The modern PC is potentially a mass of heat output and heat production hot spots. With CPUs rated at more than 100W of heat output, single graphics boards carrying similar ratings (and people want to run two!), multiple hard drives the norm, lots of memory and mainboards covered in heatpipes to combat toasty core logic and PWM circuits, a PC appreciably warming up a room when it’s working hard is no joke.

be quiet! Dark Rock PRO 4 Dual Tower CPU Cooler, 7 Heatpipes, 120mm+135mm Silent Wings PWM Fans, Al/Cu, 250W TDP is rated 4.7 out of 5 by 6.
Rated 5 out of 5 by from Big boy This big bad boy will cool any CPU you have to a nice cool temperature, When it's idle its really quiet but expect the noise levels to go up when you start gaming or pushing the CPU to its limits, but even then it's quiet for a cooler so large. Another positive is the cooler comes with AMD and Intel sockets separately so it will fit on most motherboards and CPUs Only problem is its fiddly and can be difficult to install, especially for children. The silver lining is that the instructions are clear and don't leave you scratching your head. Also the name of the product reminds me of my teacher "Be Quiet", so thanks, be quiet.

Rated 5 out of 5 by from A Silent Beast A Silent Beast. Be Quiet with its reputation as being silent with quality and performance, lives up. The Dark Rock Pro 4 is some engineering achievement. With a NZXT H210, being mITX format I went for this case so I am not restricted in tower cooler choices compared to most mITX cases, The DRP4 fit snuggly into the case, and highly recommend assembling outside of the case but this may vary depending on your case. I went for RGB RAM instead of low profile memory and yes this may be counterproductive, though I went for a single fan configuration (middle fan only) on the DRP4 and with an exhaust fan on the case it is acting as a rear fan for the cooler as well since it is so close to the DRP4. Also, this configuration looks even sleeker. With some research online, it also showed very little performance difference in this configuration, again this could be depending on the airflow of the case. RAM clearance is good on the DRP4 and didn’t interfere with my G.Skill Trident Z RGB kit but anything taller and you’ll be having problems. However, the DRP4 must be noted is massive and it often covers two memory slots with the standard configuration but with my single fan config it only just about hangs over the first memory slot, though at an angle both memory modules are visible which worked for me. Before I was using the stock Ryzen Prism cooler which provided decent cooling but it had an annoying whining noise so this DRP4 completely removed that issue. The stock cooler performance gave me around 70-80 degrees in gaming and around 80-95 degrees (95 is thermal limit for the 3900X) on synthetic benchmarks e.g. Prime95. After replacing the stock cooler with the DRP4, there was cooling performance gains. Now achieving around 55-60 degrees in gaming, and 60-80 degrees in synthetic benchmarks. Both results are with stock settings on the CPU but with a conservative fan curve to try and keep noise levels down, however, I never had an issue with the DRP4 cooler fans nor with the Be Quiet case fans I also picked up. Better temperatures could be had with some more tweaking especially with voltage settings as Ryzen seem to have weird voltage behaviour. TL;DR – Highly recommend the product for any enthusiast or just wants near complete silent performance. Also highly recommend assembling outside of your case, and I would really advise in checking if your RAM modules are compatible with the clearance before purchasing and finding out the hard way. It isn’t the easiest cooler to install but it was definitely less stressful outside of the case. Excellent price to performance as well compared to the competition.

Rated 5 out of 5 by from Absolute Monster This is excellent keeps a 3700x @ 64c on full load after 30 mins of stress testing. If anything this is overkill for any cpu new or old but it’s performance is astonishing. It also looks like a monster like you know when you look inside of the pc case it just looks like it means business. Would highly recommend to anyone just make sure to check your ram clearance you can adjust the fan to fit to an extent but if it’s too high you’ll run into issues.

