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 Prefer Easy Installation: The cooler offers installation with 14 components for AMD CPUs, suitable for users valuing straightforward setup. Don’t Buy It If: 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). The 240mm liquid cooler comes in a box that uses molded cardboard, foam, and plastic for the protection of the inner contents.
will be more powerful than previous generations through the use of high-performance efficient cores. You Require Low Noise: It has a fairly high overall noise output, so may not be suitable for users prioritizing a quieter system. DeepCool does not warrant that this product will meet customer's requirements. It is customer's responsibility to determine the suitability of this product. 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. 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

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

With this unit’s 5-year warranty, you’re covered in the unlikely event occurs where service is required. Installation 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). Accident, abuse, misuse, neglect, fire, water, lightning, other acts of nature, electrical surge, commercial or industrial use, unauthorized product modification or failure to follow instructions included with the product.
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. 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. 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.
