ok guys, i remembered there is a poll asking if you guys leave ur pc naked, which mean u opened the casing, 4 better cooling purposes & easy access i suppose.

but there is one article i read in the newspaper stating that opening your pc's casing doesnt actually help much on the cooling part, says its broken the way the ventilation or watever it means.. and cooling effect will be worst than adding fans inside.

and the casing cover actually is the last line of defense for blocking all those radiation frm those component inside.

so wat do u guys thnk? true or false? or "h*ll, smoke is bad 4 health but i still live by it..so wat should i care?"

Depends on what casing u have....if u have a casing that have a proper fan and ventilation path, opening it can disrupt the cooling. But if u have a cap ayam mini-atx casing and an OC GC and proc...u better have it opened and put a table fan to it...

if u open it and put a big fan blowing to it..it's good ...but the dust..

It's noisy.

lizard and other bigger insects might crawl inside and reproduce!

Then one fine day after a long weekend, you have problem starting your pc~

real experience~

wah, so terrible ah? well, lucky my pc is not on the floor, its actually on my table..

Next thing you will see is spider webs.

still ... lizards can crawl...

sometimes, they do nasty things in your casing... sigh~ those were the days.

by the way, also look out for the dust...

Added on January 20, 2008, 12:02 pmi think spider web also got last time.... but it's so dusty until i cant recognize which one is dust, which one is spider web.

if u hardworking...then good lor,put a big fan..if u lazy then dust...

I always open my case lo..Haha...

So far dust ok lo..be rajin..clean everyday:P

I put my hdd outside so need take out the s.panel...

i;ve experienced when i try to test my old pc.. running or not.. suddenly the pc *boom* at PSU area when i try to switch on.. then i check at the PSU, ants r nesting there~ damn..

actually, it doesnt matter if u open up your side panel or close it. if the insects are attracted to your casing, there's not much you can do about it.

you can however constantly keep your workstation and your casing clean. That's very important if you plan to keep your casing opened.

ok, i'm a lazy fella, so my pc lying there collecting dust with d case open..d*mn.. maybe 1 day need open it all n giv it a clean..but so far lucky nothngy go/nest/breed/watever they do inside la..

well properly enclosed casing with good air flow and dust filter can prolonged the life of the components and keeps the part look new even after years of service.

adding some fans and grill might help the air flow, but wat u mean by dust filter? thought cleaning is the only way 2 get rid of dust...

Well i keep my sidepanel open eventhough i have a fan for my sidepanel...constant cleaning is required tho..

Yes I have to agree, open casing is giving better airflow but dusty. I cleaned my pc every two days with vacuum, just suck out all the dust.

And, open casing is providing fresh air while smoking is providing nicotine and tar =P

but newspaper article i saw saying tat open side panel is not gud 4 air flow?

dun trust newspaper article...

newspaper article is for newbie , correct me if im wrong..

i am oredi experience this thing... my hardware is assemble without use any casing... the tmpreatrure is excellent...

but now i use casing ler bcoz my mother mad at me... hahhaa

This post has been edited by amd_hardcore: Jan 20 2008, 07:28 PM

last time i tried, not so much diff in terms of airflow and temperature. of course, no stand fan beside the case. just open the side panel for several days, and monitor the temperature. no diff in my case

but turns out some cases at my college, open case will result in stealing RAM!

you don't want to be like fella don't you?

stealing hardwares from inside opened case are really common in my campus last time. but now, no such case happened anymore so far.
must be really hurt if ur performance rams got steal moreover by some noob~!!!

aiyo, so greyish and brownish

close case is a bit soothing to the eyes when looking at your CPU. open case, especially both side panels, looks like rangka already

LOL sniper69, is that even yours?

as for me, stealing internal hardwares may be a bit problem coz i never off my pc while in college. so if my side panel is open, they need to switch off the pc 1st then only take out those stuff. that will take some time, or risk getting shock (and later damage my mobo also lorr)

, no le... one of our friend here...

anyway...
mine to... but he cleverer... he actually swapping his 128MB with my 512MB module ..., actually at first glance, nothing really happen because both module same double sided until i think something about my system... really damn slow ... damn, my friend's a backstabber

LOL..and i thought thats urs cause i thought you are running everything solely on the mobo tray

Well, thats the bad thing about running a naked/without side panel rig. Especially when you are running on expensive stuff...

wow.. my case not tat worse la.. its like dust a few inches already..haha.. time 2 do ur CNY cleaning
liao la bro!
but ur fren clever also, he "swap"instead of "steal" , did u got ur RAM back afterwards?

