Just a quick question on the flow of air. This is how i presume things should work.

1st off i dont have a case fan at the bottom but will be replacing the one near the CPU sometime soon, and will get a copy for the front.

I also want something like a Scythe Infinity, would that be the right way to point it from that diagram?

The NB is passive on my mobo, cheers!

That's roughly right for most system's airflow. some have side pannel fans and roof fans, but its nomaly a similar design (short of the more exotic Lian Li cases)

Other than that, Scythe Infinity would be a decent choice, Tuniq Tower 120 and Ultra 120 Extremes are good alternatives.

which case are you getting dokko ??

Ive got an Antec Sonata II (IIRC)

Its big, and is quite cool with one poor case fan supplied.

I was thinking of replacing that and getting one for the bottom, probably asaka ambers 120mm, an infinitiy (although i'm worried about the weight as the P35C DS3R doesn't come with a back retention bracket, and an OCZ 600W PSU is on its way.

Also the GFX is an 7800GT, which by xmas will be an 8800GT.

Tell me about it, was at college and it blocked me after posting and i couldn't amend it in anyway.

Just got in, got the image somewhere.

Excellent mate, i thought thats how it might go, but i wasn't sure.

Its not going to be used for extreme OC, probably moving my E6600 on stock volts to 3.2 (which the previous owner did fine) both cores run at about 40c under load at stock, which is brilliant.
 
In general the rules for case airflow are:

- Intake through the front (pref the bottom) and sides
- Exaust through the rear (pref the top) and the top of the case

Try and have greater intake than exaust this causes high pressure in the case and more dense air that is better for cooling.

Also in the case try and keep airflows "in-line" ie. heat sink on CPU blows straight out on to rear exaust, you want the air to being recycled through the case as quickly as possible, this will enable maximum heat to be removed and also will prevent air getting stuck or just swirling around inside

'Cool' tips mate ;)

:D

So should i get a lower powered fan for the back, or just take it down a notch or two in terms of RPM?
 
well I would say depends on what cooling you have and how many fans! In general I would say if you have 1 intake/exaust best just to leave them, if you have multiple intake/exaust then have a play about and see what works best..

On my current setup I have:

Intake - 1 Fan Into Bottom (120mm), 1 Side Fan (80mm), 1 Intake Ducted Straight to Heatsink (120mm)
Exaust - 1 Roof Exaust (120mm) 1 Rear Exaust (120mm) + PSU blows Out

So I no given the relative CFM of the fans that I have more intake than exaust

As to type and speed of fans again is very much personal preference I would say go for more powerful fans you can always run them slower for less noise and you have some power there when you need it.. I run all Delta EFB1212SHE which offer nice performance when needed and can be run off fan controllers / motherboard to give some control to there speed... so they tend to idle along at 30% and nice and quiet but if I need serious cooling my case can take off :)

Good idea that, although i wont be doing any serious overclocking it would be nice to know theres enough under the lid if i ever wanted to take things further.
 
I normally have my Q6600 idling along at 3.4 (425*8) or 2.55 with speedstep on so for everyday use it runs along nicely at 2.55 and is virtually silent... If I want to mess around with the Overclock (most weekends :D) then I have the cooling there to do it..

Plus for some reason its a lot of fun to power the fans up and down lol... scare the cat off hehe
