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.

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. 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:

Cooling loads of up to 315W, DeepCool’s LT720 provides the strongest cooling performance we’ve seen yet when paired with Intel’s i9-13900K.

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: This new architecture will have a direct impact on the appearance of the CPU, as Alder Lake features an most notably is no longer square, but rectangular. While this new generation of Intel CPUs promises even 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 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. Installation

You Require Low Noise: It has a fairly high overall noise output, so may not be suitable for users prioritizing a quieter system. 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. 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. I'll be testing DeepCool’s LS520 with Intel's i9-12900K. Due to the increased thermal density of the Intel 7 manufacturing process, as well as changes to core and component layouts, Alder Lake CPUs are more difficult to cool than previous generation CPUs in the most heat-intensive of workloads.
