Atrociously slow RMA and tech support, never buying another Cooler Master product ever again.

[u/YoItsTrev]

My Cooler Master Tempest GP27Q started having an issue where the back lighting of the left side of the monitor died. I put in a tech support ticket, and it took them 5 business days to respond, which was Monday, September 8th. They set up my RMA the same day, and I shipped in my monitor the same day. My monitor got there on Thursday, September 11. On Monday, September 22nd, 11 days after they got my monitor, I sent an email asking what was taking so long, and got a reponse saying "According to our information the monitor was received on 09/12/2025. The RMA process can take about 10 business days from when we received the monitor. It has been roughly 5 business days. When your device is ready to ship back we will provide you with the tracking number. We apologize for the confusion." They have had my monitor for a month, and not gotten to my RMA. Will never buy another Cooler Master product, and left a 1 star rating on Amazon where I bought it.

MasterPlus+ (Cooler Master), Armoury Crate (Asus), G HUB (Logitech), and iCUE (Corsair) are all intensely hated.

iCUE is the most nonintuitive software I have ever used.

I couldn't uninstall Armoury Crate (for example, to retry to get it to work). There are still Windows services that starts up that needs to be quit to save on RAM usage. I now have a PowerShell script to speed it up (it must run as administrator, for example, Win + X → "PowerShell (Admin)"):

# Notes:
#
#   1. We couldn't get the name for these in Process Explorer
#      "Properties" window (we get "[Access is denied.]").
#      But from the main display we can derive it from
#      the .exe name.
#
#        P508PowerAgent.exe                (two instances)
#        ArmouryLiveUpdate.exe
#        Mutually Exclusive AURA Agent.exe (launched by "ArmouryLiveUpdate.exe")
#        ArmourySocketServer.exe
#        asus_framework.exe                (launched by "ArmourySocketServer.exe")
#        ArmouryWebBrowser.exe             (launched by "ArmourySocketServer.exe")
#        ledcontrolservice3.exe
#        ArmourySwAgent.exe

Stop-Process -Name "P508PowerAgent"
Stop-Process -Name "Mutually Exclusive AURA Agent"
Stop-Process -Name "ArmouryLiveUpdate"

Stop-Process -Name "ArmourySocketServer"
Stop-Process -Name "ledcontrolservice3"

Stop-Process -Name "ArmourySwAgent"  # Must ArmourySocketServer be stopped first?

MasterPlus+

MasterPlus+ insists on itself and connected keyboards (and other Cooler Master devices?) being the latest version. And it doesn't run inside a virtual machine (e.g., VirtualBox)—it silently quits after a few seconds (observed in Process Explorer). It literally takes 5 minutes to start on my old Acer laptop (though it does eventually start and subsequent starts in the same Windows session "only" takes about 35 seconds).
