Corsair h80i GT along with new mobo/cpu, not reading fan speeds anymore?

post #1 of 7
Thread Starter 
I couldn't really see any other forums/sub-forums for this to belong too, so if this is the incorrect location for this? If a moderator could move it to the correct sub-forum, that would be great.

So essentially, what happened is this:

I bought a few new parts and set them up and the new parts that I bought were as follows:

  • ASUS Z79-K
  • Intel Core i7-4790k
  • Corsair H80i GT

I installed everything and everything seems fine, I loaded up my BIOS to make the standard changes (e.g. correct boot order, making sure the RAM latencies were fine and so on) and at first, I noticed that my fan speeds weren't being picked up, but I restarted after making the changes to my BIOS, I checked again and they were there and they were fine, so I thought nothing of it.

So I also recently built a friend a very similar PC to mine and he was asking me what temps I was getting on my new cooler and so on, he then informed me that he was getting 116c (maximum) temps on his motherboard on the HWMonitor program, so I thought this was very strange but apparently it's due to the fact that HWM is very bad for reading specific temperatures, so I thought I would try and see if a BIOS flash update would solve the problem (it didn't).

So after I installed the update, I went from v2404 to v2801 (the latest version).

I restarted and had to go back into my BIOS to make any kind of changes that were necessary, I then noticed that my fans were not being picked up by the BIOS in any way, shape or form. I loaded up my computer and checked Corsair Link and although everything else on my cooler was being picked up (the cpu temp, the pump speed) the fans were 'not'.

So finally, I went back into my BIOS, I put the fans on full speed and then and only then would the fan speed be picked up, but if I put it on it's default setting it will not be picked up what so ever and it's rather annoying and I would just like to get to the bottom of it as I don't like having issues w/ my PC, especially one such as this as it makes troubleshooting in the future near impossible.

Does anyone have any idea on what the issue could be? As everything else is working as intended.

Sorry about the wall of text.

I have a similar config and have had and continue to have similar issues. Here's what I've done to solve this and how I caused it :

But first... Corsair Link 4.0 just came out. I would recommend it. I doubt they're still working on bugs in 3.

I can re-create this problem consistently by unplugging the USB header cable and plugging it back in, even if the computer is off. I can also create this problem if my USB headphone driver fails, forcing me to reboot, so this is likely a USB problem.

Rebooting after wiggling the USB connector or disconnecting/reconnecting while the system is on and reinitializing Link fixes this problem every time for me.

Why are you controlling your fan speed from the BIOS if you're using LINK? I would suggest turning off fan management in the BIOS and leaving this up to LINK.

Also... 116°C?! As in, above boiling water temperatures? That can't be right.

Yeah apparently it's a HWMonitor issue and it's a misread, LOL.

So essentially, turn off fan monitoring in the Bios, fiddle around with the USB or maybe move it to a different USB connector entirely?

Yes and yes and definitely yes! A different header could be the solution. And don't forget to update to LINK 4.0. It can't hurt.

Will be doing that now and will report back once I've gone ahead and done this! (Already got 4.0 downloaded) Hopefully this will fix everything. Fingers crossed.

Unfortunately, it didn't work. Here is what I see in Corsair Link 4.0.



The mobo temp is obviously incorrect and if I look at that temp in my BIOS, it's around 28c, as proven here.



But i tried to put the USB connection into a different connector, it didn't work, I tried 3 different connectors, with no luck.

I have no idea how to fix this and it's really starting to bug me.

Sorry for the late reply. I had assumed someone else might chime in. Do you have photographs of your configuration?

I'm assuming... H80i > usb cable > USB 2.0 motherboard header
Are you using the stock fans that came with the GT and are they plugged into the PWM harness that comes with the GT?

Have you tried booting the system with the USB unplugged and the fans and pump running on fan headers (so you don't overheat), then shutting down, connecting to USB, and rebooting? That might reinitialize the USB device and produce readings.

Also, your motherboard USB configuration might be a factor. But save that for last.

Yeah 115C is odd... I wonder if your motherboard is reporting 115 Fahrenheit (46C), which is very reasonable for a Temp 3 sensor, which on my system is the CPU Package, but the software thinks it's in C. That's up to your board manufacturer and possibly a BIOS config but it could also be hard-coded. I don't know ASUS very well.
