Which one should you choose?
Choose Thermalright 53mm Low Profile ITX CPU Cooler if
- You need support for the newest LGA1851 socket.
- You want a cooler with a verified lower noise output.
- You have 53mm of clearance height in your case.
Choose ID-COOLING 45mm Low-Profile CPU Cooler if
- You have only 45mm of clearance height.
- You prioritize maximum airflow capacity.
- You are building a very tight HTPC setup.
Verdict: The Thermalright AXP90-X53 offers broader socket support and quieter operation, making it a versatile choice for standard ITX builds. The ID-COOLING IS-40X V3 is the better option if your case height is strictly limited to 45mm. Choose the Thermalright for better acoustic performance and the ID-COOLING for maximum compactness.
Thermalright vs ID-COOLING Low Profile Specs
Cooler Height
The Thermalright AXP90-X53 measures 53mm in total height, while the ID-COOLING IS-40X V3 is slightly shorter at 45mm. Both designs fall into the low-profile category, making them suitable for compact ITX cases and HTPC builds. The ID-COOLING unit offers a more compact vertical footprint, which can be critical if your case has extremely tight clearance constraints above the CPU socket. However, the Thermalright model provides a bit more height for its heatsink block, potentially allowing for slightly larger fin arrays. You should measure your specific case clearance carefully, as that 8mm difference may or may not impact your build depending on your chassis dimensions.
Heat Pipes
Both coolers utilize four copper heat pipes to transfer heat from the CPU base to the fins. The Thermalright AXP90-X53 specifies that these pipes are 6mm in diameter and employ AGHP (Advanced Gravity Heat Pipe) technology. This technique is designed to solve inverse gravity effects, ensuring consistent cooling performance regardless of whether the cooler is mounted vertically or horizontally. The ID-COOLING IS-40X V3 also lists four heat pipes but does not provide specific diameter or technology details in the available data. For both units, the four-pipe configuration is standard for this class of low-profile coolers, aiming to handle moderate thermal loads efficiently within the constrained form factor.
Fan Airflow
Each cooler includes a 92mm PWM fan, but their maximum airflow specifications differ. The Thermalright AXP90-X53 is paired with a TL-9015 fan that delivers a maximum airflow of 42.58 CFM. In contrast, the ID-COOLING IS-40X V3 features an upgraded 92mm PWM fan with a stated maximum airflow of 46 CFM. This gives the ID-COOLING unit a slight advantage in raw air movement, which can help dissipate heat more quickly under load. The Thermalright fan does specify an air pressure of 1.33 mmH2O, which aids in pushing air through dense fins. You should consider whether higher airflow or higher static pressure is more beneficial for your specific case airflow dynamics.
Fan Noise
Noise levels are a key consideration for quiet builds. The Thermalright AXP90-X53 fan has a maximum noise rating of 22.4 dB(A). The ID-COOLING IS-40X V3 fan has a maximum noise rating of 35.2 dB(A). This represents a significant difference in acoustic performance, with the Thermalright model being substantially quieter at its maximum speed. The ID-COOLING unit is described as low-noise, but the spec sheet indicates it can reach higher decibel levels. If you are building a system for a silent environment or a bedroom HTPC, the Thermalright cooler offers a much more peaceful operation profile based on these published specifications.
Socket Compatibility
Both coolers support a wide range of modern CPU sockets. The Thermalright AXP90-X53 supports Intel LGA1150, 1151, 1155, 1156, 1200, 1700, and 1851, as well as AMD AM4 and AM5. The ID-COOLING IS-40X V3 supports Intel LGA1700, 1200, 1151, 1150, 1155, and 1156, along with AMD AM5 and AM4. The Thermalright model explicitly lists support for the newer Intel LGA1851 socket, which the ID-COOLING data does not confirm. Both cover the essential current-generation platforms. If you are using the latest Intel 14th or 15th generation processors on LGA1851, the Thermalright cooler is the confirmed compatible choice based on the provided specifications.
Which low profile cooler suits your build
User with tight RAM clearance needs
The ID-COOLING IS-40X V3 measures 45mm in height. This extra compactness provides superior memory compatibility on small form factor motherboards. You can install tall RAM sticks without interference. The 92mm PWM fan maintains quiet operation at 35.2dB. Four heat pipes ensure adequate heat transfer for your CPU within this slim profile.
User prioritizing maximum airflow performance
The Thermalright AXP90-X53 offers higher airflow at 42.58 CFM compared to the ID-COOLING model. It also generates less noise at 22.4dB. The AGHP heat pipe technique helps manage heat more efficiently. You get better cooling performance with lower sound output. This makes it ideal for compact cases where quiet operation matters.
User needing broad socket support
The Thermalright cooler supports the latest Intel LGA1851 socket in addition to older standards. It also covers AMD AM4 and AM5 platforms. This wide compatibility ensures you can use it across multiple system generations. The included metal mounting fasteners simplify installation on various motherboard types. You do not need to worry about future CPU upgrades.
