How to Choose a Thermalright LGA 1700 Cooler
-
Check the Heat Pipe Count
Heat pipes transfer thermal energy directly away from the processor base plate into the aluminum cooling fins. Thermalright models on this list feature configurations ranging from four up to six copper heat pipes. If you run a standard mid-range desktop CPU, a setup with five pipes, such as the Thermalright Assassin King 120 SE CPU Cooler, provides 235 W of thermal capacity. For higher thermal loads, coolers equipped with six heat pipes maximize heat distribution across the fin stack.
-
Evaluate Tower Design Clearance
Tower design dictates motherboard layout clearance and internal case volume requirements. Dual-tower configurations offer larger fin surface area and dual 120 mm fans, but they occupy significant space around memory slots and motherboard heatsinks. In contrast, single-tower models preserve clearance around your components while maintaining strong thermal transfer. The Thermalright Burst Assassin 120 ARGB uses a single-tower design that fits within a 154 mm height profile. This format ensures surrounding motherboard spaces stay accessible without sacrificing six-pipe heat dissipation.
-
Measure Vertical Cooler Height
Vertical cooler height determines whether your chassis side panel can close properly. Standard tower designs range between 148 mm and 157 mm tall, requiring mid-tower or full-tower desktop enclosures. If you use a small-form-factor chassis, look at low-profile horizontal coolers instead. The Thermalright AXP120-X67 Low Profile Cooler stands at a 67 mm height while still mounting a full 120 mm slim fan and six heat pipes. Always verify your computer case specifications for maximum CPU cooler height before making a selection.
-
Decide on ARGB Lighting
Thermalright manufactures both non-illuminated and addressable RGB models across its LGA 1700 catalog. If you prefer a clean look without lighting, models like standard aluminum dual towers omit illumination entirely. If you want custom visual styling, select a cooler with integrated ARGB lighting. The Thermalright Assassin X 120 White ARGB combines ARGB fan illumination with a white finish, four heat pipes, and a 225 W maximum TDP rating. Confirm whether your setup requires ARGB lighting or standard non-lit cooling before you make your selection.
-
Verify Multi Socket Compatibility
Although you need LGA 1700 support today, checking broader socket compatibility protects your purchase for future motherboard upgrades. Many Thermalright coolers support multiple generations of hardware, including AMD AM4 and AM5 alongside Intel LGA 1200, LGA 1150, LGA 1151, and newer LGA 1851 sockets. For example, the Thermalright Peerless Assassin 120 Dual Fan Cooler includes hardware for AM4, AM5, LGA 1851, LGA 1700, and earlier Intel sockets. Choosing a model with extensive socket coverage ensures you can reuse your cooler across different builds over time.
-
Match Color and Material Finishes
Cooler materials and exterior colors allow you to match the visual theme of your internal PC components. Thermalright options include standard aluminum finishes, coated all-white designs, and specialized full-copper builds. If you build an all-white gaming rig, the Thermalright Peerless Assassin 120 White provides a white dual-tower aluminum build with 9600 cm² of surface area and noise levels capped at 25.6 dB(A). Choosing a matching finish ensures consistent styling across your motherboard, case, and cooling hardware without altering basic installation requirements.
Frequently asked questions
Which Thermalright cooler is best for a low-profile Mini-ITX build on LGA 1700?
The Thermalright 47mm Full Copper CPU Cooler is designed specifically for space-constrained mini-ITX enclosures. Its low-profile 47 mm overall height allows installation inside narrow cases where vertical clearance is limited. The cooler features four 6 mm heat pipes, an all-copper build, a slim 92 mm fan, and a dedicated metal backplate mounting system to maintain secure contact pressure on LGA 1700 sockets.
What is the height difference between the Peerless Assassin 120 and the Peerless Assassin 120 SE?
The standard Peerless Assassin 120 stands at 157 mm tall, whereas the Peerless Assassin 120 SE measures 155 mm. This 2 mm reduction helps the SE version fit into narrower mid-tower PC cases that have strict vertical CPU cooler limitations. Both designs feature dual cooling towers, six copper heat pipes, and two 120 mm fans that move up to 66.17 CFM of air.
How much thermal wattage can Thermalright single-tower LGA 1700 coolers handle?
Thermalright single-tower models provide between 225 W and 235 W of heat dissipation capacity. The Assassin X 120 White ARGB handles up to 225 W of processor heat using four heat pipes. For heavier workloads, the Assassin King 120 SE increases capacity to 235 W by utilizing five heat pipes across a compact 148 mm tall fin stack.
Are Thermalright LGA 1700 coolers compatible with next-generation Intel LGA 1851 motherboards?
Yes, multiple Thermalright LGA 1700 models explicitly include LGA 1851 socket compatibility in their specifications. Coolers such as the Peerless Assassin 120, Burst Assassin 120 ARGB, and AXP-90 X47 list mounting support for both socket types alongside older Intel sockets like LGA 1200 and LGA 1151. This shared hardware compatibility allows you to transition your cooler across platform upgrades.
How quiet are Thermalright dual-tower coolers during operation?
Thermalright dual-tower coolers operate at or below 26 dB(A). For example, the Peerless Assassin 120 SE carries a sub-26 dB(A) acoustic rating, while the Peerless Assassin 120 White caps noise levels at 25.6 dB(A). Their twin 120 mm PWM fans regulate operational speeds automatically, delivering high static pressure and airflow without generating disruptive fan whine inside standard desktop chassis.
What low-profile Thermalright cooler options exist above 50mm for LGA 1700?
The Thermalright AXP120-X67 series provides low-profile cooling at a total height of 67 mm. It features six heat pipes and uses a slim 120 mm fan rather than smaller 92 mm alternatives. This layout allows small-form-factor LGA 1700 systems with moderate vertical clearance to achieve broader heat distribution across a larger surface area than 47 mm ultra-compact coolers.
Does Thermalright offer single-tower coolers with six heat pipes for LGA 1700?
Yes, the Thermalright Burst Assassin 120 ARGB provides a six-pipe thermal configuration inside a single-tower format. Standing 154 mm tall, it routes heat through six copper heat pipes into a single aluminum fin stack. This configuration provides the thermal density typically found in larger dual towers while preserving clearance around motherboard VRM heatsinks and tall memory modules.
