MarcoHasAName Posted November 28, 2017 Share Posted November 28, 2017 (edited) Hi, I don't know if this has been posted before or if there is already an answer. So I have a i7 6700K, with the Corsair H80i v2 liquid cooler. I upgraded my motherboard to a MSI z270 gaming M7 (from a MSI z170 gaming m3) very recently and since then my Corsair Link always reads that the H80i v2 fan's sit at 0 rpm. I have read a lot of different websites and many posts suggesting fixing this in the BIOS. Since I know next to nothing about any BIOS, this is quite difficult. As well as my BIOS does have a clear "Disable fan" option. I am using MSI click BIOS 5. Can anyone help me, give me a run down on what I should be doing to fix this? Thank you.

MarcoHasAName Posted November 28, 2017 Author Share Posted November 28, 2017 "Yup.. pump is 600 rpm in bios head to hardware monitor.. and set cpu fan to Full Speed" If I did this, could I still use the fan presets in the app. Such as Quiet, Balanced or Performance? Won't that just make my fans sit on high forever, being very loud? Link to comment Share on other sites More sharing options...
DevBiker Posted November 28, 2017 Share Posted November 28, 2017 The fans speed on the CPU header that the H80i v2 is plugged in to doesn't control the unit. It provides power. Setting it to 100%/Full Speed ensures that the unit gets the full 12v that it needs. See http://forum.corsair.com/v3/showthread.php?t=168801.

snapper69 Posted November 28, 2017 Share Posted November 28, 2017 Is your cooler fan actually spinning? Where have you plugged it in? Link to comment Share on other sites More sharing options...
MarcoHasAName Posted November 28, 2017 Author Share Posted November 28, 2017 "Is your cooler fan actually spinning? Where have you plugged it in?" Yes, fan is plugged into CPU Fan 1, and is spinning. Link to comment Share on other sites More sharing options...
DevBiker Posted November 28, 2017 Share Posted November 28, 2017 The fan is plugged in to CPU_FAN?? Or the cooler? The H80i v2 has two fans that should be set in push/pull configuration. Link to comment Share on other sites More sharing options...

I only have one fan plug because the two fan plugs feel into a one plug adapter thing. But it is fixed now it is showing results, thank you!

Sheesh Posted December 30, 2017 Share Posted December 30, 2017 (edited) /bump Dev biker thanks again. I had the same problem. Setting the CPU fan header to full speed fixed my RPMs on both the fans and the pump. Dropped core temp from low 30's idle to mid-20's idle. Huge difference!!! So to be clear, the question of CPU header set to full speed in BIOS vs. high powered pump header on modern boards... which is best? I'd assume high powered pump header is best and has some advantages but I'm seeing a lot of conflicting opinions on the matter. Assuming HPW Pump header's only advantage is it frees up standard fan and CPU headers? Assuming you could you regroup the pump header with CPU and get the same benefits or something like that?

Assuming HPW Pump header's only advantage is it frees up standard fan and CPU headers? Assuming you could you regroup the pump header with CPU and get the same benefits or something like that? It is very board specific and tiny details may have more long term bearing on your preference. It seems most of these Asus boards have some quirks in regard to header behavior. MY CPU/OPT ignores the BIOS and AI Suite fan delays. On my X99 Strix, the HAMP header will always do a full 100% power on for PWM fans (unlike the other headers). This can be a minor annoyance and putting the pump on their would address the issue. However, that would then leave me in a bind with the rear fan and I would have three more or less useless AIO/CPU/OPT headers across the top. The HAMP header will work as a normal chassis fan header and the HAMP location may be more meaningful than most other things. As long as the pump gets its full 12v (for H80i v2 and H100i v2), it doesn't matter where it comes from. The other case building considerations will probably be the determining factor. You don't need the 3.0A capacity and those two coolers were made to run the standard 1.0A everyone else has. Trying to push that boundary while the fans are connected to the pump is more likely to short-circuit the cooler than the motherboard header.

