Is passive cooling a good thing?
>>52667810
yep, for vegetables
If you can get the temps you want using it, sure, it's good for sound and in mobile devices it's good for battery life (since you don't need to worry about powering a fan).
Are there any <20dBa fans for i7?
>>52667810
I passively cool my 9800GT
works great
>>52667810
Sometimes.
Just not in laptops. At least not laptops that cost more then like $150.00
For instance $5.00 raspberry pi zero? Fantastic place for passive cooling.
That GSkill ram is not seated... Seated Ram THread...

I like the concept of this coolers technical design.
But if I'm going to play muh gaymes. How can I fit the graphics card in to the PCIe 16x channel?
>>52667810
If you can get away with it, yes. Less moving parts is always good. Personally, I'd love the background fan noise I've been living with for 18 hours a day for the past 20 years to just go away.
>>52670181
put the desktop in another room, run the power cables and a USB hub through the wall to your desktop
>>52670073
It's not meant for gaymen machines.
>>52670210
I'm sure the guy in the neighboring cubicle would love that.
>>52667810
Depends what you're cooling with it. I wouldn't passively cool anything AMD.
>>52670073
Most motherboards have more than one PCIe x16 slot. Also what >>52670219 said.

Give me one good reason why this wouldn't work
Depends. If passive cooling can maintain your processor under ~70°C even under load then go for it.

There have been fully passive computer builds in the past, but studies show even just one fan can substantially decrease temps.

You know, I know galvanized steel probably isn't the best heat conductor, but I wonder if it'd be feasible to use the water pipes in your walls as a heat dump.
>>52667810
>Is the lack of unwanted noise emission a good thing?
Gee anon, I don't know.
>>52670282
You want fins on the outside of the case so it can actually dissipate the heat effectively. Pic related is an example of just such a case.
Is it possible to make an ok gaymin rig with passive cooling?
How does the space station dissipate heat? Shouldn't the place turn into a giant space oven since vacuum is a perfect insulator?
>>52670419
they push all the heat out into radiators
>>52670367
probably, but such a setup would be silly
>>52667810
Unless you're playing games passive cooling seems fine these days.
I use it for my low powered server. The fan never turns on.
Asrock Q1900 series
Typical temp: ~40C
>>52670419
How does the sun dissipate heat? Shouldn't the thing turn into a giant space oven since vacuum is a perfect insulator?
This is pretty intriguing: https://www.youtube.com/watch?v=9DyUitTVWlw
I play games on muh rMBP sometimes, and the intel iGPU gets unstable even at not-very-hot temperatures. Designing some kind of water cooling solution that sucked onto the bottom case (since it operates as a heat sink AFAIK) would be pretty rad.
>>52670232
no problem for AM1 socket CPUs
You guys realize that all this heat you're generating ultimately is dumped into the Earth and directly contributes to global warming, right? Any computer that generates heat needs to be banned in the US.
Ive just put a new cooler in my server and tried it out without any fans.
Temps are around 50° without fans.
35-40° with fans on.
I like it without fans.

>>52670419
>What is radiation
the design with the gtx 9xx series how they just sit fanless for most of their operation makes me want a computer that's completely fanless
>>52670695
>Any computer that generates heat needs to be banned in the US.
So, all of them?
>>52670460
I recently bought a D1800 and the thing doesnt work at all.
Also integrated CPU is a neat concept. Would be cool if there were some boards from AMD with that too.
>>52671671
you can get pretty much the same results and a similar TDP with AM1 boards. I saw some being sold for just 30€ and the cheapest AM1 CPUs with 25W TDP are around that price too
>>52667810

You haven't been looking hard enough

As far as I'm concerned, this is better than the quad-core Celeron boards because it has SATA3 ports and an integrated mini-PCIe socket. Shame about the x4 masquerading as a x16 slot.
>>52667810
yes

>For use with CPUs up to 150W+ (fanless 95W)
>>52671880
>Fanless 95W (varies depending on chassis airflow)
i.e. You better have a fuckton of case fans and don't blame us if anything catches fire. You aren't cooling a 95W CPU with zero airflow and a heatsink that size.
Buy a vacuum case. Vacuum is a perfect conductor so it keeps your PC cool, no fans required.
>>52671933
vacuum is actually almost perfect insulator.
>>52671979
Exactly. It traps all the cold inside your computer.
>>52671838

