XPS 8950 Overheating
After months of waiting I finally got my XPS, not the one I ordered, but the successor XPS8950, but that's also nice...
But now to the problem. I tested a few things yesterday and under heavy load on the CPU I noticed that it smelled a bit funny. I touched the tower and it boiled. At the water cooling the radiator was no longer touchable without getting burned, HWMonitor reported 100°C on all cores! The fan on the radiator as well as the front did not turn up! I then immediately put the "Rear FAN" on "CPU FAN" and lo and behold, the temperatures stayed below 60°C. But now the system complains at startup, "rear fan error". There are no settings for the fans in the bios.
The system is VERY strange, have never seen that you can not get to the settings of the fans ... In the diagnostics, the two fans show that they can rotate VERY high, but they do not!
How can I set the fans?! How do I get the curves for it?
---------------------------
Nach Monaten des Wartens habe ich endlich meinen XPS, nicht der bestellte, sondern der Nachfolger XPS8950, aber das ist auch nett...
Nun jedoch zum Problem. Ich habe gestern einiges getestet und bei starker Beanspruchung der CPU merkte ich das es etwas komisch roch. Ich habe den Tower angefasst und der kochte. An der Wasserkühlung war der Radiator nicht mehr anfassbar, ohne sich zu verbrennen, HWMonitor meldete auf allen Kernen 100°C! Der Lüfter am Radiator sowie der vordere drehten nicht hoch! Ich habe dann sofort den "Rear FAN" auf "CPU FAN" gesteckt und siehe da, die Temperaturen blieben unter 60°C. Doch nun meckert das System beim Start, "rear fan eror". Im Bios gibt es keine Einstellungen für die Lüfter.
Das System ist SEHR merkwürdig, habe noch nie gesehen das man an die Einstellungen der Lüfter nicht heran kommt... In der Diagnose zeigen die beiden Lüfter das sie SEHR hoch drehen können, nur tun sie es nicht!
Wie kann man die Lüfter Einstellen?! Wie komme ich an die Kurven dafür ran?

Kleiner Nachtrag:
Nach einem Update des Bios ist das ganze schon kein Problem mehr mit Überhitzung. Aber! Die CPU überschreitet dauernd die 70° Marke und wird dadurch gedrosselt. Ob Schäden durch die Überhitzung zurück geblieben sind, wer weiß es. Der Wasserkühler muss früher eingreifen, so ist das schon beinahe sinnlos ...

I had the same issue with a brand new 8950 *with* the liquid cooling option. HWiNFO showed that all the performance cores (CPU is a Core i7-12700K) hit a temperature 100C, all the efficiency cores hit 97C, and that thermal throttling had been initiated. I should have figured out sooner that there was an issue, as after gaming for a while the system case was quite hot to the touch and you could feel it radiating heat. I only decided to look into it when Steam crashed.
It looks like upgrading to BIOS 1.0.8 has improved the situation significantly. (Note that this had to be downloaded and applied manually, because Dell Update didn't report it as being an available update.) However, the cores still get up to the high 70C to mid 80C range, which is not ideal. I wonder if it is possible to adjust the fan speed curve. Even after the BIOS update, the fans are not running as fast as they could. (The Dell diagnostics app ramps up the fan speed and the fans get quite loud -- much louder than they currently do when the CPU is running at 80C+.)
Dell Support ultimately resolved the issue, but I sense it was more by luck than by understanding what the was causing the issue. It seems that applying any updates is a standard part of their troubleshooting and the BIOS update is what resolved the problem. However, I was a bit frustrated, as they told me that because my system had passed the Dell diagnostics, if the problem continued then it meant it was a software issue and I would need to pay for support. I would argue that with a properly designed and functioning system, it should not be possible to overheat the CPU, so if it happens, it cannot be a software issue. (When I build a system, I run Prime95 to stress the CPU and make sure the temps don't exceed a reasonable temperature. If it doesn't overheat with Prime95, it's not going to overheat with gaming or any other software.)
I respectfully asked to speak to the rep's supervisor. The supervisor essentially echoed the same sentiment. However, after inspecting my system, he recommended that I should upgrade my RAM from 16GB to 32GB. I think it was at that point that I lost all hope. If someone thinks that upgrading a system's RAM will prevent a CPU from overheating, their knowledge of computers is pretty limited. Also, he was unaware that liquid cooling was an option for the 8950. He initially asserted that it wasn't, until I persisted and he looked into it further.

I spent 2h with Dell premium support today, also showed that the water cooling system lost water due to overheating (which is a total loss for an AOI in my view). Tests were made (bios I had already updated) and said everything is ok. That the pump has become louder since the overheating? Was no matter. That Intel 12gen processors clock down at 72 degrees? No matter! I'm ****, that was 2h of my time in which many technical errors were made and I felt the employee still trained!
