DeepCool does not warrant that this product will meet customer's requirements. It is customer's responsibility to determine the suitability of this product. When restricted to 200W, the LT720 kept Intel’s i9-13900K CPU at 52c over the ambient room temperature. This is a better thermal result than you’ll see from any air cooler, and it is in line with most liquid coolers on the market that I’ve tested – where I’ve seen a range of 49-52C over ambient. Given the very similar results in liquid coolers here, I’ll likely add 250W testing in the future to better show the performance differences of liquid coolers. In addition to testing Cinebench without power limits enforced, we’ll also be showing results when the CPU’s power consumption is limited to a more reasonable 200W. We’ll also show results at 125W for those who prefer whisper-quiet cooling, at the cost of some performance. For both of these results, we’ll show traditional delta over ambient temperature results. We are thankful to DeepCool for providing the testing unit. Awards Received By The Deepcool LT520 Cooler 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.

You Prefer Easy Installation: The cooler offers installation with 14 components for AMD CPUs, suitable for users valuing straightforward setup. Don’t Buy It If: While it was fairly easy with previous generations of CPUs for coolers to keep the flagship i9 processor well under TJ max (the maximum temperature a CPU can sustain without throttling) in tough workloads, this is no longer realistically possible on current generation CPUs (and the 13900K especially) without extreme cooling (or enabling power limits). One thing I like about DeepCool’s fans is that they have indicators showing the direction the fans spin and the direction of the airflow – this makes it easy for a person new to building PCs to know which direction the fans should be installed. Fan Model 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. Conclusion

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.

Oct 18th 2023 Lian Li Introduces Premium CPU Coolers Powered by Asetek's Most Advanced Liquid Cooling Technology to Date (4) 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.

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. Tier 2: These coolers are able to keep the i9-12900K under the TJ max threshold with CPU power limits of 200W enforced. I expect most liquid coolers and the best air coolers to meet this standard. Tier 3: These coolers are able to keep the i9-12900K under TJ max with CPU power limits of 140W enforced. Testing Methodology 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.

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. We recorded 50 dB(A) noise output from these fans at an ambient of 32 dB(A). The fans are loud at full speed and I would suggest PWM Auto control or custom fan curve. Should You Buy It?

DeepCool has certainly been on a bit of a busy release streak recently when it has come to brand-new cooling products. In terms of air coolers, we’ve seen models such as the AK400 ( review link here) and the AK500 ( review link here) which both impressed us massively! – This time around, however, it’s time to take something of a technological upgrade as we take a closer look at the newly released LT520 AIO liquid cooler! DeepCool LT520 AIO Liquid Cooler will be more powerful than previous generations through the use of high-performance efficient cores. Unauthorized repairs to a DeepCool product will void the coverage offered by the warranty policy. DeepCool reserves the right to refuse to service any product which has been altered, modified or repaired by non-DeepCool service personnel.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. You Require Low Noise: It has a fairly high overall noise output, so may not be suitable for users prioritizing a quieter system. Tier 1: These coolers are able to keep the i9-12900K below TJ max in most loads, with no power limits enforced. I expect only the best liquid coolers to meet this standard. 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).

There is no dedicated A-RGB controller provided with the cooler. There is no hub provided with the cooler either. The terminal connectors are 4-pin PWM and 3-pin, 5V, and A-RGB ones. The A-RGB lighting is compatible with: most notably is no longer square, but rectangular. While this new generation of Intel CPUs promises evenmore performance, not every compatible cooler available has the LGA1700 mounting hardware included in While this unit does have an accessible refill port, DeepCool advises to send it to them if refill or repair is necessary. With this unit’s 5-year warranty, you’re covered in the unlikely event occurs where service is required.
