Thermalright Peerless Assassin 120 SE CPU Cooler, 6 Heat Pipes AGHP Technology, Dual 120mm PWM Fans, 1550RPM Speed, for AMD:AM4 AM5/Intel LGA 1700/1150/1151/1200/1851,PC Cooler

When I built my PC five years ago I installed a Dark Rock Pro 4 for my CPU cooler. It worked very well, but over the years the fans grew louder, the cooling became less efficient, and dust began to accumulate in hard to clean places. I decided to look for an affordable replacement and settled on the Thermalright Peerless Assassin. Overall, I believe this was a very good choice. Compared to my Dark Rock Pro 4, the Thermalright Peerless Assassin was a breeze to install. The LGA 155x bracket fit my motherboard and was easy to install. The thermal paste seemed thicker than other pastes I've used, but it went on neatly and is clearly working. The spring screws seem to have secured the cooler to the brackets very well. My biggest complaint with my old cooler was installing the fans. Happily, I can report that the Peerless Assassin's fan are easy to install, and remove if needed, and are secure. In terms of performance, I'm completely satisfied. The fans are not as quiet as my Dark Rock Pro 4 when I first installed it. However, they are an acceptable low volume. My PC has an Intel Core i7-8700k CPU and the cooler has no problem keeping it between 20C to 30C while idle or under a light load. I am no longer an avid gamer, and do not play modern video games, however I did test the thermals while playing Minecraft. It kept my CPU around 40C most of the time and would briefly shoot up to 50C when loading parts of the map. At less than 40 USD this cooler is a fantastic option for CPU cooling. Its significantly less expensive than comparable coolers, is easy to install, and delivers good performance.

My Ibuypower water cooler failed on my system. (I discovered this is very common). I was debating on either getting a water cooler or going to Air cooling. I checked a lot of videos online and this air cooler kept coming up in the top 5 replacement recommendations over and over again. (search water coolers vs Air coolers) Since I don't do any overclocking and the fact that they are much more reliable, I bought this unit. It works really great. It cost so much less than a water cooler and (in my opinion) is easier to install that a water cooler unit with hoses and radiator and cpu block. Positives: Very Affordable Cools very well Very well made Package comes with everything you need. (different cpu socket mounts and thermal paste) Extremely reliable. (no worries about coolant leaks or pump failure or in my case, clogged lines) The fans that come with it seemed pretty quiet. (more than my cheap water cooler fans) Negatives: Can be a little difficult to install. The most difficult part was installing the fans. The instructions could be better. (they're not horrible). I do recommend watching online videos. Its big, you definitely need to make sure you have enough room in your case. Additional Recommendations: The thermal paste that comes with the package is ok, but I would highly recommend buying a high quality NON CONDUCTIVE thermal past. (Thermal Grizzly Kryonaut, Artic-mx4, Cooler Master MasterGel Pro v2 etc) This is important! Make sure its NONCONDUCTIVE. Some thermal paste uses metallic ingredients to aid in thermal conductivity. The problem with this is that if you apply too much, it can go into the cpu electronic components and damage your system. With noncoductive thermal paste, this isn't a issue so you don't really need to be too exact. (If its a little too much, it doesn't hurt anything.) This Air cooler also comes in single or double tower configurations, if your case can support it, I would definitely get the double tower. Make sure you get the fans installed/oriented correctly. I would also recommend installing cpu temperature monitoring software as well to make sure that everything is working correctly. I would definitely recommend this to anyone who wants a very reliable and very affordable air cooling option.

Upgraded my processor from a Ryzen 3900x 12 Core to the new 10th anniversary edition Ryzen 5800x3D and initially I decided to just reuse my cooler that I was using for my 3900x which was a Coolermaster Hyper 212 Black Edition. Boy was I in for a surprise when I was idling in the lower to mid 50's and maxing 91C running Cinebench tests on the 5800x3D. My 3900x was never running like that, though I could definitely feel warmth coming out of my tower all the time with my Coolermaster on my 3900x. After reading around the internet this one was recommended many times for the 5800x3D and decided for how cheap it was, got nothing to lose. Installation was actually easier than my Coolermaster with only having two screws to tighten versus 4 on my Coolermaster. Tightening them was a breeze, starting just a couple turns on one to get it threaded then going to the other one, do the same and just go back and forth until they're both snug, not overly tight. Had to raise the front fan a smidge due to my high-profile ram but it is what it is. After I got back up and running, I decided to go right back on Cinebench and run another multicore test, and to my surprise, the CPU only maxed at 81C for the whole test, with fluctuations between 78-80 most of the time. That's a great 10C drop in CPU temps from my last cooler. Also, my idling temps are now around 36-40C which is another roughly 10C drop. Also, the air coming out of my tower with this thing was pretty cool compared to my previous Coolermaster, even under heavy benching. The included fans were barely audible even during the Cinebench rendering. Like you could tell they ramped up if you were focused on it and really listened, but they were really quiet overall. No vibrations or weird noises like a lot of people complain about. I used Arctic MX-4 thermal paste instead of the included paste so I can't comment on how good it is. I think people tend to over exaggerate the size of this sometimes, but it is big, but not like anything that will stop you from putting it into a full-size tower. Overall, I'm more than happy and would easily recommend this for a 5800x3D on AM4.

