Seeing that i have time on my hands, i decided to increase the air cooling capability of my Xbox.

My requirements / objectives :
- Increase air flow within the Xbox (increase the air flow into the case)
- Prevent dust buildup (maintain positive pressure and filtering the inlet fans)
- Do not void the warranty (no chassis modification or opening of the console

Part A : Setup theory

In the Xbox, there is two main possible inlet / outlet points, where are : (xbox, lying horizontal with you looking at it in front)
- the right side (not the hdd side)
- the rear

Before deciding on my air cooling setup, lets do some research. We shall use the HardOCP Nyko vs Pelican review as a case study : http://console.hardocp.com/article.html?ar...CxoY29uc29sZQ==
From the review, we can see that :
- Nyko is an outlet type cooler, which sucks air out of the xbox. It is mounted on top of the existing 2 Delta 70mm fans, and has a body which acts like a small shroud. It has 3 fans, running at 12v.
- Pelican is an inlet type cooler, which pushes air into the xbox. It is mounted on the right side (or bottom if the xbox is verticle). It has 1 fan, running at 5v.

Seeing the review results, we find that the Nyko is better than the Pelican by about 2.3C at best. So most people would think that having an inlet at side, and outlet at back type setup would be good. Until i read this : http://www.overclockers.com/tips336/

It seems that fan stacking, doesnt really help much, unless, you stack a stronger fan on top a weaker (which is same as using just the stronger fan alone), or you stack a contra rotating fan on top of another. In that case, why does the Nyko increase the cooling performance of the Xbox?

I figured that it is because the 3 fans on the Nyko, collectively, together with the shroud, sucks more CFM than the 2 stock fans inside the Xbox. This is not really a efficient design, and it would be better if the original 2 fans are just removed, and the Nyko is used alone.

Also, what impressed me is that the Pelican, having only 1 fan, and running at 5V, managed to hold off just a 2.3C difference. If the voltage were to increased to stock 12V, and more fans were added, i believe the cooling performance will be better that of the Nyko. Even better still, if the Nyko can be modded of push air into the case instead, and mounted onto the rear, and the 2 original stock fans removed, that would have been the idea situation.

But of course, we cant open the case in order to preserve the warranty. So the rear fans must be left as it is. Thus, the basic setup of the xbox air cooling has to be inlet at the side, and outlet at the rear with the above reasons as my justification.


Part B : The equipment and setup

The fans that i'll be choosing will be determined by its :
- air volume (CFM)
- fan noise
- static pressure
- dimension

Actually, before i did the research, i actually gotten myself 2x 70mm thin profile fans pushing about 30CFM and mounted them on the rear. The air flow was pretty muffled because of the grill behind, and turbulence caused by the original 2 fans served to further decrease the performance of the 2 new fans. I have now removed the two fans, and decided to remount them on the side, to push air in instead.

The problem im facing now is, whether the current fan i am using has enough static pressure to force air into the case. Because the air flow from the fan will be obstructed by
- filter
- plastic grill
- internal metal grill
I'm also wondering whether does a home made shroud be able to improve performance.

- to be continued with pictures and more updates -

OMG! I can't wait for the next update

I suggest if possible both the fan use together and redo the power supply for the both of the fan.

Try get and external adpter which enable you to adjust the volt and increase the volt for both the fan and use it for the same time.

Ya it's noisy but with nyko and the fan stand together, the air flow is big and fast.

im not actually using nyko, but im using the nyko vs pelican as an example to show the ineffectiveness of just using outlet
my project is to, if possible, put both inlet and maybe a stronger outlet over the original xbox 360 fans
my plan is to put more inlet, and slightly less outlet, so that there is abit of positive pressure
it'll prevent dust from entering the vents

im also considering fabricating a duct, but i'll try testing to see whether duct or no duct will be any difference

Heres how i maintain my Xbox.

1. Put it near the air-cond

Good idea, if :

- you dont move your xbox much
- you can afford to on the air con all the time

I cant . I travel between two houses often, and one of the house dont have air cond. Besides that i dont have moolah to on the air con all the time whenever i play .

Is hard to prevent dust here in Malaysia, you know lar the weather

I was trying whether you can test out my idea for me.

