    would it not be better to move the fan to the left a bit so that the raiser cable doesn't block air flow, or could have have 2 fans ?
    have you tested temps before and after?

    CPU temps OK, the temperature / noise ratio is totally different with the fan 120 mm

    dondan,so I have an ASUS Strix Z270I with a USB3.1 Gen. 2 header. I will be upgrading to the Z370I which also has a USB3.1 Gen. 2 header. Is there an ETA on the "USB 3.1 Gen2 Kit" for the A4?

    As maybe some of you noticed, I had issue with PCI-e extension cable. After contacting Dan, he managed that very fast. When I was waiting for the new one, I had bought some regular PCI-e extension and I have tried adding 4x Noctua 40mm fan on the top cover and to do a small adjustments to my Asus Z270i motherboard (to fit the LP53 heatsink with better positioning) and m.2 SSD (960 Pro). Now when the new original is home, I have also made some pictures of i for you.

    Here are the photos of the result one by one:

    1) Z270i heatsink removed and replaced with RASPBERRY Pi RB-Heatsink (I bought 3 packages - in each package was 1x 14x15mm and 2x 8x8mm (height is 5mm for both) plus they already have the heat tape on them). The smaller ones fit exactly on the chips that original heatsink was.
    - The small ones (8x8mm) fit exactly in that small space - I had to apply them with the tweezers and apply small pressure on them.
    - You can also notice how close are the endings of he LP53 copper base CPU heatsink.


    2) Here it shows the positioning of the LP53 cpu heatsink. So the airflow from Noctua PWM fan goes to the top of the case.



    3) m.2 SSD adjusting with rest of the RASPBERRY Pi RB-Heatsinks.
    After running 2 stress tests to SSD to find out how are the temps, it never went above 54°C. I in idle temps are usually around 40°C (ambient temp was 20°C) (link to my previous post with testing: link)


    4) Now the main thing, 4x Noctua 40mm fans

    Attachment view - inside + outside



    2x fan in CPU area



    2x fan in GPU area (for one fan, I had to use extension that was in the package)


    Top view on closed case - you can see the Noctua fans



    Final word and notes:
    - Noctua fans are attached thanks to the slim zip-ties. Silver case is a plus, because you can scratch your case a little when installing due to the bending them and cutting them.
    - Temps in idle for CPU are usually around 30°C (ambient 20°C). They are very quiet but it depends how you set Noctua fans speed in bios.
    - My GPU supports 2 additional fans (Asus Strix GTX1080 OC), but but minus is that you cant control them. They will just start when gpu hits the temp limit (usually 55°C). If I have missed the possibility to set them and I am wrong with this one, please let me know.
    - On CPU, I used Arctic MX-4 spreaded all across the heatsink (very thin layer).
    - As you can see, further cable management (both, for fans and custom psu cables) would be required, but it still runs alright.

    Feel free to ask any questions or if you have any suggestions, they would be welcomed.

    I have managed to bent the PSU cable different way - see red line below.
    Than you can install 40mm Noctua fan there (see my post above)




    PS: Koukám že tu je někdo další z česka

    I suppose it is too late to change the design, but i do think a proper dorsal cooling solution would aid the A4-SFX's cooling significantly

    @Synomenon: I have no ETA for the USB 3.1 gen2 Type-C cable. I will wait til we see more boards with the internal header.

    dondan Thermaltake PCIe extenders sure are quality: (lower your volume, Linus screams a lot towards the end of the video and it's annoying)

    Different than 3m riser will not fit into those holes in case. 3m riser has screw holes more distant on both sides than other regular cables. Approx 10mm on each side.

    But you can go to your local hw store and ask them to make small metal stripe with 4 holes in it. 2 for case and 2 for new cable.

