Your explanation of percentage points is. confusing. to say the least. Yes, percentage points are extremely relative as there needs to be an original comparison number. That original comparison number can be ANYTHING, that's why marketing loves it so much, because it's not required to disclose what that anything is. Let's take actual examples. Well first, let me say this. Kelvin and Celsius are on the same scale. One Kelvin is equal to 1 degree Celsius. The Kelvin scale is just shifted up 273 degrees Celsius. That's all. Anyway, back to percentages. I'm not going to use units here as they don't matter. Say I have the number 50. If I then have the number 100, yes, that would be a 100% increase. However, if I have the number 100, then I have the number 50, that's only a 50% decrease. See how percentage points can be manipulated? You can change the same data to look better or worse just by changing the way you compare the numbers. Also, percentage points are USELESS at very large or very small numbers. This time units are useful. Say we have an imaginary cooler that can bring a CPU to 1C above ambient. Then we have another ambient cooler than can bring the same CPU to 0. 9C above ambient. That second cooler could then go to say Our cooler cools 10% better than so and so's cooler. And this is. correct so long as by better they meant degrees away from ambient. Is it misleading? You bet your ass it is. Does it happen? Absolutely. In practice, those coolers are likely very close to identical in cooling capacity. The BEST way to compare heat exchange devices would be units of power. So that would be Watts, exactly how lots of them are advertised. however the advertising is often straight up lies. Coolers are often advertised by the largest wattage CPU they can adequately cool. And that adequately is completely arbitrary. A watt would be how much heat (in joules) can be removed from the system per second. This removes much of the ambiguity with temperature and everything that has to go with that. If coolers were forced to be tested under identical lab conditions (temperature, humidity, airflow, thermal paste, etc) and were forced to put that wattage number on their box, we wouldn't need you as we could accurately pick the best cooler based on that number alone. Hell, the best WAY to test coolers would be to stick them in a temperature/humidity controlled vessel, stick a literal heater to them, then test how much power has to be sent to the heater in order to keep it at a certain temperature. This would be the LITERAL amount of power that the cooler can dissipate. Of course, this would change depending on what the environmental parameters were set to (initial air temp, humidity, etc, but as long as you kept it constant you'd get REALLY good and REALLY accurate results. Hell, you could even do it at 2 or 3 different temperature/humidity combinations and post all 3. You could make a nice 3d graph out of it actually. Ok I got off topic. Basically. POWER is the best unit when talking about heat dissipation. Just not the shitty, inaccurate, purposely misrepresented power that the companies currently use. I mean actual MEASURED power, like with a Kill-A-Watt meter.

It sounds to me like they had people doing CFD simulations, but once they actually produced the thing they found that once it was built, the product didn't perform like how the simulations said it would. But by that time, the marketing team was probably off and running and authoring everything based on the ideas found in the simulations. At that point, the dudes doing the actual technical work decided to ditch the grooved idea, but no one communicated that to the marketing group, so when they say we misunderstood the internal structure, they mean the marketing and PR team, not necessarily the whole of the company. Companies very often have communication difficulties like this, and mistakes like this can happen. The marketing people don't understand the technical details of the products on a low level, that's just not their skillset. The technical people deciding what to order the fabrication people to produce don't necessarily have a very direct line of communication or even knowledge that they would NEED to communicate to the marketing folks. Someone in marketing might've taken the information and ran with it without the technical people even being aware hey, those sim results are going to be used as a primary point in the marketing. What are the chances the marketing people spoke up and said 'hey, we are going to market the product this way'? That's the sort of thing technical people are either unlikely to be able to give good feedback on, or actually likely to give BAD feedback on. They might tend to say 'no no, you should talk about this other thing' that the marketing folks know just isn't something likely to resonate with consumers, so they don't even bother talking about promotional plans, while the technical people wouldn't know the importance of the grooving when they find the simulations didn't match the reality so they dropped it.

BTW: I loved this guys integrity an straight forward fairness for the people since before he even BLEW big, I am so happy he did as there is not a better man for the job! He was going to BLOW without the others boosting him they just tried to capitalize. First to really explain to us about nano sizes within intel cpu's, etc. which is very important as leads to, umm, everything which is what the entire race is REALLY about. Stephen will prob never get another component or sponsor from #deepcool however it will not matter as WE will not buy it an they will fail whilst Stephen will grow even larger. making way for a new company with more integrity in its place. HAHA, Not only did he tell us and all with this video but he showed us the email they sent him how they said no need to mention it so honest, so deserving, a Real Man. A Great Ambassador for us Techies. It is a great Time for Tech On YT. -Stephen from PHILLY. PS: Each one, Reach one, Steve, give Bryan from Tech Yes City a Boost - he so deserves it. and I am Not being bias as do not know him nor have nothing to gain by saying this, just a great MAN as well. BTW: Maybe give DeepCool a Chance to take a financial blow for their mistake ViA. re - engineering one of these the way it was PromiseD and send it to every person who ordered one. without having to return the OLD junk nor any weird stipulations as in a TOTAL LOSS! Otherwise, screw DC. A shame as their name is like Dream-Cast or closest thing we got, however, we will LIVE! ;) #derrrp

