MSI Coreliquid 240R and 360R – AiO coolers are replaced due to clogging

MSI has confirmed that MAG Coreliquid 240R and 360R series liquid coolers can become clogged with deposits, greatly impairing cooling performance. Affected customers can initiate an exchange through MSI Support.

Debris clogs gutters

Following customer reports of poor cooling performance of the all-in-one water chiller series MAG Coreliquid 240R and MAG Coreliquid 360R (test), MSI has found the cause after its own examination: there is a possibility that “a deposit forms that can lead to a blockage“, explains MSI and states that only a small part of the CPU coolers are affected. Since the processors are equipped with overheat protection, there is no risk of damage.

CPU temperature over 60°C even at idle

Coreliquid 240R (V2) or Coreliquid 360R (V2) owners should first check if they are affected by the issue by checking the CPU temperature. If it is already above 60°C when not in use, despite correct installation including thermal paste, the channels could be blocked by deposits. Usually the temperature can already be read in the BIOS, as MSI demonstrates with the screenshot below.

Exchange by serial number

In this case, those affected can directly through a landing page request an exchange by providing the product serial number (located on the barcode label) to MSI. A suitable substitution proposal must then be submitted.

“We offer you a hassle-free pick-up and drop-off service for Germany, Austria and Switzerland. Feel free to submit a web ticket via MSI Support if you have any questions.‘ explains MSI. Apparently the problem is not regionally limited, because MSI also points it out in North America.

MSI says it wants to work with its vendors to investigate all potentially affected models.
