So I got a Corsair H100i GTX in around November of 2015. I distinctly remember not liking it for the first few months because I could hear the pump. It didn't sound bad, it was just noisier than I expected.
Sometime middle of last year (2016) I noticed that I couldn't hear the pump anymore. I went to check the pump RPM, and couldn't find it. No program in Windows can see it, and it doesn't show up in the UEFI either.
I know for a fact it is actually pumping, because if I unplug it while the system is running it gets very hot very fast. I just don't think it is pumping at full speed. When I overclock and stress test the temps get hotter than I think they should.
So, someone with this cooler, I should see an RPM reading, right?
Just installed Corsair Link and it doesn't show anything. I might have to plug the cooler in using USB or something, not sure. Never used it.
I mean, the pump is plugged directly into a fan header on the motherboard. I also had it plugged into the dedicated pump header, and it didn't show anything there either. Both fans are also plugged directly into fan headers on the motherboard (CPU and OptCPU).
Check out the manual and see if you can plug the cooler into an USB port... I mean Corsair made that software specifically to work with those coolers and a bunch of power supplies... And many people over praise them, so there should be something...
So I plugged the USB cable in and the pump showed up in Corsair Link. I can even change its mode between 'Quiet' and 'Performance.'
Boggles my mind that they would put a three conductor, three pin connector on there for the pump, and not pass the RPM data to the motherboard header. The RPM wire must not be connected internally. It only reads the RPM through their proprietary USB protocol.
Hopefully it saves the mode setting between boots, because I am only using Windows for OC testing.
Not sure about that. It may easily save the profile in the software, in which case as soon as you turn off the software - the settings are gone. If it saves them on the actual AIO module somehow - then fine, but I doubt that...
The unit I took apart was an older style Corsair H60; fortunately, they sent me a replacement before my warranty had expired. The pump actually got louder, and sounded like air was trapped in the fins. I had to occasionally flick the tubes, which would sort out the noise, and temps would recover for about an hour(a 10c difference, at first). Replacement pump has been in operation for ~4yrs without issue.
That's pretty gnarly. I have an old H50 in a desktop still. Hope mine doesn't look like that.
My H100i GTX seems to be doing alright. After switching it to 'Performance' mode temps are much better. Can't really hear it, either. I am pretty sure the mode setting is internal to the pump itself somehow, because temps are very similar between Linux and Windows. So that's cool.
Just wish it was able to supply RPM data on the third pin.