i had no idea
the biggest hardcare online store in my country doesnt have those
do you also know about low consumption PSUs for this kind of PCs ? somehow the cheapest i find is 15€ for 500W and both lower and higher than that cost from 20€ upwards
>>52672049
I'd rather find a 24-pin to AC adapter to plug in a typical laptop external power brick.
According to the manufacturer, the A4-5000 only consumes ~15W at load.
>>52670695
This applies to every human and electronic or mechanical device that generates heat.
You dont want global warming do you? So pull your weight and kill yourself.
>>52672084
can you say that with other words? english is not my native language.
also i know a guy who got made a "gaming" PC with an A4 processor wich for me doesnt make much sense from the price to performance point of view. anything lower than A6 or A8 doesn't really make sense you can just buy second hand PCs for the same price or probably better
>>52670695
what generates more heat? your phone, your PC, or yourself, with 37ºC at all times?
kill yourself, save the earth
>>52667810
>he hasn't upgraded to superior copper sponge technology yet
>>52672274
The A4 integrated board is for light-weight or low-energy consumption (aka 24-hour use case scenarios) builds, not for gaming. Nvidia cards won't work on it (PCIe x8 minimum) and only a few AMD cards will work.
What I meant by the power adapter is that you can find a 24-pin ATX power connector that has an adapter designed to plug in a typical laptop AC power cable to power the computer running the A4-5000. You won't need anything more than 95W for a typical A4-5000 ITX board build.
>>52672247
>>52672307
The heat produced by humans is part of the cycle of life and is in natural balance. The heat produced by technology is unnatural. It disrupts the balance.
>>52672337
Airflow would be shit through that.
>>52672381
>airflow
utterly prehistoric
>>52672364
oh thats amazing. im looking forward to buy one then
>>52672337
I could actually see that working pretty well in an open case/frame.
>>52672417
that's the whole pc

>>52672415
As long as you're planning to use it for 24/7 shitposting on a Nepalese shadow-puppet forum or seeding horse porn, you're fine with it.
Gaming? Don't use an integrated CPU mobo.
Find a really small case for it, too. Like the Inwin BQ656T.AD120TBL (120W PSU built in) or Mini-Box M350 (you'll need to find an adapter for the laptop power cord, but the manufacturer also sell those).
>>52672337
Have fun cleaning the dust out of that
>>52670462
> what is plasma?
>>52672464
oh yeah its just a cheap computer for sale, with the main thing going for it being the prize. also is this a good price for that kind of 24-pin connectors? are there any other competent brands than PicoPSU ? and why is the dollar so pricy nowadays
>>52672522
The surface of the sun is a liquid.
>>52670462
isnt the sun exactly that?
>>52672367
You are very skilled at saying dumb shit for attention. You should run for president.
>>52672525
That's not the right connector to start with. You need to find a 24-pin ATX connector, not a 20-pin connector. I'm pretty sure Mini-Box sells the right adapters for the case. If anything, the Inwin has a 120W PSU already built in, so you don't have to worry about finding the adapters.
>>52672445
>check Silent Power's website
>it's some hotel advertisement page
Guess their idea didn't work out ;)
>>52672561
no, its plasma.
>The sun's photosphere is often mistakenly referred to as the surface of the sun. In reality however, the sun's photosphere is only a "liquid-like" plasma layer made of neon that covers the actual surface of the sun. That visible layer we see with our eyes is composed of penumbral filaments that are several hundred kilometers deep. This visible neon plasma layer that we call the photosphere, and a thicker, more dense atmospheric layer composed of silicon plasma, entirely covers the actual rocky, calcium ferrite surface layer of the sun.

Actually, further reading seems like it turned out they were a crowdfunding scam all along.
>>52670462
Radiation.
>>52671838
I almost bought that. got an Athlon 5350 instead. Looks like a good Plex server.
>>52672667
Nope, more recent evidence is making it more and more likely that the surface of the sun is literally a liquid. It's an active field of debate.
I've got a Packard Bell computer with Win3.11 from the 90s and it's almost entirely passively cooled. The PSU has a small fall but other than that it's totally fanless and even though I've never cleaned it out there is 0 dust.
>>52672695
just like the fact glass is a liquid
>>52672525
I use a 20pin pico psu with a msi am1i + 5350. Running stress tests on it it pulls 25-30w from the wall. I run both my monitor and pc from one 12v 5a brick
>>52670462
Vacuum is not an insulator, that's why.
>>52672389
Teach me, how the heat escapes from the sponge?
>>52672607
what about this thing? i think i have some laptop power cords so i would just need some kind of adapter i guess? or can i just plug it in the thing?
>>52672909
thats great but does the stress test also run graphical benchmarks? because half of the chip is essentially Radeon R3 graphics right?
>>52673111
Air flow
Google metal foam for details
>>52672364
You can use any GPU you want with modification or an adapter
>>52673153
Well, that's what I thought.
>>52672945
It is an insulator.
>>52673168
The other anon's a retard. Air flow-to-surface area is the main reason why metal foam works so much more efficiently than a standard heat-sink. You still need air moving through the foam to dissipate the heat.
>>52673207
Never heard of this metal foam radiator till I saw that pic, but it doesn't look like it'd be very easy to move air through. What does an actual deployed solution look like?
>>52670367
linus has a video where they do this 7 pc's hooked up to copper in the room and radiator outside build, well its a playlist.
Anyway it end up working and cooling the pc's and the room by an entire half degree celcius more then with regular watercooling.
So possible, yes. But practical ? no
