Silly cooling question or is it?

[GunRunner]

My system is as folllows:

Antec 900 case with stock fans
EVGA 780i motherboard
2 x 1GB GeIL Pc6400C4 (GX22GB6400UDC)
2 x BFG 8800GT OC2 (512MB) SLi (I play IL2 Forgotten Battles)
E8400 Fitted today (In the process of overclock testing) (Did have a E6600)
Arctic Freezer 7 Pro set in the BIOS to Run at 100%
Benq 24" monitor running at 1920 x 1200 (Hence the SLI for Forgotten Battles game).


I have a noctua NF-S12 Fan (120 x 120 x 25mm), and was going to fit it in the side panel that has space for it to blow air over the top of the RAM and the 2 video cards(using one of the motherboard 3 pin connectors), and then it was suggested by a friend that maybe it would be better to have it suck air out of the case and turn the up the settings on the 2 front fans that push air over the hard drives, and also increase the fan speed of the top 200 fan to extract even more air.

Has anyone any comments? There are many ways to cool the internals! Is there such a thing as the correct way? At present I am testing the CPU at 3.8ghz and the temperatures with prime running are 60 C on both cores using vcore auto settings that corresponds to 1.3 volts.

Note. When I am running the game (IL2 Forgotten Battles), the GPU's run at 81 and 84 degrees centrigrade, that was why I was thinking of pushing more air over the Graphics cards.

Any input appreciated.

Kind regards

Peter

Hiya,
My rule of thumb for case cooling with fans has always been have more air going in than you're trying to suck out, As it finds ways to get out of the case somewhere lol

You'd be surprised how much flow is lost due to air coming through burner/floppy/side panel joins/mobo rear socket panel etc not to mention the slowdown around parts if ribbons/cable etc are not tidied

I think most if not all PSU manufacturers have realised to make their psu's suck air from case through psu and out, If many years ago my psu sucked air in then this warmed air went into my case i would carefully turn fan or fans around

I watercool my cpu now and soon both chipsets and mossfet area, I have a big lian-li she stands 23 and 1/4 inch tall, I have 3x120 sucking room air in 2x120 out and inside assorted fans aimed at ram NB vid mossfet area, Also the corsair psu draws air out and vents to rear via a nice duct that came with lian-li case, Also got the supllied cpu duct now blowing on gpu/ram area also

Really it's trial and error as such

My left panel on the case has the fan at default sucking air from case to room, I turned it to blow air into case and at the moment i can't say as i've noticed any temp drop (maybe lian-li knew something hence it was sucking air out from case even though its a low point in the case

Try 1 more fan forcing air into case than what you have drawing outwards

Also after using the ducting supplied with my case my bro made cardboard (he used to watch blue peter lol) ducts and though it looks crude it does the job

Looking around now what you find in diy stores etc a nice plastic system could be made pretty neatly too

Just try to make sure circulated air is going on the main chips (cpu/gpu/NB ram and drives too as these can warm up well lol

If you watch closely, that side panel sucks air already with the stock fans all running at same speed. You have 2x120 blowing in and 1x120 and 1x rotor blade sucking out.
So yes, blowing in would be the way to go.
