  • Outstanding cooling for a Ryzen 5 3600x even in an very hot room
Style: Ninja 5
TL;DR: Below is a very detailed review. The cooler is completely silent even set at max speed (800 rpm). It lowered a Ryzen 5 3600x temps by about 10°C in both "idle/low usage" and max load, despite a potentially incorrect thermal paste application (might've used too much). This cooler is a keeper for a 3600x. Check the tip on "3) Installation:" on this review if you're having issues with the metallic clips of the fans. 1) The situation: My room tends to be extremely hot during summer (on average over 30°C) and I was concerned that the stock cooler wouldn't be enough. And my concerns were verified quickly after summer really got hot. When I was gaming on a hot afternoon (around 32-34°C in my room), CPU reached 87°C. I definitely needed an upgrade in order to avoid throttling and also potentially damaging my PC over time. On top of that, the old stock cooler used to loudly increase and decrease speeds whenever the processor used more power/increased frequency, which is pretty much always when you got from not moving the cursor to doing anything on the PC. If I set it to full speed, it was too noisy too, so that wasn't an option. 2) The fix: After installing the the Ninja 5 cooler, temps decreased about 10°C. And I can set it to 100% fan speed (800 RPM) while making close to 0 noise. In fact, the most noisy fans currently are the ones on top of my case. But the annoying noise described earlier is gone thanks to the constant speed in the Ninja 5 fans. 3) Installation: Installation was sort of easy. They include everything you need, even a magnetic tip screwdriver. I had problems getting the fans in the metallic cooler. I hadn't installed a CPU cooler with detached fans in years. The manual wasn't quite clear (it's just pics) so I had to google how to properly clip the fans to the cooler. Also, don't forget to remove the plastic sticker that covers the base of the cooler. Do it as soon as you're going to install. I almost forgot. Pics show the cooler in a Aerocool One Eclipse case. It's certainly much bigger when compared to the stock Wraith Spire cooler. There's plenty of vertical room fortunately, so putting the glass lid on later wasn't an issue. However, the fans don't align with the exhaust fan in the case. Dunno if that's common or not. Tip: Follow the manual and make the clips get inside the fan holes. That much is easy to follow on the manual. Then you gotta pull on that "bent part" of the clip towards the metallic indentation on the cooler and "clip" it there. Yes, you gotta apply force towards the cooler (or away from the fans basically) while holding the fan with one hand. Don't worry, the things won't break. They're more bendy than expected. Check the pic I added at the end, that's where the clips get in. 4) The tests: The graphs in this review were generated with CPUID HWMonitorPro, and were done under the following parameters: a) Prime95 running a small FFTs test, 15 ±2°C room temp, AMD Wraith Spire Cooler (pre-applied thermal paste). b) Prime95 running a small FFTs test, 18 ±2°C room temp, Scythe Ninja 5 (Thermal Grizzly Kryonaut thermal paste) Note: the room temps are lower than 30°C because I ran the tests at night, not during the day. Important: I did not use the included thermal paste in the box. I applied the one mentioned above, with the included spatula. I never had done it that way, and I was experimenting, so I might've miscalculated the amount and used too much. Temps could be even slightly lower if I re-applied but with less paste. 5) The results: a) Max temp was 94,5°C at node 0 (red line). It took less than 1 minute to get there, which made me shutdown the test otherwise I was risking damage to the processor. Max wattage reached to about 95 watts. b) Max temp was ~84,3°C at node 0. It didn't go past that temperature during the 4 minutes I ran the test. Note that my room was also about 3 degrees hotter than in the first test, so in theory you could take 3 degrees off that. Also note that the max wattage reached around 108 watts. That's 13 more watts of power that the processor was being fed and despite that the temps didn't get close to 90°C 6) Test conclusions: A 10-13°C temperature reduction on max load. Higher power consumption with the Ninja 5 cooler (meaning that the CPU wasn't throttling itself). Completely silent at 800 max rpm. I'm 100% satisfied with it. I don't think this fans has any cons at the price point and performance. 7) Some clarification: For those that don't know what Prime95 is: it's a program that stresses the processor doing several calculations in parallel. It produces a lot of heat in the process, which is pretty useful for testing how effective the cooling is and if the clock speed/voltage is stable. The black dotted line (Package): it's a built-in offset in AMD Ryzen processors. I don't really know the purpose of it, but it tends to over-report temps based on what I read online. Might be a built in safety protocol to throttle the processor if the temps are too high. That's it! Thank you for reading. I hope what I wrote was useful to you :) ... show more

  • Great Silent Performance
Style: Ninja 5
This review is purely about the install, there are plenty of performance metrics to look at online already. The short of it: this cooler does the job, and it does it extremely quietly. I was initially skeptical about various aspects of this cooler, from wondering if it would fit in my build at all to wondering how it could possibly be an efficient and nearly silent cooler for only $60 USD. Somehow, this cooler really does manage to do it all, and at a very appreciable price. First off, my package was shipped with UPS. They really did a number on the box. The Prime tape was completely ripped off one side, one corner of the box was pushed in, and it just generally looks like it got certifiably yeeted several times in handling. However, the inner package was completely fine and extremely well packed, there was no damage to the product at all. Installation is relatively straightforward, though it can vary slightly based on your motherboard design. I installed this on an ASUS Prime x570-Pro. I just had to remove the stock cooler brackets, install Scythe's brackets, apply the thermal paste that Scythe provided with the cooler to the CPU, drop down the cooler, and screw in. Bonus, this cooler comes packed with a long, small handled, and surprisingly high quality screwdriver, as the mounting screws must be accessed through the deep cutouts on the massive heatsink. Next, the fans use fan clips to attach to the heatsink and I found these to be a bit cumbersome on the install, though they do feel secure once finally attached. If there is any room for improvement here, it would be in the fan mounts. They just don't feel good to use and they look a bit wonky, all things considered. For $60 though, and considering how closely you'd have to be inspecting the finished build for them to stick out, I think this is perfectly acceptable. This cooler also comes with a 2 fan connection cable, so both fans may be plugged into one CPU Fan header. Finally, the size needs to be talked about. This thing is huge. If that's what you're going for, great. Make sure you know your measurements and will be able to fit this monster into your system! Using Corsair LPX Vengeance RAM, an ASUS Prime x570-Pro mobo, and the CoolerMaster H500 case, I was able to fit this no problem. It is VERY tight on space however. It's worth considering your necessary PSU connections before installing the motherboard with this cooler on it, as I spent 15 minutes just trying to connect cables to the top left of my board through a tiny open slot between the cooler and the top of my case. All in all, if you've got the space and you don't want to deal with the hassle, upkeep, and potential breakpoints of water coolers, this is a great choice by itself. Paired with the relatively low price point, this might be the single highest value CPU air cooler on the market right now. ... show more
