Hello,

I just got done putting together a new WC'ing setup. I have 2 rads and 4 fans hooked up to the CPU fan header. The fans are all from Koolance and DC controlled. All with a .2 amp rating. So no more than .8 amps are on the Cpu header. All my fans work in BIOS, but as soon as windows starts (before password screen) the fans shut off completely. ALL of my fans. I just calibrated them using the Q-fan calibration in BIOS. IDK what to do..... HELP

It would be much better if you bought a fan controller for powering up your radiator fans and controlling the speed of them.

All the fan headers shut off when windows starts except the 2 fan headers by the 24 pin PSU connector... I think my MOBO or windows is fried... I just tried uninstalling corsair link, because I thought it was the problem...

Also off the subject. The first 3 weeks I owned this board the 3000mhz XMP profile worked flawlessly. Now it only recognizes 3/ 4 channels. Sometimes B, C, D and sometimes A, B, D. I am seriously starting to think that something is wrong with it. I also just got a brand new CPU today and It acts just like the one before it. It wont get stable at 4.4ghz no matter how hard I try. It's also a Costa Rica chip if that makes a difference. Its funny brcause I have to do the same exact thing to this CPU as I did to the last 2 to get stable......

OK I attached 2 PWM fans from my former Corsair H100i to CPU fan and CPU OPT fan. Then I attached the 4 koolance fans with a splitter to CHA_FAN 3B and now it seems to work. Here Is Screen shot

I'll share some experience I have had with this stuff (but I've never build a custom WC loop).

1. I have fried MOBO fan headers before (on my Rampage 3 extreme). Plugging in 2 x high amp fans via a Y-cable to a single 3 or 4 pin mobo header can torch it. Thankfully it didnt wreck anything else on the board.

2. I have fried the fan control "part" of an H80i as well. The h80i (like the 100i) has 2 x plugs in the CPU block for fans. Well, as far as I can tell, they are meant for 4 fans max, 2 on each. One time I wrecked it by plugg in 4 x fans via Y-cables into a single channel on the H80i. That ruined that too.

3. Asus Fan Xpert isn't perfect. Sometimes my PC starts with the fans going 100% and I have to manually click the "silent" profile and then re-load my custom one. Happens a lot actually. I did the fan test from within windows. Might try it from inside BIOS, didnt even realize there was a fan calibration option in there until your post.
