    Still doesnt guarantee that it ll be sub-48mm, so we ll see...

    also "hopefully" is pretty vague.

    They already have the L9x65 - if they weren't going lower than that, I don't see why they wouldn't have just suggested that. "Hopefully" is only vague in terms of timeline, not eventuality.

    "Working on it" is as solid as possible for an answer. It might not be out soon but it exists.

    Looking pretty with direct touch heatpipes too :) . Are the fin spacing bends necessary for the middle of the heatsink? And can the outer ones be placed on the outer edge in the unlikely event that we end up using a 120mm larger fan?

    Just wondering as there might be a good manufacturing reason or design behind those.

    Is that the thermalright ty-100 fan?

    Hi Dan,

    I've detected some posibble flaws in the design and I have some suggestions to make the HSLP-48 perfectly adapted to A4-SFX and more efficient:

    In this type of heatsinks the fan is used to be placed on top of the heatsink, covering the whole top of it, ensuring the air pressure to pass throught the fins.

    In this design there is a smaller than the sink fan below of it, so a big part of the air will go up, crash on the cover and return to the case through the open sides.

    If it isn't possible to use a bigger fan that covers all the fins and also covering the sides with an end plate (like the falcon but inversed),
    it is needed to force all the air out of the case. So I propose to cover and seal all the gaps to make a high pressure chamber or wind tunnel, to force the air out of the case (something like the gpu or notebook heatsinks)


    Here you have the changes in the bottom side:


    https://preview.************/kJVHiv/key_nexus_1200ailp0.jpg

    On top of it, its needed a perimetral rubber to seal the high-pressure chamber and force the air out, and it can reduce noise vibration also, if it gets in contact with the case.
    (a perimetral copper plate may be required to sit it, maybe the end of the fins can be bent):

    https://preview.************/ny2V3v/key2_104qvkpl.jpg

    All of the parts can be made out of plastic, aluminum, or the same copper which may be cool (if you want to maintain the fancy look)


    The principle is the same as this video




    Hope to help a little.

    Dondan: I was thinking!
    What if.... You make an AIO so thin, but large that could use all the side panel!
    In fact, you could make the radiator BE the side panel! (like this Corsair PC)
    And you could sell it like an accessory that I would obviously buy.

    There would be no way to mount it to the sidepanel, but I like the idea.

    Here is a preview for the socket rentention kits. Keep in mind that the screw driver hole on the top surface is missing.

    Its looking like a real heatsink now!

    Intrigued about the installation order for the heatsink. Seems similar to the noctua type with two metal bars that are fixed to the motherboard, and then two screws are used to connect the heatsink onto the mounting bars. Will there be holes in the fins to allow access to the two screws? Or maybe theres more to the design :)

    What about coating on copper? If price allow it, of course.
    Like this on Enermax T50 Axe:
    I think is graphene, but maybe is something else.

    Dondan has already been complaining about how the price of the heatsink is too high as it is so I highly doubt that the coating will make it any cheaper...

    You should avoid aluminum in the base, as it corrodes in contact with liquid metal pastes. The base should be fully copper

    So the work on my heatsink from my side is nearly done. I don't have any specification on AM4 socket. I think I have to contact AMD for more details.

    Here is a preview on 2011-3 Narrow ILM

    Nice to see it´s done from your side.

    Got any prices from CoolJag ??

    Thought about the demands from Thermalright about atleast 2000 Coolers to get the price you want.

    So you drop it because it wasnt possible to proceed

    I never got a new price from Thermalright. The last message from them (the German middleman) was 10 days ago. I am still waiting but I think it will be impossible working on a project like this with them with such a delay in communication.


    From CoolJag I get 1-2 mails every day. I can feel that they are interested in this project. I think I will get a price this week.

    Edit:
    This evening I send an e-mail to the German middleman company that forwards my messages to Thermalright, that I am not longer interested in acooperation with them, because a project like this can't work without communication.

    I think from an ethical perspective, you absolutely did the right thing. Being in your shoes I would also unquestionably go with Cooljag.

    dondan does the final design includes the ability to attach 120x120x12mm fan like the scythe SY1212SL12H-P (the 4-pin PWM version that comes with the BIG Shuriken 2) ? because they sell it alone if someone email them.
    it will prevent the removal of the large Northbridge and Mosfets big heat-sinks in some motherboards.
    By the way VLP Ram is a must with 120mm fans. (12mm or 15mm)

    Out of curiosity is there still room for a 20mm thick fan, if motherboard permits it, just like the Nexus LOW-7000 R2?

    It is nearly a Nexus. The fins on the Nexus have a height of 16,5mm and on the HSLP- 48 18,5mm. Free space is 19mm but I think a 20mm fan will fit if you bend the heatsink a little, but I don't think you will find a low profile ram that fit under it.

    So there will be all kind of clips and clip holes for all fan sizes 92mm and 120mm (12-15mm thikness) , and the ability to shift the fan a littile in all directions.

    There are clip holes to support 92-120mm fans with a thickness of 12-16mm. And yes you will be able to shift the fan. For some boards it will be possible to use a 120mm without the need of lp ram.

    Nice to hear.

    Do you think its far away with the Kickstarter ??

    At first I need prices. If the prices will be ok I will order a prototype. I think this can take 1-3 month. Then I will test it with a Ryzen 1700X, 7700K and 5820K and share all results with you. If the results are in the expected range then I will take photos, make a user manual, update my website and design the Kickstarter campaign.


    So we have three requirements that can make this project fail: price, profit and temp results.

    For the business benefit point of view I will have a very bad hourly wage on it. So if I can earn $10 (before duty) on each heatsink on an aimed Kickstarter price of under $70 I will do it. So it will be more a present to the community and A4-SFX owners as a big business deal.


    I aiming a campaign in Q4 2017 - Q1-2018.

    Have you think about the guys at Calyos to make the cooler? (at kickstarter too)
    With their tecnology and a fan, maybe it could be possible (and maybe smaller)

    Their fanless solutions work with large and heavy heatsinks, the size of the case. They have no small and light solutions and they rely on building their own cases so non of the technologies they currently have are efficient with cases built for aircooling. That is why you can see that most of their solutions involved their own custom built case and they are pretty heavy which defeats the purpose of a small portable case.

    They develop Loop Heat Pipe Cooling Solutions without fans.
    If Dondan adds a fan, he could make a small system.

    The way I understood it, is that the "loop heat pipe" is only more efficient over long distances. For short distances the normal capillary pipes outperform loop pipes. In the HSLP-48 there is no need for long distance pipes.

    I am not interested in the Calyos solution and I think they have currently enough todo with their Kickstarter campaign.

    You should consider making the mounting kit and the CPU contact plate as aerodynamic and thin as possible so the airflow to the fan is maximized.

    If you have a idea how to make it more aerodynamic please let me know.

    If somebody of you have already a AM4 socket board please help me, because I need two dimension:

    • Height from motherboard pcb to topside of CPU
    • hole pattern of the backplate (M3 or M4)?
