Getting better airflow in my case.

[xNIKx]

Ok so heres my idea.
Im trying to cool down my pc better. graphics card, cpu, ram, north and south bridge, ect.

First off this is what im buying.

and a 80mm or 90mm fan.

Im going to add the front 120mm fan to try and get some airflow over my ram.
Im going to add the 80/90mm fan at the bottom with long screws to stand it close to the 8800 to feed air to it and the slot cooler to pull the hot air away from the 8800.

These pics arnt that good but bare with me.

Questions

Will this cooling help lower my temps all around such as my chipset, ram, ect?
Will too much air be coming in and not enough coming out?
What fan should i put at the bottem?
Will this make my case really loud?

Pics of my current setup.

What are your temps currently?

If your 8800 is running hot, do you have the fan set to 100% RPM? The way to do it in the Nvidia control panel is kind of iffy, RivaTuner lets to you set it to change at startup.

 

[xNIKx]

my 8800 idels at 52 loads at 60s but at night with the door shot it gets alot hotter ideling at 62 loading at 70s.
fan speed at 80.

 

[LOUISSSSS]

1. you're ram doesn't need cooling
2. 80mm fans are generally useless... stick with 120mm fans. and doing that probably won't drop your gpu temps enough to justify spending more than $1. to lower your GPU 1C...
3. the loudness of it depends on the fan and the RPM it spins at

4. yes, it will create some airflow in your case, and it MIGHT drop your cpu temps a bit, but not enough to justify $20 and all this work u put into reading this thread lol.

 

[WoodButcher]

xNIKx, Ignore the sarcasm, your looking in the right direction. If you use larger diameter fans they will move more air with less noise. My preference is Yate Loon 120mm high speed w/ a fan speed control.

 

[Engraver]

Fans aren't going to do much more then, since your problem is happening from your ambient room temperature increasing. Only things you can really do for that is turn your gpu fan up to 100%, turn your AC up at night, leave your door open to get more airflow, or open a window (if you live in a place that actually gets cooler at night).

 

[xNIKx]

well i was testing it out and i put my top 90mm fan at the bottom and lowered my gpu temps alot, css was only loading at 58C when it usually loads at 65C. but then my cpu temps rose alot so i put it back at the top.

and if i replaced my rear 120mm fan, my front 2 120mm fans with these yate loons would that help?
http://www.frozencpu.com/produ...4UB.html?tl=g36c15s518

then i would use one of my 120mm thermaltake fans and put it at the bottom.

 

[WoodButcher]

I think the one you linked is the low speed, Quiet but less air than this from jabtech. I think someone at frozen CPU goofed in the listing. I have the fan you linked and there is no comparison the high speed which I also have. The D12SL-124B listed at Jabtech, the same model number you linked. The Yates high speed you will want a control with, the low speed are extremely quiet at full speed.

edit- I deal with both companies and they are both great, call before you order and get it right. jabtech is cheaper!

 

[xNIKx]

will the yate loons make much of a difference?

 

[WoodButcher]

Replacing your existing fans with yates won't necessariliy make it cooler, depends on your existing fans, if they are high cfm fans, no it won't get cooler, just more quiet. If you add fans and / or replace existing fans with larger fans, yes this will make it cooler.

 

[WoodButcher]

double post!

 

[xNIKx]

these are my current fans

[WoodButcher]

I've never used that Thermaltake so I can't give an educated answer. The D12SH-124B yate loon is comparable according to the specs listed but I would bet it is quieter and I know it costs less.

Edit- Buy the one or two yates you need to add and let us know how they compare. You can find yates in an 80mm also.

 

[firewolfsm]

8800s are safe with temps in the 80s. Just forget about it, your temps are great. It only matters if it's limiting your overclock, which in this case, it isn't. Getting lower temps just for the hell of it is retarded, noisy, and a waste of money.

 

[xNIKx]

with new games coming out like crysis i know they are going to be making my temps alot higher.

 

[xNIKx]

and what slot cooler is the best choice?

 

[SolMiester]

Hey xNIKx, looks like all those fans compete for airflow, if anything, I would move one of them to the side over the gpu. The PSU looks like it fights with the fan next to it, and not sure about the top fan either.
Can you separate the top chamber from the mobo chamber with a bit of sheet metal perhaps?

Good thinking, those two up top are just making noise. volt mod them to 5v from a molex or use a controller. Separate the chambers w/ cardboard, make something nice if it works. {lexan maybe?}
Then maybe add one large fan, intake in front of the empty drive bays above your hard drive. Is it possible to move your HD cage up to have the second front intake at the bottom w/ unimpeded air directly to the GPU?

 

[xNIKx]

ive have long debate with ppl about the psu and 92mm fan next to it. they are fighting for air but they sayd its not that bad and if i put my hand near the psu i can feal air going in.
and i wouldnt want to seperate the top because those fans really help my temps actually.

" it possible to move your HD cage up to have the second front intake at the bottom w/ unimpeded air directly to the GPU? "
i could do that.

do you guys think i should wait for the new games to come out and then decide if i need to buy these things or buy them now?

 

[SolMiester]

I really cant see any air-flow per sa in that case with the top fans pulling against the exhaust flow at the back. Maybe the fan and PSU help keep the case cooler, however airflow doesnt turn, it takes the quickest easiest route. If the top 2 fans and psu fan are helping, its because they are robbing the rear exhaust, leaving the gpu area air stagnate, if that makes sense. I would try sealing the top from the bottom, just try some tape for now to get the seal and test, then move 1 of your top fans to the gpu area.
Do you have a side window, if so do a test with some smoke (coloured if required) to watch what it does! You might want to do that in the garage though....LOL

Let us know how you go on!

 

[firewolfsm]

Run ATi tool's stresser and see how high your temps go, that higher than it will EVER get in games.

Newer games just mean slower speeds, not higher temps.

ive tryed moving the top 90mm fan to the bottom and my gpu temps went down alot but my cpu temps rose alot.
i think i already posted this test.

and firewolfsm the last time i ran ati tool stress test i ran it for like 45min and hit 87 i think.

 

[SolMiester]

Did you try using tape to separate the chambers?, maybe worth a try just to work out what gives better flow & temps etc etc!

 

[BonzaiDuck]

I'm not going to go bazoobas promoting what I've already posted over the last week or so at great length.

The assembly that comes with the fan may be very useful, and eliminates need to do sheete-metal work with perf-steel and 1/16" mild sheet steel, although you could build it. For that price, I'd rather buy.

But the fan -- as far as I see -- and given my own cooling needs and priorities -- is inadequate. Sure you can get 12 dBA on the noise angle, but 800 rpm and 30+ CFM is pretty darn limp. I'd even think it worthwhile to buy the product for $16 or whatever, then replace the fan with something beefier.
