Do I have the best fan layout for my case?

I'm wanting to make sure I have the best fan layout for my case to get the best airflow. I've mocked up a crude layout in ms paint, I'm hoping you can all give me some opinions. Thanks

What are you going to be putting in it? overclocking?

Spec is in sig, pic is stolen from somewhere else, here's a pic of my actual PC:

Side fan may create vortexes over the graphics card due to those fans. I would try it with and without the side fan on, and installed.

SeraphX · 6 Nov 2011 at 23:21

yes, apart from have the side fan exhausting too, it'll help get the hot gfx card air out faster

andy_mk3 · 7 Nov 2011 at 00:21

Okay thanks guys

played about with the side fan and it made minimal difference whether it was suck, blow or off, so I've got rid of it.

When I turned my fans for my H70 around (so bringing colder air from the back) it lowered my temps 5 degrees.

I have a Corsair 650D case, intake at front, intake at back and top fan pushing air from the case out. Because heat rises this seems to me to be the best way to do it, I'm getting 35 degrees idle on my i5 2500K @ 4.4ghz.

I'd reverse the 2 fans on the 620 to suck cold air in, and re-site the side fan to the top as a second exhaust.

andy_mk3 · 7 Nov 2011 at 01:06

I can't fit another fan at the top as the rad gets in the way unfortunately!

Edit: just seen your post Rooster, I'll give that a try and see how it goes, thanks

Same prob with my h50, been looking into 12mm thick fans, but heard theyre arent worth it, until then my p/p will be exhaust instead of intake.

I did the same on my CM690 II (Left side fan off). Not noticed any bad temps, so I'd go with above too.

The only think with swapping the rad fans round is that then I'd only have one fan as an exhaust, would that be an issue?

PhillyDee · 7 Nov 2011 at 21:11

You need to look at temps overall. Also, what about the PSU, Thats always an exhaust.
Reversing the rad fans will give a drop in CPU temps. However, it will raise the internal temps including graphics card.

andy_mk3 · 7 Nov 2011 at 21:23

The PSU fan does nothing in relation to the case, it sucks in through the bottom then straight out the back.

I've just swapped the rad fans around and CPU temps are exactly the same, the load temps are maybe 1-2°C lower but that's it.

How can you stand the noise the fan on the side panel makes?

saitrix · 9 Nov 2011 at 19:03

Why not try a negative pressure setup? Minimise the number of holes on the rear of the case, and only run the extraction fans. It will cause a low pressure inside the case, sucking in cool air from infront of the pc. Plus that way you don't have any fans at the front of the case, which will make the pc quieter.
