Is it possible that when using the pwm settings in the BIOS to control the H100 fans that it can cause Corsair link to mis behave when setting a custom curve?
 
The fans on the H100i are connected directly to the pump and controlled via the Corsair Link software.

Disable all fan control options in the BIOS relating to the CPU fan.
 
If you've connected the H100i fans to your motherboard and are trying to control them with the Link software then that will probably cause problems. If they're plugged into the pump then as far as I know the Link software takes priority over whatever fan settings are set in the bios.
 
I've got it now, thanks. It's so different compared to the conventional air cooler.

I have another question, does this look about right to you?

2500k is overclocked to 4.5ghz, 1.33v and +0.033 offset.

H100i profile is a custom fan curve:
  • 25deg - 0rpm
  • 28deg - 800rpm
  • 30deg - 800rpm
  • 45deg - 1200rpm
  • 50deg - 2100rpm

The above screenshot is showing Prime running along with CPU temps and on the bottom left, you can see the RPM for the H100i fans.

Now, the fans should be spinning quicker as per the custom fan curve, but since the temps are seriously low (compared to my K2) I'm not worried. I am however, wondering if I have missed anything.

Even playing BF3 and BF4, the RPM varies very little.
 
Your temps looks good, provided that your CPU is overclocked.

I think the reason why your H100i fan rpm is not revving up, is because you have those fans under H100i/coolant temp group and not CPU temp group. By default, both fans will be under H100i/coolant temp where the fan curve you set will vary on the coolant temp and not CPU temp. Technically, we do recommend it that way. Coolant is the agent that dissipate heat from the CPU, so it would only make sense if you have the fan curve based on the coolant temp rather than the CPU temp. Plus, CPU temp will fluctuate more frequent as oppose to the coolant temp which will be more linear and steady.

Thanks for that, I guess looking back it makes sense now. Yes, my 2500k is running at 4.5ghz at 1.33v. This is my fist AIO and I was not really sure how it worked and I was under the impression the fan curve used the CPU temp, not coolant.

I must say, I'm seriously impressed. It's made my system so much quieter, wish I'd gotten it sooner.

Thanks Greybeard.
 
Question:

When I move to the Parvum case, I'm going to keep using my H100i and get some Corsair SP120s to replace the stock fans.

If I was to use these in Push and BitFenix Spectra Pros in Pull, am I correct in thinking there would be no hindrance with performance? The Spectra's are only being used for aesthetics.
