Official Water Cooling Thread of the Stock Maximus SE ROG NB Club:

My computer is always under load running SETI... but I ran the OCCT with the slider to RAM for about 10 mins (damn that makes the comp slow lol), NB temps don't budge off 25C

10mn???
Suere not enough to stress your water cooling loop and your NB
Under OCCT last beta in RAM mode, you'll need about 30mn at leats to get your NB heat maxed out. Depending on the capacity of your waterloop, it can take up to 2h for the water temperature to reach equilibrium

Finally, if your window is open, in winter, the ambiant temperature and the chip temperature in a watercooling system have an exponential relation. That is, a 5°C delta in your ambiant can have a 10-15°C impact on your watercooled chip depending if you're on the cold side or hot side of the exponential curve.

The problem with all the results people give, is that most people don't know exactly what they do.

Using Prime95/CSMT/F@H or OCCT RAM, won't give same load on your NB, so when you say load, should be mentioned what proggy. OCCT last beta in RAM mode is by far the best test

Also, people should test at a 20-25°C ambiant to report values. Testing with an opened window, is really not a reference

Here for you some example to illustrate it

I use here Prime95 small FFT for maximum CPU only stress (NB and RAM stay cool at this test)
Ambiant Air 24°C:



Now, Ambiant Air 18°C



CPU Temp is 51°C for 24°C ambiant air . At 18°C ambiant air (digital thermometre) the CPU is at 35°C. So quiet a 2.5x ratio (delta CPU = 2.5 x delta ambiant air).

This is on the cold side of the exponential curve. In summer, above 25°C, the ration will increase and can reach a 3x to 4x around the 30°C ambiant

I just ordered from EK:

(1) EK-NB S-MAX Acetal
- Fittings 1/2" ID

(2) 1/2" ID fitting G1/4

(1) backplate for my CPU.

My opinion, but the MCW30 is by far one of the best WB for cooling the NB. It is based on the Apogee GT design, so a real winner

The best would be really a 1-2h OCCT last beta in RAM mode, and give your NB and ambiant air temperature.
