To test the limits of a cooler's thermal dissipation capabilities, I run two primary stress tests: Cinebench and OCCT each for 10 minutes. While this may be a short amount of time, it is sufficient to push most coolers–air and liquid–to their limits. The increased cooling challenges posed by Raptor Lake mean that we’ve had to change some of the ways we test coolers. Some coolers were able to pass Cinebench R23 multicore testing with Intel’s 12th Gen i9-12900K when power limits were removed (although only the strongest models were able to pass that test). Most liquid coolers and all air coolers I’ve tested “failed” that test because the CPU reached TJ max in this scenario. This means that coolers that kept previous generation products like the i9-10900K nice and cool sometimes struggle to keep Intel's i9-12900K under Tj max–the top temperature before the CPU starts to throttle. Many coolers, including DeepCool’s last generation CASTLE EX AIOs, failed to keep the i9-12900K under TJ max when power limits are removed in workloads like Cinebench and OCCT when I’ve tested them. The LT series AIO coolers support most major RGB synchronization software to coordinate your colors and control different lighting effect to match personalize your system. The cooler is an AIO and has no clearance issue for the RAM and PCIe slot. However, make sure that your case supports 240mm AIO. The dimension of the radiator without fans is 282x120x27mm (LxWxH). With fans, the dimension is 282x120x53mm (height is increased). Performance Benchmarks

This is also the lowest TDP level I test at this power level, many coolers will run so quietly I’d have to disable my system fans to get lower noise readings. While most AIOs on the market are based on Asetek designs, DeepCool’s AIOs use a 4th generation pump designed in house by DeepCool. It utilizes a 3-phase drive motor which runs at up to 3100RPM, and features an improved microchannel design for better coolant flow vs previous generation products.

The sturdy frame and fluid dynamic bearings offer stable and long-term reliability. The FK120 fans included feature a dynamic PWM range than their retail counterparts. The Fluid Dynamic Bearing design provides dynamic PWM range, supreme airflow, near silent operation at ≤32.9 dB(A) full load noise, and 50,000 hours of long operational lifespan.

While this unit does have an accessible refill port, DeepCool advises to send it to them if refill or repair is necessary.

Installation While stress testing in Cinebench, I run both with power limits removed and with an enforced 200W CPU power limit. In this test setup using MSI’s z690 A Pro DDR4 Motherboard and Be Quiet’s Silent Base 802 Computer Case. Only the best coolers are able to pass Cinebench testing when power limits are removed.more performance, not every compatible cooler available has the LGA1700 mounting hardware included in In terms of total wattage this liquid cooler can handle, DeepCool’s LT520 shows the strength of their 4th generation pump design – handling 288W (on average) during the course of the Cinebench testing. This is similar performance to BeQuiet’s and Enermax’ offerings of this size class, and even 360mm models from Arctic & MSI that I’ve tested on Tom’s Hardware ( see results here). With a total system noise level of 43.4 dBA, the LT520’s noise levels aren’t quite what I would consider “silent”, but it doesn’t run loud in any sense of the word at all.

DeepCool does not warrant that this product will meet customer's requirements. It is customer's responsibility to determine the suitability of this product. While in the past a CPU hitting its peak temperature was cause for concern, enthusiasts are going to have to learn to accept high temperatures as “normal” while running demanding workloads with Raptor Lake and Ryzen 7000 CPUs. Modern AMD & Intel CPUs are designed to run fairly hot without any problems – up to 95 degrees C for AMD Ryzen 7000 CPUs, and up to 100 degrees C for Intel’s Core i9-13900K. Similar behavior has been standard in laptops for years due to cooling limitations in tight spaces.

Dropping the power consumption of the CPU causes the noise of the LT520’s fans to drop ~5 dBA vs full speed noise levels, bring the noise measurement down to 48 dBA.
