Case fans...

[Dethred]

I am getting a new case for Christmas from my girlfriend, and I was wondering if improving the number and locations of the fans will make much of a difference in cooling my system.

Right now I am working with 1 80MM fan on the rear of my case and the PSU Fan.

The Case I am getting has a side panel 80MM, A top mounted 80MM, will be adding a 120MM rear fan, and two 80MM Hard drive fans. Will this dramatically change in case temps? The 80mm rear fan I have now never really blows out warm air and my temps seem pretty good all around.

Also, are there any slot fans that might help out the dinky fan on my XFX Xtreme edition 7800GT? That thing has the crappiest fan I can imagine and was wondering if there was a fan for forcing more air into there.

PS: The XFX stock cooling is better than a Zalman 700cu copper HSF so the stock copper heatsink just needs more air.

Re: Case fans...

I would put a 120mm in the front for intake as well. As for the 7800GT how about the NV Silencer5 (rev 2)?

Re: Case fans...

you need AIR FLOW .

Putting fans on your HD's won't change a bit.

Best thing to do is, place or 1 120mm fan in front of case , or two 80mm fans in front that are blowing AIR IN the case .

Then one 120mm fan or two 80mm fans in the back of the cae blowing AIR OUT of the case .
(note , your PSU will also blow air out the case in the back, this is why you xhould never work the other way around) .

this way you get a very nive AIR FLOW in your case, this AIR FLOW will cool your HD's in the front, and will bring very nice fresh air to all your components and coolers in the PC.


In my case, I have two 80mm fans in the front blowing air in(running on the 5V line, meaning they run half speed) .
1 120mm fan in the back of the case blowing air out, also running half speed.
also the PSU blows air out (120mm fan) .
I have a very good air flow, and this one brings very cool air to my CPU cooler, when my system is idle, the cpu temp is exactly the same as the case temp, meaning the cooling works perfectly (proof of cpu cooler having constantly fresh air) .

Case temp is always stable, about 4 degrees higher then room temperature, stressed or not, the case tems ramaines the same.

Re: Case fans...

if u can arrange it have fans on the bottom as intake and on the near the top of the case and extake.

not as good as intake in front and out on back, this because the HD's are placed in front of the case

That is what I am getting.

Pretty sure I am going to Use the side fan as intake, two 80mm front fans as intake, top fan as exhaust next to PSU exhaust fan, and 120mm exhaust in the back.

Don't wanna spend a lot of money on something that is pretty much the same as my stock cooling but has a larger fan. I just need to figure some way of blowing a lot more air into the fan port of my stock cooling solution. If the Zalman 700Cu HSF raised my temps by 15-20 degrees in respective situations, then I am not trying anything but forcing more air in there.

Re: Case fans...

Make sure you put fans at the bottom of the front for intake. An intake fan in the door is also good, as (depending on mobo/case layout) this blows fresh air to vital components.

Blow the air out the back of your computer, preferrably near the top. This way you do your best to ensure that the "output air" doesn't get sucked into the case again, but disperses out the back upwards.

Personally I've got four 80mm fans in the front, ensuring a good intake and proper cooling of my hard drives. There's also an 80mm fan in the side plexi, blowing fresh air directly on to my CPU, RAM and NB.
On the back I've mounted two 80mms for exhaust, just right below the PSU. The PSU also blows out air with its 120mm and 80mm fans.
My case is normally around 5 degrees celsius higher than the room temp, and I've never had any heat problems with this setup.

Someone mentioned weak cooling on the XFX 7800GT?
I've got two of these myself, and never noticed any heat problem. They're resting at 51 and 56 in idle, and about 60 when playing.
The CPU never gets hotter than 55 with its standard cooling.

Re: Case fans...

You should just go with some more airflow indeed, just buy some casefans, take once under 25dB (otherwise they will become noisy). Casefans only cost about 5 euro or less.

Re: Case fans...

I am pretty much doing what you guys said to begin with so I think I should be good to go. My XFX runs at 35-39*C Idle and only goes above 50*C in 3dMark05, usually at 42-43 in BF2.

Re: Case fans...

i have i 120 on the rear for blowing in the fresh air, 1 80 on the bottom for blowing again + i am gonna buy an nifty little fan which screws into an empty backing plate(at the end of the pci slots which just sucks the air out, ive seen it working and it does the job + ive got a ram cooler sleeve that dissapates the heat away from the ram!
