CPU_FAN (4pin) CHA_FAN1 (4pin) CHA_FAN2 (3pin) PWR_FAN (3pin) Anything plugged into the first two can be set up using the optional Q-Fan2 feature, which has to be enabled in the BIOS and then has an interface that you can access in Windows to set up profiles for those fans - one for minimal noise, one for maximum performance, one to vary fan speed with temperature. I admit I'm a little confused as I'm not sure whether the two 3pin headers provide no variation in fan speed at all, or provide it but without the user being able to set up profiles for them the way you can with the 4pin Q-Fan2 headers. :06: Quote:
I found a splitter at Newegg designed specifically to allow one 4pin header to control two case fans... only one "reports" anything to the mobo, but both get the same regulation based of what the primary one reports. Since they make the cable for it, I kinda assumed it was doable. Hadn't even seen fans designed to daisy-chain like that but I guess that means it's definitely an accepted option. Actually now that I look at it again, the manual just recommends plugging the rear exhaust fan into either the CHA_FAN1 or CHA_FAN2 header, it doesn't specifically say to use the one that works with Q-Fan2. Originally when I thought the rear fan was supposed to be used with Q-Fan2, I was thinking about what someone (maybe you) said about not having exhaust fans pulling more air out than could be pulled in so I thought maybe I'd better have one intake fan that was getting the same regulation as the main exhaust fan. But maybe I'd be okay with one 4pin fan on the side over the GPUs that can rev up and rev down as needed along with the CPU fan and just plug the rear exhaust fan into the other CHA_FAN header and let it do whatever it does from there. Oh in case it matters, the overall fan setup is: 120mm front intake 120mm side intake x 2 120mm rear exhaust 140mm top exhaust I'm assuming that's what I want, air in through the front and sides, and out through the back and top. That's not counting the PSU fan but it's only really pulling air into the PSU through its own dedicated vent. Do you recommend using the mobo fan connectors in general whenever possible, as opposed to running power through 4pin molex connectors from the PSU? I mean if it's not an LED fan, I read somewhere that those shouldn't be connected to the motherboard. |
Got everything on the board; 200mm front intake, 200mm side intake, 200mm top exhaust and 120mm rear exhaust. The PSU is in it's normal orientation, intake at the bottom. Draws air outside the case and exhausts directly. 2 of the big ones have a LED as well (I know Jan, didn't get them for that, that's just how it came :O: ). Plus a 120mm and 92mm on the CPU.
I doubt they would make case fans that exceed the power requirement a board connector can supply, to be honest it's the first time I've heard of such a possibility, but if you feel more comfortable using molex you might as well use that. (in other words, haven't got a clue if it matters :hmmm: ) It creates some overpressure inside the case, which arguably helps keep out dust, but only the front intake is filtered so that's not really applicable in my case (pardon the pun). |
Frau Kaleun,
if you have fans with 3 pins and you want / need their speed controlled (maybe too noisy) this little guy does the trick: http://ecx.images-amazon.com/images/...500_AA300_.jpg On Amazon.com I hope this is available in the US :O: I used them myself and put them into some friend's rigs. I'd give it 9.5/10 |

I am perfectly happy to plug everything I can into the board if possible. Not sure where I saw the thing about LEDs not running off the board, it might have only applied to a specific board being discussed in something I was only looking at for fan info. I don't think it was in the manual for my mobo. Quote:

I believe my LED light bars are run right off a power supply plug. I can take a look if you want.

I have two LED fans I was going to use but the second one would end up in the back as an exhaust fine and I'm not sure I want it there since I've already decided against LED fans on the side. I may just send the second one back and use something else. I'll have to see how it looks this weekend when I get in there and start hooking more stuff up. |
Couldn't wait till Labor Day huh ? :DL Don't blame ya. :haha:
My BP would climb thru the roof and would slowly grow hard to be around. :D...:yep: Just take your time and always use wrist strap.:yep: And Most Important. Stand back every once in a while. And ENJOY build. :D |

The actual putting together of the computer itself is not the part where I need the big blocks of uninterrupted time, almost all of it can be done ahead of time in small increments (and needs to be done or at least considered thoroughly as I still have a couple decisions to make about what I need and/or want and will have to order online). The only thing I really can't do until I'm ready to complete the switch is pull the HDDs out of the current rig, because I need this rig to work until I'm ready to start up the new one in its place and get the OS installed and critical backed up files restored. Everything else that's coming out of it can come out of it at this point if I want to take it that far, I've either got something to replace it with or don't need it in there any more. |
Understood. :salute:

Since I have no clear panels or windows and the case sits back in an alcove I can't see the point of having a lot of LEDs shining out the vents where the fans are, I think that would get old really fast. Anyway I've got almost everything in there except the stuff that won't come until next week and that's stuff that would go in last anyway. I do have both optical drives and two HDDs in with all the cables hooked up plus the power/SATA cables for the last HDD are in there in position just waiting for the drive, and my front panel USB hub is in place just waiting to be hooked up to the adapter I ordered. I'm really glad I got a case with a horizontal bay for the HDDs, it's so much easier getting the drives in and it leaves extra room for cables to run up and down inside the case without them curling up in front of the mobo and blocking air flow. Where I can't run them outside the drive bays and back in I've got plenty of space to run them up and down without blocking the big vents in the HDD bay, and since every other spot in there will be empty there's some good airflow from that front fan. I was concerned about it but when I fired it up I could feel cool air blowing over and under the drives and on through to the rest of the interior. Combined with the two side fans blowing air straight onto the GPUs and mobo I think it will stay plenty cool in there. Having the PSU on the bottom helps a lot too, any extra cable just coils up in the extra space in the bottom of the case without blocking anything that needs air. And I'm not fighting gravity with the big ATX/PCI-e power cables. :yeah: |
My computer sits on a shelf underneath the desk. I have a pull out keyboard shelf and this blocks the bright blue lights that shines up towards my eyes. Although the lights look cool, a darkened room the lights can be a distractions. I did have one burn out and did not replace it. If the other goes I will not replace it either.

The Day of Days is fast approaching!
The only thing I have left to do (I think) on the new rig is to put the last HDD in, which is currently the boot disk on this computer... so I will be starting to back up the few things I need to back up from it (most stuff is already on or backed up to an external drive, yay). I will probably shut this thing down for good tomorrow and put the drive in the new machine and then... we'll see what happens. :O: |
Well then the world will explode... thought we already established that? :O:
Best of luck, few things are as rewarding as putting the thing together and firing it up. :salute: For some people anyway, and assuming it doesn't explode. |

Eek I just remembered I gotta decide what I want to do for paging files, I made a separate partition on one of my current disks for that but left the boot disk 'as is' (except for tinkering with the size of the paging file) because I didn't want to fool with trying to repartition it. If I'm gonna create separate partitions on each disk this time I want to do it in the initial setup. |
