Manufacturer description

The Thermalright Peerless Assassin 120 SE V2 is a dual-tower CPU air cooler for mainstream AMD AM4/AM5 and Intel LGA1851/LGA1700 desktop builds. Six 6mm heat pipes run from a nickel-plated C1100 pure copper base into two aluminum towers. Together they move heat away from your processor during gaming, multitasking and other sustained high-load work. The V2 update comes with two TL-C12C-X28 V2 fans. Each is 120 x 120 x 28mm, spins up to 1850 RPM (plus or minus 10%) and moves up to 88.89 CFM, with a maximum static pressure of 2.21 mm H2O. Thermalright rates their noise at 29.5 dBA. Because both…

Frequently Asked Questions

Which CPU sockets does the Peerless Assassin 120 SE V2 support?

The listing names AMD AM4 and AM5 and Intel LGA1851 and LGA1700. No other sockets are listed, so check with Thermalright before using it on an older platform.

How tall is this cooler, and will it fit in my case?

Without fans, the heatsink measures 155mm tall, 125mm long and 110mm wide. Compare the 155mm height with your case's maximum CPU cooler height, and check clearance around tall RAM modules.

How loud are the fans?

Each TL-C12C-X28 V2 fan is rated at 29.5 dBA and reaches up to 1850 RPM. They use 4-pin PWM, so you can set a fan curve in your BIOS that keeps them slower and quieter at light loads.

How do the fans connect, and how much power do they draw?

Each fan has a 4-pin PWM connector and is rated at 0.30 A. If you run both fans from one motherboard header, make sure that header is rated for the combined current.

What warranty comes with the Thermalright Peerless Assassin 120 SE V2?

The product listing doesn't state warranty terms. Check the current product listing or Thermalright's support site for coverage details before you buy.