Rated 4 out of 5 by from Almost perfect. Does a fantastic job taming my 9900K which can be quite a toasty chip! It's easily the quietest cooler I've used! My Cryorig R1 Ultimate is much louder! Even under full load in a stress test this thing is whisper quiet. Temperatures in Linpack Extreme [30GB RAM stress level with RAM running at 3200 16-18-18-36 1.35V] maxed out at 94C but averaged about 87-88C. It's called Extreme for a reason as it puts insane and unrealistic loads on your CPU. Very few, if any, stress programs will put this much load on your CPU. This is the absolute worst case scenario! With IntelBurnTest [Maximum stress level] it maxed out at 74C! This just goes to show how insane Linpack really is. IntelBurnTest is a bit more forgiving but still an unrealistic load. During games I am anywhere between 40-60C. Usually 40-50C but it can hit 60-ish sometimes. The reason I have only gave it 4 out of 5 stars is because it's so awkward to install. I have read that this is actually an improvement over the previous version lol. Here is what makes it awkward and how they could improve it (there is TL;DR at the bottom): 1) Mounting arm is not attached to the base plate so you need to sit the cooler on the CPU and line up the mounting arm with the screw holes on the bracket. To improve it they could just attach the arm to the base plate so you're not messing around with it. At the least they could change the little notches on the arm so it easily aligns. Oh and you need to try do this without moving the cooler which will slide about because of the thermal paste! 2) It took a few tries getting the screws into the mounting arm/bracket because the screw kept falling off. Maybe my hands are just too big but I couldn't really use them to get the screw to sit in the hole. If the screws were held in place on the arm with a spring it would it so much easier. 3) Attaching the fan is awkward!!! This was actually the hardest part believe it or not. One fan is already attached but you need to attach the second one because it sits over the mountain arm and screws. Sliding the fan in between the two metal fin stacks was easy but getting the hooks on them was difficult. I could get the bottom side done but getting the top one was a nightmare. I ended up having to remove my entire motherboard from the case just to get the fan on! If the hooks were easier to get in and had a bit more flexibility it would seriously improve installation. TL;DR - don't try install this cooler with your motherboard in the case. It was a nightmare. The easiest way to install it is removing the motherboard so you have a lot of space because it is just way too awkward to do inside a case. The fact that I have to do this is just a huge hassle. Thankfully once it's on you really shouldn't need to take it off for a long time. All I can say is that I dread when the time comes to clean out my PC and I have to remove this thing. In fact I probably won't even bother. If anyone from Be Quiet is reading this please make a revision. It's just some small simple changes that would make the cooler perfect. If you want to know how to make a cooler with good installation then take a look at the Cryorig R1 Ultimate. It's a breeze to install that. The Dark Rock Pro 4 performs much better and is quieter but is a nightmare to install.

Rated 4 out of 5 by from Recommended with one HUGE reservation The Dark Rock Pro Dual Tower CPU Cooler is good looking and efficient, my BIOS reports CPU temperature as <40 degrees Celcius. It is acceptably straight forward to fit and it does the job. THE RESERVATION It is ENORMOUS; and I wanted to fit RGB Memory. In its standard configuration the cooler may cover Memory slots on the Motherboard, in my case two. To fit the RGB {deeper} memory modules I had to reverse the rear case fan and the cooler's fans and add extra exhaust Fans to the top of the case -- the cooler still covers one slot, even so. However: my solution works, everything stays cool and the computer works.

RAM Compatibility

I apologise in advance, I can&rsquo;t find dimensions. Aorus gaming 7 motherboard Corsair Vengeance RGB LED 16GB DDR4 2666 Memory Kit 2x8GB I want to ensure the RAM will fit under this fan with no major issues. Many thanks
Asked by: Zorodek
Hi there, I am using the Corsair 32GB Vengeance LPX DDR4 2400MHz RAM 4 x 8GB and the fan fitted over the top, just please make sure you install the RAM first and then the fan afterwards. However, your RAM sticks might be a little taller so it could be a tight fit. I'm sorry I can't be more specific and about the exact dimensions. Good luck
