air coolers are very upfront regarding cooling capacity the TDP of for example a dark rock Pro for which our view tomorrow is literally written on top of the box more about TDP by the way in this video right here liquid coolers on the other hand with very few exceptions of void this metric TDP but why the reason has to do with much of what was discussed in this video right here regarding a iOS and why they're inadvertently lying to your why you might be misled by what they're showing you on-screen since liquid coolers use just that right liquid as their transferable mediums in place of heat pipes in the vapor inside the TDP of an a io is largely dependent on the temperature of the liquid as well as fin density surface area pump speed and fan displacement with most air coolers heat pipes filled with pressurized vapor handle the transfer of energy not water so in the case of the dark rock pro four seven six millimeter copper lined pipe stretched from the block below to the aluminum fins above copper conducts heater to rate much higher than water so things equalize fairly quick the tiny amounts of a parade in facilitating the rise of heat from the block so much like a mini water cycle the compound vaporizes near the heat source and it condenses near the fins the vapor isn't absolutely necessary by the way many cheaper heat sinks don't even have copper pipes or anything like that but it certainly does help now with a iOS and the TDP actually changes as the temperature of the liquid does so the true TDP of a liquid cooler is derived from the system at thermal equilibrium when the water is warm to a point where the fan rad combo dissipates heat from the water at the same rate that it conducts it from the block this is usually between 40 and 50 degrees Celsius to be on the safe side with respect to the pump now I know that was a mouthful but rest assured most a iOS this is what you need to take away from this don't have particularly phenomenal tvp's for example the deep pool captain 240 X I doubt it all the time actually settles in at around 150 watts they're one of the few companies to actually list a IOT DP so good guy deep cool but something to note is that this TDP is significantly lower than the dark rock pro force for example despite having roughly the same bin density and weight this is because an AO s performance is strongly linked to its speed now the same goes for air coolers but this is where things get really dicey so the DRP for again utilizes seven heat pipes but the 240 X boasts only a single tube of moving water thus the speed of the water up to a point does matter in a closed loop with a low heat tolerance but the fan speed can drastically alter TDP because of the fact that water from only one tube is being pushed to the radiator where its post to be dissipated right from those fans so there are several steps that need to align perfectly for the system to function the way that it should on a side note most AIO is recycled the same a Sutekh pump design while their low-profile and quiet they typically don't cycle water quickly enough from the block and thermally demanding systems which results in an imbalance temperature distribution across the system by the way for those who sport you know consumer grade hardware up to maybe the i7 8700 k you're not gonna venture into this kind of territory with a 240 ml a io in most cases you'll be fine pump speed won't matter but this is exactly what happens with a deep cool captain 240 X when paired with an overclocked a 970 900 X which is an egg fryer there's no other way to look at this thing I have to run these fans at max rpm to even give it a chance but if we assume that the heat building up in the loop is carried quickly enough from the block which is the case in most cases that's where pumps reside by the way in the blocks of these a iOS then the fans become the major factor I imagine deep coal engineers ran these TDP tests with an out-of-the-box fan curve which is what most would run their a iOS at hence the lower TDP rating and they also allow the liquid in the loop to equalize at around 40 or 45 degrees Celsius but in this case with enter Max and their link max to system which I'll admit I haven't tested yet they claim is 350 watts plus so how can two AOS with comparable rat real-estate have such a vastly different TDP s because the testing is subjective enter max likely ran their test under max fan stresses and before fluid temperatures in the loop equalized even if we assume they did one of these two things it's not a good practice so when temperature deltas are higher the rate of heat transfer is also higher it's thermo 101 and it's why the inter max cooler probably appears to be a much better cooler than the deep cool counterpart but this is vastly misleading if something seems too good to be true it probably is I mean come on 350 watts and then the Plus on top of that that's just that's just a little comical but in my hunt for other a IOT DPS I always disappointed course there EVGA NZXT NE the big box brands out there did not post a iot dps and their websites and i have a feeling it's because they're conflicted tell the truth and reveal that you're a iOS are actually not god sends with crazy cooling capacities or go the inner max route and overhype your product on the back of discretionary science in closing i'd like to hear into max's explanation i don't believe for one second the cio is capable of handling 350 plus Watts TDP that's just that's just insane that's like saying that you could slap this thing onto any I nine CPU or thread Ripper CPU assuming have proper contacts and it would run like a charm that's just not the case your fans are gonna speed up to max rpm and once your fluid equalizes you're gonna have a really really bad time so there you have it that at least is why I think the TD piece of AI o is often to go unlisted this isn't a science this is just my assumption based on what I've seen but I want to know what you think and I want to hear from you in the comments below be sure to leave a comment I'll check them out within the first hour - of this video going live I also want you guys to give this video a thumbs up if you thought it was cool dislike it if you feel the complete opposite or if you hate everything about I think and feel free to do that as well I will sympathize with you if you wanna click that red subscribe button that would be totally cool with me you can click that Bell notification icon by the way if you're especially awesome so that you're notified with videos like these go live it helps me out every view does count and I take them all to heart I appreciate you guys watching these videos up to this point this is science studio thanks for learning with us you
