Hi guys So yesterday I got 2x Notua's NF-A14 PWM. It's the first time I have PWM fans and I can't get them to work like I want. I tried to configure them with the MB Q-fan controller but it doesn't offer the flexibility that i want ( minimum rpm to high, and with medium temps to much rpm ) . I've just installed SpeedFan but it doesn't even detect any fan in my system at all, even after I tuned off Q-fan control in the BIOS. What do you guys think it's the best way to control case fans ? My system: Asus Maximus Hero VI / 4670k / Corsair TX650V2 / GTX770DC2 Cheers Everyone
First off, check in your owner's manual and make sure you actually have the fan plugged into a pwm fan header. The reason I mention this is that some Asus boards (like mine) actually have a 4 pin fan header that is not a PWM header - the 4th pin is... extra? The 4pin main CPU header should definitely be pwm ready. Setting up speedfan can be a bit tricky, I'll have to look at how I have mine set up when I get home before I can walk you through anything. Before you try to get it to do anything automatically, just try to figure out which fan label in speedfan equals which fan header and see if you can get the fans to change speed manually.
Hi automaticman I've just found out that speed fan does not work with z87 I'll be testing Asus AI Suite III, with fan expert 2 Thanks for trying to help anyway
I forgot that I ended up connecting my fans to the controller on the case and using AI suite to control the CPU and exhaust fan. The nice thing about AI suite is that you know all of the fan headers are labeled right, and you don't have to fool around with setup like with speedfan. I saw a close-up photo of the Hero and there are quite a few 4 pin headers, hopefully they are all pwm and controllable by AI suite. The one thing I needed speedfan for was to vary case fan speed based on gpu temp instead of cpu temp.
Well, the Hero sure has lot's of 4 pin header's, but they are all sort of fake, because the 3 chassis header's don't support pwm, only the 2 header's for the cpu fan's support ( you can read about this Here ). I sorted this out by connecting the cpu fan to one header and then used a Y splitter cable to connect both PWM's fan's to the other one. Now my problem is that i just can´t install AI Suite III on my pc , i download the latest version from asus website and when I run the setup nothing happens, I can only see a process running in task mananger but it's just there stuck... I'll try to install it from the CD that came with the MB, but I'll have to borrow a DVD Drive from a friend ( because i don't have one in my pc XD )
Yeah, this is what i was afraid of, and it's the same with the 4pin chassis header on my board. I have no idea what the point of a 4pin header that does not support PWM or what the 4th pin does. The other odd thing was that the two chassis headers supported voltage based fan control (with the two headers slaved together), but the CPU headers did not. I ended up connecting my CPU fan and chassis exhaust fan to the voltage controlled chassis header and used AI suite to set the speed based on CPU temp. Not sure why you would not be able to install AI Suite, though. Have you tried running it with admin rights? Have you checked in you UEFI screens to see if there is a FanExpert screen that gives you the same sort of fan control? You might not need AI Suite at all if it is there, you just won't be able to tweak it inside of windows,
