hey honey how are you like your mush if I see oh I love it I mean it's pretty much perfect I just wish it was a little smaller that was easy so here ask for my spicy mini oh wow you did something useful for once nice spell check it next time too seriously Heather what kind of request was that you're gonna ruin it for everyone the customer is always right ladies ladies there's no need to fight Oh let your voice be heard by visiting the fractal design contact page and making a product suggestion within reason while you're at it you can also check out the new mesh if I see Minnie click on the link below to learn more what's going on guys welcome back to the channel today I'll be taking a look at this brand new CPU cooler from the folks over at be quiet this is the dark rock Pro for the long-awaited successor to the dark rock pro 3 a very highly regarded CPU cooler however this unit brings about some much-needed improvements like a new installation process as well as a brand new heatsink design now this is gonna be a pretty straightforward review but on top of testing the thermals and acoustics of this 250 watt TDP unit I'm also kind of curious at the end of the video if we can actually get away with running this thing 100% passively by removing both the fans I think I think we might be able to do it honestly I mean it's a pretty phat heat stack so that's kind of why I'm curious but more on that later on now before we dive into the installation process I wanted to quickly go over the unit itself for starters we have this dual heatsink design so you actually get two towers and they're pretty pretty fat heat sinks and they have this sort of wave contoured shape to them and these little dimples that are supposed to encourage air so halation the finns are treated with a special black coating that actually promotes heat transfer as opposed to some cheaper paint materials that can often insulate the heat additionally we have some fans here these are silent wings three high performing fans you get a 120 on the outside very standard 25 millimeters thick and then a 135 millimeter fan on the inside that's kind of sandwiched in between both of these heatsink towers both of the fans are four pin PWM and they have nice blacks leaving to match the rest of the cooler the dual heat sinks are joined by a set of seven copper heat pipes which also received the same special black coating that we saw with the fins themselves you get a copper base plate at the bottom and finally a very nice brushed aluminum finish top cover with these various caps that just kind of add to the nice unique aesthetic the cooler supports all of today's most popular AMD and intel sockets with the exception of thread ripper and the installation itself is pretty straightforward there's a backplate that you have to fasten or secure to the back of your motherboard and there will be four screws that kind of pop up you basically have to take four mounting posts screw those two those screws and then mount your CPU cooler onto your CPU with some thermal paste of course next you lay a single crossbar over your copper plate and prepare for screwing there's one screw on either side of that crossbar that needs to be accessed and the only way to reach them is by unscrewing two of the caps on top your aluminum cover and using the included screw driver to bolt them down afterwards you can mount both of the fans using the included wire brackets which are kind of a pain to use and can easily scratch some of the special coating off of the fin stack if you're not careful if the outer fan is interfering with your RAM modules however these wire brackets do allow enough flexibility to lift that fan ever so slightly so that you have a bit more clearance for your memory it's also nice that be quite includes an additional set of brackets if you wanted to mount another 120 millimeter fan to the other side of the heatsink last but not least connect both of the fans to the included fan splitter and then to your motherboard CPU fan header the installation does take a bit longer than most air coolers I'm used to but overall the process has been simplified and is much more seamless than that of its predecessor now that it's installed let's go ahead and fire it up and do some testing alright guys so I currently have our core i7 8700 k-6 core 12 thread part overclocked at the moment to 4.8 gigahertz at one point to five volts and that's on top of a gigabyte horas Z 370 gaming seven motherboard paired with 16 gigs of g.skill tried NZ RGB ddr4 at 3200 speed with the help of the built in XMP profile we also have a gtx 1070 for the wind card from EVGA that's running its stock settings no overclocking on the GPU and that's all being sort of encased inside of this mid tower from fractal design there defined s and I've actually removed all the top much of nth covers just so we have as much air flow going in and out of the case as possible taking a look at the screen here evidently we have GTA 5 running at 2560 by 1080 that's 21 by 9 or an ultra wide resolution and you can see we have an OSD here that has some Diagnostics including our package temp on the CPU which is hovering around 60 degrees Celsius right now which is fantastic for an overclocked 8700 k over here in hardware monitor 71 degrees Celsius is what the is the hottest our package got at any time which is actually isn't bad at all especially when you consider that it was only at that temperature for about a second or two before diving back down to its average range which again is around 60 C so what I want to do now is pop off one of those fans actually it will start with the 120 that's on the outside of the cooler just to see how it affects our thermals I'm guessing that will increase a few degrees but also reduce some of the noise levels and that's what got me so excited the beginning of this video was to see if we could run this cooler 100% passively but now that I have it up and running under full load about an arm's length away from me it's already really really quiet and I don't see the need to remove any fans or tweak it further for acoustic purposes that being said I'm gonna try it anyway because I said I would and because I can so let's go ahead and start off with popping off that's popping off start off by popping off that 120 millimeter fan all right so run around the streets of Los Santos once again here this time with one less fan and it looks like we're still hovering at around sixty degrees Celsius max package temp 70 C same as it was last time and there are no ill signs no thermal throttling of any kind things are looking good I think we're ready to remove the second fan to see once and for all if the dual heatsink towers can hold their own alright guys so we've just booted into windows with zero fans we're now completely passive and we're launching steam right now we're not even in game and we're already hovering at around 80 to 83 degrees Celsius I think we've reached a tipping point here and we cannot go any further in fact the cameras didn't catch this but we've already besotted three times since removing the second fan I'm gonna try seeing what happens if I if I launched GTA 5 I'm guessing another be sod and I think the reason why we were so easily able to ditch that 120 millimeter fan and not the 135 is because the 135 is right in the middle it's actually serving a dual purpose sitting in between both of the heat sink towers it's pulling air through one heat sink and pushing air through the other so it's kind of serving two purposes and it's working twice as hard if you will as that outer 120 milliliter fan which is why it makes such a huge difference please PC gods please please let us not be sod Oh God 89 we just hit 89 and there's the B sod so clearly everything I just said rings pretty true here as demonstrated by this beautiful super ultra wide B sod so immersive so closing things out here I'm very impressed with the cooler overall it's definitely exceeded my expectations in almost every area performances top notch here honestly I'd put it on par with a lot of 240 millimeter liquid AAA OS well I haven't tested against those directly in this video obviously for my experience it is best-in-class in terms of a err CPU cooler additionally the high TDP at 250 Watts also indicates that you might want to pair this cooler with a warmer running CPU it'd be kind of wasted on something like horizon 5 CPU or maybe a core i5 8400 for example but if you're gonna be doing some serious overclocking with a higher TDP chip this is definitely in the running as a potential contender additionally it's quiet AF I mean this thing is almost silent even if you have a case that has a lot of open air ventilation under load you're not gonna really notice it that much and when you do it's not going to be distracting it's sort of a low kind of calming hum overall and it's it's not going to take you out of the game whatsoever the installation has been much improved upon since the last generation it's still a bit long-winded but overall I'm very happy with the changes that be quiet made there and then finally I think it just looks great I think for the money it's one of the best looking air coolers on the market definitely blows any Noctua coolers out of the water noctua coolers perform fantastic in their own right but from an aesthetic department this thing definitely takes the cake between the two so those are my thoughts in a nutshell on the dark rock Pro for guys let me know if you feel the same way in the comments below curious to hear what you have to say about this one also feel free to toss me a look on the video if you enjoyed it and feel free to get subscribed to the channel for more tech stuff coming at you really soon you can also follow me on floatplane if you want to catch my videos a week early without ads for 3 bucks a month I'll put a link in the description for that until next time guys thanks for tuning in have a good one and I'll see you all in the next video
