how exactly can you run 2 power supply in 1 computer? And how can there be space? Does any1 has photo of rig that embedded 2 power supply?

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...

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?

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...

Neat trick. Thanks for the tip

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...

on this link, they said the nominal temp. of hard drive should be 40 deg C

http://img171.imageshack.us/img171/1870/speedfanod4.jpg 1) what is the normal idle temp. of hard drive? As mine ones are at 35 C, 38 C, 38C, 36 C 2) And what is Temp1 & Temp3? If my GPU is 56 deg C, what temperature is Speed Fan reading that says 53 C and 30 deg. C 3) Is GPU 56 deg C high? It's an ...

do they all monitor everything? including cpu, hard drive, MB. I am not verse in those software so I don't know which one is good

I already download and run Systool, it won't recognize my motherboard. I am using HP Workstation. but HP themselves doesn't have temp monitoring software, neither on their BIOS nor any of their utility software Needless to say, I can tell my GPU temp. But I like to know my hard drive, motherboard an...

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 ...

I don't know the temp. of all of the above. I was hoping to use SYSTool to read it, but Systool said unrecognize MB. HP doesn't have any software to read the temp., nor does HP BIOS. If you know a software that can read a HP motherboard, Hard drive, CPU. Let me know I don't want to cut the fan grill...

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 doubt Scythe or a motherboard designer would release such basically incompatible products with no furore, so, logically, your spatial awareness is at fault. :shock: I was confused by the above pin dia...

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 HP XW9300 is a 700W power supply workstation, the very high end from their end

since HP engineer spec. out 130 CFM, I don't want to dispute it

first of all, thanks for the info. My existing fan is using the big hard drive type socket plug (the big one in the above photo w/ the blue color background) so I never have that problem. The reason I want to buy a fan that uses PWM is 1) to have the computer control the speed for me 2) If I get a 1...

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...

129.957 CFM?! That's enough to float a small hover craft! THREE decimal places -- I smell marketing bullpuckey.

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

If my rear fan that comes with the system by the manufacturer (HP) is a: NMB-MAT PWM fan 129.957 CFM , 3600 rpm, 12V, 50 dB fan. I also have 4 hard drives (2 x Ultra SCSI, 2 SATA) at the front but NOT directly at the front cooling fan spot, but just above the 12 cm fan spot. See photo where the gree...

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)

Unless Scythe has a header like photo 1 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...

How fast does the rear-fan usually spin? that I don't have an answer. It is default to LOw on the BIOS, and the truth is, it's quite quiet I have about 2 ft. from the computer. Now, when I play a game like Jet N Gold, the whole damn thing goes at max. speed, and I can hear the fan noise even the so...

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? Is the pin socket plug a Standard PWM plug? Because the rear fan plug is not standard PWM socket plug (see 1st top photo where the ...
