Cooling KMPKT Heatsink and Fan Poll

[Kmpkt]

Hey Guys,

I've mentioned this previously, but I am aiming to make a 95mm x 95mm heatsink with 92mm fan to compete with and hopefully exceed the performance of both the Noctua L9i and the Thermolab LP53. I have received preliminary quotes on production for the design I'd like to use, and now I have to determine whether this would be a financially viable venture for me. I'd need to buy 500 units minimum, so I really want to make sure I have pricing dialled in on this. You can see a concept render below:

Intel only or you'll provide and AMD mounting kit too?

 

[Kmpkt]

I am intending to do AM4 and Intel 115x to start. I may add other socket support, but I'm not sure there's a massive need for it as the TDP rating likely won't suit Socket 2011 and with Ryzen out, I can't see any sane person (or a significant subset of my market) using AM3+ or below.

What is the height on it including the fan?

 

[Kmpkt]

I'm aiming for 45mm with a 92 x 15MM fan. May go a little lower as I would really like to fit comfortably inside the S4 Mini.

How does it mount?

Deepcool will be the OEM, so I would think using a set of brackets like this:

I went ahead and voted "Over 54.99" because, realistically, if it was the measurably the best cooler for the job I'd be comfortable paying pretty much any "under $100" price. Granted, I do think ~$50 or less is what most people prefer to spend on coolers and I obviously would prefer spend less than more...

I am interested in seeing how this pans out because I'm already considering ordering dubious all-copper coolers off of alibaba.

I'd pay based on performance - if it can cool noticeably better than the Noctua while making the same or less noise, that to me would make the price worth it.

 

[Kmpkt]

Yeah that's what I'm aiming for. Right now it's got the same dimensions in width and length as the L9i, and I believe the same fin count. The fins are however 28mm tall instead of 21mm tall which means there should be about 33% more surface area to dissipate heat over. Considering the LP53 has more or less the same surface area as the L9i and lowers temps between 6-10 degrees C, I'm really hoping this crushes the L9i by 10 degrees or more. As long as the heat pipes aren't a limiting factor (by my math they shouldn't be), I think the performance on this heatsink should be unmatched. Furthermore I am looking at some higher static pressure fans from Yate Loon and playing with the idea of making a denser fin stack on on of my prototypes to see if I can move more heat.

Man, if I don't have to have that ugly beige fan to be a winner I will throw all the money at you.

 

[Kmpkt]

Yeah right now the demos are black, but I'd actually like to get a grey or grey/black combo not unlike Noctua's Redux line. Also I have put in an inquiry to see if I can have the entire heatsink coated in black nickel which looks pretty amazing if you haven't seen it.

Looks nice, but what's with the cover over the copper fins? Sure it looks nice but does it improve cooling performance?

Hexagon branding

Will go nicely with my Dynamo...

 

[Kmpkt]

That's what I need to test out. I'm looking at this from a design perspective too and copper looks pretty shitty in most builds (everything now is monochrome + LED). The point of the shroud is to provide screw based fan mounting system as well as to obscure the copper somewhat for aesthetic purposes. I will be testing the L9i at some point in the not too distant future with a variety of shrouds to see if the shrouding hinders (blocks air exit) or helps (forces cool air over the entire surface area of the fin instead of allowing early exit). If there is a significant hit to the cooling then I will find another solution. As mentioned above, I am also looking into getting the entire thing done in a black nickel plating to again improve aesthetics.

 

[zovc]

I don't mind the color of copper, personally. I think it's a lot more acceptable as an accent color than beige or brown are.

But, like you said, black/grey/silver fit into 'monochrome + LED' builds a lot better than copper does, in general.

 

[Kmpkt]

Yeah, but I have to consider broad market demand. We're a pretty small subset of the overall market and a lot of people place equal weight on aesthetics and function. Like I said earlier, I need to move a lot of these.

Just a note that Dan (of Dan-A4) is making a 48mm (3mm more) heatsink.
It will be similar to the noctua NH-L12 in design (c style cooler) but accomodate slightly larger fan (92/100/120mm fans)
I would imagine since it is larger and exceeds 95x95 footprint that it would perform better
Thoughts?

Copper and aluminium have slightly different properties. Copper is better at drawing heat, and ally is better at radiating it away.
In other words, a copper contact block for the CPU and ally fins is the best combination.

Yeah I did reach out to him at one point via PM letting him know I had a much more reasonably priced OEM with good quality in case he wanted to work together, but received no response from him (which I take to mean no interest). As far as his design goes, I can't get over how much of the heatsink on his renders is NOT in the airflow of the fan. I don't know if he's rendering with a small fan or if the fan has to be small to fit in the keep out zone, but I just don't get the point of having a 130+mm fin array with a 92mm fan. Maybe someone can clue me in?
