voltage Control - its SYS_FAN...
"Noise: 65.0 dBA (Max. 70.0 dBA)"

Do you really want your computer to sound like a vacuum cleaner? : P

A 10 decibel difference will sound about twice as loud to a person, so the 40+ decibel difference between this and a regular 25 decibel case fan should sound over 16 times as loud.
 
Yeah true... Rn I have a 120 mm 5v fan connected to 12v, it sounds like a jet engine but it's not that loud and it pushes some good air around in the case put it's not enough. What fan u recommend?

If you want a 3-pin design (your mobo does NOT make it clear which mode - PWM of Voltage Control - its SYS_FAN headers use) There is the Noctua NF-A14 iPPC2000 model (140 mm size but slower max speed and not 4-pin PWM system) that delivers 183 m3/hr (108 CFM) using 0.18 A, noise 31.5 dBA.

You can get very good airflow with other fans, without going to super-high speeds and noise levels and power consumption.

^ fully agree, that's a server grade fan probably not safe for a mobo header especially when you first power-on, when the PWM settings are not in effect it could cause some problems on your mobo. Grab and Arctic F8 if you need an 80mm fan, they are great for the price.
