Guide: Fix Corsair H100i Not Detected in Corsair Link (Windows 8.1)

This is a bit of an odd one to write, and honestly it’s just for myself to remember if I ever wipe/reload this new system I just put together.

I did notice during my build that my Corsair H100i and AX1200i cooler/PSU were not being recognized at all in the Corsair Link application. After verifying the header was properly attached to the motherboard, I started poking around in Device Manager, trying to figure out which device it was. I found that two different devices will show up in Device Manager when the H100i is properly detected, and they both have the Hardware ID of ‘HID\VID_1B1C&PID_0C04&REV_0200‘. This is the key in fixing things.

Windows 8.1 employs an “enhanced power management” feature, which I remember from a while back with Microsoft Knowledge Base article. After some quick research it apperas that Windows 8.1 was trying to suspend/ignore the H100i since no software was accessing it.

A quick fix to this can be done in the registry.

  1. Hold Win and tap R.
  2. In the Run window, type in regedit.exe
  3. Browse to
    • CurrentControlSet
    • Enum
    • USB
    • VID_1B1C&PID_0C04
    • ###### (This will be random on each install)
      • You should only have one 1B1C item in Device Manager, if you have more than one, go through Device Manager and find which instance correlates to the H100i.
    • Device Paramters
  4. Change the following values to 0
    • AllowIdleIrpInD3
    • DeviceSelectiveSuspended
    • EnhancedPowerManagementEnabled
    • SelectiveSuspendEndabled
  5. Reboot
  6. Install/Launch Corsair Link.
  7. You should be almost immediately greeted by a firmware update (if your H100i is new out of box).
  8. Update if applicable
  9. Verify you can see your H100i and AXi (if present) in Corsiar Link

Hope this helps someone else searching.


  1. Excellent! Got it to work! Thanks :):)

    I know that the 1200AXi/H100i mix isn’t that huge in the world. Shoot, my H100i is only in place while the rest of my custom cooling gets in. But this is the answer and if you have this problem (which you probably will if you have both devices) this is how you quickly solve it. In fact, I had my H100i being recognized before I could even reboot. It also upgraded the firmware before I rebooted (I had Link running with the 1200AXi for a couple days before I decided to get the H100i). I chose to do the upgrade, which I regretted in my mind for a second right after I said OK, but it turned out fine. Then the reboot and Link now sees the 1200, the H100 and the rest of my system and fans like it always should have. Thanks Corey!

  3. Hi mine is not working well .

    -Rampage 4 Formula(latest CAP bios)
    -I7 3930K @ 4Ghz/1.35v
    -Dominator GT 2133Mhz 16GB 9-11-10-27-T2 1.5V(bios set to 1.520v to be allways at 1.503-1.520)

    -SSD OCZ Ve. 120Gb
    -HDD WD 1 T
    -Win 7 U 64bit

    H100i HATE THIS SHIT! Have it from 2013 and till now never get it to work fine .
    First ignored my saved profile , and worked only on H100i Temp after I updated to the last version 2.7.5361 now my H100i temp is( 0 ) my CPU Temp is 0 blinking red then after some time like 10 to 15 sec. it show up then starts all over again. It finaly save and use my profile but not geting temps right.

    Now I tried uninstalling deleting all folders even hidden then tried changing usb on MB and even deleted registry key’s rebooting and all the possible thing , but 0 result this shit is not working !!!
    In my registry the keys to set to 0 are only 3


    others have 4 or 5 why I got only 3 ? and mine gets installed stock set to 0 .

    Sooooo now wath ? hope Corsair is ready to refound 1 year and still no solution , btw why I payed 100€ and have to do all the work ? From wath I know selling malfunctioning stuff is NOT legal !

  4. This fixed my issue, too. Corey, you’re a legend!

  5. I can’t access the device parameter it said : “properties cannot be opened. an error is preventing this from being opened. detail access is denied.”

    how do i fix that?

  6. thanks for sharing but it didn’t work for me. running asrock x99m, intel 5820K, h100i. i’ve read this is common for amd cpu but i’m running intel. any other ideas?

