/diy/ - Do It Yourself

[Making the CPU shut the fuck u(...) No.744921]

I have been a pc using it for years, but today 15 years after hearing the noise from the fans from the case im pissed and sick of hearing it, i already:

-bought a heavier R4 "sound proff case"

- bought some big ass fans that can be set to spin slower (5v ,9v ,12v) and silently

-keep the fans as clean as possible

-make sure all the air gaps are closed and keep everything so thight so it can vibrate

-bought a huge fucking noctua heatsink for the proccesor

-left as few fans as possible (3, in, out, proccesor heatsink and another 2 that come in the videocard, those are actually very noisy)

But all this has reduced sibrations in around 40% but this is not enough, the sound ,making me crazy i also found that by removing the little holes that protect my fingers from the fan also help to make it more quiet

My 1st idea here is to put this shit below the ground or behind a wall, heck , im even thinking in putting this shit inside a wood, crystal or even a metal case so it can act as a heatsink for the case, it heating up might be a problem so i come here to ask for any feedback to how to finally make my cpu shut the fuck up , an ideal sound would be to barely notice its on

Passive cooling is what you need. Very possible, but usually takes up a lot of space.

i do know its also very expenssive to mantain, you haave to change the water every 6 monts or so and ots a bit expenssive to do it, i was thinking in a less expensive and "passive" solution

>Change the glycol every 6 months

Why? I think he meant a bigass heatsink like pic related, no glycol. You are thinking of liquid cooling

[Anonymous No.744934]

They have silent and quiet PC forums where OP can learn vast amounts of quiet-fu. It's too complex a subject for one thread.

BTW changing coolant every six months is stupid. I use automotive long-life coolant and never change it unless I drain a liquid cooled PC for modification or repair.

The pitiful heat output of any PC isn't going to degrade coolant designed to survive years of use at engine operating temps. That problem was solved long before personal computers existed.

they who?

[Anonymous No.744940]

Let's work this out logically... Are you annoyed because the computer is running continuously and it's noisy?

Is this a gaming machine? Because it sounds like it is.

The solution is then, to not run your gaming machine constantly as your regular computer for communications/internet/porn/etc. and operate some other machine with a better power profile that you can cool passively.

I had this exact problem years ago, and that was my solution.

[Anonymous No.744956]

So you're a pc using yourself?

[Anonymous No.744959]

the basics are to build low power (i.e. not overclocked SLI GTX480s), use huge slow fans (like 180mm/700rpm) and SSDs instead of spinning disks. if you gotta have dem terabytes, suspend your HDDs on bungee cords.

[Anonymous No.744967]

Try unplug all fans first!
Why? You now hear other f.. noices like hdd.
if that is oke level of noice, then do something about the fans.
try counter noice like putting on music or table waterfall. My sollution eventualy was to by cool running laptop asus x75a.
also kill background running software
check cpu load
silent running fan
acoustic pack rubber foam
Put rubber under pc for fibration

I have been a fan of "quieter" PCs for a long time now.

if you don't want to spend a lot of money then just build a mid-level system, get a can controller panel that lets you adjust the fan speeds and turn the fans down 25%-50%.

the special fans aren't really much quieter than the normal name-brand ones, IME
the special PC cases aren't really much quieter than the normal ones IME
a totally-passive system would be nice but isn't necessary. nor is water-cooling, if you just want less obnoxious fan noise.

SSDs do get rid of the hard drive noise but the main thing you hear is the fans. and if you turn them down just 25%, they make much less noise.

[Anonymous No.745535]

>>744936
SPCR would be your best bet.

But is basically comes down to; passive cool as much as possible, use big slow fans on things you can't passively cool and avoid mechanical HDDs as much as possible.

[Anonymous No.745541]

Stop using a stupid voltage divider bullshit for your fan control.


Your motherboard almost certainly has pwm headers. Get fans with a good range of speeds and db levels and put those in. I hlgot 80mm coolermaster fans because I have a mini itx case and that's the biggest i can fit.

They go from 12-45 db. They are usually whisper silent, cant even hear them. The bluray drive is much louder during high speed reads. Ifbi start gaming it might turn up, I don't know I haven't even heard it turn up high.

Pwm fans. Set your bios to auto calibrate them, or figure it out yourself, set to quiet profile. Get a uefi or stx psu. It will stop its fan if it doesn't need it. My htpc is quieter than mynps2 or Wii or old bluray player, and that's with 80mm fans.

Passive cooling is fucking expensive, and water cooling is not silent unless you stickth epump and reservoir in another room

OP have you considered a split system water cooler?

also throw away your giant heatsink. they're worthless.
they don't mount properly and always pivot off to one side meaning you have a tiny sliver of thermal interface area and they damage motherboards.

>>744923
passive cooling is bunk. its suitable for like a geode or a centrino. not for a cpu. those passive coolers get hot.

>those passive coolers get hot

How exactly do you think passive coolers work?

[Anonymous No.745549]

>>745548
they're fine for office clients. for a gaming PC running it at 60C and having no ventilation around components that expect cooling like voltage regulators that are laid out to have air blown over them from the stock cooler facing down is a good way to fry a motherboard.

my core2 doesnt get over 40C with a stock cooler. installing a cooling system worse than stock is a terrible idea

[Anonymous No.745568]

Water cooling

Passive CPU heatsink

Fanless/semi-fanless video card (GTX750ti)

3rd party GPU heatsink

I've done the above except water cooling. Stock fans are often noisy bastards.

You know how convection works, right?

And that most ICs are rated to 105, right?

[Anonymous No.745602]

>>745597
105? I'd sooner believe 85. Not the other poster but cooler is better for longer life.

PWM fans are annoying as fuck. There seems to be no way to set the hysteresis; I'd much rather have a noisy fan that makes the same noise the whole time that one that goes oooooOOOOOOOoooooOOOOOOOOOOOOooooooOOOOOOoooOOoooOOoooOOOOOOOOO.

Straight from the horse's mouth, the Haswells have a TJunction of 100 degrees. (Intel does not make available TJunctions of chips that have heat spreaders, but it's all the same silicon).

you cant rely on convection currents to keep something at room temp are you out of your mind?

if you think keeping components running as close as possible to their operational limits is a good idea then you are a dumb idiot

>letting your computer overheat rather than keep as cool as it needs to
Get a motherboard firmware update. They probably patched that for whatever you're running. Never had that happen.

Junction temperature is always maybe 20-30C higher than what the on-board temperature diode measures.

>Your motherboard almost certainly has pwm headers.
Yea but they suck, that I have seen.
If you buy a brand-name mobo they usually have a fan speed control program bundled with the mobo drivers.
The problem that I have seen several times with my own PCs is that if you use a mobo+fan control software, the fan control software always crashes after a few days and then the fans default to running wide open until you exit the fan control software and restart it. So it ends up being a hassle.

If you get a fan control panel with knobs on it,,,,, you adjust them where you want them and they never need readjustment again, unless you get overheating symptoms.
Problem is that I tended to buy Zalmans, and they seem to be gone now... :'(

Why are you running software? Just let the bios handle it.

I guess this is what I get for only buying enthusiast motherboards...

I have a completely fanless Bay Trail build and even it is too fucking loud, due to the mechanical hard drives, if I'm being anal and it's sitting on my desk. Your best bet is to just go totally silent (no moving parts) if you really insist on silence, there's really very little in-between in my experience. You either get performance with some noise or you get silence or you get jet engine (servers/whatever)
