I just bought a H115I RGB Platinum and can confirm I've come across this issue in stress testing my CPU.
The first time I noticed this it seemed like the temperature the cooler shows in its performance section was updating showing 40C but the fans were doing nothing.
second time temp and fans speeds both froze.
Of course this isn't helpful when I see my cpu temps creeping towards 90C on a stress test so I had to cancel that.
Both times was when I was using a custom profile. When I used the extreme profile it worked fine for about 1.5 hours until I switched back to custom and within ~15 minutes the freeze hit.
I had read riva tuner might effect so I've uninstalled that to test and closed MSI after burner (In eed the later though for my GPU custom fan profiles - I do nothing with my GPU in Icue so I would they aren't related).
Really hope this gets resolved as reviews for the cooler seems really positive but had I read about this issue I wouldn't have purchased and seeing how long it's been going is really concerning.
Update: Tried without MSI Afterburner, no change. Custom profile just plain doesn't work correctly.
It's strange because the graphic of my CPU block that has the lights on it will occasionally freeze and when that happens sometimes the shown temp drops to 10c (which is wrong since my cpu is over 90Cwhen icue bugs out). Other times the cpu temp stays fine but the fans randomly drop right to 400 rpm even though the temp is well above my custom profile.
Switched to extreme and it seems to work ok and keeps my temps under 90c again as it should. Customer profiles seem bugged to all hell.
If this can't be fixed can anyone confirm if the following solution would work:
Plug my pump into a system fan port on my m/b and the 2 cooler fans into CPU_fan and CPU_Opt.
I then use more stable software (if not bios) to set system fan to 100% so pump is always at 100% and then using more stable software that works correctly to create new curve profiles for CPU_FAn and CPU_OPT based on my CPU temperature (not as ideal as the cooler temp but at the moment what icue offers is pretty useless).
Olny other thing would be the RGB but I imagine I can just leave that hooked as normal along with Sata plug?