Mengaku ajelah its yours hahaha. Anyway is that really happend ? How did you know it was him ? From his ram ?

with casing will improve temp with proper air flow and fan... but not for health, i think with or without casing wont make us healthy or not...

yes, got it back...

nah, it's not mine... - not mine

yeap, happened... how? because on the other day (before it was actually happened), this guy asked me about RAM, why he wanted to upgrade and so on, but no money..., he's not a very close friend though, but still a friend aight, same campus, same hostel , lucky for me... he too running on naked (not naked as mine, but opened side panel)...

Not using any casing is better for me.

-Dust???? It can be cleaned.
-Air intake?? there's always air running.
-Messy?? Try to reduce all those unwanted wires,sleeve,or use cable tie.

talking about dust.....

my fren's pc..

edit: the case is closed.... but havent clean for years...

The dust depends on the place.If the PC is placed in the room full of dust,there you go.Take it.

Good...coz max air flow can hit your casing...hoho..

Plus it will be more better for those who uses air-conditioner inside their room.

Not good man. Noisy + collecting dust

like tat better not use casing bro

am i rite or not

just to share my experience.
few years ago I use an open casing pc.
then on the weekend went to the beach then after coming back, about 7pm, there's a snake hanging on the wall. we tried to jolok it, then it fell on the computer table. straight away it went into the pc.

I was like..whaaa!!! dont!!! xD
luckily no volt shock happened. He sat at the 5.25" Bay.

Thank god it doesn't grab on you when you jolok it...... Thanks to your open PC to provide protection to the snake..

then how u get rid of d snake anyway...

my guess will be, he close the casing, throw it all together. safer that way

trow, hahahahha

he threw away the whole set, im guessing he use shieldtox + lighter burn it . .. no laaa.. impossible.! im guessing he just left it there as his pet .btw. im using open-casing now , No problem whatsoever. my temeperature is cooler by a few degrees if i open it , .

Is it appropriate to drill alot of holes on your casing?
I mean A LOT...

It will not costs a problem.
But what for drilling a lot of holes?

I got a cap ayam brand, the design is like cap unta brand. I didnt open the casing because can easily collect dust and also noisy. Bad for ears.

Why is it noisy?? i think you uses a lots of fans,chipset cooler with fans,gpu cooler with fans.

open or closed?
my CM C5 is always closed, there's once , i found a dead grasshopper* inside .....
my intake front has a filter my back is exhaust.....


*my house has no grass areas

it depend on ur fans la..
buy silent fans will help the sound more silent

the article is not wrong.

but btw, we don't have radioactive elements in our PC.

not necessarily. even cheap mATX casing and OC GC, with proper placement of fan you can have good ventilation. it's not about casing size or quality. it's the science of cooling.



open casing DOES NOT give better airflow. you have to put a table fan to get the max out of it.

if you use stuff like Artic Cooling Accelero S1, you wouldn't want to use open casing unless you run the Turbo Module. same goes to running fanless.

FYI my system ran fanless. once i open casing, the system will hang sooner or later. this already proves open casing DOES NOT mean better air flow.

*if anyone wants to argue with me. i run a silent PC that runs fanless on the processor and relies heavily on casing air-flow. it was done by spending hours observing fan speed + temperature to have an optimal setup that works with low-noise and acceptable temperature.



if article for newbie. how can you not trust it? again it depends on the article. i find forummers and people who lack knowledge are more damaging that newspaper articles.



i did both. side-panel open doesn't bring better air-flow or make it more cooling.

if you open side-panel and the temperature is better, then it's clear that your casing doesn't have good air-flow in the first place but that doesn't mean open side-panel always bring you better air-flow.

------------

so yeah. that's about it.

oh and about dust. when your casing have good air-flow, it's not surprising to have dust collection. as long as there's moving air, there will be dust collection. even if you put dust filter (which hurst the air flow) there will still be dust collection some where, with filter on means it'll be on the filter la so either way you still have some thing to clean.

