For those who use antec P193, any1 modify the fan to 200 mm?

I really like those 200 mm fan, the only cases that c/w 200 mm fan is the Zalman gs1200 and this ANtec P193. The top fan is 2 x 140 mm fan. Now, on the Zalman GS1200, they have a 200 mm side fan, that you can convert to 2 x 120 mm fan. So I thought if the top of the Antec can fit 2 x 140 mm fan, sur...

Re: Nanoxia Deep Silence 1

how can there be in flow of air, when that front door is close? As you can see, usually that door is meant to be closed

anyhoo, why is all these cases all have their power supply at the bottom?

I dont' know what cavity resonance is. But I didn't notice that w/ my Nexus, or at least it is not noticeable. Is it the no. of blades? If not, what causes the difference btwn. nexus and scythe?

Update

Alright, I gave up. I spent 4 hr. today, and about 1 hr. yesterday on these Scythe fans, in the end, I stayed w/ my Nexus 120 mm fan at 38.87 CFM. This is what I done: I heard the actual noise of the Slipstream 1200 rpm (24 dB), and 1900 rpm (37 dB). Surprisingly, when I walked 2 ft. from the comput...

I can't drill a hole as that's exactly the hard disk is. Just behind those metal is the side of the hard disk. There is gap between ea. hard drive, so as long as I can get a fan there, I can blow the hot air out. The question remain how to secure a fan there? I can put 1 of the drive on an empty bay...

The plug on the Scythe fan is the standard design, (edit, to be clear it is the standard PWM design) therefore the pins are as above. The header on your motherboard is not the standard design. This could be for many reasons, but one possible reason is to stop people connecting ordinary fans. Where ...

You can also skip the hassle of using the plug on your motherboard and get a small fan controller and use the molex plug like your origional fan was. Lots of options :) there is no bay left for fan controller, so if I use a molex, I would get a non PWM fan at silent speed, I am thinking of the scyt...

We have a situation where either Scythe, your motherboard's designer, or you have made an error.

I think you've misinterpreted. As long as your fan was made for a PC (which is true of the Scythe you're talking about) both types of fan will always work with both types of header - 3-pin and 4-pin. It's just the wiring colours which may vary, although in practise what this really means is that yo...

The question of how much CFM you "need," whether at the front or the rear, is a bit meaningless without knowing your component temperatures. The fans are there to keep your temps within acceptable limits, not to generate airflow for its own sake. I called HP, neither the bios nor any HP software do...

I am the one who actually do the calculation. They list the CFM is cubic m as 3.68, so we I divide by the Cube of 0.3048, the no. is 129.957 CFM

I can't replace the rear fan. I can't find a pwm fan less than the spec. 50 dB that gives more than 130 cfm.

The issue of multiple vs single fans is clear with the Nexus 120. Two of them at 6V move as much air as a single one at 12V, and make 2-3 dBA LESS NOISE!!
I wonder what happens if it were 2 fans at 12V, would it also be less noise?

But you can see from the photo above your post (the photo is a Scythe PWM fan) that the offset will NOT fit the red socket (Photo 2 of my very first post)

With any amount CFM and impedance on exhaust fan blowing out of the case, air will come any hole and opening of the case as its negative pressure. This means it will become front and sides and every little hole and opening. You can put your fan in front but I doubt you see much of the temperature d...

Looking at the photo of the header, you'll see the upright key is sized to locate a 3-pin plug onto the correct three header pins. Are you referring to the red socket?
