mitkinkerman Posted March 1, 2017 Share Posted March 1, 2017 Recently I bought 2 new Noctua NF-A14 140mm fans as a replacement for the default h110i fans but when I connect the two fans into h110i,only one of them are working,the other one doesn't spin and can't be read from Corsair Link.So I decided to put back my default corsair fans and they work flawlessly,please help?

red-ray Posted March 1, 2017 Share Posted March 1, 2017 The should work and did in http://forum.corsair.com/forums/showthread.php?p=875594 Maybe one of the NF-A14s is faulty. Do they work when you connect them to a PWM motherboard fan header? Link to comment Share on other sites More sharing options...

No,both of the Noctua fans work flawlessly when I connect them to fan headers on my motherboard,it just doesn't work with h110i's 2 4-pin headers Link to comment Share on other sites More sharing options...
snapper69 Posted March 2, 2017 Share Posted March 2, 2017 Do they work if you plug them in one at a time, i.e. just plug fan 1 into header 1 then just plug fan 2 into header 2 of the H110i cable? How does it get power? Is it via the motherboard header, in which case is it set for full power in the Bios or via a Sata cable? If it's a Sata cable is it plugged in properly, or can you try a different SATA cable? Link to comment Share on other sites More sharing options...
red-ray Posted March 2, 2017 Share Posted March 2, 2017 How does it get power? Like all CoolIT based coolers the CoolIT H110i get's it's power from a SATA power connector Link to comment Share on other sites More sharing options...

The only way I know to easily find out is to run my SIV utility and check what the mode is. Link to comment Share on other sites More sharing options...
