Fanless PC

[nathancarlk]

Okay, I'm going to start off saying I know this is a very impractical build and there's no cost per performance whatsoever. Now that that is taken care of, Fun Time! So i've seen some really quiet builds, and my own pc is built around BeQuiet! And I love thier products.

I found a passively cooled 1050ti, and was going to throw in a psu like bequiet or the corsair that has no fan running at idle. Throw a m.2 in there. I also found a cpu cooler that has okay heat distribution just off of computer case airflow. I'm not going to have any case fans running, so the heat is going to have to rise out of the case on its own.

So I was wondering your guys' opinion on this, I was thinking of doing a ryzen 1600 and downclocking it. You guys have any suggestions. 

 

As for my real pc: 1080ti, 6700k, so this is simply for fun.

Would be really cool to make like an "all case" aluminum cooler that filled up the whole case and had this open top where the heat could escape

I was assuming I would have to really open up the case in certain areas just to allow room temperature to flow in and out on its own. Might have to test it in my dark, cool basement if I have issues. : ]

those "passive" 1050ti's are designed with case airflow in mind, which yours wont have

Yeah, I'm quite aware of that, the cpu cooler is designed the same way. It obviously not going to work any load for a long time. And as I said before, it's all just an experiment for fun.

IMO:

1. Get cheapo mATX case or ITX when the boards will finally be avaiable.

2. Strip down it of side, top and front panels.

3. Cut to size of mobo tray.

4. Since on AMD there is no real heat-cores connection... you'd need to get this 1600 to 1.0v or sth

5. Get flexible PCI-e riser and mount GPU upwards

6. Done
 

[Zubkover]

BTW, are you going to strip the PSU fan too? Or the "trashcan with one fan" is plausible?

 

also: I'd actually rather think of getting a 1050ti and slapping some morpheus or other riddicolous 3rd party cooler on it.

That was exactly what I was thinking!!! Woot someone else thinks i can do it!

Nope, Corsair and BeQuiet! both offer ones that dont spin on idle. Was going to put one of those in there.

Mate. I currently cool my 9800 GTX+ with 14cm Noctua fan, and I also redid stock AM3+ D3 cooler to accomodate 14cm gray godness.

WHO DO YA THINK I AM?!

[Zubkover]

Soooo... I'd suggest this "battleplan" of : Grabbing old-style case with PSU mount on top.
That would mean if heat rises it'd also trigger the PSU fan at certain point, which would work as an exhaust.

Then just making sure, that all the vents beside the very bottom near GPU are blocked off... and voila!

fanless psu's are available, also dyson make a bladeless fan. I wonder if you can use this tech to get a gentle flow of air. otherwise its just thermal conduction air movement....good luck

[jools]

dude what part of fanless pc did u not understand

[Zyndo]

@nathancarlk This will not work. heat will not dissipate quick enough if left merely to its own devices. temperature will build up over time and result in thermal shut downs since the heat has nowhere to go. I know you expect the heat to just radiate out on its own and flow out of the case on its own, and it will do this, but not nearly at the rate at which its building up in your system. if you bought some really low power components and did low power things on the system (such as basic web browsing) then maybe you would be fine... but otherwise its just not going to happen.

Just get an open air case like the thermaltake core p3 or p5.

Antec made a couple of tiny mini-ITX cases that did that. The CPU heatsink was built into the top panel and would dissipate heat through the case itself. I think this was the 'ISK' or 'NSK' series; the ones that only took flex-ATX power supplies.

You didn't specify a budget, so here's an idea. No moving parts, big-ass cooler.

He said Ryzen 1600 tho.

[dude49]

Very intruiging idea. I think I saw something similar on a DIY channel on YT, where the guy building the PC made a custom all-aluminium case, to which the cpu coolers were attached. He even fitted a CPU cooler to his gpu. Quite interesting for a silent build. ( BTW, I recommend Fractal Design R5s, windowless of course; they have great sound dampening)

You might consider a Seasonic fanless psu. SeaSonic SS-460FL Active PFC F3 is one such. Only thing is that they must be mounted to exhaust upwards in order for the convection cooling to work. 

 

It occurs to me that a case with a top grill might work reasonably well. Just orient the cpu cooler tower so that air flows upwards across the widest surfaces.

 

If one is contemplating a psu with active fan management, why not a gpu with same? A number of modern gpu do not spin their fans until they start to get fairly warm. 

 

Depending on timing, Ryzen laptop cpu are due sometime later this year. One of them may offer a lower TDP.

The Dyson "bladeless" fans actually do have fans. They are in the base and drive the air out of little vents around the inside of the "ring".

I know. I still picked the 7700 because that fanless cooler doesn't have mounting hardware for AM4. I don't know of any that do.

Ever heard of zipties?

I won't recommend some janky-ass DIY solution when something isn't supported.

 

If you didn't notice, this is a goddamn heavy CPU heatsink. Unless OP intends to mount the motherboard parallel to the floor, this won't work. The zipties will not be enough to hold the cooler in place if the motherboard is normally mounted. I think that unless you go out of your way to find a non-standard case where the motherboard sits on the 'floor', it's a stupid recommendation. Zipties are not enough to hold this cooler in place when working against gravity.

The case I recommended is standard. The motherboard mounts on the motherboard tray perpendicular to the ground.

Well - in case you didn't get it - yes it was a joke.

 

Nontheless - AM4 mounting isn't MUCH way off from AM3+/AM3/AM2/AM1/FM2+/etc. , so drilling holes in upper mounting bracket of a cooler shouldn't be all that hard, especially when on all AMD boards you have AM4 CPU cooler backplate included.

 

And yes, I'm THE DIY man, who assumes every man on the earth SHOULD know at least how to handle and oparate a drill without hurting himself...

... when you account for the fact that I, as a student, make my pancakes with usage of power tools it seems rather funny tho.
