first case mod...
 

I dont wanna make so much tutti frutti milkshake style fun cases so I made this mod. I think it has a industial style finish. There are no heat pumping video card or dvd-roms but system is OCed; I use Athlon XP 1800@2.0 Ghz 333Mhz fsb. Upper fan is spare and nor workind right now(not needed) and other fans are at slow mode..(5V) its almost noiseless. Im planing to paint inside pae yellow and use a yellow cold cathode...

general view:)

Attantion viewers :) PSU brand is Skyhawk and its 300 W. I changed 3 sides with that holed aluminium and its breathing much more better...

front blow-in detail... I dont like that ugly faced cases with blow in hles at front so I took air from floor

upper blow-out

more breathing holes for PSU :)

I really struggle to have that cracked paint effect. But its really cool isnt it:)

that cracked paint effect is unique!

How did you make that cracked paint effect?

by accident? ;)

you can buy something that is called "crackle paint"... basically you put down a base coat (several) of whatever color you want (which will show thru the cracks) and then put a coat (or several) of the crackle paint over the base coat... the crackle paint will "crack" and show the base coat color..

Actually I didnt use one of those crankle paints.. First I apply a ultra thin layer of paint and rapidly apply a very thick coat on it(with same paint). Thick layer kind of shrinks on thin layer I guess. By the way the temp was low when I was painting. I used sellousic paint (we call it like that in Turkey,its odour is very distinctive and hazardous, I think it can be called organic based kind of something in your country. Its not water based,neither syntetic based paint. Usually cars painted with them)

very nice :super: :drool:

I think you are cooling your psu worse than before.
if you look at a normal psu (1 fan in back)
there are only small holes in the back and/or bottom of the PSU
few small holes means little waves of air , but very fast

now you have a lot of holes , and the fan can only push its max of air

what we have here is al lot of slow air moving thrue the entire psu instead of a faster flow through the components that really benefit from the cooling

picture:

Did those parts killed because of bad PSU cooling??? Anyway,very intresting theory. I can't say that I'm convinced but actually thinking on things you say... I think it wont matter too much as I dont use lots of power from PSU. I really want to hear more opinions about this psu cooling thing, if you folks can write I'll glad :)

if you mean these things :
"kills : 2 mobos , 1 stick ram , a lot of hd's , 2 bugs , 1 ant"

no they didn't die because of bad psu cooling :)

i'm gonna do some research about this , will reply if i can prove that what i say is correct

edit : i would also suggest to lower that hard disk ,would result in beter hd temp.

I agree with Bonbon.

with such a PSU housing, the fan in the PSU sucks a lot of air that does not cool the PSU. it will draw most air from the half the side and bottom of the PSU

the big heatsinks at the other side of the PSU will be cooled very poorly

actually i have tried this before, but instead of that holed aluminium , i removed the top of the psu (= bottom if installed) , the fan was temp controlled , and i noticed the pc produced more noise that before.
(it measured more heat , spinned faster , -> more noise)

I installed it back like before and the psu was silent as before.

edit: is your videcard onboard , or just not installed when you took that picture?

so you don't think that the extra layer between you and the FAN had anything to do with the noise?...

if u have a dual fan psu, you wil have a fan that will suck that hot air into the psu
that would be even worse then
i don't think that sophron's solution is a bad one

first a picture of a dual fan psu :

@ jakkerd ;

a dual fan psu blows with 1 fan direct at the hot components of the psu
(i'm short in time , will expand my reply after school)

IMO that's even more wrong. check my attached file

you're saying dual fan PSU's are not good. if they would be, why are they manufactured then? dual fan PSU's not only have direct cooling over their heatsinks, they also help sucking the hot air away from the CPU.

now you can think: oh, the dual fan PSU sucks air away from the CPU so it does get hotter anyway. that's wrong, check the picture. if he would have used a PSU with cover and only one fan, the heat of the CPU would get into the PSU anyway

check the third pic: I don't think the 2nd fan of the PSU may be stronger then the 1st (outtake) fan though, that would make the hot air being blown out at the back of the PSU, back into the case (yellow arrow)

Just do as I did. Place a 120mm in the bottom of the PSU and take the 80mm out.

/me hands Vulk a coffee to get him fully awake!

If you mean by 'FAN' ; the cpu fan ,
then no , the system i tested is very silent. :only 2 fans , 1 low profile 60 mm on the cpu @ 6 V ,(vitual unhearable) and the psu output.

When i took the bottom of that psu out , i installed the pc back , it made no more noise then before, but then the temperature was building up , and i could really hear the psu outputfan accelerating.

The methode Sophron uses results in better casecooling but also in worse cooling of the psu components in my humble opinion.

I tried placing HD lower but there are no slots for that. The empty tray under the FDD is tight and dont let any space for cooling. 3rd 3.5 tray(2nd tray under the fdd) is interfiering with ide ports on mobo. I'm working on a HD holder in front of front blow-in fan. This will make HD realy cool:) My vid-card is on board GF4 MX,its a nForce2 mobo. O/B vid-card is doing well:) I can play NFS underground or call of duty at 800x600 smooth. But I'm planning to buy a 9600 soon:)

Bonbon's fan speed test is intresting. Maybe taking the cover isn't the best idea but there is no way to test this accurately I guess. I put my hand back of the psu and I dont feel hotter air with this new design. Notice that I use 9.2 cm cpu fan,its not attached directly to the heatsink. It blows air not only to the cpu but also on the mobo,north bridge and with the help of holed aluminium to the psu. So as you can see from the picture, heatsinks of the psu are also cooled by(at least I believe so) cpu fan. Thus I can say that if I'd used a traditional cpu cooling then psu heatsinks wouldnt have cooled. This theory explains bonbon's hi-rpm fan noise...

With this new cooling tactics I almost cut the noise :)
1- I dont use noth bridge active cooler,just bought a zalman N/B heatsink.
2- I dont use up and back blow out fans,just the psu fan is taking all the air out. (16-20 C room temp. when summer comes I can active other fans:)

sorry for the pic,I did cut it worngly :)

fixed :)

i guess your 92 mm zalman fan cools your psu also idd , didnt thought of that

anyway your system is stable and silent , so i guess its fine

no, I meant the PSU fan.

anyway , i was correct :p

I don't drink coffee.

I prefer something good for your health.

hmmm, i would always keep an eye on that NB, with onboard video the IGP is going to be putting out more heat than the SPP, so you might be getting dangerous come summer with only the extras from the zalman fan pulling off the heat

I also thought that and asked to the mobo service,they said OK :)

im building a suitcase pc, which means minimum space, forcing me to get the psu to do its most

in doing so, i created my own dual fan psu byt modding ina coolermaster adjustable fan into the housing

even without the back fan blowing, having the fna mounted on the bottom sends most of the air out of the back and little out the side with the cables even though there is no exhaust directing the flow of the bottom fan, i think its just moving on the path of least resistance, and in the process generating a vacuum on the other side drawing in air through the cord side and out the back
