Introduction

In this article, we will be taking a closer look at the ASA Tech 645 LT liquid cooler and its performance in small form factor builds. We will discuss the improvements made in the redesigned version and compare its thermal performance to the previous model, as well as larger coolers. Additionally, we will explore the ease of installation in the Den A4 case and analyze the trade-off between case size and CPU thermal performance. Finally, we will highlight the impressive performance of the 645 LT and suggest other compatible cases for this liquid cooler.

Overview of the ASA Tech 645 LT Liquid Cooler

The ASA Tech 645 LT is a powerful 92 mm liquid cooler specifically designed for small form factor builds. It is the successor to the popular 545 LC model, with several enhancements and upgrades. The Pump block cover has been redesigned to have more character and a premium look. It now features HD Tech's Gen 6 pump, which is the latest pump revision and offers improved performance. The addition of sound dampening foam under the pump cover reduces noise, making the cooler even more appealing.

Changes and Improvements from the Previous Model

One of the significant changes in the 645 LT is the longer tubing, which provides more flexibility during installation. This allows users to route the tubing freely without bulging out of the case. The mounting bracket now locks into the pump block, enhancing the overall premium feel and ease of use. However, the most notable improvement is the addition of rotatable 90-degree fittings on the radiator. This change makes it easier to fit the cooler in compact cases like the Den A4, as the fittings can now be positioned to accommodate the limited space underneath the power supply.

Comparison of Thermal Performance

When comparing the thermal performance of the ASA Tech 645 LT to the previous 545 LC model, we see a modest improvement of 2.8 degrees Celsius in favor of the new cooler. This improvement can be attributed to the new pump design. However, it is important to note that the 645 LT runs about 4 degrees warmer than a 120 mm AIO liquid cooler, 12 degrees warmer than a 240 mm AIO, and 16 degrees warmer than a 280 mm AIO. This is expected, as larger liquid coolers require larger cases for installation. Therefore, the 645 LT offers a trade-off between case size and CPU thermal performance.

Ease of Installation in the Den A4

In the previous model, the installation process in the Den A4 case was challenging due to the tubing. However, with the 645 LT, the tubing can now be routed more freely, simplifying the installation process. The previous issues of bulging tubing and difficulty in closing the side panels have been resolved. While the installation process is still more involved than larger cases, it is significantly improved with the 645 LT. The only remaining concern is the clearance for the 24-Pin motherboard cable, which may require some maneuvering to fit properly.

The Trade-off Between Case Size and CPU Thermal Performance

The ASA Tech 645 LT offers impressive thermal performance for its size, but it is essential to consider the trade-off between case size and CPU thermal performance. This liquid cooler is capable of handling Ryzen 7 and Core i7 processors in small form factor cases like the Den A4, but it runs warmer than larger liquid coolers. However, if portability and compactness are important factors for your build, the 645 LT provides a viable solution. If you prefer a slightly larger case, the N case M1 is another excellent option that can accommodate a 240 mm AIO without sacrificing performance.

Impressive Performance of the 645 LT

Considering the constraints of small form factor cases, the performance of the ASA Tech 645 LT is commendable. The thermal improvement from the previous model and its ability to handle Ryzen 7 and Core i7 processors make it a compelling choice for compact builds. While it may not match the thermal performance of larger liquid coolers, it offers a significant upgrade over air coolers and provides better overclocking potential. The inclusion of the latest pump design and the use of rotatable fittings further enhance its appeal.

Other Compatible Cases for the 645 LT

Although the Den A4 is currently the most compatible case for the ASA Tech 645 LT, it is expected that more cases will come to market that can utilize this liquid cooler. As small form factor builds gain popularity, manufacturers like ASA Tech are investing in research and development to improve cooling solutions for this niche market. If the Den A4 is too small for your needs, the N case M1 is an excellent alternative that offers similar compatibility and performance. Both cases provide portability and optimize the use of the 645 LT.

Conclusion

The ASA Tech 645 LT liquid cooler offers an efficient cooling solution for small form factor builds. With its redesigned features and improved thermal performance, it provides an appealing option for users looking to minimize their case size without compromising on CPU cooling. The ease of installation and compatibility with cases like the Den A4 and N case M1 make it a versatile choice for various compact builds. Overall, the ASA Tech 645 LT is a welcome addition to the market, catering to the growing demand for high-performance cooling solutions in small form factor PCs.
