"Unsafe" water temp?

[Lays]

Is there a such thing as unsafe water/coolant temps?  How to monitor them?

 

I saw a few things on google, saying ~45-50 is bad. Mentioned tubing getting soft and pumps being at max operating temps.

 

I have "temp sensors" on my fan controller, was debating on seeing how warm the coolant gets but I'm worried about it being electrified or not. ( it's like a piece of wire at the end with plastic over it )

 

I'm mostly just curious to see what the temps of the coolant are during loads/idle etc.  I'm assuming it's room temp at idle, but I was curious as to what it was under load.

NO

There is no unsafe water temperature provided it is below the boiling point at the pressure in the loop and the transition point of your tubing. If your delta T (loop temp - ambient temp) is more than 10-15 C at idle, you may want to take a look. Under load, it depends on the state of the hardware so it is impossible to give out rules of thumb there.

I have heard someone say that the o-rings may go bad in high temps.

[VSG]

Not likely, even Buna based O-rings are fine till 100 C.

boiling is bad. most rubbers and plastics can boil water before they begin to melt.

the hotter your coolant the softer the plastic in your loop gets, this isn't a problem for water blocks.  But it does accelerate pump wear and it does make tubing softer, can especially a problem with thin walled tubing. as temps go up plasticiser leach and discolouration happen faster.

 

the temp probe you got with your controller is a thermo-couple, they are a thermo-electric device that generates a small electric charge when exposed to heat, getting it wet won't be dangerous but could ruin its readings and maybe ruin the device.

 

letting your coolant get hot is silly, there's no good reason to do this.

I run a full loop with 2 GTX 780s @1100MHz and a 3930k @4,6GHz 1,42V constantly folding and I'm running my Corsair SP120s at 1000RPM to keep niose levels down. I don't have any temp sensors in my loop for the coolant but when I pause the folding clients my GPUs drops from 50centigrade to 41c and my CPU drops from 75c to 50c, so I'd like to believe my coolant temp is around 40centigrade. My D5's still going strong and I've not noticed any soft tubing when changing builds, neiter have I notived any leaks because of "soft" O-rings.
