Is it OK to turn off the fans on a custom liquid cooling set up?

I just wondered if you could turn of the fans on a cooling loop at idle if you have enough Radiator space or if the coolant would heat up too much.

sure, but it'd be wise to monitor the water temp to make sure it isn't getting too high which can cause major problems (50°c is max water temp I've heard).  You may need to keep a couple fans running at a low speed depending on the rads and where they are.  I used to just run all my fans at <750rpm at idle and they were very very quiet, now they all stay at 1200rpm all the time

If you have maxwell card then its ok to have fan turned off but make sure you use speedfan or mobo fan settings. Let the pump run and fans would start at 40-45`C caring about CPU and GPU temp

There are a lot of variables, your GPU and CPU are all ways going to be generating heat, that water is going to start getting hotter and hotter. You would need to have a lot of water in circulation to passively dissipated that heat, at or faster than it's being generated. I would hook up some higher quality fans and work out some fan controller that can speed up based on the water temp or system usage.