Sorry, by stating open casing gives better airflow is actually wrong, my bad . I was meant by open casing gives more air, more fresh air to the hardware thus making it cooler.

Err, abang goldfries, is that wrong or correct ? Please correct me again if Im wrong

Added on January 26, 2008, 1:50 amQuestion ! This is relying on ambient temperature ? U state that u didnt use any fan in ur pc right, so you were actually observing which fan speed ?

And second question, this is completely relying on fanless rig, how about open casing with fans rig ? Would the result be same ?

Edited : After reading few times I realized u were saying was your processor doesnt have any fan, while how about case fan ?



This post has been edited by mizivincible: Jan 26 2008, 01:55 AM

ok. see, if you're in a hot room and no other flow of air pointing to the casing. then the air-flow isn't that great.

on the other hand if your casing itself has little to no air-flow, then of course opening side panel would result in better ventilation but that doesn't mean it will always be better.

open casing works best when you have table fan blowing, or at least have moving air around.

btw my 2nd unit is now open cased........ haha. well that's because i forgot to close and didn't bother to close.





yes. your cooling always relies on ambient temp.

your casing should have the ambient air going into the casing. cool the components then pushed out via exhaust.

my system relied on 3x 120mm fan. you can see ianho's services, my casing side panel is there. my CM C2 ventilation sucked. i spend quite a bit to modify it to the way it wan. good airflow + low noise.

yes. i observe fan speed. not exactly monitoring the RPM la but i monitor adjust the speed and observe noise level + temperature. to me RPM is not important, more important is the air-pushed vs noise vs temperature. to strike a balance.

my current setup using fan la. the one not using fan was my X2 3600+ on OC 2.5ghz running scythe ninja fanless. side panel off - sooner or later will hang. side panel on, no problem at all.

on my case, it was specially made for air-flow cos i want a silent setup.

even my current rig is silent setup, all fans are controlled by Vantec Nexus.

wow..open side panel will hang, n didnt open will not...hmm.. quite interesting..which mean even u open the side panel, doesnt mean tat definetly u will get better air flow huh..

good with a table fan direct blowing on it

Open case here.. cos am too lazy to put case back on.

for open casing,u'r mother board will eat dust
better not to open it's casing

not only mobo lar
all the hardware will covered wif dust lar

guess most of the ppl here lazy 2 put it back after remove/add somethngy? or its easier 2 remove/add if its open all d time..? i'm 1 of them..

these ppl donno how to appreciate their precious

hahaha.. i hav to agree somehow that removing a case is not a good idea.. first of all ur rig will be vulnerable to 'outside' intrusion and second.. walla wei.. on the 'look' department, its just damn not nice laa.. yes, technically the fanned one will get more air but can get the damn cicak and lipas oso.. then u see it is 'cool' or not.. dont trust me arr? see my rig lor..

i'm not sure this fall for the cable management thread or extreme case mod thread.. neway.. enjoy loughing..

actually i just remove it from my previous case. its a custom modded case. the 2nd one actually. (yes i do modding) poor thing at that time i never kno malaysia got mod site.. but its not cool anyway so what the heck.. i'm stripping it down bare naked for my next mod.. thinking of a cube case much like the apple GCube n thinking of attaching a 6" LCD straight to the case aside of the AGP out for monitor.. but oni in dream lor.. I will post here when i start the project (hopefully)

Grass Hopper... wow

mostly it depends on your fan's RPM, if you think your fan is running on a very high speed and producing lots of noise,
just change your fan's positive voltage from +12V(yellow) to +5V(red)
in other hand, this means under powering your fan la
it only works with 4-pin Peripheral power connectors (connects your HDD and CD-ROM) and 4-pin mini connectors (connects your FDDrive)

Click here for more info

nice system, btw my new system also going to be like this...
as for my E8200, i will use a super long heat sink(used in Core 2 Quad) but fanless...
My GPU i might get a Gigabyte 8600GT with passive heatsink.
and add a 120mm "cheap" fan at my side panel and underpower it. (haven't determine left or right yet, need to mod)
silent... and cool....
hehehe

yaya, agreed...

the 'not cool' part refer to my case mod. not this mod site.. hope nobody got offended by this mistake..

