So I outrageously peaceful!

brilliant cooler cancool up to 250w cpu power however no room left after fitting so build after installing ram and before installing main board.... hope that helps.

Could even use it in hot summer days to refresh myself

Good fan as it works

Solid build. Not the easiest install, but now it's in, it's doing a great job.

So far she good and very quiet

Good value for money, genuinely doesn't make a sound!

Great product, recommended

This is certainly a big cooler and seems more than capable of keeping an i9 processor cool. Easy to fit before you put the motherboard in situ since it requires a backing plate which is provided.

Top notch cooler. I installed on a Ryzen 9 5900X and it works a treat.

One of the best air coolers at a very good price from CCL. Lives up to its name being very quiet and efficient - highly recommend.

Good price, quick dilivery and easy install

Really easy to setup and keeps my r7 5800x under 50 when overclocked. It looks clean. Only downside is it covers ram because it's quite big but it's still really good would recommend.

Super quiet.

Sometimes CCL has good price

Solid cooler but the fan in the centre actually runs a little loud (louder than my NZXT aer rgb 2 case fans anyway) - and the heatsink is MASSIVE (blocks one RAM slot on my motherboard though I do have very tall ram - Corsair vengeance rgb pro)

Superb CPU fan. I wanted one of the quietest coolers, but with best cooling and this fits the bill extremely well. I was told that water coolers are best at cooling but can be noisy. This is one of the best air coolers on the market in my opinion.

An absolute great purchase!

Very quiet and fit nicely into my Phanteks 600s case

Its been a while since I have used Air cooling for my CPU, but due to my AIO coming to the end of its life and the pump failing I decided to go back to Air cooling. I watched alot of reviews on youtube and there are alot to choose from. I had made up my mind when I saw the quality and style of the Dark Rock Pro 4. The Be Quiet Dark Rock Pro 4 Air Tower Cooler has got to be the very best cooler out there, Yes it does have a large footprint in your system but it looks awesome and its is literally so quiet I was shocked at how quiet it is. Also with the 120mm & 140mm Fans blowing across the fins keep your CPU to a nice cool temperature. I am more than 100% happy and would very highly recommend this cooler to anyone, in fact I have already converted a friend from his existing cooler to go with this one too.

Great cooler with lots of heat dissipation

A bit pricey for a CPU Cooler, but it works great and it is quiet.

Highly recommended, very silent fans, fairly easy to fit as i had to remove my motherboard from the case in order to mount it as it is on the large side of things. looks great in all black and no RGB which for me is a bonus. Slightly on the expensive side for an air cooler, but id still recommend it too. Also delivery was very fast and it arrived 2 days after ordering it !!

Works with i9-9900k and stay silent. Keep temperature under 55C. But for a wide cases only. Nice alternative for a water cooling.

very quiet

Keeps everything cool

Easy fit and keeping things cool

I was looking for a good quality CPU Air Tower Cooler for my new PC build, I liked the look of the Be Quiet! Dark Rock Pro 4 so I bought one. I'm an engineer and I was very impressed with the German build quality of this product it is superb, it came beautifully packed with a free good quality screw driver. I found the Be Quiet! YouTube video on how to fit this product very helpful and useful, just follow the video and you can't go wrong. It has been working really well, the fans are so quiet you can't hear them running, and it looks great when fitted. I can highly recommend this product.

The hottest temperature I've seen on my CPU (Ryzen 7 3700X) is 71'C when running Cinebench. At 70'C the cooler became audible. 5 seconds later, the hot air was exhausted from the Chassis and the temperatures dropped back to 56'C, and the fans became inaudible again. I haven't heard from them since. It says its rated to 250W, but I'm using it with a 65W processor running at Stock/Boost speeds only. Not a single problem so far.

A great cpu tower cooler, way overkill for my CPU which is only a AMD Ryzen 3600 at the moment, but I figure this cooler will last me through several upgrades. The benefit of this cooler over the supplied AMD Wraith Stealth cooler is my CPU now highs higher boost levels which can be maintained for way longer. With the stock cooler my CPU was hitting 95c and barely topping 4Ghz, now it can sustain over 4.2Ghx all core and max out at between 63-67c depending on ambient temps, usually around 25c. Fitting is easy as long as you do it before mounting the motherboard in the case, sadly I was replacing the stock cooler so this made the install a bit more difficult, but not that much harder. Sound wise, its quiet, and the dual fans push sufficient air to keep the CPU nice and cool.

Easy to install with supplied screwdriver and is very quiet, highly recommended

Excellent cooler. Looks awesome and performance is great. Fan clips are a pain to use but the rest of the assembly is pretty simple when doing it outside of of the case.

nice and quite and keeping everything cool. Quite a tight squeeze though. Make sure you seat your ram properly before you install.

Bought this off my husband's Xmas list, and he is very happy with it - he was not even sure his PC actually worked, it was that quiet - he says 'highly recommended'! :)

Hello, I had water cooling corsair water cooling h100i and I changed it and I have to say that I'm 100% satisfied and I'm not going back to water cooling. I recommend very quiet and efficient !!!

A very quiet cooler, works great on my ryzen 7 2700x. Would recommend to anyone after premium quality aircooling.

awesome aircooler you need a big case for it

As it says on the tin .......very quiet .....my Ryzon 7 rarely goes over 50c ....and averages about 35c doing hard-core gaming .

This cooler is absolutely AMAZING! I've put it on an i5 processor and the fans are basically useless because even with zero rotation the processor is at room temperature + few degrees (e.g., aftware 8 hours of work the temperature is 29C with the fans at 300rpm). So it's quiet for sure. The fans are gorgeous as well because are serious metal fans that will last forever. The RRP price is lower than other competitors and the quility is FAR superior to any other I know. Look: you cannot find something better than this. It looks like a piece made by NASA for the space shuttle. It look really serious stuff taken out of a 5 billion mainframe. The only cons: when installing the cooler, the first time it's not so easy to add the external fan with its clips and you could easily scratch a bit some part of the heatsink. Looking at the video on their website doesn't help much on this matter. But this is the only negative side I know that is avoidable with a bit of care. Another obvious point: be sure you can fit it inside your computer because it is REALLY, REALLY, REALLY, HUGE. HIGHLY recommended for life and I'll buy it again and again. It's a piece of art.