    I have a sample here from the company that makes the premium riser for Thermaltake. This riser has the same mountpoints like the 3M one. So I think the Thermaktake riser can fit :)

    Hi everyone, I'm here to present you the all new


    :punch:
    >>> A4-SFX-TURBO <<< :punch:



    Or how i've managed to drop the temps on my 22 cores cpu by -18ºC for 15,9$ + shipping costs
    (don't expect any shiny polished solution :LOL:)





    After eight months with my 22 cores XEON E5-2696, I have realized that I had to do something with the high temps.

    This CPU behaves like two. When you are gaming or working with any app, it hardly gets 70ºC, but when I use it for 3d rendering, It rises up to 99-100ºC after just some minutes.

    I think that the max temp that it can handle without throttling is 105ºC, so it is going hot as hell.

    After trying MANY fans and heatsinks, I've realized that the best combo was the Dynatron T-318 with Thermalright ty-100 fan. It is the only combination that dind't lead to +100ºC while rendering (yes I have tryed noctua fans, falcon and thermalright heatsinks, gamersotrm fan, etc etc, and none of them can handle this cpu).

    In august, reaching 100ºC was very very easy so I used to have a hair dryer in cold mode to cool down the cpu very quick if required (it is able to drop temps drastically if you put it directly on the fins in the dynatron side, even from 100º to 75ºC in a minute) so I thought on trying to make some kind of wind tunnel like the ones on FE GPUs, with small fans like the ones on the pictures below that acted like an integrated "hairdryer".



    So, the first idea was to put four 40x40 fans in each side of the dynatron heatsink in pull configuration, leaving the main fan in the middle in push configuration, but ty-100 is too wide, so 40+100+40mm didn't fit.


    That's why I tryed with the noctua NF-A9x14 + 4x 40x40x10mm fans in the following scheme that fits perfectly:



    [​IMG]

    [​IMG]

    After that I tryed with this configuration:

    TY-100 + 2 x 40x40x20mm fans.



    [​IMG]

    [​IMG]

    After tryng both configurations, ty-100 fan + 2x 40x40x20mm fans was definetly the one that presented better temps as the ty-100 has been better than the noctua in all of my tests.





    So the next step was to select a fan height.


    There are a lot of small and inexpensive fans out there but most of them have a fixed voltage, so they always run at maximum speed. After some researching I discovered a very versatile format that has PWM capablitities.

    I have tested these three fans with three different heights:

    · 40X40X10mm Everflow PWM

    It was the first that I purchased, I thought on putting towers of two of them to achieve double of air flow, but it didn't make any difference and they sound like bees at full speed.

    · 40X40X15mm Evercool PWM

    This ones are by far the most powerful of the three, and they fit perfectly on top of the dynatron leaving 5mm of room between the case and the fan, but they are extremely loud. If you want the highest performance these ones are the best by my testing.

    · 40X40X20mm Evercool PWM <<< the one that I've chosen

    It is by far the most silent of the three, although It can achieve the same performance as the others without speeding up so much. It is taller so the propeller is bigger and it needs less speed to move the same amount of air. Even at full speed it is definetly quieter.



    So the last step was to create an air duct, to ensure that the air pressure isn't lost through any hole, so I made one as you see in the next picure with some plastic cardboard, a pair of scissors and double sided tape.



    [​IMG]


    [​IMG]

    I used the same fan curve for the main ty-100 fan as I had before, but for the other two I configured them to be at 30% all the time, till the system reaches 70ºC, when the fans speed up at 100%.
    That ensures that most of the time, even while gaming the computer should be quiet, but while rendering the turbo would turn on keeping it cold.


    And here the results while rendering (ambient temp 30ºC):

    Open case:

    TY-100 + dynatron T-318 ----------------------------------------------------- 100ºC

    TY-100 + dynatron T-318 + 2 x 40X40X20mm Evercool PWM ----- 82ºC - 18%

    Closed case:

    TY-100 + dynatron T-318 ----------------------------------------------------- 100ºC (the same as opened in testings, but I used to open it for precaution)

    TY-100 + dynatron T-318 + 2 x 40X40X20mm Evercool PWM ----- 87ºC - 13%


    It is a 13-18ºC gain!





