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. 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 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. 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.
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 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. will be more powerful than previous generations through the use of high-performance efficient cores. The 240mm liquid cooler comes in a box that uses molded cardboard, foam, and plastic for the protection of the inner contents.
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. 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.
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
