I didn't comment on the pic yet because I can't see it from where i'm at right now, my employer has that site and a lot of others blocked right now. I'll take a look a little later.

Irene have you considered a Drive Bay Fan?

DRIVE BAY FAN:

I have used one for a few years... They are pretty quiet and do help!

One of them took air IN... and it was quiet, one spit air OUT and that was louder.

I placed it on the floor and had my microphone on the desktop... with a GOOD microphone and a GOOD cover for it you could NOT hear the fans!

Hi Rook!

I am going to use the drive bays creatively, like my picture illustrates. The "HDD cage with fan" I am referring to in the picture is the Lian Li EX-23N ( http://www.lian-li.com/v2/en/product/pr ... dex=12&g=f ). It occupies two drive bays, the case has four drive bays. I will need to throw away one DVD drive so then I'm left with my primary DVD drive and the DAT drive. However it will not help as much in my situation as the drive bays are way too up to bring in cool air to the CPU efficiently, but the HDD cage fan will help keep the inside of the case cool (my SCSI drives don't run hot; even in this case now without a fan they run at around 39C).

Rook, don't understand me wrong in this point. You call that a good microphone, I call this a good microphone: http://www.akg.com/site/products/powers ... ge,EN.html

However, I have this microphone: http://www.akg.com/site/products/powers ... ge,EN.html

And yes I feel much more poorer after buying it ^_^
By the way, send my greetings to your wife! ^o^

Irene I got you!

I wouldn't plug that thing directly in to the PC though... use a mixer board right?

Li Mei sends back a big HELLO! And asks me if I have flirted with you often!

:P <-- for my wife! (I love her too much!)

:D

@Irene;

Just looked at your air cooling/flow project pic. Looks like a plan. Looks good so far, but just for giggles when you get everything in place try it without the bottom intake fan and then with it to see any difference. The reason I say this is because of the placement of the front fans in relation to the bottom air intake fan implied position (from the pic). From the pic it looks like the bottom air intake fan air flow might negate the front intakes some by disrupting their air flow towards the CPU area.

Also, get the highest CFM fans you can for the front intakes.

Oooo...ooooo...ohhhh...I just had a thought too...a duct! A duct to direct the bottom air intake fan flow to the right (in relation to the pic) and up then around back towards the top of the cards. If it was done properly it would add to the air flow from the front lower fan and increase the cooler air volume in the general CPU area. Your plan would still remain basically the same for exhausting but the volume of cooler air would be increased in the CPU area. But thats just me, not sure how well that would work without testing it out first, but you could try it by coming up with a make shift duct of some type just to test it out. The duct would come from the bottom intake fan then to the right and curve around in a short but smooth curve (corners waste energy and thus air pressure which is the energy we are dealing with here) and end under the lower front fan but pointed in the direction of the CPU at such an angle that the bottom of the duct points in a line with the right edge (from the pic view) of the upper card. This would also keep some of the bottom intake air from being sucked back into the front fans (but that amount is going to be small anyway.). The only problem tho with using a duct there is the space is going to be kinda cramped for the curves needed. Once you got away from the fan its self the curve needed wouldn't be so bad, but at the fan it would need to start over the top of the fan and curve up and away from the fan to the right in possibly a higher curve. Anyway, its a thought, 'cause my instinct here is to mod, and thats what i'm starting to get into thought wise. Now you know why I test my modding out on mock ups :), sometimes something that looks good on paper, in thought, or in a pic doesn't turn out as planned. So just ignore the duct thing for now and go on with what your doing, but remember it if you want to just test the concept out some. Creating ducts can be very difficult, sure you can rig something up with cardboard and tape and stuff but they look ugly when thats done. Some times you can find what you need in plastic ducting in the form of hoses and things at the local hardware store, most time your left with creating it yourself. I've done custom ducts before, created the molds with plaster or something and then used thermo-plastic (available thru modeler hobby supply places) and molded them but its a lot of work and if you made a mistake you have to start over, so I wouldn't recommend a duct at this point (even though to me its tempting to look at.) :)

Hi SFSxOI and thanks!

Will place an order on the fans as soon as I can, but I need to wait for the WaveAir to hit the markets here as it's still not available ~.~

I now understand what you're saying. The picture of the airflow in the Nexus Breeze on Nexus' site looks extremely good on paper, but real world hello hello it doesn't work as expected. Will keep you informed when I have the parts and start modding! But for now I need to study hard, the exams start next Wednesday!! O.O''

BTW, and still on the fans topic...

Anyone knows any good way to reduce dust intake by the fans?

The more fans there are, the more dust is sucked in...

I usually have to do a full clean up every 6 months :roll:

Pantyhose :oops:

I use washable fan filters on all of my fans. Nexus sells fan filters (good ones). They blobk 99% of the dust very effectively but be prepared to clean the filters themselves more often to avoid the situation where the dust blocks incoming air. It is very easy though, take the case out, wash the filter, put it back in, voilá! A much more cleaner PC.

Cheers.

a panty hose screen does a decent job but its flat and once the dust blocks the space in the mesh its efficiency drops. Something else also is go to your local Home Depot type hardware store and you can find black foam mesh type filter material in the "cut to fit" central air filters. I picked up one last year for about $6.00 and I cut my filters from that. You can also find the material by its self. Its washable, reusable, moldable, and durable, and blocks at least 99% of the dust. It does a great job. You can cut enough filters from it for at least 20 computers, so your going to have some left over but as cheap as it is who cares. :) The black mesh filter material is about 1/4 inch thick at most, but its advantages over panty hose is that the dust doesn't get trapped in such a way that it blocks airflow like panty hose does plus it statically traps the dust which means less blockages to air flow and better dust trapping. Unless your in an extreamly dusty environment you shouldn't have any problem with the foam filter material. Normal housekeep and cleaning in the room in which the computer is located should help a lot with any filter. I take my machines down in the last quarter of each year and clean them, most times I don't find any dust at all and just wash the filters out and put things back together, if for some reason I do find dust its of such a small quantity that a quck swipe with a piese of sticly tape takes care of it. If you already have filters and you see any sign of dust on the fan blades its a sign of one of two things - either your filter isn't doing any good or you have a leak thats allowing air to slip around your filter and into the fan, in the second case it probably also means you have a case leak and your air flow in the computer is not as effective as it could be. Remember though, you can have all the filters in the world, but if your case leaks at the seams or where pieces fit together your still going to have a dust problem in the case.

Darn ! I didn't know there was an exam for case modding. :)
