Max safe water temp?

iwrox · 12 Dec 2014 at 19:43

Evening All,

My loop currently consists of 1x240 and 1x280 rad to cool an i7 4770k and 2 290Xs. All 3 components are overclocked....

Idle temps are all good, and to be honest I am not overly worried about the loaded temps either which currently sit at ~52C on the 290xs after 30minutes running around in BF4.

However my LCD readout connected to the res is telling me my water is at 39C which I am guessing is a little high?

So my question, what kind of water temperature should I be aiming for? and I assume more rad space is the answer if I want to lower it?

Cheers

Pumps and tubing tend to have max temp limits of 50-60degC so it's nothing to worry about.

Are the rads in a case? If so what are your in case temps?

Do you have an image of your system? Depending on the OC.. I'd think you would need some more rads, 240mm per 1 OC component. It all depends though on the setup you're running atm. Could you post a picture so we can see? If you're still worried maybe ramp up the fans on the rads?

Your fluid temperature isn't overly high, and neither are your GPU temperatures. Edging towards the high side, but no cause for concern. Remember, the longer your system is running at full load, the higher your coolant temperature will creep.

You would probably benefit from another rad because your just on the limit of what is acceptable for an SLI setup, but as others have pointed out you may be able to get more efficiency with fans speeds or improved case air flow (extracting hot air out of a case is obviously crucial).

I would aim for a full load water temps of 30-35c personally.

Anything more then that then you'll either need to add more radiator or turn down the overclocks.

When I first built my loop the water temp maxed at 50°C.

And although nothing went wrong the tubing did get noticeably more flexible.

However I have now improved my case's airflow and bought better (but much cheaper) fans and max temps water temps are 40°C. I have no issues with this.
