Water Cooling Temperature Sensors, how many and why ?

Foxy_VI · Jan 9, 2012

Hey all

Been looking at getting some temperature sensors for my loop, to see the temperature of the water ofcourse and at some point maby setup an automated fan control instead of the 5/12v manual fan control im using right now.

i have been looking at these sensors

Though im not sure if the 2'nd one will be restictive if say i place it in the top of this rad rad, instead of the stop fittings.
and, as i am now, still use the side for fittings. it would then have the sensor down right befor the exit or entry of the radiator ?
(don't know if my explanation made sense.

)

Also, having a hard time figuring out how many temperature sensors is usefull, and when they become a waste.
surely 1 would surfice for controlling the fans as only 1 temperature graph is needed.
but i got the impression from reading around on some forums that its not good if there is to big of a temperature difference between two given places the loop, and the only way to know that would be to set up more sensors. (though im not sure i'd know what to do if the difference was to big anyways, as my understanding is that the water would reach an average temperature trueout the loop, only slightly varying from the exit of the radiator, to the exit of a block, given the cooling, heating properties of the two.

so how many sensors do you guys use ? if any ? and why ?
is 1 enough ? and does it matter at all where it's placed ?

Thanks

i have one of the second style. i have it in the top of my res. the water will be pretty much equal throughout.

here's a noob question regarding these things. the two pin connector... do you have to buy some type of temp display unit to make use of these things?

Well, I use the second one as well. It works on the following that I have personally tested:

1. Lamptron FC5 V2
2. Asus Crosshair 4 Formula
3. Asus Crosshair 5 Formula
4. Heatmaster Alphacool
5. Scythe Kaze Server

I am sure it will give you a read out on any fan controller which has a temp read out. So basically it has a two pin temperature sensor plug at the rear. On the two motherboards I have listed, both have a few temp sensor plugs around the board. So it reads out as an OPT Temp in your bios and in software within windows, like HW monitor.

I have the bitspower one (2nd image) and I have it placed in the bottom of my res, just so I have an idea at my temps. I cut off and soldered it to an XSPC LCD temp sensor, and have one of those LCD sensors stock next to it so i can monitor the air and water temp in my case

.
I guess it'd be pretty cool to see the delta t of liquid into rad, out of rad but it wont really be doing anything other than informing you......... how much information do you need? 1's enough for me!

You can have as many as you want anywhere in the loop but I put 2 in each loop. The purpose is to check the cooling capacity and to set in the controller to shut the whole system if any of the temperatures are hitting the set threshold.

And you can not just buy any sensors, the sensor type and value must match the specifications of the controller used to work and to give correct readings such as the thermistor type 10K Ohm, 50K Ohm, 5v or 12v.

I have several temperature sensors connected to Aquaero 5 LT but the ones I really use are Cpu In water temperature and Radiator in air temperature. Delta temperature of those is used to control radiator fans.

Foxy_VI · Jan 9, 2012

you have the 5 LT mm67 ?

How do you like it ? i have been looking at getting it myself. but im a bit torn between the Pro, and the LT version, but if i understand correctly the only difference between the two of them is the lcd display ? they function the same correct ?

i have a MCP35x pump connected to the cpu fan header on the mobo right now, if i where to connect the pump to the Aquaero, how do i get a pwm signal to the mobo header aswell ?

also, fan the LT version run with 3 Typhoon fans, 1 230mm fan and 2x140 fans along with the MPC35x ? without additional power modules ?, the MPC35x shouldn't draw power from the Aquaero as long as the molex plug on it still connects to the psu, and only the pwm is connected to the pwm header of the aquaero ?

Thanks

I do like LT a lot, it's still lacking alarm options that you can set on Pro and XT versions but just about everything else you can do on Aquasuite 2012 already.

You want to send an rpm signal to motherboard so it gives a warning or makes a shutdown if signal is missing ? For that purpose Aquaero has a tach signal output

I'd put 3 Typhoons on channel 1, 230 on channel 2, 2 * 140's on channel 3 and MCP35X on channel 4 which can also run with PWM control. That combination should work with no extra modules.

Do anyone know if it will affect my flow if i place the 2'nd type temperature sensor in the top og the rad as pointed out on the drawing ?

Sorry if this is a dumb question, but

Do you just connect the Tach Signal to the mobo cpu fan header then ?

Also, what are the alarm features you are talking about that is missing ? from what i can read the LT can give a signal incase of problems aswell ?

thanks

Yes, Tacho signal is just connected straight to mb header and this is from Aquaero manual :
Quote:

4.7. Connector „Tacho"
Depending on configuration, the aquaero 5 can generate a speed signal which is available for processing through this connector. This speed signal can for example be configured to cease function upon alarm events and thereby relay the alarm status to a fan connector of your motherboard. Functionality of the speed signal can be configured using the menu entries "Alarm" and "Timer". For details on how to configure your motherboard to process the speed signal, please refer to the manual of your motherboard.

Those Alarm and Timer settings that define how Tacho signal works are not yet available in Aquasuite 2012 software.

i used to have 2 of the first one mounted on the intake from my dual reservoirs. 1 of the sensors never worked properly and after a while i removed them from my loop completly. the second one worked, but i just found it unessesary and i didnt like the wire going from the sensor into my motherboard. I used this on a crosshair V motherboard, and Im positive thy will work on any motherboard that has room for optional temp sensors or fan controllers as well.

Placing the second temperature probe in the rad will not affect your flow. The end of the sensor, only sticks into whatever you plug it in, about 1/4". I have one in my reservoir hooked up to my Lamptron FC5v2. My other three sensors are air intake temp, rear air exhaust temp (120mm rad) and top air exhaust temp (360mm rad).

I use four like of the sensors the op posted put them on in let and out let of my blocks. I hooked the sensors to my Lamptron touch and let my temps control my fan speed based of load temps

sawjai526 · Jan 10, 2012

I have the 2nd sensor plugged to the bottom of my reservoir. pair with lamptron fc5v2. Inform and work just fine for me.
