CPU Overheating with Water Cooling
SolvedPayeTaBiere -
Hello, I recently built a PC for a friend. I strangely have a CPU overheating at 85°C during the stress test, which causes a frequency drop for safety and also makes the games unplayable since they start to freeze when the CPU temperature rises.
-I've checked all the connections and everything seems fine. I followed the tutorials etc... Everything powers on correctly.
-I've applied new thermal paste.
-I tried opening the case for maximum airflow.
-I've installed the drivers and set the fan and pump to extreme mode.
-I checked the pump's functioning by feeling the pipes, one pipe is hot and the other is at room temperature. And I felt the radiator heating up properly.
I'm out of ideas, I plan to see a pro on Wednesday if I can't find a solution...
Here are the specifications:
CPU: I5-11600K
GPU: GTX 1650 KFA2
MB: Biostar Z490GTA
Power Supply: AZZA ATX650W
Watercooling: iCUE H60i RGB PRO XT

Hello,
There may be a thin protective film on the cooler's square or on the processor that needs to be removed...??
It could also be that you have high temperatures at your place (we don't know)..? or it could be overclocked..??
You also need to consider its environment...? whether it's conducive to heat dissipation, towards the outside, or the clutter in the area..??
This processor is rated for a maximum of 100°; it's better to be below that... with your water cooling, it should be around 70° under load... I deduce that your cooling isn't working well... There should be one hot pipe and another cold...
You need to connect the fans to the motherboard... because there is a power regulation that comes into play, unlike connections with their plugs to the power supply.
Normally, you have software that allows for these adjustments... Your model might be a bit limited in power..?? still, it's possible that you got one that doesn't work well... (in which case, return to supplier)
All of this is lacking numbers. We need to have measurements of ambient air temperatures... of the hot pipe and the cold pipe..??
The completely open casing... is not always the right solution; as they are designed to channel air along a studied path.
And if you take measurements, you will be able to compare the differences..
Aside from that, I'm also surprised... or did you put too thick a layer of thermal paste...??
I managed to fix the problem, but it was by disabling the boost mode at 4.9GHz. However, it's not normal for the boost to cause such a drop in frequency...
For now, 83° must be the maximum with a possible 4.9 GHz and also 191W, but having all three together lasts a certain time before hitting a safety regulation, either by power or frequency since they cut off at the same time. One of the three parameters is enough to resolve it, but we don't know how many GHz you were running. It would be interesting to find the maximum of each parameter without triggering the safety regulation when the other two parameters are not as high.
34° is the lowest in the table at launch. If it's solely due to the heatwave, I won't dismiss it right away. Personally, I disable the boost during the heatwave every year. (The last few degrees close to the maximum are very costly in terms of cooling.)
I found the problem! The Biostar Z490 GTA motherboard is not cooling sufficiently! When it's at high frequency, it reaches 90°C and throttles! (Temperatures seen with HWMonitor). Moreover, the WC is at 80°C when this happens...
I will ask for a warranty return since it's supposed to support the I5 11600K and it's not the case...
I will look into getting a good motherboard with better cooling, like ROG.
There is no decrease in frequency in that...?? What does it represent..?? I see a frequency, a power, and a temperature... without really knowing what it is meant to show..
I was mainly talking about taking a thermometer and applying it to the parts in question to know the temperature...
There is certainly an error or a malfunction..
I may have several solutions to cool the processor for you:
- Check that the CPU is not dusty
- I saw on the internet that you shouldn't open the PC case
- Buy a CPU cooler
- Probably the power supply is no longer functional or poorly chosen for the PC: https://www.config-gamer.fr/guide-achat/guides-achat-alimentations-pc.html
- Install software that manages the processor like Quick GPU
- Probably not enough RAM
There you go..
Hello, thanks for the reply!
There was no protective film.
I did a test with the case completely open for maximum airflow and it doesn't improve the situation.
The pipes seem to be functioning normally, one hot and one cold, and the radiator is hot.
I connected the fan to the available port on the water cooling system so I could control it with the iCUE software; in fact, I set the fan to max in extreme mode and it doesn't improve the situation.
And I checked on an overclocking forum, this model is supposed to do the job well. I’m surprised.
