not enough intake fans?

Current setup:

 

Intel q9650 @3.5ghz

Dual evga 9500gt

2x2 800mhz ram

xfx 750i sli

WD green 1tb

Freezer pro 7

1x 120mm outtake

1x 80mm outtake

1x 120mm intake

 

The Freezer pro 7 is pushing air out the back along with the other two outtake fans. The intake fan is being blocked by the hard drive rack, and so isn't doing much good. I saw an intake fan (Titan TTC-HDC5 HDD & System Cooler - Retail ) that would go in the cd drive slots I'm not using, right in front of the cpu. If i got this, would it make a significant difference?

i presume the 80 mm outtake or exhaust is on the side, try turning it and making it an intake, that will help your cpu temps, also you probablay have a psu with a 120 mm exhaust too

I have a SIGMA LAVIE case, and I don't think switching the side fan would help, just because it is fairly far to the back of the case. Pic is attached, yellow circled fan is intake, red circled is outtake.post-67700-1245088580_thumb.jpg The PSU exhaust is blowing down on the cpu, so that isn't helping. I have a small 60mm fan i can add, but i dont know where I would put it in

Some wire management would definitely help your airflow ;)

Start with wire management.

Split loom and zip ties for cheap!

Once you have that done, see what your temps are at.

Ok, I fixed up the wires and flipped the case window around so the fan is on the bottom above the graphics cards(gpus got over 60C). I added another fan on top of the 80mm side fan, both outputting (seems to work better that way). I wedged a 60mm in the 3.5 bays, cause I'll never use them anyway. It has improved some, but still gets to about 70c at max under prime95.

What make of power supply is it? All the power supplies I have tested, and pretty much all power supplies at the moment, pull air into the power supply from the case and exhaust it out the rear!

Where is your case located in your room? Does it get cool air where it sits?

 

One thing to remember about case fans is that you need balance. It's okay to have a slightly negative or positive pressure, but you don't won't to throw things too far out of wack. Too many intake fans tends to overwhelm the exhaust and you end up with a case full of circulating hot air, the cool air you bring in becomes warm instantly after entering the case. You can test this by removing your side panel, if your temps go down then you need more exhaust fans, if they stay the same then you are okay and you have a good balance.

Ok, i can check those (the power supply is a corsair 550w). I might also try lowering the voltages a little, they might be a little too high, especially the ram, its not OCd at all.

The power supply shouldn't be blowing warm air into the case!

Never mind about that, I just thought it was before. Checked it, its blowing out.

Lowered voltages, seems to be stable and slightly cooler(2C). Still wondering if theres somewhere I could add another case fan
