jrockz Posted March 8, 2014 Share Posted March 8, 2014 Hey guys, I have an H100i and a pair of Noctua NF-F12 fans. My question is it safe to use the Noctua's Y splitter to join the two Noctua fans and connect it to the L.N.A and then connect that to the corsair splitter so it can plug into the brick? The lowest RPM Corsair link would let me go down to is 980RPM on silent mode so I think it is due to the fact that there's no LNA connector attached. Should i just connect my two fans straight into the mobo and control the fans using fan expert on my Asus Maximus Gene X IV? I do like Corsair link and i think it is a lot more better than Fan Expert so if possible i would like to somehow connect the Noctuas into the Corsair brick.

Latharion Posted March 8, 2014 Share Posted March 8, 2014 Are the Noctua NF-F12 fans 3-pin or 4-pin (PWM) fans? If they are 3-pin, then using the LNA connector would help because 3-pin fans are voltage regulated. 4-pin fans would possibly work o.k. with the LNA connector, but because Corsair Link expects a consistent voltage to do it's work (that's how PWM fans work), limiting the voltage limits the upper potential of the fans as well as the lower potential. With PWM (and specifically Corsair Link), the software has a hard limit of 20% minimum RPM on the fans (probably to keep problem incident reports to a minimum). So short answer is, it should work fine, but keep in mind that the max output will be hampered. Also note that there is a limit to the amperage that each of the connectors on the block can handle. Basically, add the amperage of the total number of fans connected to each of the headers and make sure it's less than the limit. I cannot remember the limit off the top of my head, but search for it here on this forum and it should pop up. It's been answered before. FYI by headers, I am referring to the connectors located on the block, NOT each connector on the Y splitter. Link to comment Share on other sites More sharing options...
jrockz Posted March 8, 2014 Author Share Posted March 8, 2014 Thank you for your reply. The Noctuas are 4pin connection. The main thing is noise and I want silent when im not gaming so I hope attaching the LNA connectors will help. There just seems to be a lot of wires that I have to connect in order to put the LNA wire so it can go into the block. 1-two fans into Noctua y splitter 2-y splitter into LNA 3-LNA into Corsair y splitter 4-corsair y splitter into block Thats a lot of attachments so I just wanted to make sure theres no problem with that.

Doner1626864112 Posted March 8, 2014 Share Posted March 8, 2014 I have two Noctua NF F12s attached to one y splitter and two other 140mm Noctuas attached to the other. The 140mm are in the front of my case and not connected to the radiator (obviously). Don't use the LNA. The max RPM is 1500 and will be just fine compared to the stock fans. The H100i fan controller can only spin the fans up to 1400 rpm. Maybe its just my unit, but I think it will also be the same for you. The LNA won't connect to the pump unit. You must connect it to the split end if you do decide to use it. I am very happy with the noise of these fans. Even when benchmarking they are hardly noticeable at 1400rpm Link to comment Share on other sites More sharing options...
jrockz Posted March 8, 2014 Author Share Posted March 8, 2014 Ok good to know. I also have my noctuas touch the heatsink on my mobo because of space issues and also the fan power/cpu wire touching the heatsink as well. Should I be worried about the wire and fan getting melted?

I also have my noctuas touch the heatsink on my mobo because of space issues and also the fan power/cpu wire touching the heatsink as well. Should I be worried about the wire and fan getting melted? I have the exact same issue. I had to unplug the power cable from the board and bend it as far as it would go to fit the fans. The stock Corsair fans seem to have a contour that made them easier to install. What heatsink on the Mobo is it touching? Some do get very hot and may slightly melt the Noctua plastic but I wouldn't worry about it. Just run some Prime95 and keep an eye on it to make sure though. May want to cut a small piece from the fan. Mine get very close to the RAM but doesn't touch it. What is your case and mobo? Maybe post a pic of what/where/how its hitting. Edit: I see from your Specs what you have and don't know those parts well enough to say much but I'm sure there are others with that combo. I think I found the board and see there is a black heatsink that is higher than the RAM even. It doesn't look too high profile so it must be hitting the backside or something? You can actually touch the heatsink to see how hot it is. Just turn the machine off and ground yourself then touch it. "Hot to the touch" is 140F. Melting point of that plastic is probably pretty high. Link to comment Share on other sites More sharing options...
Doner1626864112 Posted March 9, 2014 Share Posted March 9, 2014 And I reread the OP and didn't see that you say the Corsair Link will only let the fans go to 980 RPM. I don't gave that problem. Mine go to 400 RPM. Maybe look at setting a custom curve. What is the H100i temp when they are spinning at 980? Did you try default or manually adjusting them?

jrockz Posted March 9, 2014 Author Share Posted March 9, 2014 I just set at silent setting, I dont really know how to use the custom curve. At 980rpm my cpu is running at 30-35degrees. Link to comment Share on other sites More sharing options...