    Using this kind of fans in this case is a joy, so try them and let me know your results!!

    One idea for the vendors if they are reading:

    [​IMG] [​IMG] [​IMG] [​IMG]

    For me It's the most obvious high performance and silent cooling solution for the A4-SFX

    [​IMG]


    [​IMG]


    [​IMG]

    [​IMG]

    [​IMG]

    The radiator is 20mm in thickness, the fan has the dimensions of the ty-100 and the cpu block has 12mm of thickness (it doesn't need more as the pump is not integrated).

    There should be some screws or clips to fix the fan to the mounting structure


    maybe cooler master wants to make it, as they are entering the sff market with this:

    The concept is very similar, although I propose one bigger fan and a high performace pump outside of the radiator to make it bigger and thinner.

    Thank you so much for sharing, that's very useful for people who want to build an X99/X299 system in the A4-SFX. Did you consider trying the Noctua NF-A4x20? Perhaps with 2 of those and an even better duct you could drop temperatures even more.

    Great proof of concept. You've added an output directly next to an input, and it worked. This is why I think reversing the PSU fan is a good idea to test! (Hint, hint, somebody try it!!!)

    Your cooler concept is basically dan's cooler concept, but he uses heatpipes because they are more space efficient. The heatpipes are little pumps :) A big water pump couldn't fit in this space. Dan's heatsink will change the game when it arrives!

    wouldn't reversing the psu fan take air from the top of the case and push it out the side ?

    Hi all. I received my case today which i thought was a SFX -v2 but it turned out to be a SFX-v1. Purchased from overclockers as they had some in stock and was told by them it was a v2 i would receive. narnar. Ive had to RMA it back as it ended up being a v1 inside. Was so gutted.

    Last month I send 50 cases to Caseking and it looks like they send some cases to OverclockersUK (Caseking and OCUK are one Company). These 50 cases are A4-SFX v1 cases that I had in stock for reclamation. But the reclamation rate was so low that I sell it to them. The original plan from Caseking was it to make a prebuilt system under the label of the overclocker 8pack. It looks like the ship some of the cases to customers that preordered the A4-SFX.

    It is impossible that this is a V2case because they are still in production and will arrive in January 2017. As I know from a private message that I got from a OCUK customer they add a small white sticker on the case to easy scan this cases for the shipping process. On this label they write A4-SFX V2, but this is wrong on the carton is printed that this is a V1 case.

    Sorry for that trouble but it is not my mistake.

    Regards
    Daniel

    I had an order for what I believed to be a v2 with OCUK, in fact under instruction I pre-ordered as I missed the v2 kickstarter. I managed to find a v1 a couple of months back, but left my OCUK pre-order in-place so I could later upgrade to the v2. Well, I just got my shipping confirmation for v1... not really pleased about that. I think this could have been handled better in that it should have been clearly confirmed what was being shipped. Now I am stuck with a second v1 shortly. If anyone in near Sunnyvale California area wants a v1, let me know. Also gutted that a v2 will never be in my future now.

    Have a talk with customer service on their forum? They will either refund you shipping or provide a pre-paid shipping label.

    That was me who sent you that email :) They are currently investigating the white label saying that they didn't put it on OCUK at their base of HQ. Its a bloody nice case the v1 its a shame to send it back. I just hope i can grab a V2 as i really wanna get my new rig built asap.

    Has somebody successfully mounted a case fan above the mainboard? I bought a Akasa 80x10mm fan and I could need help to stop it from colliding with the PCIe-Rizer.

    Uhm guys aesthetically speaking which 1060/1070 gpu would look awesome with the window panel? Don't mind the performance a 1060 is enough for me already actually and a 1070 is an overkill. Thanks guys!

    but now you need to wait probably 4-6 months before you get an almost identical case :(