I think using both will be better but draw the power source from external adapter.

haha thats why u gotta use positive pressure to keep the dust out. as well as filter the inlet, but u can never get rid of it 100% la

i am using external power source, but i was hoping i can make my own shroud, tho it wont be easy. basically the idea is just like what u meant. two fans for inlet, just like the pelican, and two fans for outlet, like the nyko
but for the outlet, u have to have stronger fans than the stock delta one
and for positive pressure, u have to have stronger fans for the inlet than the outlet

that translates to alot of noise
unless, you use a shroud, and a big 120mm fan, but its ugly, and cumbersome >.<

You need more volt on the nyko fan since you want to avoid modding the stock fan in order the air to flow out.

The best is still putting some carboard in the xbox to lead the air flow way. But anyway, hope you suceeed in what you are doing. wating for your pictureto be up.

yeah best is actually to evenly distribute the air flow from the GPU and the CPU
but i cant open it without voiding the warranty >.<

will try to get pics soon
now is just the 2x inlet only

nope nyko fan is bad...it destroys the xbox360 gpu/cpu
you can google at nyko

bro
did u search b4 create new topic??

Care to explain how it destroy? fan attack?

I know its destroys xbox 360s by starving the unit of power. But im referencing the nyko for the purpose of studying its air cooling capabilities and its design.

Search what?

u have shop is it ? where ?

@mmxzero

FOR CHRIST SAKE CAN YOU GOOGLE??
DO I HAVE TO SPOON FED YOU?
EVEN DAIJOUIBU SAID SO
omg
sry but I have to on my caps for blur ppl like mmxzero

seriously is like you talk so much nonsense
and wihout knowing a thing
and later on u misunderstood ppl(like the simillar thread that I made)
I didn't say fan attack...and pls
GOOGLE BEFORE POSTING STUPID QUESTIONS

@daijoubu

try the xcm fan cooling solution
it can set the temperature of gpu/cpu
means you can control the speed of the fan.
sounds cool eh?
i used in..i got the pictures if you want.
we can share our experience and finding solution to avoid 3rod.
YES AND I BELIEVE WE CAN!
btw I ain't a producer of any products or wtv crap..
I am still schooling!
just helping out
2cents

I'm talking nonesense? LOL

You don't even know how to whole process work. So by using that it will destroy the whole CPU and GPU?

Please research before you start talking bullshit.

By using that fan, it only make your power which is supply to your motherboard is lower and which affect everything not only CPU and GPU. 3rod only happens when is under suppy of power

The only bad thing about that fan is over a long period of time, the plastic will melt into the slot.

i didn't misunderstood your last thread. The last thread you are trying to being a smart a$$ and now you trying to show off infront of me what damage can nyko cooler do.

TS know what he is doing and know the effect of using the external fan. Thats why I suggested using external adapter for the power source.

Please read before you start talking crap again.

and TS, sorry to make this post. But I can't stand ppl who can't do a proper research before start talking crap to someone.

the xcm voids warranty cause it requies me to open the xbox
in fact, if i can cut my own hole, i'll put an even better fan than the xcm

but i dont want to void my warranty
cause putting the fan wont be a permanent solution, it wont fix the problem
i rather send back to singapore and change the xbox. who knows by end of this year, Opus board will be out and i'll get to change for it 0.o then i wont have any 3ROd anymore =D
that is, if the Opus can actually fix the problem

hmmm but ermmm there's 1 video is damn funny
you should check out on youtube
this guy has be calling for the 5th time and also the 5th replacement on warranty.
he is very patient..
lol is damn funny..
btw why do you want to send it back to microsoft..
you have to wait like 3 months?
and you will get 3rod again..hahaha

congratulations!
and pls don't copy what I said
and don't have to say bullshit right after you know the informations given d..
don't follow what I say pls..
you found the answer..good for you..i think you should talk crap and talk bullshit to your own type of ppl.
sorry I don't talk to ppl who still getting brain sicko.
cheers

It only takes a week to replace. Who says is 3 months ?

I didn't google it you moron. I learn that long time ago before you or ME even own a Xbox 360.

Try to respect ppl those who have more knowledge and elderly then you.
