Low-Profile Tames Mighty Core i9-12900K LGA1700 Cooler
Jonsbo’s HP400S will discharge up to 140W of power.
Jonsbo isn’t known as a household name in today’s world of coolers; however, the company has recently introduced what may be the best low-profile, high-performance solution to Intel’s latest 12th-generation Alder Lake processors. This device is intended to be used on small-form-factor (SFF) PCs and can deliver up to 140W of power to run the Core i9-12900K processor from Intel.
Jonsbo’s tiny HP400S cooling system is only 36 millimeters in height (as discovered through TechPowerUp). Yet, it is equipped with 40 aluminum fins and four heat pipes of 6 millimeters and a 90-mm PWM fan spinning at speeds of 800 x 3000 RPM plus 10% to create an airflow of up 48.3 CFM and wind pressure that can reach 3.24mm H2O. The fan’s noise can go as high as 33 dBA, which is not the most pleasant setting for the SFF desktop. Due to the high circulation of air, the cooler will chill CPUs to as high as 140W of TDP/PBP (processor base power).
The HP400S design from Jonsbo is specifically designed to give the most efficient performance within such a compact dimension.
For example, the slim profile NHL9i-17xx (which measures 37 millimeters tall) is equipped with just two heat pipes and a fan that can spin at 2500 RPM and produce airflow that can reach 33.9 CFM. Noctua usually does not provide TDP/PBP ratings. However, the NH-L9i-17xx comes with an NSP rating of 59, which is a sign of the performance of a basic model.
A 140W rating may not mean it will guarantee that Core i9-12900K can run at its turbo speed for an extended period (i.e., it will not have the same speed as coolers with higher performance). It should not overheat in a small computer.
Coolers with a low profile and low-profile designs typically aren’t built for high-performance CPUs. However, the current trend toward miniaturization requires hardware makers to design components that can accommodate the most powerful CPUs in mini-ITX or miniSTX chassis.
In addition to the LGA1700 CPUs, Jonsbo’s HP400S can also be used with AMD’s processors in AM4 packaging, as also Intel’s CPUs are with LGA115x or LGA1200 form-factors. However, the price of the cooling system is still unknown.