Assuming HPW Pump header's only advantage is it frees up standard fan and CPU headers? Assuming you could you regroup the pump header with CPU and get the same benefits or something like that? Here's a dirty little secret: the AIO pump header, at least on the Asus boards, is just a normal, 1.0A fan header that's set to 12V/100% by default. That's it. And guess what? You can enable Q-Fan control for that header and use it just like any other fan header. So what's best, IMHO? Having a dedicated SATA connection for the pump. No silly 1.0A limitation, guaranteed 12V and available 5V and 3.3V rails if you need them. Link to comment Share on other sites More sharing options...

captaindust Posted January 11, 2018 Share Posted January 11, 2018 (edited) So eh i recently got a new pc and everything was working fine, but after a week corsair link showed 0rpm for my h80i v2 , i tried other driver versions and i tried disabling smart fan control in bios. But if i disable that and the pump gets full 12v then it starts spinning and pumping at full power and it will just stay at 100% all the time. I have no idea what to do now or how to fix this since i have a pre-built pc and know nothing about installing parts. see picture : windows also just gave an error message saying it doesn't recognize the usb device (bottom one) while the usbxp driver is there http://prntscr.com/hyy71t (specs: x299 sli plus mobo, gtx1070ti, i7 7740x and h80i v2 plus) any idea how to fix this? since it just randomly occured EDIT: when i clicked on devices in corsair link it recognized by h80i v2 BUT it says firmware version n/a EDIT 2: in device manager the CORSAIR USBxp keeps popping up and vanishing and there is also a "unknown usb device (failed to find adress)" (translated from dutch) Edited January 11, 2018 by captaindust Link to comment Share on other sites More sharing options...
DevBiker Posted January 11, 2018 Share Posted January 11, 2018 If the pump gets the full 12V, it will operate properly. If it doesn't, it won't operate properly and very well may fail in a short period of time. As long as the fans are connected to the pump, the pump will control the fan speeds. It won't have anything to do with the setting on the fan header; that is only there to give the pump power, not to control the fan speed or anything else. You will use Link to set and control your fan speeds. But you are seeing 0 RPM and the "unknown USB device messages" because the pump doesn't have the correct amount of power. So set it to 100% in the BIOS. That is the only fix. Link to comment Share on other sites More sharing options...

I stumbled upon this thread where you say to put cpufans on 100% so to get the 12v power the pump needs. When I do this in bios I just get fans and pump on full speed, but still neither icue or corsair link find my pump. My new hardware : I7-9700k Msi z390 carbon ac. Trident 3200 MHz ram Corsair hydro h80i V2 cooler The pump is connected to to CPU fan on MB and on USB header 2. I've also tried the other ones(3 to 5 USB headers) I've tried older versions of both programs. No dice. Any help/tips would be greatly appreciated.

c-attack Posted December 30, 2019 Share Posted December 30, 2019 If the entire device (H80i v2) is missing from iCUE/Link, then it is a USB issue. Try a different internal port. If the H80i v2 shows up in iCUE, but the pump speed is 0 rpm or below the 1800 rpm minimum, then you may have cut the voltage below 12v. Link to comment Share on other sites More sharing options...
Soyyojuli Posted December 30, 2019 Share Posted December 30, 2019 lk in my post i've tried them all. I just dont get any signal from the pump. Also the USBXp Driver isnt showing in device manager. Im really at a loss. I can only controll the fan speed in bios (its updated). Link to comment Share on other sites More sharing options...
tkahn Posted May 19, 2020 Share Posted May 19, 2020 I had this problem with my H80i. It showed 0 RPM most of the time even though the fans where running. I say most of the time beacuse occasionally the real RPM would flash by for a second in iCUE and then revert back to zero. I solved this by going into BIOS, disabling Q-Fan Control for all fans for my ASUS motherboard. After the reboot the H80i displayed the correct RPM for the fans in iCUE.
