Do I use the cpu opt fan header?

[djdean7]

Hi I have a Z97X-Gaming 3 mobo and I have ordered the nepton 280l but I'm not sure on connecting it up. Do I put the pump power on the cpu opt header and then connect the 2 fans to the cpu header using a Y splitter? Thank you

I would use the two CPU fan headers for the two fans. Never connect the pump to a variable speed header like the CPU. It has to run at full RPM (full +12V) at all times. If it slows down, it will retard cooling at best and burn up at worse. I have a PWR FAN header that has no control associated with it. I use that header for my pump.

On gigabytes website they say that the cpu opt is for water coolers though :S

Probably because it is has no speed control in BIOS. Or is set at full speed by default. You can use any fan header you want as long as...
1) you set the BIOS to operate that header at FULL speed and not auto or variable speed.
or
2) the header has no speed control associated with it in BIOS.

The bottom line is to not lower the rpm of the pump.

yeah, i just found this out. I built a friend a PC this weekend with a gigabyte board and was wondering why the H105 pump was making strange ticking sounds. I eventually found out i had to put the CPU OPT header on FULL SPEED.

After this i checked my computer and saw my Thermaltake Water 3.0 Ultimate pump speed on my Gigabyte board was 1400RPM, so i set it to FULL SPEED and checked again and it was at 1800RPM! I wasnt running at full speed for about a month or so. I was wondering my my temps seemed slightly higher on my old asRock mobo, and this is why,

I know this has already been solved but imo this is how I set my lioquid coolers up and I build computers for my work so I know what I'm doing =]
1. If the 240 radiator comes with a header that's connected to the pump, I would connect that to either a "Water pump" header on the motherboard or put it on a "chassis fan" header and in the bios keep on disabled so that its always running at full speed.
2. for the 2 fans I would connect one to the CPU FAN and the other to the CPU OPT so this way if the system starts to overheat it will tell the fans to increase their RPMS, you can use a splitter and just connect em both to CPU FAN but I prefer not to do it this way.

Yes, it depends on the water cooling unit. Most simple AIOs with only a 4-wire fan and 3-wire pump need to use the CPU FAN header for the cooling fan, not the pump. But that isn't necessarily the case with more sophisticated liq. cooling systems.

.. I'm sorry pal this is just retarded, did you see his question? Z97X motherboard....

What he needs to do is configure the BIOS and set CPU_OPT to "Full Speed" as gigabyte intended, and plug the cooling fan into CPU_FAN that board is riddled with 4 pin connectors all set to "Auto" by default for air cooling so the BIOS change for 100% running for a water pump is required.

And i'm sorry what board on this planet has a connector labelled "Water Pump" and if there is one please stay away from the piece of shit.

Sorry for reviving a dead thread, but there are actually many motherboards that have a dedicated connector for WC pumps. Some enthusiast level boards from Asus have such connectors, for example.

My Asus x99 Deluxe 2 has a pump header.

You are the one who is ill informed. I suggest you refrain from replying when you are clueless about what you are speaking.
