Aircooling how far is too far?

post #1 of 41
Thread Starter 
Recently upgraded my rig, and well temps went through the roof, so being short on raw cash to throw around I've decided to see what I can put together cheaply.

So heres what I'm looking at.

Rocketfish Full size tower in the mail. Due in tommorrow!
1.5 Horse Power Terbine(SP) Greenhouse cooling fan, pushes about 1200CFM and about 5Pounds of pressure.

Odds and ends of old case fans.
And quite a selection of tools to be used to mod my incoming case.

I'm in no way great at well understanding what would work well for airflow.
But I'm hopeing someone here can tell/advice me as to what would be best towards modding and adding to this system!

I'll post pics tommorrow, and maybe update what I have access to in the way of hardware.

Hopeing that this could turn in to a bit of a off the wall extream setup for aircooling, but than again I'm not sure all what can be put towards it.

So someone out there throw me your comments, I'd love to have a little bit of a helping hand, and I'm sure someone might find it intresting towards the progression of this project!

Can't wait for the pix!

Only thing I would be worried about is too much CFM. If you put it as intake I would be worried of it damaging other fans//components. That said, I think it should be for exhaust.

That was my worry, though I'm debating having it switch on under high usage, or maybe just have it be my only solid cooling unit.
The problem, though till I have the Rocketfish in my hands, as I see it is well that 1.5horse takes up a huge amount of space!

Before going nuclear with your battleplan, ponder this:
You have a X2 6000 with a "stock" cooler, whatever that is.
Your cpu is 125w.
Your cpu is very hot to begin with.
Try replacing your heatsink with something better and then see how bad it really is.

Agreed, but being that theres quite a lot of "dead" air in the case, and this kinda helps determine weither to get a fully passive massive heatblock for the CPU or not is what I'm pondering.
If I go for something that is ideal for dealing with the heat form the X2 without fans, then what I have is a decent performer, and when I tack on the massive amount of airflow that I'll be blasting towards the mobo, I'll cool that heatsink without any problem.

On a side note, passive cooling might be the best idea, I'm figuring if I go out and find some electrical grade 1/5" thick copper roding I could basically cool the whole mobo, by making a giant heatsink and connecting it to various points around the while rig. Conductivity might be a slight worry but I can settle that later, its just an idea though, so it might not be the smartest thing to do.

The more I think about it, what I'm aiming for is well to see how far I can get passive and air cooling to go.

Sure you can reach sub par temps equal to WCing, with some massive CPU heatsinks, but can I do below that and possibly for the whole case, not just the CPU? Updating first post with pics!

Well, given that you'll be pushing 1200cfm through the case, i'd say that you should go with all passive cooling... try something like a IX-14, because of its huge surface area for the cpu.

as for the coper rodding all over the mobo... not to sure how that would work... to cool effectively you need alot of surface area (aka fins), and with out that, then the copper is just transferring the heat to... nowhere really (also note that heatpipes aren't just pieces of copper, its more complicated than that) so i'd say stick with some good passive coolers and give it a shot.

Hmm, Duke ponders what his CPU temps would be if he ducted that blower to his HS

I was under the idea that with piping I can basically add fins, though not as great as an actual store bought heatsink, but the idea is with large amounts of copper tubing, I'm pulling that heat off the Mobo, and getting it to more open air, with the massive amount of airflow I'll have flowing through the case, wouldn't it therotically(SP) cool those pipes(I could actually just do hand made tinfoil/copper sheeting covering most of the pipes) and the said fins; leading to much more overall surface area.

On a side note, I'm going to have to look into what your saying as to heatpipes being different, I understand that the big thing is the contact surface, how smooth and flat it is. But copper will pull some heat no matter what, sure I might not get machined quality heat transfer but any will help.
I'll do a little photo shop later today to show what I'm thinking, still have to figure out how I want my intake and exaust to work, might just do some drilled holes throughout the case to get proper air movement.

You're right, any more surface area will help as just plane old copper will still transfer heat, its just not as effective as a real heatpipe with some good fins(heatpipes are hollow pipes filled with a liquid/gas mixture... thats what makes them work so well). Its just that I imagine that it will be hard to mount the coper tubing to everything, but yes it should still help... and since you're on a budget that totally makes sense that you'd want to do it that way. I'm looking forward to the pictures/drawings... that should help me envision what you're saying.

UPS bumped my shiping back one day not even sure why...
But anyhoo till then I can't really cut anything into stone.
What I'm looking at, from what I can tell on pics, the fan is going to have to go on my side door as a inlet. It is possible to have it as an exaust, but I'd much rather have the air forced onto the heatsinks.
As for location I'm debating having it blowing onto the Mobo, the only problem with this is, the fan itself being a good 5lbs, is going to have to be suspended in the middle of the door to properly blow onto the mobo. Nothing that can't be fixed with a little bit of scrap metal lying around but still could prove to be a challenge.
As for heatsinks looking into getting something for the CPU, the IFX-14 from thermalright looks like quite a beast though on the pricy side, might end up with a 120 or 90.
as for custom heatsinks I'm debating adding them on or not.
The Asus Mobo I have here has passive north and south bridge cooling, I could probably easily tack on some copper and give it a little more surface area.
And could possibly do the same for the CPU heatsink.
Now for the Vcard, from what I can tell on the stock heatsink I'm probably going to leave it alone, the 8600 though Oc'ed doesn't put out to much heat, and I don't think the card could push out to high of numbers weither I lower its temps by 20c or not.

On a side note, Harddrive cooling? Why? My 2 250 WD HDDS don't seems to every have any problem? Is it just novel thinking or do they have heating problems that I have completely overlooked?

Air venting is going to be the biggest problem, Though I don't have a pic for this, I think its quite easy to explain.
Either on the front door or the one behind the mobo, I'm thinking either I can do a bunch of holes, which well won't look to great. OR something a little more ratical I could basically cut 2 - 4 rectangle boxes out of the door, then if I do it properly hinge it so that they sit closed, and if cut right will be very hard to see, but the effect will be, turn on fan, if I have a lot of pressure in the case from lack of exaust = those rectangles will open up like gills on a fish, allowing air to flow out, and well when I turn off the main blower they should close right back up.
I'll have to see how possible it is, and well it would be quite intresting, but than again its just a thought that poped up in my head. The other possiblity I'm looking at is just having a strip of fans running from top to bottom blowing out, I could do it for the most part on the back, though some spots might not be perfect, or I could do it on the top.

BAM WALL OF TEXT Sorry!