  7. Thank you!

  8. just to give an update on my situation, i contacted corsair. they told me to use an older version of corsair link and it looks like it’s working in terms of temps and fan speed. the LED custom color works as well but the color is not accurate. for instance, i’d like it to be red. the software displays red but the LED is more maroon. i’ve given up and will probably no longer buy corsair water cooling.

  9. Dude you are the best let me ask you this. I had 2 instances of the 1b1c (04 and 06). I have the h100i and changed the parameters in 1b1cxxx04 and got the cooler to work. I also just got the hx850i psu do I have to do the same thing to get the psu to work but in the 1b1cxxx06 instance? Crazy question I know but you just helped me after 4 hours of searching!

    • Hey dude, sorry — I have an H100i and a AX1500i PSU as well. I did *not* have to change anything on the PSU side to get it to work, so I don’t recall changing the 1b1cxxx06 instance myself, but I may have on accident as I was trying SO many different things at first to get the H100i working properly!

    VID_1B1C&PID_0C04 is not present for me once USB is selected. The unit is brand new. Any suggestions would be greatly appreciated!

    You’re a champion! This worked for me.

  19. Thank you so very, very much !!!
    I had to re-install Windows 10 and after I did this, the H100i was no longer been detected, which is very strange.
    Your solution worked perfectly.
    I wish I could buy you a beer 🙂


  20. Thanks for this guide, it would appear this is still required in Windows 10, worked perfectly.

  21. Thanks a lot !

    No more problem with my H100i on Windows 10 full updated 2016/01/03

    Corsair Link can detect my H100i !!

  24. Пойми один момент. Завоевать женщину несложно. Это не такая уж большая проблема. Большинство на это способны. Почти каждый мужчина хоть раз в своей жизни завоевывал хотя бы одну женщину. Отношения начинаются с влюбленности: с осознания того, что другой человек занимает и будоражит твои мысли, с тяги к нему, с первых свиданий, робких поцелуев и трогательных признаний, с волны страсти, которая накрывает обоих. Потом они развиваются. Скука и монотонность повседневности постепенно выжигают страсть. Все исчезает. Вместо чувств появляется пустота, которая вскоре заполняется безразличием. Отношения либо прекращаются, либо становятся ненастоящими. Статичными. Мужчина и женщина начинают искать то, чего им теперь не хватает, в стороне друг от друга. Сохранить отношения и удержать женщину – вот, что сложно. За это всегда отвечает мужчина. Отношения спасает то же, что их и создает. Не секс и подарки. Дарить цветы и подарки по праздникам – не сюрприз и не показатель внимания. Это несложно. Чтобы сохранить отношения, мужчина должен уметь радовать без причин. Для чувств не нужны поводы. Женщины любят сюрпризы, подарки и цветы, так как это проявление к ним внимания. Они понимают, что о них думают и их ценят. Постоянное проявление внимания в нужной степени к женщине – вот на чем держатся отношения. Процесс этот обоюдный, но начинать его должен мужчина. Чтобы получать, нужно уметь отдавать. В женщинах мужчины часто не видят главного. Они видят их красивыми и сексуальными. Притягательными и опасными. Все это так, но если они посмотрят глубже, то увидят маленьких девочек. Внешняя красота – это напускное. Внутри мягкое и нежное. Там ребенок. С годами они не меняются внутри. В течение жизни в поведении становятся жестче, но все это только защита. Поняв это, ты поймешь, как сделать ее своей. Надо завоевать ее, как ребенка. Секрет прост. Внимание и забота о ней. Постоянное внимание. Мелочи. Такие, как – пожелать доброго утра, узнать, как она себя чувствует, кушала или голодна, оделась ли теплее в холодную погоду, выслушать и просто обнять. Умение решать ее проблемы. Стать тем, за кем она захочет спрятаться. Дать ощущение заботы и надежности. Такие мелочи в отношениях решают все. Из них возникает доверие. Женщины ценят это всегда. Вот весь секрет, он прост. ПРОСТОЙ СЕКРЕТ
