I'm not sure why the difference is so little between PBO without OC and PBO+OC, I thought it should be higher, also voltages seem a bit high when using Auto OC so I disabled it after the tests (it reached over 1.4v) Deepcool AK620. This was a good contender, but Chinese company with dodgy rep. Still, I probably would have bought their upcoming cooler/redesigned existing line with big LCD screen atop the heat sink, but they've been faffing around for too long now. graphs while leveraging the AMD Ryzen 7 5800X, illustrating how each cooler performs under various varying CPU power levels. This allows for a clear comparison of their The fans are easy to mount, the metal clips don't require much force to stretch them over to the heatsink

I've been round the bend trying to find a cooler for the 7800X3D that meets the following criteria. 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. I say go for it, you may lose 1-3c but its not that big of a deal. I was running 1 fan on my cooler for a month or so, just to see how it dealt with summer. I have the front fan on right now, but I might take it off since I cant see my ram anymorebut i'd give it a couple weeks for info to come in before jumping in myself. let others be the guinea pigs and find out if something does not work :) Tier 3: These coolers are able to keep the i9-12900K under TJ max with CPU power limits of 140W enforced. Testing Methodology Due to requests from our readers, I’ve begun to include 95W results, which should be broadly applicable to CPUs like AMD’s Ryzen 5 5600V or Intel’s Core i5-12400. In these lower wattage tests, the Peerless Assassin once again lives up to its name, outperforming it’s nearest rival by six degrees C when fans ran at the default fan curve, and a whopping 12 degrees C when set to 50% fan speeds. While stress testing in Cinebench, I run both with power limits removed and with an enforced 200W CPU power limit, using MSI’s Z690 A Pro DDR4 Motherboard and Be Quiet’s Silent Base 802 Computer Case. Only the most capable coolers are able to pass Cinebench testing when power limits are removed.

In all workloads tested, the Peerless Assassin 120 SE ran very quietly. When running at maximum fan speeds, it is the second-quietest cooler we’ve tested thus far. At an enforced 50% fan speed, it runs quieter than all coolers we’ve tested except for Cooler Master & Corsair’s AIOs. Conclusion There should be more all-white any hardware in the market.Agreed. Don't care it's not inline w/ max thermal dissipation. It looks great, at least when it's clean. Phantom Spirit 120 SE aka PS120SE (7x 6mm heatpipes & 2x TL-C12B V2 fans) is same price range as Peer.ess Assassin SE aka PA120SE w/ 6x 6mm heatpipes & 2x TL-C12C fans). I'll be testing Thermalright’s Peerless Assassin 120 SE with Intel's Core 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.

i don't want to be the beta tester so i wait. but if you can handle working with any potential bugs and don't mind doing it, then early adoption is not the worst thing ever :) The Peerless Assassin 120 is a really impressive cooler. Solid fit/finish, Solid performance, It is quiet (not by much) vs the Freezer 34 eSports DUO and its price makes it a steal. From my testing, I think the fans are the weak link, especially if you want to push this cooler with higher ambient temps or higher thermal loads and don’t want them running at max RPM. I think a fan like the TL-B12 which is a very close match to the BioniX P120 on paper should be a solid upgrade. My plan will be to test out the BioniX P120s on the Thermalright. If they perform like I expect, I’ll be looking into a piar of TL-B12s to try out down the road. Sadly I doubt I can mess with my fans in the next few weeks, but I will post once I have some results. Too bad I'm no longer in the market for such items though, or I would probably be all over this cooler.

Difficult to increase sample size with multiple TH reviewers. Leaves me wondering about comparison to the Deepcool AS500 (or similar single-tower 140mm coolers, Scythe Fuma 2, etc.) Would be nice if testing can be normalized in a way that allows results to be transferred/combined for larger lists.

I was trying to find the differences between these two CPU coolers. The PA120 (non-SE) seems to be an earlier variant and 2mm (157mm) taller that the PA120 SE version (155mm). RichardtST said:Awesome. So it should work pretty well if I remove the fan covering the RAM? Or move it to the other side? Gotta have my pretty RGB RAM and cannot be covering it up! Mounting system looks like a breeze too. in the very limited couple days we've had with am5, i've not seen anything to say otherwise. everything i have seen says am4 coolers are compatible. Also from what I see now, the fans are noticable at 1200 RPM, but I just set my curve to never spin more than 1200 RPM then, because it cools too well even below 1200 RPM I thought about getting one of these heat sinks when I found out they were so much cheaper. Can the front fan be moved up higher away from the RAM if more clearance is needed?

With OCCT, Thermalright’s Peerless Assassin SE continued to deliver outstanding results. While it wasn’t able to pass 200W with reduced fan speeds in this scenario, at the default fan curve it averaged 64 degrees C over ambient – once again degrees C cooler than DeepCool’s AK500! CPU R7 1700 MotherboardAsus Prime X370 Pro RAM 24GB Corsair LPX 3000 (at 2933Mhz) GPUEVGA GTX1070 SC CasePhanteks Enthoo Pro M Thermalright installed two TL-C12B fans on the unit, which can spin at a speed of up to 1550 RPM, when they produce 25.6 dBA of noise, 66 CFM of airflow, and generate 1.53mm of static pressure. They feature an S-FDB bearing and can make use of PWM signals so you'll be able to run them quietly when needed. relative performance and sound output when under different heat loads. The comparison is conducted under the following conditions:I wasn't expecting much quality for the fans for the low price but the included fans are crazy good, almost Noctua level for air / low noise. OCCT’s CPU Test was run and HWInfo64 was used to log data for each execution. I then extracted out some key metrics and graphed them for easy review. My goal for the test was to generate heat in a straightforward, repeatable and controlled a manner with various CPU configurations. This means that coolers that kept previous-gen products like the i9-10900K nice and cool sometimes struggle to keep Intel's i9-12900K under Tj max–the maximum temperature before the CPU starts to throttle. Many coolers, air coolers in particular, fail to keep the i9-12900K under TJ max when power limits are removed in workloads like Cinebench and OCCT when I’ve tested them, including many coolers I previously considered top of the line. showcasing critical qualitative and performance metrics.
