be quiet! Pure Rock Slim 2 130W TDP CPU Cooler | Intel1700 1200 1150 1151 1155 | AMD4 AMD5 | Silver | BK030

Bought two of these. Was surprised that it fit in a micro Coolermaster N200 case. Have a bit of room to close the lid. It is a little tricky to get the hooks on but surprised that it keeps a Ryzen 9600 cpu very cool. I love the copper piping. Isn't very heavy either. Worked great on the two computers I built recently.

I have an ITX-Mini industrial type all-in one ultra-slim open air mesh frame chassis & motherboard with an i7-4790S cpu, that has been a beast to tame workload heat, in this smallest of form-factor chassis, in an open to the elements temperature environment, and much to much dismay, and satisfaction, the Be Quite! Pure Rock LP finally solved my CPU heat throttling problems. The original OEM installed CPU cooler was essentially the basic original Intel aluminum lug & fin, topped with a fan, reference CPU cooler, but cut down to very low 37+mm profile to fit in an ultra-slim desktop chassis. Searching for better replacements I found the Noctua NH-L9i cooler was a few mm's tool tall to fit in the chassis, and that it had height tolerances problems in the CPU clearance zone underneath the CPU cooler. An ARCTIC Alpine 12 LP did fit the clearance issues, and had lower noise, and power use; however still being based on an aluminum lug & fin design, (no heat pipes), still was not able to keep up with sustained temperatures, under even moderate loads. When Be Quite announced their new LP cooler and that it was a copper heat pipe design, fit into the most minimal/maximal dimensions limits allowed for CPU cooler tolerance zones, and could tame even newer generation CPU's, I was skeptical. But as a still last ditch resort to keep a workhorse computer thermally tamed, I decided to purchase one, give a try, with the clearance issues, see if I could even get it installed, and if it could improve on the Alpine LP. Mission successful !!! The install was razor shave close cut; not even micro-micrometers to spare in clearance tolerance all the way around, after mounting; from the top of the fan just barely touching the chassis cover, and with the CPU cold plate fit and around & underneath the cooler; including the cooler and mounting bracket just barely fit over a row of power capacitors sitting just below the bracket. The mounting certainly is "flexible" but this turned out to be a benefit, after getting the mounting brackets and screws tightened into place. The bracket installation wrench provided & needed to tighten the CPU mounting bolts, (not the mounting screws), had some difficulty getting around tight part clearances, that were right up and into the CPU cooler clearance zone, but I was able to work the wrench enough to secure the mounting bolts to the brackets; then tighten the mounting screws. After turning the system back on, immediately I noticed a 10-20 deg F. reduction, as compared to typical temps with the Alpine LP. And even with now spring summer temperatures coming on, and the ability to cool the cpu is being impacted by increase in ambient air temps, the Be Quit! LP has continued to maintain the heat dissipation, through all load testing; most notably that CPU is staying below throttle temperatures where; the OEM installed could never do, and Alpine LP could barely keep up with! Additionally noticed is that the noise level was way down, even at full RPM the Be Quit! Any fan noise had a slight low hum winy noise, but only noticeable at maximum RPM. Overall, this CPU cooler solved a long and ongoing cooling problem in a very minimalist chassis install, and it does it with no no high speed fans, or related added noise.

Easy to install, looks good, runs quiet and keeps the chip cooled

Easy install, quiet fan, and lights

Fan does as advertised, which is really nice. But if you use this with an AM4 chip and ever need to take it out of your case, get ready to do the cemented chip dance with the paste--I wish I had scraped it off and applied my own. If you do use the pre-applied paste, you definitely 100% do not want to remove this heatsink while the chip is cool. Maybe mine was overly dry in the box or something, but yikes.

I put this on an 5900XT (16 cores, 32 threads). It runs cool, it's quiet, well made, and it looks nice. Temps have never gotten close to throttling levels so far. It's far more reasonably priced than water coolers. Mounting wasn't difficult, but you need to change the motherboard fan mounts. Examine the instructions carefully as the mounting brackets are not interchangable, and need to be in a specific orientation. Be aware the heat pipes extend out over the RAM, and there may be clearance issues with some RAM modules. It's also pretty large, and it may not fit in smaller cases.

I gotta say, this is my first time upgrading my PC and it's prebuilt. I noticed a whole difference with this cooler compared to the stock version (coolmaster). I did a stress test on it and I was impressed with the results. Temperatures were normal. Instructions were clear. While you can hear it kinda, which is normal if you're running games, but this CPU cooler is 10x less louder than my coolmaster (which sounded like a jet engine). I will be replacing the rest of the other fans with Be Quiet! products! I may be satisfied with the product, but I will update within 2 months :) AMD Ryzen 5 7600 Be Quiet! Pure Rock 3 LX Multicore Test: 68.4C (MAX) Singlecore Test: 45.6C (MAX)

I just paired this with a Ryzen 9 5900X, I had some doubts that it may not be enough since people in the reviews for the 5900X went on about needing either a monstrosity of an air cooler that takes up a ton of room or a massive water cooler to keep it cooled properly (how far are you guys overclocking this thing??), even after reading into these coolers and their website rating it for Ryzen 9 at 195W TDP. Well, my doubts were put to rest, it idles in the low to mid 40C range and running a stress test and watching it while I was working in ASUS Armory Crate today after installing, the highest I had seen was mid 70C range and I had ran through some more of the demanding stuff to see what it would do, no throttling, no warnings, no blue screens, no problem. I am also not overclocking it and have no intention to do so. It was also pretty easy to install as long as you follow the directions, everything was metal aside from the spacers that fit onto the screws for the AMD mounting bracket. This cooler isn't small either, I have a wider Zalman case and it is just tall enough to where it fits without impeding the glass side cover, but any further I wouldn't be able to get the side cover on, so make sure it will fit your case (my last case on an older machine I had to cut a hole in the cover to fit a larger cooler, bummer). The good thing is that it doesn't block the RAM sockets or anything else on my B550 Plus. I did not want to get a water cooler, and I'm glad this worked out and I'll probably buy more of their products in the future. You may also want to consider buying thermal paste with it, when I got mine it said it was already applied but it was not and thankfully I had some in my desk drawer (I had a tube of Corsair TM30), and I did see some reviews of apparent mishandling of the packaging that caused it to shift and smear paste all over inside the box.
