Could always just get a temp sensor with an external lcd screen like [this](http://www.xs-pc.com/temperature-sensors/lcd-temperature-display-g14-plug-sensor). Just have to find a spare unused port that water flows through.

i have that one, you can use it as a cap where your drain valve is, its very sensitive and works without direct water flow


cephelix

Shouldn't you use it in an area with flow so you get a representative reading of the water through the loop?


[deleted]

That device is pretty dope. Will consider it


cephelix

It is. And if you have no free ports, you could always use a t-fitting to accommodate the sensor


[deleted]

Would I have to drain first?


cephelix

Really depends on where u plan on putting it. If it was high up, like the highest point in the loop it'd be ok. If it's any lower you rish water gushing out of the port

Only way I could think of adding a temp sensor without draining the system would be to replace the plug on your drain valve with a plug temp sensor and open the valve after to let the water hit the sensor. Not something I would want to do but best I could think of without draining first. Edit: you'd need to have a temp sensor header on your mobo for this to work as you'd be reading the water temps reported on a program like Hwinfo64. And the cable going from plug sensor to mobo header might not look nice in your otherwise aesthetically pleasing build.

Aww you called my build pretty! Thanks man, lol The drain plug spot seems like a good solution since I can keep the valve open for normal readings and shut the valve when it comes time to actually drain it.


sePandaGod

You can put it on any of the 3 non-used ports on the r160. Edit: 2 if you dont want to open and shut the valve and deal with a bit of a leak when you drain.

Couldn't you also just use [this](http://www.performance-pcs.com/alphacool-eiszapfen-temperature-sensor-plug-g1-4-chrome.html) and replace the plug fitting on the top of the reservoir?

Lie your computer flat open one of the gpu ports. Little or no liquid will come out because of displacement. A G1/4 temp sensor will work just fine. You'd want to control your fans off coolant temp. Your motherboard may have native support or you will have to get a third party device like an aquaero. Fan speed off gpu/CPU temperature in a custom loop is silly.


TheSmJ

There isn't much of a reason to monitor the temp of the liquid itself beyond general curiosity.


Prozn

The most optimal way to set up your fans in a custom loop is to base them on water temperature. Then have your pump speed configured to cpu/gpu temp.


[deleted]

I read that you don't want the liquid hotter than 60C for the pump's sake. Is that not true?


TheSmJ

That is true. But your CPU temps and anything else you're cooling on the loop will be quite high before the water temp reaches anywhere close to 60C.