Good review but there are some issues with testing sandwich coolers (literally each one of the brands have these issues): 1. Those type of coolers need a cover over the fins so the flow is forwarded optimally to the exhaust part (second fin stack) 2. Second fan (the one slotted in the middle) is usually not very well securely mounted (missing rubber dampers between the fan and the input or first fin stack. A small oversight when hooking the brackets of the fan or defected hook can lead to future slip which can potentially break the fan blades. You can guess what could happen in the PC case at speeds of 800 or more RPMs Good point on the downforce part. The computer coolers are nothing more than an aerodynamic machines - better design of the flow moving through them means better (energy used for fans + energy and materials used for the making of the cooler): (heat dissipated) ratio

Absolutely a Bait & Switch/Fraud. You thought you were buying one thing and instead were sold another. If you want to get really technical, it's FRAUD. If I bought a car listed as having a V-12 engine and got a V-8 it would be the same thing. Yeah you can't see the difference unless you open the hood and look and that's EXACTLY what happened when you cut the pipes open and looked. BUT don't get things twisted, I would never buy a car that I didn't first inspect to verify the Specs, then test drive. I would just be FAR less likely to cut open a heat pipe on my CPU cooler to see and that's EXACTLY what DeepCool was counting on. They knew, they knew all along and then changed their tune in October. I won't be buying anything from those greasy jackholes at DeepCool. I wouldn't anyway, they might as well be listed on the same level as that company DiabloTek and their combustible PSUs.

With a static cooler, no moving parts, there is nothing to wear out, except the fan. So there is no real reason to upgrade to another static cooler unless you're also upgrading motherboard that doesn't support your cooler. So manufactures have to find a way to sell you a product you don't need so they can continue to sell products. They achieve this by having you believe that the new product is better in some way when actually, it's not and you're just wasting money. The same reason every single component in a brand new vehicle has engineered defects built into them so the vehicle will only last the length of the warranty periods under normal driving conditions. Otherwise, if cars lasted 20-30yrs without needing major work done to them, the car manufactures would go out of business even faster than what they currently are.

Have you ever considered building a synthetic thermal load? A device that closely matches a real CPU but contains a heating element and temperature sensing system with a microcontroller that controls the heating element to closely maintain the wattage specs you're looking for without needing to rely on software tangentially producing that utilization. It wouldn't give numbers that directly compare to actual CPUs, but it would be extremely consistent to itself and should give a solid relative reference for real CPUs. Say, this cooler gave this synthetic data, and this actual CPU performed this way; this other actual CPU differs like this so we would expect X. A big advantage of synthetic load would be that you can easily and autonomously test for a number of different wattages to capture a curve of performance

more like an engineer brought up that he could make it better. and they prolley was like. we could make it better. or? we could lie our ass off! who gonna know? more profit less expense. than they got contacted by you. and acted all innocent. like we didn't understand the words that we're coming outta our mouths. than claimed its a feature. that they tested it. and the and decided not to go with it. cause they say they tested it and it performed as good as stock. i doubt they ever tested shit! the first response is usually correct one. an oh shit moment! when they realized there lies where gonna come to light. lie there ass off! with enough vagueness. to not get pinned to any thing. where any thing they say can be taken in so many ways as to not be a definitive statement i think you call it nebulous

Ehh. I built my wifes current PC up around a Deepcool case. Originally bought it for myself, but after getting it home and having a good sit down with it decided I didn't like it. She doesn't care, so I used it for her build. After building it and getting a good look at the case, it just seems super cheap for the price. Plastic window, poor fit and finish. Which is sad because it had some pretty not bad reviews, price was good, though I got it on sale. Ended up going with a Corsair case after, which was only around 30 bucks more, but has tempered glass, better fit and finish, and all and all just a nicer case. I wouldn't trust deepcool on anything they say.

Marketing = Corporate Propaganda and is at heart no different from Government Propaganda. The basic definition of propaganda Propaganda - information, especially of a biased or misleading nature, used to promote or publicize a particular political cause or point of view. Can be easily and truthfully be rewritten as: Propaganda - information, especially of a biased or misleading nature, used to promote or publicize a particular Corporate cause or point of view. Once you know what you are actually dealing with makes it infinitely less effective so treat all Marketing just like you would treat any other type of Propaganda. as BULLSH T,
