lmfao! nice d34th

 

[Turb0Yoda]

btw.. ouch... and nice beard

 

[azzazel_99]

Lol the beard is something my wife makes me have. Im trying to see how long i can get it lol.

Why the heck not I suppose ahaha

 

[azzazel_99]

Since i can't do much else with my t-rex arms i figured i'd tackle a little cable management yesterday

 

[turkey3_scratch]

That's really nice management! It always baffled me how the 1000W and 1300W G2s have red cables in addition to the normal black for some unknown reason.

 

[azzazel_99]

Yea i fixing to change the color scheme to blue from red so im going to have to use the black cables ugh.

 

[turkey3_scratch]

I may be building a normal machine for someone to use casually, but I want it to be quiet. What concerns me is that the case-included fans may be too loud, or the PSU fan. What do you guys think?

I just built my Mom's new system in that case, and may even have used that same PSU. The fans are not loud if they can be controlled. The fan header I tried first could not control a 3-pin fan, but the other one could, which made a big difference. She's getting an i3 but with the copper-slugged G3258 cooler on it.
The PSU fan is quiet.

 

[turkey3_scratch]

Are you sure you used the same PSU? You say "may have used that same PSU"? But that's good if it is quiet, that is good. Does this case include 1 or 2 fans?

Perhaps I'll just grab a nice Noctua or something.

 

[Onus]

I'll have to check, but I've used a number of those low-end Seasonics, and they all had quiet fans. The case fan is quiet if not run maxed, which it was until I found a header that could control it; it's fine now.

 

[turkey3_scratch]

Hmm I wonder if one of my headers can control it on this motherboard. I'll check the manual.

 

[turkey3_scratch]

Motherboard has only 1 fan header, so I'd have to use molex or get a splitter...

 

[Onus]

A simple rheostat fan-controller could be used in your case. I rarely need them, but some Rosewill case fans I've bought came with them; Thermaltake too iirc.

A splitter should not be an issue with low powered fans.

Your boards second 4 pin header(SYS_FAN) is a voltage based and non PWM based controller so at least it will control almost anything. I do not know why board makers choose this over a normal 3-pin since 4 pins will connect to 3 pin headers fine.

If you have PWM fans, a PWM splitter with molex power will not work because the PWM signal is not used on that port.

If the system runs cool enough(and it should). You may be able to just runs the fans on straight 5 volts(as long as they start on 5).

I like the idea of a basic fan controller as long as the user will remember not to turn the fans too low or off(most fans need more voltage to start, but can be lowered after spinning). I would not give my family members(they are not computer people) manual control just in case.

 

[turkey3_scratch]

How can a 4-pin header not be PWM?

Let me get this straight. Two pins are for operating the fan itself. A 3rd pin is for getting a reading from the fan's RPM. 4th is for PWM signal, correct?

 

[nukemaster]

Many board makers use voltage control one 4 pin headers. I have no clue why they do this(it does allow compatibility will ALL fans so that may be the reason).

On a 3pin fan with control you have
ground(-) | variable voltage | Tach(speed sense)

On a 4 pin with PWM you have
Ground | 12 volts | Tach | PWM signal

These 4 pin with voltage control have.
Ground | variable voltage | Tach | VCC(most times 5 volts. this tells the pwm to go full speed. it is like a 100% cycle)

It works, but will not work with PWM splitters that get 12 volts from the molex because your fans will never get an actual PWM signal. This leaves them at full speed.

Here is your boards setup.

You can see the SYS_FAN header simply controls voltage and does not actually provide a PWM signal. The CPU_FAN does however and can be used with a splitter IF you had PWM fans.

A 3 pin or 4 pin splitter that does NOT get power from the power supply(LP4/SATA) will work fine with either fan type. Just do not use high powered fans and watch out for splitters that split the tach/sense wire since that can cause speed reading errors(the board is getting feedback from 2 fans instead of 1.).

 

[turkey3_scratch]

Okay, thank you for that info. So to be clear, if I buy a female to 2x male splitter fan cable, that will do the trick, and I will be able to control fan speeds via voltage in the BIOS, correct? because I'll have two fans to power.

What is even the benefit of PWM compared to increasing and decreasing the voltage?

 

[nukemaster]

Yes a splitter should work as long as the 2 fans are not more than a header can take. While most boards are good for about 12 watts(1 amp). It is best to contact the board maker when confirmation is required. I have used these splitters(or just made my own) many times with low speed(under 1500rpm) fans without issues.

It is more efficient, claimed to be more quiet(but that is has been disputed before. Even worse with boards that do not keep the signal fast enough to be out of hearing range) and has a wider range on supported fans.

While a normal fan "may not" start at the lowest setting, ALL PWM fans should start at even the lowest setting when getting a PWM signal. This is because the fan maker determines the minimum speed(and they KNOW the fan will work at this speed).

Most PWM fans once they hit the bottom speed will not go any slower(I think it is part of the standard, but do not quote me on it). Voltage controlled fans may stall at some point and fail to start on low voltage.

It should also reduce the chance of header overload since the fan is just getting 12 volts. Normally slowing it down involves a regulator that gets rid of the extra voltage(as heat for a linear setup). The PWM pin does not feel a load as such either(under normal operating conditions) it is merely a control signal.

Sooo I play alot of division and so does my wife................I started this and am not sure where im going with it but this is the "dark zone" Setup

 

[Bossyfins]

Haven't posted much lately. Been busy. Couple things:

- Bought a P3D Academic license w/ an aerosoft a318/319-a320/321
- Dad sold his cargo van (which was a true mistake). That thing was used for construction work he did, and w/o we were lost lol. So we bought an 2002 f150 that is CNG w/ a carpool access sticker
- Reinstalled windows on my computer after some virus or something made it slow
- Upgrading's sisters mac to a 512 gig SSD soon
- moving to Cox ISP w/ 15 down 2 up
- Looking into a new car that replaces our leased 2013 Prius. (We did register for a Tesla)
- Ate a bacon burger.


Now I am bored since I literally have nothing to do at home during spring break.

 

[Turb0Yoda]

Is that the prius with the really bad tires?

 

[Bossyfins]

Yup!

Damn Angels off to a crap start...I was at the home opener and left in the 7th inning...
