    I finally have some time on my hands to start building in the Streacom DB4.

    See review [H]


    The plan is to go with a gtx1050ti passively cooled. I want to use the front and right panel for the gpu so I am moving the cpu cooling to the left.

    The HDplex Streacom hybrid for the cpu, the holes are slightly offset but the pipes seem to fit nice without forcing them.

    If all goes well stress testing the G4560 should start in the next few days.

    Got it up and running, it's been stress testing 3+ hrs. Got up to 65C fairly quick but it stays there. It is about 18C here.

    yup, that's naked

    Still not sure if I keep it like this or try to mount again because I have 5C difference in the cores.

    Did the psu next, didn't want to go with the overpriced and ripple disaster ZF240 Fanless 240W ZeroFlex PSU. So I went with the trusted sf450, to get it in there I did the following.

    mounted four standoffs on the inside of one of the panels

    I used the thick thermal pad that came with the db4

    psu002.jpg

    Then I bolted the pcb to the panel, the pad got nicely squished against the vrm's

    psu003.jpg

    Very happy with the results so far, cables are a perfect fit

    I think I am going to hook up a buzzer to the fan connector, not expecting it to happen but this way I will know when the psu wants to spin up so it will be a overheat warning

    While I was at it I changed the resistor from the power led, it is no longer bright as a dying sun

    Gpu left, went with a gigabyte, waiting for heatpipes to finish off.

    I have all the parts now to finish the build.

    Glued on some heatsinks just to be sure, I used expoxy mixed with aluminiumoxide. Installed a buzzer to the fanout.

    Heatsinks on mobo, chipset got freaking got

    And I ran out of tim, oh well still need to bend the pipes for the gpu.

    This time I used shims because I wasn't happy with contact between heatpipes and panels

    I found a use for the copper cpu shim, this should keep the vrm's happy

    test fit, looks ok

    Unfortunately I messed up 1 heatpipe, it was damn hard bending them without proper tools. So I need to get a new one:(

    Adding 2 heatpipes to spread the heat

    Luckily I didn't break anything and all booted well.

    I had to disconnect the buzzer because it didn't stop, I think I used a too high of a resistor so the psu thinks the fan is blocked and keeps on trying to spin it up, I'll fix that later.

    Temps look awesome, lid is closed and case is in corner onder a shelf.

    Only one thing I have the gpu overclocked with msi afterburner but, somehow it throttles with furmark, it does boost normal with a game.

    keeps boost @ 1721Mhz

    This was final config before closing up

    If there is no internal airflow, then how much difference does it make to put those extra heatsinks on the motherboard? Do you have a way of measuring the temperatures without and with?

    It's more important than in a case with good airflow.

    Also there will be some minimal convection based airflow. There are holes in the bottom, and the top has small cutouts on the edges that will let hot air out, and then it will draw cooler air in the bottom. Not a lot, but it will help.

    Exactly what Snowdog says, also there are cutouts in the panels itself.

    Here is a 30 mins stress test. I used prime small FFT's for maximum heat. I also started the little render from gpu-z to keep high boost on gpu.

    As you can see, system 55C, PCH 56.5C all perfectly acceptable temps considering you will never get these kind of loads even with gaming. When I started with this build I had planned to drill holes in the top cover for additional ventilation but I am not going to bother with that now.

    Absolutely stunning build Raiju, i had the very same thoughts using the corsair power supply. im having trouble locating the heatsink do you mind letting me know where you get the HDplex one? also could i trouble you for a measurement from the graphics card board to the side panel internallaly (where you have the thernalright VRM cooler) as im wondering if im able to use the straecom heatsink riser that they do.

    Thanks

    Thanks, I assume you mean the cpu blok? They only come with cases, I was lucky and Larry from HDplex had a used one he was willing to sell me.

    This thing is all closed now, next week I am tearing it all apart because I figured out what is wrong with my naked die mount after watching Kyle's video again. And while I am in there going swap to swap out the G4560 with a 4 core. I'll make the measurement you asked for then.

    Thanks for that, im contemplating going with a G4560 as well instead of something like an i5, tried to highlight the measure in one of your images below hope you dont mind. :

    Hi, sorry look a bit longer than expected. That distance is 55mm.
