I've read through most of this thread waiting for my case to arrive; and in the mean time as well I have been considering some cooling strategies for the case. I'd like to float some cooling ideas by you guys for any kind of feed back.

As you can see bellow I made a rough mock up of the general layout for the idea -- I hope it helps a little but let me try to explain.

The key bit is 1): build a main duct for the CPU HSF itself -- isolating the air flow for the RAM and CPU. What I'm putting forward is the idea is using the venturi effect and positive displacement to increase both the power and efficiency of the cooling system.

My hope is this design might give increased cool air pressure to the ram and HSF without needing to increase power consumption from stock values.

To explain my thinking here is that, thanks to the venturi effect, the cooler air will be compressed and so flowing fast over the ram and into the cpu's heatsink fan (HSF). Then, once heated by the HSF, the air expands creating "positive displacement" -- ie: additional pressure for the exhaust.

So in this case, the positive displacement would be free, since the air is getting heated by the CPU's wasted energy anyhow. Could also think of it like a jet-gas pump, using the CPU's waste energy to create the air pressure for the exhaust.

If it seems like an idea worth trying I'll start by switching the 120 cm case fan from the back to the front drive bays to give us the intake pressure.

The second bit 2): is sort of tossed in on the side. Nothing interesting -- just a short intake duct to the GPU; since the GPU also exhausts in the case and the front fan doesn't offer it much air at all I figure I'll give it a little TLTC (tender lovin' thermal care) too.

(btw not my case in the img ...waiting for my CM Scout to arrive in the mail!!)

As for materials: maybe 3-5mm mylar and packing tape (considered possible static issues); attached to the case along the top it shouldn't be a concern.

The only thing I see that I would do different is the side panel. You'll probably get better temps with it just as a vent rather than having a fan in it. You'll need to try it both ways to know for sure, but that has been my findings on most cases.

Same here with my HAF 912 case as the temps are roughly on average 2 - 4 or so degrees celsius hotter with a side panel fan and much better just being a vent.

Interesting about the side vent; I was going by the testing done here: http://www.hardwarecanucks.com/forum...review-12.html

Further I thought the addition of a mylar duct to the gpu would also help ensure the cold air gets where it needs to without getting pushed and pulled by the air that's already moving through.

It's possible it would work, but it would depend on the gpu card itself. If it is a single slot card you have a better chance of it working. It's doubtful that a dual slot card would benefit though as most of the testing I have done has showed.

As for a cpu cooler, ONLY if you have a cpu heatsink that blows down onto the motherboard like the one they show in the case. With a tower heatsink a vent is often times useful, but a fan will normally have absolutely no effect at all, or will cause the temps to go up since all it does is disturb the airflow. To date there isn't a downward blowing cpu heatsink that can come close to the cooling efficiency of a tower heatsink even if you have it drawing air directly from the outside of the case. They are useful in cooling the components around the cpu, but at the cost of higher cpu temps.

Yeah I was wondering about the heat sink in that regard. I'm starting off with the stock cooler on the i5 2500k (so it's like the one in the pic). But my assumption is that by increasing direct airflow through a tower HSF I will also see performance increases there as well.

The more interesting part to me though is the proposal on better utilizing the intake and exhaust pressure differentials to increase that airflow without added energy expenditures. That's the bigger and more important question for me I think. One could put a fan on one side of the tower and one on the other inside a duct and it will increase airflow over the heat exchanger; I just want to try to tweak that idea a bit further to make better use of the energy already being used by the heating/cooling system.

I haven't seen any data on the use of pressure differentials like the venturi effect and positive displacement to help cool a CPU.

But I know for pumps in general these can be very effective for a wide range of applications. In this case it might be too small to make any difference. IDK

I recently worked as a consultent for the engineering staff at the Vancouver Int Airport on their geothermal heat exchanger system. There we were experimenting on new ideas and applications in order to save on cooling the entire airport; spent about 3 million in RnD (before I got there). It's not my area of specialization so I can get kinda noobish with details here and there but I found a special love for the creative side of mechanical engineering.

You might see a 1C differential by going to all of that trouble. I seriously doubt you will see much more than that. I've tried similar approaches in the past on other cases and didn't find the results warranted the time involved or the complexity. They used to sell air ducts to allow one to do much of what you are talking about, but they never went over as they just didn't perform as well in real life as the creators thought they would.

Tyranny and Liberty.. Mine just said SAFE... SEMI... AUTO..... I am a Left handed shooter so I had to learn a whole different way to shoot. The Ejector would throw the blazing hot Shell Casing into my Shirt sleeve, burning my forearm. So I learned to shoot with my right elbow at 6:00 instead of 3:00. It actually helped improve my scores to marksman. But I think what really improved my scores were not getting burned by the blazing hot ejected casing. LOL.