Thanks bro. Understood. Another question please, my setup in college, I place my system beside the balcony entrance, which means the wind and air from outside is blowing towards my system, I thought by closing my panel, the wind or air couldnt penetrate my sytem, how do you look at this matter ?

waaaaa, berapa puluh tahun tidak bersihkan itu 'casing'?
like a construction site, full of dust
sorry if im so rude
just my comment though

ps: better be aware that dust 'might' cause electro static (correct me if im wrong )

Definitely a bad idea. Dust + non-contained airflow means inefficient cooling and dust bunny BIG TIME. In fact, I'd recommend a casing with a minimum of 1 intake and 2 exhaust, 120mm at least. I read that it's recommended so in order to have stronger vacuum of air outwards instead of instead, getting rid of more heated air in the process....

I voted True.

Because My Desktops are workstations, they actually use the big intake hole in front to really push the air to the back.

HP Workstation XW4100 & XW8000

If you open the case, the temperature gets really hot.

However, If you have the case closed, the air from the front is really strong XD

but still, If talking about dust, these 2 workstations don't make any difference with open/close case because the dust really gets thicken and there's spider web O_O

my friends pc oredy got semut bermastautin kat situ...
so better close ur casing lor...
and make sure ur casing has a good airflow n no need to open d side panel..

yup. cos you see, i was running fanless even for the processor.

if not air-movement then the heat doesn't leave the heatsink and all goes down.

casing close, i could do folding on both cores at 100% and still survive warm day.

it's a science of moving air. hot air goes up. when hot air goes up. there's vacuum, thus pressure leads to cooler air moving in to take the place.

in my case, cool air come in from the side. warm air goes out via PSU and exhaust.

when side panel taken away

1. no more cool air, even though the panel is open that doesn't mean cool air goes in.
2. warm air not properly pushed out, since pressure created by the panel is not there already so the exhausts will only pull top layer air while those at the mid / bottom move far slower.

Added on January 31, 2008, 1:58 amso can you guarantee the air will enter the casing? and whether the air will be cooler?

for me, my system placed on the floor. logic? air is coolest at the bottom.

anyway for better AIR entrance to the casing, use a fan or 2. most casings have front panel that allows you a 120mm / 80mm fan. put one that, it also helps cooling the hard disk.

By the way,not using a case is always good.

Yeah. You rite. The regret later after someone accidentally splitting water at your naked PC. lolz

Owh,i've been thru that.I accidentally split warm water into my PSU.
The psu,hdd,dvd and mobo kong.
But its ok,i will never regret using naked rig.

if got children at home better close the cassing...for me I've never open the casing even the climate is warm. If I think its warm I close the computer for a while then do back what am I doing before. Take more Hazard and Safety prequation in life...anyway its only a machine.. if die always can get new one or let it be like that and enjoy other activities.

wah, where u put ur pc? split water lo..sure all kong..

Its naked and placed left lower down the table.
While playing games,i accidentally knocked the cup containing plain water using the mouse.
Yup,all hardware gone.But now new rig.

it's useless for changing new rig just because that accident....
do u still put ur new rig outside without casing?
i prefer not to open ue casing if u love ur rig hehe

n if u love ur wallet.. new rig is gonna cost u money leh..

"split" ?..............................

Nah,all the hadwares gone.Its useless.No point for me to keep it.
Right now i am still using a naked RIG.

No lah,i built an old pc only.

I mean "tumpah".....................

IMHO, open casing with nicely maintained is better than others (provided in air conditioned environment) but without casing is fragile as the components exposed to danger (water, humidity other)...

After i closed my sidepanels, my HDD temperature drop by 2-3 degrees

same goes to me,hdd temp drop around 3 degrees but gpu n cpu temp rise around 2 degrees...

btw,is it neccesssary for the exhaust fan having higher CFM compared to intake fan?

i open my drive bay cover..

I like my computer naked

do like mine..half open half close

i wonder how u manage 2 get such a status?

Invisible case FTW.

d*mn, u r a overclocker or somethngy? anyway.. is tat 8800?

No scare of dusts?

well, in his case.. i thnk got dust he can easily clean it? no blind spot, hard 2 reach places/corners..

your liberty is modular..but seems like to much cacing

i wonder wat tat means...
