How should I have the air flow set up in my case?

Definitely put one in the lower front as an intake.

And your CPU/heatsink fan should probably be blowing down towards the CPU/heatsink, not away.

As for that side fan, try it one way and then the other to see what it does to your temps. I run mine as an intake and it drops all my temps a decent bit but if I run it as an exhaust all my temps go back up. It can vary a good bit from system to system.
 
Hmmm...How am I supposed to change the CPU fan to blow into my CPU instead of away. It is the stock HSF unit, if that matters.
 
Unscrew or unsnap it, flip it, done.

You may not need any extra fans. Run it without and see what your temps are. Extra fans - especially 80mm ones - add a lot of noise for the amount of airflow you will get out of them.
 
A front intake 120mm.
A side intake 120mm. Add on.
A top exhaust 120mm. Add on.
A rear exhaust 120mm.
I would get a LL PC-7B +2 with two 120mm fans already.
Then I would add two more 120mm fans. My rigs use the generic HSFs and still maintain low temps.
If you want the best designed case for cooling your system, this comes with my highest recommendation. You find that your rig will work in the mid-30Cs.
You can get Yate Loons Verry quiet and cheap.....

I've never heard of a CPU fan that blows AWAY from the CPU! Something is wrong there....unless I'm behind the times on that. Still, it doesn't make sense, it "defies cooling logic".

It depends on what all you're putting in the case. Hotter running components are of course going to require more air flow. Don't be mislead like others in getting high CFM fans. For spot cooling (like chipsets) you want smallish high RPM fans due to their greater static pressure, which is what does the cooling. Ideally for that is the fan would be no larger than the HS or chip. Now for CASE cooling, that's where you want the high CFM fans, and again ideally you want the same CFM coming in as going out.

Regarding your specific diagram; you'd want the 80mm fans blowing IN and the 120mm blowing out, and don't forget the PSU's outgoing fan to add to the total outgoing CFM. Also don't forget to take into consideration those ridiculous restrictive grills on some cases. I've seen them reduce CFM by MORE than 50%! And if the intake areas have different grills than outgoing areas, you have to try and figure that into the formula. I always use a nibbler or roto spiral cut tool and cut out the grills on my cases (unless the manufacturer had a brain and used a large open-weave pattern that is not restrictive). Then I'll cover the fans with those typical wire fan grills that don't restrict anything.
 
First of all, I'm an idiot. Putting my hand near the CPU makes me believe the fan on it is infact blowing down into the CPU. Also, I'm not sure, but it feels like the video card fan is blowing into the video card? Finally, which way is the PSU fan blowing, since I can't really tell?

Now, pkme2, I have no desire to get a new case, but just some fans if necessary, and I have been having some heat problems recently.
 
The video card fan should be blowing down onto the heatsink just like the one on the CPU. If you put your hand over either of them and don't feel a nice bit of air blowing on it then they should be blowing the right direction.

I don't know what PSU you have but its fan should be blowing out the back of the case and if it has a fan on the bottom it should be sucking air into the PSU. If your PSU fan is blowing out the back of the case you should be able to put your hand there and feel some warm air. If not, then either the fan is the wrong way or it's a pretty weak fan.

You don't necessarily need a new case as long as you're not a freak about a bit of noise coming from your PC as 80mm fans are louder than larger fans. Get an 80mm fan with a decent CFM rating and put it in as a lower intake, get another 80mm fan with a decent CFM rating to put on the side (you'll have to experiment to see if intake or exhaust works best here) and you might as well replace your 120mm fan with a higher CFM rated model to even out the new 80mm fans you're putting in.

Then, try switching out some of your fans for 120mm. These Yate Loon 120mm are my recommendations. Veerrry quiet and cheap.

You don't even know that he can fit more 120mm fans in his case without doing some modifications that he may not be up to doing. Not everyone is worried about a bit of noise from their PC case.

What so difficult in putting in some 120mm fans? I PMed him with some ideas that I used to add 120mm to my PC-60s. Since he asked, I complied.

Some PC cases won't let you put a 120mm fan in the 80mm fan spot without some modding...my CM Centurion 5 for example. The OP didn't share what specific PC case he has and it seemed like you just assumed it was as easy as just popping in a 120mm fan.

My LL PC-60s came with 80mm top exhausts and I popped them out and installed 120mm using my Rotozip w/ 120mm templates found online. I also cut out side 120mm intakes and if he needed a 120mm cutout hole saw, I told Josh, that he can get it on eBay for $17.

He can still use 80mm for areas which are more feasible than 120mm. That's his choice.
The YLs are still the best 120mm deal available for $3.45 online that's quiet and can move 47cfm.
 
Well see, that was the confusion...you PMed him info that wasn't posted in this thread. If I known what you had told him then I wouldn't have said a word.

FWIW, that's awfully weak. The 120mm fans I use in cases are about 95-120cfm (depending of course on model and application, most are YStech). If you only have a 47cfm fan blowing out the rear, and going on the assumption your 80mm PS exhaust is a typical 25cfm, that's only about 72cfm total outgoing. Now while that could be easily matched with your 80mm intake fans being about 37-40cfm each, that's not going to be enough cooling for most fast PC's. (I have about 225cfm in and out on my case! Hee hee.) [insert wind tunnel icon here]. LOL. :laugh:

Since you only have one front fan, it would be best to make it and the side fan at LEAST a 50cfm (Sunon makes these) or better yet if noise is not an issue, the Vantec Tornado (about 83cfm) and match the rear 120mm fan's CFM accordingly. 83cfm (front) + 50cfm (side) = 133cfm intake; and a ~110cfm 120mm rear fan added with the PSU's exhaust would be about 135cfm, perfect. Note that a little "overpressure" is usually desirable since any overpressure would go out the holes around a mobo's cards' slots cooling any cards a little bit.

Again this is assuming the fan grills are not of any issue as I mentioned in a previous post.

Yes, if you're cooling a P4, I can see why the need for 225. Since Josh isn't in the market for a case like yours as he mentioned in his previous thread, I suggested the 120mm because it works well in AMD rigs and are super quiet.
 
This may be a radical idea, and it might not work, but this is what I would try:
1. Duct the side vent straight to the CPU HS/F
2. Add a 80mm fan to the front bottom. If you can fit a 120mm-->80mm adapter in this spot, that would work better.
3. Remove the PCI slot cover just below the vid card

This set up would insure that the CPU would receive 100% fresh air and its fan would help cool the PWMs and memory. The warm air would then be exhausted through the PSU.
The front intake would help cool the chipset and the GPU. Since this would be a positive pressure system, the open PCI slot cover would allow this air to exhaust after the vid card.

The only problems I see with this type of setup is that the memory might not be cooled very well, and the front intake may be too low to deliver fresh air to the chipset. However, I think that both of these problems are more of an issue with the case itself.

Just my two cents worth.

I know, I was just pointing out the hilarity of mine. 😉 Heck, that's overkill for me! I thought it better than to over-cool than under do it! 😉 It's hilarious to see temps inside the case LESS THAN ROOM TEMP! LOL! It sounded like a friggin' jet engine! I replaced one of the front fans (that massive Vantec Tornado 80 x 38mm 83cfm) with a 50cfm, and replaced the CPU fan (monster Delta 60x38mm 8300rpm 50+cfm) with a 60mm YStech 40cfm. Temps are still really cool. Now it "only" sounds like a small turbine. LOL.
 
Does your case have the TAC 1.1 complaint VGA vent just below the video cards?

If so, I'd say don't put a fan in the 80MM hole in the side panel. That's supposed to be just a vent. And definitely put an intake fan in the lower front.
