What's acceptable for water temperature?

I've finally got my first custom loop up and running and I dont actually know what an acceptable temperature is for the water.

Cooling my system (5820K, Vega64) is an EK D5 PWM pump, Black Ice 360 GTS, Black Ice 360 GTR (I think, its the 60mm thick multi port one) with Corsair ML120's on both rads.

I've left Heaven running for about 15 minutes now and the temps are as follows;

Water: Fluctuating between 36-39c
GPU: Around 40C
CPU: Around 44-50c (which i dont understand since its only at about 10% load).

The above temps are achieved with all 6 fans at 1000rpm and the pump at 3600rpm.

I'm a bit concerned that when i start gaming and the CPU comes under the load the above temps are going up pretty sharply.

Thanks

You left out a huge piece of information - what is the ambient temp in the room?

Yeah....the little girl hentai avatar is really creeping me out....

Whats your ambient temp? Air in?

My temp different between air and water is at heavy gaming aroound 3,5°(Totally overkill loop).

If you have a temp different of 0-10° is good. lower is better ofcourse

Unfortunately i dont have anything measuring ambient temp at the moment. I'll attach a temp sensor to my Aquaero 6 and just leave it dangling outside the case.

I'm now running AIDA64 stability test (not GPU, just CPU) and the CPU cores are dancing arround the mid 60's with the water temp around 35. Is it normal for the CPU to run that much hotter than the water temp?

Hi,
Funny you don't know or can tell what temperature is in the room you're sitting in

les than a few C above ambient.

if I remember, most of us with well radiated systems have a 1-3c delta.

based off the info given, you're doing just fine.

R.I.P. Zawarudo, may you OC angels' wings in heaven.
If something appears too good to be true, it probably is.

While gaming the water temp seems to top out at about 41c. Is that too high? I'm using Mayhems soft tubing FWIW.

41c is fine. On my Aquaero 6 I have my loop temp set warning set to 45c and alarm set to 50c. Anything past 50c could degrade the tubing, and 60c will soften tubes.

You should set up the ambient temp for permanent use. With the ambient temp your AQ6 could control your fan curves and even your pump speed off the Delta (difference) of your ambient and your loop.
Under Virtual Temperature Sensors you would create an "Absolute temperature difference" sensor based on your Loop water temp (Sensor 1) and Ambient (Sensor 2).

Use that value to drive your fan curves. Your loop can only remove so much heat until it reaches equilibrium. Basing your fan speed on the Loop Delta allows you to maintain stable temps based on your preferred sound levels.
The AQ6 excels at this stuff. Use it.

0-50C is acceptable.
