This article covers PCCOOLER 液体冷凍庫 DE360 MAX BK.

Overview

The PCCOOLER Liquid Freezer DE360 MAX BK is a 360mm all-in-one liquid CPU cooler designed for demanding builds. Its key differentiator is a 38mm-thick radiator, paired with three P12 PRO fans capable of up to 3000 RPM and 77 CFM airflow. The pump unit includes an integrated VRM cooling fan, and the package comes with a contact frame for Intel LGA1851 and LGA1700 sockets to optimize mounting pressure.
Cable management is simplified: the fan PWM cables route through the tube sleeve, leaving only one visible cable to connect to the motherboard. This makes for a cleaner build, especially in tight cases where multiple fan cables can become a mess.

Compatibility Guide

Socket support covers Intel LGA1851, LGA1700, LGA1200, LGA115x, and AMD AM5, AM4. The included contact frame is specifically for LGA1700/1851 and helps prevent CPU warping while improving thermal transfer. For AMD, standard offset mounting is supported to position the cold plate directly over the chiplet hotspot.
The radiator dimensions are about 400mm x 120mm x 38mm (Length x Width x Height). You need a case that can accommodate a 360mm radiator with at least 63mm of total thickness (38mm rad + 25mm fans). Most mid-tower and full-tower cases with top or front 360mm mounts will work, but clearance to the motherboard VRM heatsinks and memory modules must be checked. Pump height (including the VRM fan) should also be verified.
All three fans and the pump use standard 4-pin PWM headers. Ensure your motherboard has enough PWM fan headers, or plan to use a fan hub.

Product Info

Released in early 2025, the DE360 MAX BK is priced around ¥12,000–¥13,000 in Japan, making it a competitive option among thick-radiator 360mm AIOs. The warranty is typically 3 years (confirm with retailer). Market positioning is upper-mid-range to high-end: it can handle CPUs like the Core i7-14700K or Ryzen 7 7800X3D with headroom, and even Core i9-14900K under sustained loads, though that pushes the limits.
Integrated VRM fan (small PWM fan attached to the pump) actively cools the motherboard voltage regulators, which benefits overclockers or systems with high power draw.

Best Use Cases

  • High-end gaming builds with Intel Core i9 or Ryzen 9: The thick radiator and high-speed fans keep temperatures in check during extended gaming sessions. However, case compatibility is paramount – you need a case like Fractal Torrent or Lian Li Lancool III that supports thick 360mm rads. Not for compact cases.
  • Enthusiasts who prioritize cooling performance over absolute silence: The P12 PRO fans can spin up to 3000 RPM, which is audible under load. If you want a near-silent system, consider a 280mm AIO with slower fans or a custom loop. But if you want to overclock aggressively, this cooler delivers.
  • Builders who appreciate clean cable management: The integrated fan cable routing means fewer loose cables in the case. Great for showcase builds with glass panels. The single PWM cable approach simplifies connection.
  • LGA1700/LGA1851 platform users: The contact frame reduces CPU bending and improves thermal interface. If you've experienced hot issues with these sockets, this cooler's bundled frame is a nice bonus.

Things to Consider

The physical size is the biggest limitation. With a 38mm radiator and 25mm fans, total sandwich thickness is about 63mm. Many cases list support for 360mm radiators but only up to 30-35mm thick – always verify the actual clearance in your case. Also the radiator length (400mm) may conflict with front-mounted PSU cages in shorter cases.
Competitors: ARCTIC Liquid Freezer III 360 has a similar 38mm rad but often costs a bit less and has better pump reputation. Corsair H150i Elite offers better RGB and software control but higher cost. The DE360 MAX BK lacks RGB, which could be a pro or con depending on your aesthetic.
Fan noise at max RPM is noticeable (up to ~40 dBA estimated). You'll want to set a reasonable fan curve. Also, long-term reliability data for this newer cooler is limited – check user reviews for pump noise or leak reports before buying.

FAQ

Q: Does it come with thermal paste pre-applied?
A: Yes, a small tube of thermal compound is included. You can also use your own paste. The cold plate has a pre-applied thermal pad? No, it's a standard copper cold plate; apply paste manually.
Q: Can I replace the fans with Noctua or other static-pressure fans?
A: The fans use standard 120mm 4-pin PWM connections, so you can swap them. However, the thick radiator benefits from high static pressure fans; the stock P12 PRO fans are tuned for this radiator. Third-party fans may not reach the same pressure.
Q: Will the VRM fan interfere with tall RAM heatsinks?
A: The VRM fan is located on the pump housing, not directly over the RAM slots. But in some motherboard layouts, the fan overhang might block the first RAM slot if the memory modules are exceptionally tall (over 45mm). Standard-height DDR5 m
