Who it fits
Good fit for
You should choose this cooler if you have a mid-tower or full-tower case with at least 158mm of clearance. It is ideal for users with LGA1700, LGA1851, or AM5 processors who need strong cooling performance. The dual-tower design and six heat pipes handle significant thermal loads. If you prefer a clean, all-white aesthetic and do not require RGB lighting, this model fits your build. It also includes a Y-cable to simplify fan connections on motherboards with limited headers.
Who should skip it
Skip this option if your case has less than 158mm of CPU cooler clearance. The dual-tower design may block tall RAM modules, so check your memory height compatibility first. Users seeking RGB lighting or ARGB synchronization will find this model lacks those features. It is also not suitable for small form factor builds due to its size. If you need a cooler for a compact ITX case, look for a low-profile alternative instead.
Verdict: This is a solid, no-nonsense air cooler for standard ATX builds. It delivers strong cooling performance through its dual-tower design and six heat pipes.
Key specs for this cooler
Tower Design: Dual Towers
This design uses two separate fin stacks instead of one. You get more surface area for heat to escape. This helps when your CPU runs hot under heavy loads. It is better for high-performance tasks than single-tower models. Check your case to ensure it fits the wider width.
Heat Pipes: 6
Six copper pipes move heat from the base to the fins. More pipes usually mean faster heat transfer. This helps keep your CPU cool during gaming or rendering. It is a standard count for this performance class. Compare this with other coolers to see if they use fewer or more pipes for similar results.
Cooler Height: 158mm
The unit stands 158mm tall. You must check your case specifications to ensure it fits. This height may block tall RAM sticks. It is suitable for mid-tower and full-tower cases. Measure your available space before buying. Smaller cases might not accommodate this size.
Fan Speed: 1500rpm±10%
The fans spin at 1500 RPM with a small variance. This speed balances airflow and noise. It is quiet enough for daily use but still moves air effectively. You get consistent cooling without loud wind noise. Compare this to higher RPM fans which may be louder but offer more airflow.
Design and Build Quality
The listing describes a twin-tower heatsink constructed from all-aluminum fins. This material choice maximizes surface area for heat transfer. Six pure copper heat pipes connect the base to the fins. The base senses CPU temperature and disperses heat efficiently. This layout supports high-performance cooling for demanding workloads.
The unit measures 140 by 157 by 158 mm. You should check your case clearance because the 158 mm height may interfere with tall RAM modules. The cooler weighs 3.94 pounds. This weight requires a sturdy mounting system. The listing notes an all-metal fastener system with an SS2 buckle for secure attachment. This design simplifies installation across various sockets.
It includes dual PWM fans, specifically the TL-C12W V2 and TL-D14CW. These fans spin at 1500 RPM with an air volume of 66.17 CFM. The noise level stays at or below 25.6 dB. A Y-type adapter cable allows you to connect both fans to a single motherboard header. This helps if your board lacks enough fan ports. The white finish matches modern aesthetic builds. According to the listing, it supports Intel LGA1150 through 1851 and AMD AM4/AM5 sockets.
Installation and Daily Operation
Setting up the Thermalright Peerless Assassin 140 White requires careful attention to case dimensions. The cooler stands 158mm tall. You must verify that your PC chassis can accommodate this height without interference from RAM sticks or side panels. The unit supports a wide range of modern sockets. It fits Intel LGA 1150, 1151, 1200, 1700, and 1851. It also works with AMD AM4 and AM5 platforms. The mounting kit includes specific fasteners and plates for each socket type. This ensures a secure fit without needing additional tools.
The package includes a Y-type adapter cable. This cable connects the two fans in series. One end is 3-pin and the other is 4-pin. This feature helps if your motherboard lacks enough fan headers. It simplifies wiring by allowing you to use a single connector for both fans.
During daily use, the dual PWM fans operate at 1500 RPM. You can expect an airflow of 66.17 CFM. The noise level stays at or below 25.6 dB. This makes it suitable for quiet environments. The fans are 120mm and 140mm in size. They draw 12V power. The all-metal fasteners with the SS2 buckle system provide a stable connection. This design reduces vibration during operation. You get consistent cooling performance for heavy tasks. The dual tower design maximizes heat dissipation. It handles high thermal loads effectively. The white finish matches modern white-themed builds. Installation is straightforward if you follow the included tutorials. The cooler is ready for immediate use after mounting.
Before You Buy This Cooler
Before you buy, verify your PC case supports 158mm cooler height. Large cases usually fit this dual-tower design, but smaller mini-ITX boxes may not. Check RAM clearance too. High-profile memory sticks might block the fans or fins. The unit includes a Y-type adapter cable, so you can connect both fans to a single motherboard header. This helps if your board has limited fan ports. You need to ensure your CPU socket matches the supported list, including LGA 1700 or AM5. Keep the fins clean from dust to maintain airflow efficiency. This model offers strong cooling for its price point. It sits alongside other high-performance air coolers in the 1 options available. If you need quiet operation, note the noise rating is up to 25.6 dB. For most users, this cooler provides excellent thermal performance without requiring liquid cooling.
Check before you buy
- Check case height clearance for 158mm cooler
- Verify RAM sticks fit under the fans
- Confirm CPU socket compatibility with your board
- Ensure motherboard has enough fan headers
