Area-51 R2, AWCC CPU Pump failed
Yesterday evening I opened my AWCC (Alienware Command Center) and saw that my CPU Pump is reading as failed. I have googled this and saw someone suggest running the ePSA diagnostics test - everything passed. But I have uploaded a photo of the temperatures. Are these normal and within range and the "Failed" is just an error? Or do I need to open up the desktop and check things out? I have had this desktop since 2016 and it is no longer under warranty.

The CPU temp looks pretty good to me. The danger zone is when you start getting up around 90C or so. 58C is a very decent temp but remember it depends on how stressed the CPU is. Is that temp at idle, normal use, or running intensive games?

@kouenki
58C is not high for CPU.

Pump failure usually indicates silicate fallout aka Green GOO clogging the pump and cpu block.
The fix for this is to clean the assembly with hot water and replace the coolant with PINK non silicate dropout coolant.
Zerex Phosphate Prediluted Antifreeze
The four major problems relating to cooling systems are:
Corrosion
Cavitation-erosion
Scale deposits
Green-goo or drop-out
The first three of these problems are discussed, in detail, in other sections of the Cooling System TechFacts. However, we are happy to report that the fourth, Green-goo or drop-out, has nearly been eradicated by the introduction of low-silicate, phosphate-free fully-formulated antifreeze. Silicate and phosphate, while valuable as corrosion inhibitors in engine coolant, have limited solubility. That meant that if the antifreeze or additives got too concentrated in the coolant, then the excess phosphate and/or silicate would “drop-out” of the coolant. These “drop-out” problems caused premature water pump failures, radiator blockages, heater core problems.
