Why Buyers Choose It
- The listed socket support covers several Intel and AMD platforms, which makes it easier to match the cooler to the correct board and CPU.
- The 118 mm cooler height gives a clear size check for case fit and surrounding components.
- The separate 4-pin fan and 3-pin ARGB connectors mean both cooling and lighting connections need to be planned on the motherboard.
- The quoted fan speed, airflow and noise level give a basic performance reference for comparing against other coolers.
How It Works
The cooler uses a 92mm PWM fan mounted on the heatsink. The fan has a 4-pin power connector, while the ARGB lighting uses a separate 3-pin connector that synchronises with a 5V 3-pin motherboard header.
The package also mentions an Intel backplate selection for the 17XX and 115X platforms, plus mounting plates or fasteners for different CPU socket platforms.
Real World Use
In a desktop build, this cooler needs enough space for its 94 x 77 x 118 mm footprint and the right socket hardware for the chosen Intel or AMD platform. Buyers should also confirm that the motherboard offers the required fan and ARGB headers if they want both functions connected.
What To Know Before You Buy
Check the CPU socket carefully before ordering, especially if you are choosing between Intel LGA1700, 1150, 1151, 1155, 1156 or 1200, or AMD AM4 and AM5. Review the cooler height and your case clearance, and make sure your motherboard has the required 4-pin fan connection and 3-pin 5V ARGB header if you want lighting synchronisation.
The cooler is listed as AX90 SE ARGB and as Thermalright Assassin X 90 SE ARGB, so the exact variation should be reviewed against your build plan.
