Best Cooling Solutions for 9700X Users with ASUS B850M Mortar
Attention, users of the 9700x and ASUS B850M Mortar!
A quick note: The specific model I purchased is the 6000 -C36.
Here’s a heads-up—stay away from the Guangwei Longwu. It caused my motherboard to display a yellow warning light during startup. Initially, I replaced it with a new unit from JD.com, but unfortunately, the yellow light persisted, and I was unable to access the BIOS altogether.
Eventually, I made the switch to the Asgard Valkyrie 6000c28, and everything ran smoothly from there on out.

Absolutely! If you’re looking for alternatives, the NZXT Kraken X63 or the Corsair H150i Pro are both excellent AIO coolers that provide great performance and reliability. They’re pricier than the 6000-C36 but offer quieter operation and more precise temperature control. Thanks for sharing your experience—it’s always helpful to hear from other users. Let me know if you need more details on either option!
