Nova25 Posted February 9, 2016 Share Posted February 9, 2016 I'm currently in the process of upgrading my system and I am looking to install a liquid cooling unit on my GPU but curious where the pump/fan headers will go on the motherboard. I have a GTX 980 Ti ACX 2.0 (http://www.newegg.com/Product/Product.aspx?Item=N82E16814487142) that I'm thinking of putting the HG10 N980 cooling bracket on paired with a H60 or the like.. I already have an H60 cooling system on my CPU with the connections going to CPU connections on the motherboard. If I install an H60 on the gpu with this bracket do I just run the connections to any system fan headers on the motherboard? Do I need to be worried about any voltage settings for the pump with it in a system fan 1/2/3 header? For example this GIGABYTE G1 Gaming GA-Z170X board, can I just plug the fan and pump connections into the system fan headers under the USB 3.0 connector and the one on the bottom right of the board?

Toasted Posted February 9, 2016 Share Posted February 9, 2016 Yes, you can plug the pump and fan into a different fan header on the motherboard. Just make sure fan control is either disabled or set to run at maximum speed all the time. Yes, it will be fine as long as you make sure the fan control settings are either disabled or set to run at max. speed. Link to comment Share on other sites More sharing options...

Nova25 Posted February 9, 2016 Author Share Posted February 9, 2016 Thanks Toasted! You seem like you know your stuff, let me throw this other questions at you if you don't mind. In this Thermaltake V71 case I'm going to have the CPU radiator mounted to the top with the CPU radiator/fan exhausting air out. If I mount the GPU radiator/fan to the bottom of the case would you recommend it also exhaust air out, or should it intake air in from the bottom? Edit: I'm thinking putting the radiator on the bottom for GPU pulling air in from the bottom into the case, with that and the front 3 fans as intake... and then the top rear, one top, and top radiator exhausting... If that makes sense? Seems good? Link to comment Share on other sites More sharing options...
Toasted Posted February 10, 2016 Share Posted February 10, 2016 Intake from the bottom will probably work better than exhausting. Or if it can fit, mounting the radiator to the rear may work as well. Link to comment Share on other sites More sharing options...
keilau02 Posted February 10, 2016 Share Posted February 10, 2016 Pump only, The fan can be controlled. If I connect the GPU cooler fan to a controlled header on the MB, wouldn't fan speed be controlled by the CPU temperature? I would expect that you want to control the GPU cooler fan speed by the GPU temperature. Does the GPU usually run hotter than the CPU? I know it depends, but just "usually"? Running the fan at maximum speed is not an option. The Corsair 120mm fan is somewhat noisy at 2000 rpm. Link to comment Share on other sites More sharing options...
Toasted Posted February 10, 2016 Share Posted February 10, 2016 If its available, a custom curve will probably be the best option or get something like the Commander Mini or a fan controller similar to it. For older GPUs, probably. With the modern ones, i think they are nearly the same, just depends on what kind of cooler is on it and how good the case airflow is.
