be quiet! Pure Rock Low Profile 100W TDP CPU Cooler | Intel 1700 1200 1150 1151 1155 | AMD -AM5 AM4 | BK034

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.

I don't know how they make it so quiet. Stock fan/heatsink was revving up quite a lot during normal use. This thing i can't hear at all, and things stay much cooler inside. I was worried i'd loud, being only 92mm, but no, it's whisper quiet. Love it!

Needed a new fan on an old rig. (the mount broke on the old fan and it was grinding like Tony Hawks proskater). It was so loud, like jet engine loud. And the cpu was hitting 100 degrees C!! After a quick repaste and fan swap it went down to 55-65 C. I even dialed up the fan to max speed and it was pretty quiet. We'll done. Great product. The LP version took a little phenagling to mount, but nothing too hard.

Great product works flipping amazing! Will keep your CPU cool. Also while looking cool. Even though you won't see it because you're jamming it inside a computer case it's still the coolest looking thing in your computer case!

My CPU was running a bit too hot for my taste on an inwin Chopin case. I was skeptical about swapping the cooler+fan, but you can easily see that with the stock fan air recirculation is almost guaranteed. I notice between 5 and 10 degrees of improvement while running stress test with s-tui on Linux. The fan doesn't touch the metal screen, I will try do make a "duct" when I have a chance to make it even better by forcing only air from the outside. WARNING: Most if not all cases will require you to remove the motherboard, as the cooler has to be screwed from under the motherboard.

its cut, tiny abd it works, bit pricy however the quality is good, hope my i5 stays cooool

My stock fan was very angry to run at full speed. So angry it would scream over the explosion in my headphones to get attention. I am very happy to confirm this new fan is much less vocal about my gaming habits... i7 - 10700 maxed at 63° C running a super unoptimized 3D space survival game 4hrs straight

Perfect, looks so goood and quiet

Ottima, bassissimo profilo e ultra silenziosa. Performance ottime

Ich habe zwar kein Micro ATX Board oder super kleines Gehäuse, dennoch habe ich mich für den be quiet! Pure Rock LP entschieden, da mein Gehäuse eine Glasfront zum durchgucken hat. Und das Design ist puristisch gut. Kein alberner "Lüfter-Turm", der ins Gehäuse rein ragt, sondern einfach nur ein schöner quadratischer Lüfter. Weiterer sehr wichtiger Punkt war für mich aber der Geräuschpegel, aber auch hier wurde ich nicht enttäuscht. Der Lüfter läuft wirklich SEHR leise. Die Installation ist ein bisschen "fummelig", dennoch Kinderleicht. Man muss zunächst den richtigen Schraubensatz auswählen: Intel oder AMD. Beide sind in separaten Tüten dem Lüfter beigelegt. Anschließend muss man die Teile zusammenbauen. Ich kann nur für Intel sprechen: hier muss man nun die richtigen Abstände bzw. Positionen beim Zusammenschrauben der Einzelteile finden, so dass es dem Lochabstand auf dem Motherboard entspricht. Die Abstände für unterschiedliche Sockel sind nicht in der Anleitung genannt. Tipp: Nicht gleich die Teile auf dem Lüfter festschrauben, sondern erstmal die zwei zusammengebauten Einzelteile zur Befestigung auf dem Board bzgl. des korrekten Abstands prüfen. Ansonsten klebt nämlich die bereits aufgetragene Wärmeleitpaste auf dem Lüfter und ihr müsst den Lüfter wieder entfernen, wenn nicht zufällig der gewählte Abstand passt! Wenn der Abstand passt, können die Teile auf dem Lüfter und letztendlich dann der Lüfter mit 4 Schrauben von der Rückseite des Boards festgeschraubt werden. Und Achtung: nicht einfach den Lüfter mit der Unterseite auf einen Tisch etc. legen. Die Wärmeleitpaste ist bereits aufgetragen und würde sofort auf dem Tisch kleben.

Super easy installation. Very minimalistic look too.

とても静かでよく冷えます。 付属ネジが一部欠品でしたが、サポートセンターの方のご対応がとても素早く、助かりました。

Lo tengo instalado sobre un Ryzen 7 3700X, con pruebas de Cinebench 2024 y con la pasta térmica pre aplicada de fabrica, me da una temperatura máxima de 85 grados, durante un uso normal y con videojuegos, no eh visto que pase de los 65 grados, así que siento que trabaja bastante bien este disipador, espero que con un cambio de pasta a una mejor, las temperaturas bajen sobre los límites actuales. Solo comentaría que si piensan usar algún procesador con un TDP mayor a 100W, mejor busquen otra opción de disipación, porque si siento que les quedará corto, al menos que piensen hacer undervolting o usar metal líquido o cubiertas de carbono para mejorar la disipación.
