¿Problems with my Corsair cooling?


Recommended Posts

Hello everyone.


I'm writing this because, following some problems I've had with the temperatures of my new CPU (i9 12900k) I'm starting to think that my Corsair cooling is faulty, and I'd like to confirm or deny it. I won't talk about the temperatures as I'm going to expose the data of my cooling to see if the problem comes from this one. PS: The iddle temperatures are correct.


I have a Corsair h150i Ellite Capellix liquid cooler. 
The maximum RPM of the water pump is 2660.

Is this normal?

The water temperature is 30 degrees at idle with an ambient temperature of about 22 degrees, playing around it can even get above 40 degrees, although I don't know how high it can get. Tomorrow I will try and edit the post or quote you.

So, is this also normal?

Facts: My computer case is an iCUE 5000x

With 3 SP120RGB Elite fans pulling in air
One pulling out
All three liquid cooling fans drawing air from inside the case. I have to look at the max RPM of these fans as well, I'll edit tomorrow.


Thanks

30C idle coolant temperature is fairly common. While room temperature plays a heavy hand in your value, ultimately it’s the internal case ambient temp that is the minimum possible value. See what any of the various monitoring programs reports for your “motherboard temp”, which is typically near the PCI-e slots. I am expecting something like 27-28C and that makes a 30C coolant pretty much right on the mark. 
 

In mixed gpu+cpu loads like gaming, I expect the coolant to hit 40C. +10C rise during gaming is about average and most of that is a result of the rise in case temp from the gpu activity. If you run a cpu only max test with moderate-high fan speed, I would expect a coolant rise of 6-8C after 10 min with a 220-250W output from the 12900K.

La temperatura del refrigerante de ralentí de 30C es bastante común. Si bien la temperatura ambiente juega un papel importante en su valor, en última instancia, es la temperatura ambiente interna de la carcasa el valor mínimo posible. Vea lo que informa cualquiera de los diversos programas de monitoreo para su "temperatura de la placa base", que generalmente se encuentra cerca de las ranuras PCI-e. Espero algo como 27-28C y eso hace que un refrigerante de 30C sea bastante correcto. 
 

En cargas mixtas de gpu+cpu como juegos, espero que el refrigerante alcance los 40C. El aumento de +10C durante el juego está en la media y la mayor parte es el resultado del aumento de la temperatura de la carcasa debido a la actividad de la GPU. Si ejecuta una prueba máxima de solo CPU con una velocidad de ventilador moderada a alta, esperaría un aumento del refrigerante de 6-8C después de 10 minutos con una salida de 220-250W del 12900K. 

Hello, thank you for your reply.


So, I see that the water temperature is normal. And what about the RPM of the water pump, are they normal? If I set it to extreme on iCUE it only reaches 2660 RPM.
The radiator fans only reach 1900 RPM or so each, in Extreme mode in iCUE.

If you tell me that this is normal, I will stop worrying about the cooling.

My motherboard and water temperatures, after 15 minutes with the computer on. (When I turned it on, the water was at 20 degrees, it was slowly rising).

PS: I've read on the internet that there are sensors that the motherboard doesn't have, and HWiNFO gives a random value, hence the 127 degrees of some components x)
PS2: I had to undervolt the 12900K. I read that it's almost mandatory unless you have custom liquid cooling. And so I did it without losing performance, but I would like to know if everything on my PC is working properly, including the cooling.

Thank you very much for the time you take to read and answer me.

The pump speed range is fairly narrow on the Elite coolers with Quiet (low) delivering around 2200 rpm and Extreme (high) about 2700 rpm. 
 

The fans have a free air maximum speed of 2000rpm, but when faced with the airflow restriction from the radiator 1900 rpm is about as fast as they will go. However, there aren’t too many occasions where you need to run 1900 rpm on a 360mm radiator.
 

The CPU is heated from voltage applied at the pins underneath. That heat is then conducted somewhere else. This is how all cpu coolers work, regardless of type. In a liquid cooler the heat is conducted into the water stream which then acts as a transport mechanism to the radiator where the fans blow some of the heat out. So with fan speed you are regulating the liquid temperature, not the cpu directly. The relationship between liquid temp and cpu temp is additive and liquid temp is the lowest possible cpu temperature with zero volts. If the liquid temp increases by 1C, then cpu temp will be 1C warmer as well. The same is true in reverse for cooling. So if increasing fan speed from 1500 rpm to 1900 rpm reduces coolant temp from 40C to 39C, you only reduced end cpu temp by 1C. Unless you are right on the edge of your personal cpu temp limit, you usually can let the fans run at moderate pace and get 99% of the cooling benefit with drastically reduced noise. 
 

CUE doesn’t always read motherboard data in the intended way. The embedded controller in Asus boards seems perpetually difficult and junk values like 216C or 16C are common filler values from the ends of the scale.  Those can be deleted from the CUE dashboard.

Hello, thanks for your reply again.

After seeing your answer, I am starting to be calm because I see that my cooling is working normally. It was just that it was quite necessary and common to undervolt my CPU.

I was testing yesterday.


Playing Cyberpunk 2077 for an hour and with all settings on max, including RayTracing and 2k.

The radiator fans maxed out at 2200-2300RPM each. Running at an average of 2100RPM.
The Pump, in balanced mode, was always running at about 2450RPM. (Maybe I should put Variable Speed inside iCUE?)
The water did not go above 39.5 degrees, all this with an ambient temperature of 21 degrees, and the 3080 working at a temperature of between 78-82 degrees.

I understand that the cooling then is working correctly, and that is very good for me.

I look forward to your reply to confirm, thank you very much again.

You only have the option for the three fixed pump speed on the cooler, so pick one that is quiet for the desktop.  It is not going to be the determining factor when running mixed loads like gaming.  When you are under GPU load, the device will be the one producing all the heat and this raises the internal case and coolant temperature, even if there is no CPU activity.  It is common when gaming to see higher than expected coolant temp because of the increase in case temperature and this further changes depending on where the radiator is located.  Above the GPU as exhaust is more likely to be affected.  However, you can't cool the liquid below the case temp, so you likely do not need or benefit from 2000+ rpm type fan speeds with moderate CPU load.
