welcome to a very exciting Linus tech tips video you guys have asked for this this is the performance evaluation of the Kraken X 40 and the Kraken X 60 what's the advantage of a Kraken versus a some other liquid cooler well compared to 120 millimeter radiators it offers 36% more surface area which makes it more effective for cooling with well larger fans that can push more air with lower rpm or well no the same air with lower rpm or more air with the same rpm yes either of those things so we're gonna be checking out not only the kraken x 40 but also the kraken x 60 which has actually whoops not quite made it to the test bench yet not every case can accommodate the kraken X 40 and X 60 you have to have for the X 40 a 140 millimeter fan mount that has enough room around it for you know the tanks at the end of the radiator and well the tanks at the end of the radiator as well as the additional thickness that's required to have the fan and the Kraken mounted there and for the kraken x 60 you have to have a dual 140 mount with enough clearance for a read and a fan and you have to have the correct spacing for the mounting holes or you need to be willing to whip out a drill and make it happen which is what we're gonna be doing with the vengeance c70 here now the vengeance c70 is our standard testing bench so I'm going to go through our standard testing procedure really quickly here so number one is we monitor the ambient temperature with a multi logger thermometer so we monitor that at the intake on the case that tells us what temperature the air being used to cool the computer is then what we do is we correct whatever temperatures we get to 20 degrees Celsius giving you guys a normalized temperature yes it works this way don't doubt us on this it's okay if your room temperature goes up 10 degrees your CPU temperature will go up exactly 10 degrees so we're reporting what you will realistically observe in a sort of a normal climate-controlled house okay fans we do not use the fans that are included with liquid coolers yes there is a value add to the manufacturers including better fans we recognize that but we are looking at it in terms of the cooler with a fixed fan usage scenario and a fixed noise level so we're gonna be using high-quality nacht to offense in the case of the Krakens we are not going to be able to use our standard n FF 12s and we will instead be using our standard nfa 14 FLX fans these are both pressure optimized fans but the difference you'll notice is that one of them is 140 ml and one of them is 120 ml they spin at the same rpm and are approximately the same audible noise level so you know that's holds in line with our methodology of using them sort of in the way that we would use them however we don't run a fan low noise adapter on this one and we do run one on the 120 because that's how we get them running at the same rpm we always run our benchmarks in a closed case with a real system so in this case we're using a GTX 580 from MSI running combustor to generate a heat load because in a real system the inside of the system will have other generating components we're running a 3930k overclocked to 4 gigahertz and you can see here that we also have a procedure for mounting the fans as well this will always have a 120 this will always be dual 120 s up here except in the case where we are replacing it with 140 millimeters in order to mount a 140 ml rad so there's the kraken x 40 you can see over there what we do for our idle test is we just idle it and what we do for our load test is we run combustor and prime95 small FFT then we take the CPU temperatures after a period of about 5 minutes once they've equalized and report them to you so that's pretty much the procedure I can't show you these numbers now because I've gone and removed the side panel and we've changed a few things but we've already recorded numbers we're gonna go ahead and mount the kraken X 60 and show you guys what we had to do to a C 70 to get it to work now with the kraken X 60 what we discovered is that compatibility is maybe not quite as much of an issue as NZXT and/or other case manufacturers would have you believe because here is the X 60 mounted and of course our vengeance C 70 case which supposedly it doesn't work with but we made absolutely no modifications to the configuration whatsoever the one challenge you can see we've only mounted it with four screws here but we could have put in all eight is that the heads of the screws are not that big so we had to kind of sort of you know put them all in at the same time otherwise you could kind of you could pop it through if you didn't have all the screws in because you can see they're not quite centered that was the only issue other than that it mounts fine the clearance is perfect once we're it once we're inside we had the barbs at the back so if you had actually here slick if you want to come around to the other side and give them a look inside there and you'll be able to see I hope unless here bulk blocks it so the barbs come out right above the RAM over there if we had VRM heatsinks over there then that might be might be a bit of an issue he wants me to take off the side panel but we haven't recorded our temperature readings yet so why don't we do that first remember guys we take all our temperature readings with a closed side panel so we recorded our ambience and our load temperatures I just want to remind you that we take the second hottest core so in that case it's this guy at sixty-five and so we're gonna plug that in and find out how this particular cooler performs so this is not really what I was expecting it does perform better than the x40 so it's about 6 degrees better than the x40 also the fan or the pump is very satisfactory on this one we don't hear any grinding or or whining but it doesn't perform as much better than the h100 I as I would have expected so that still puts it at the top of our charts I want to be very clear it is still the top performing CPU cooler that we've had run through our lab so can't take that away from it it's possible that if we had our CPU more over volted or if we had a higher wattage CPU that we'd see it pull away from the H 100 more it's also possible that the the NFF 12s being a higher tech fan than the a 4 teens are better optimized for pressure even though both sets of fans are running at the same rpm and the a14 are inherently larger and should therefore be able to push more air through the heatsink well peeps ain't radiator whatever you want to call it so here I want to show you guys how the clearance was so if you did have tall drm heat sinks here or up here at the top and you can see that this would not have fit but we were able to get it in with our EMA side 65 X 79 board just fine and you can also see that there's no interference over here with any kind of five and a quarter inch bass as well so it's an extremely satisfactory installation experience in spite of the fact that this case is not listed as compatible so thank you for checking out this episode of Linus tech tips where we've had a look at the performance of the Kraken X 40 and X 60 if you guys want to see our performance charts we're actually going to have a link under the video so you can go ahead and check those out at your leisure so you can see all of our results for various colors on our standard test bench and we're gonna keep updating that over time don't forget to subscribe obviously no review of the Krakens would be complete without having a look at the included software now we had CPU temperatures working before I had to reinstall this just now so that might just be sort of a weird thing and fan speed does work we just don't have the fans plugged in right now but I just want to show you guys the feature so you can monitor your pump speed you can know if your pump failed you can see the liquid temperature as well as CPU temperature so you can monitor your deltas here's a graph of fan speed rpm as well as temperature fan settings these are cool so you can set up a few different curves one for silent so you can see that the fan speed here on the y-axis doesn't start ramping up until the temperature here on the x-axis starts to get up to around 45 degrees you can actually move these around so you can make things as extreme or well that's a hundred so you can't really go any higher than that but it's not gonna let me move that okay no interesting may be the custom want to let me move that oh no it just wants you sort of it wants a hundred percent to be around 65 degrees and then you could I mean you could also just go one hundred percent earlier if you wanted so there is a lot that you can do to play around with it and then right so you can just change the dial to extreme silent or custom whatever you prefer and light settings so it's got RGB LEDs inside you can change the colors you can actually have different colors if the temperatures are high you can have it fade and strobe at intervals and general settings are here so you can monitor in Fahrenheit if you're from the US of A and auto start liquid temperatures all that kind of good stuff so once again don't forget to subscribe - tech tips from our boxing and other incomplete videos until we come back and finish them and then they're done and then now we can actually say by in turn the camera off