I was skeptical, but this cooler is keeping my Ryzen 9 9900X cool. It is operating within normal temperature ranges. At max load it hit 170f (76c). Max temp for my processor is 203f (95c), so plenty of room. Installation was simple enough, use the included mounting hardware for your processor, apply paste, mount the heatsink, then clip the fans on the heatsink. What I really liked was not having to use screws with the fans. What isn't apparent until you look closer at the diagram is that one fan goes between the heatsinks and the other on the right side. Both fans point to the rear across the heatsinks (see the diagram as it is clear) where the hot air is pulled out by the rear case fan(s). The unit fits exactly as it should on the motherboard. The fans are quiet and do the job. The paste being used is Corsair XTM60, which I've had good results with both on other CPU and GPU (I repasted my old GTX 1070). The case I'm using is a Corsair 5000D, which I picked up as an open box at (the most popular computer retail store). I have three fans in the front pulling in air, two on the top above the motherboard pulling in air, and one exit fan in the rear. I may adjust the fan configuration later, but it is doing fine. Getting back to the cooler, I am pleasantly surprised with its performance. For the price you can't beat it, and it supports both Intel and AMD processors. It is a good product. I would definitely recommend it.

One of the best value CPU air coolers out there, a little unflattering but does the job well. I bought one originally for my sister for the Intel Core Ultra 5 265k and at light use it runs fairly cool 40-60. Now I do note that it runs fairly hot under full (100%) load 70-80 from what I remember. But I bought this for my Ryzen 9 5900 XT that I recently got, I'll update to see how hot it gets when I build it, oh and one final note the last 2 screws are kinda hard to get down on the first try but dont give up!. Cheers! Update: CPU Tested Ryzen 9 5900 XT After benchmarking I got it to reach ~3.6-3.7 GHZ sustained load for all 16 Cores @ ~62 C on stock settings pulling about 125 W. With limits set to motherboard and a -15 curve optimizer undervolt I got 4.3-4.4 GHZ sustained load @ 90 C pulling about 220 W

After getting my Ryzen 7 5800XT I was told emphatically that I *need* to use liquid cooling, there's *no possible way* an air cooler could keep it from melting. I really didn't want to spend that much and figure out how to mount it in my case, though, so a friend recommended this one to me, and I couldn't be happier. Keeps this notoriously hot CPU at just around 60C full load and 30~40C idle. It's big and kind of unwieldy, but I was able to fit it in a micro-ATX case just fine. You might need to remove it to change other parts, but it's not that hard to uninstall or reinstall. I do think the "fan clips" are really stupid though. I get they had to cut the cost somewhere to get this thing this cheap, but it feels a bit insane entrusting the fans to a glorified paperclip, and I could not for the life of me figure out how to actually get them properly clipped on to the heatsinks at first. Pretty quiet and reliable so far but I've only had it in the machine for a little bit, so I'll make sure to come back and edit this review if it craps out on me.

I absolutely love the Peerless Assassin. This cooler dropped my CPU temperatures by a significant amount, and I couldn’t be happier with the performance. Thermalright is, and has been, changing the game. From their AIOs to their fans and air coolers, they’re giving companies like Corsair and be quiet! a serious run for their money. The only negative I’ve found is that if you have taller RAM sticks, you’ll have to raise the front fan slightly to clear them. If Thermalright made the cooler about 5 mm taller, it would be nearly perfect. That said, I completely understand that making it taller could cause fitment issues in slimmer cases. Honestly, that’s just me nitpicking. I’d much rather have a slightly taller cooler and better temperatures than sacrifice performance just to save a few millimeters. For the price and performance, the Peerless Assassin is hard to beat.

Good cooler as far as I can tell, will update later on whether or not it keeps it cool under heavy load but I have no doubt that it will do its job amazingly. It looks nice, you could swap out the fans if you really wanted to, i’m just using the ones it came with. Just beware it’s pretty big and does over the ram sticks, so if you care about that then I would sudjest a different cooler. The Material seems okay, and it was pretty easy to install compared to coolers like stock ryzen coolers. The noise level is also not bad, my pc is a little noisy but i think that’s due to all my other fans, the cooler itself not much noise.

5 star.

Produit conforme la description, excellent résultat

Have been using it for a month now. So far has been performing excellently. It runs quiet. Temperatures are 20C lower than with my previous Ryzen stock cooler during Prime95 torture test as well as Cinebench R23 Stability Test. Previously Prime95 used to make the cpu thermal throttle. Installing the cooler itself was pretty simple... I did watch a couple of Youtube videos on how to install the cooler and read the manual that comes with the package. Removing the previously installed Ryzen stock cooler was tougher due to the risk of the cpu staying stuck with the cooler when the cooler is removed, had to do this one very carefully.

Grandioser CPU Fan. Die Preis-Leistung von diesem Ding ist bemerkenswert. Kuehlt alles, hoerst nichts von und kommt guenstig daher. Wer seine Maschine lieber im Kirmes-look haben will hat pech gehabt.

Zeer degelijke cpu koeler. Koelt zeer goed en is van uitstekende bouwkwaliteit. Wel letten op RAM hoogte, maar de koelfan kan wel nog hoger geplaatst worden indien nodig.
