ICUE Link

[grundy1973]

Hi all.
Anyone else here experienced with ICU LINK?
My system runs fine and is almost silent, but the fans ramp up when the cpu warms up. Just for a few seconds then slow down again.
In the icue software all fans are set to balanced and the pump on silent.

Which cooler did you order?

I have a new H150i in my system, weather they're Links or other models I don't think affects the fan controls as they all basically run off the same in built defaults in iCue rather than set independently on the cooler.

I actually have the same issue. I just haven't gotten around to doing anything about it yet as it doesn't really bother me. I didn't have this issue on my old H100i from 2014, so it appears likely a "bug" perhaps in newer AIO's, I'm wondering if it's specific to the H150i's based on some other things.

How it SHOUD be is that the fans are clocking themselves based on the coolant temp, and not the CPU temp. This is how it should operate. The thermal mass transfer to the coolant is something that happens gradually, it's not instant like CPU temps are, so it SHOUD mean that fan increases are really gradual, but from what I've seen the default curves set in iCue mean that actually the coolant is always warmer than it needs to be which leads to this kind of behaviour.

There's a good article on the Corsair forums here with both a confirmation from a Corsair rep about coolant temp being the relevant metric, and also from an experienced user about setting custom fan profiles over using the defaults

Default Sensor AiO's in iCue.

Ok, to keep it as simple and short as possible. Since an half year, I am year a "proud" owner of the Capellix H100i but from the start I was wondering why this cooler, although performing, was overmastered by coolers like for example a Fuma 2. I even ordered the new AM4 retention kit, with my reg...

There's a guide on setting custom fan curves here: https://www.corsair.com/uk/en/explo...made by,your CPU cooler's coolant temperature.

The pump should not be on silent, and IIRC there is a set of default profiles for both fans and cooler (they're labelled differently than on the non iCUE Link items). Mine were set to track the CPU temp, which meant lots of up & down fans adjustments, so I set mine to track coolant temp instead.

But you may have to play with the fan profiles to get a balance of performance over noise levels that is suitable to your requirements.

I think your's is similar to mine, so I can get a screenshot of my profiles if you wish.

I have the H150i. And thank you both👍🏻

Note that the profiles are purposely different on the bottom, side and rear fans, as as I don't want the frequencies to match and create any extra noise.

Also, I can't say that at 35c coolant temp I can hear the 7 fans that are currently running (at 500-900rpm) and pump (at 2700rpm) over the fan in my external Thunderbolt enclosure...

So...

• AIO Pump is using the default 'iCUE LINK H150i LCD Balanced' profile
• AIO fans are using the default 'iCUE LINK H150i LCD Quiet' profile

Rear exhaust:

1. 20% at 30c
2. 30% at 35c
3. 37% at 38c
4. 46% at 40c
5. 55% at 42c
6. 65% at 44c
7. 85% at 46c

Bottom fans (this is where most of my intake air comes from, and is low flow from startup):

1. 30% at 30c
2. 50% at 40c
3. 55% at 41c
4. 60% at 42c
5. 65% at 43c
6. 70% at 44c
7. 75% at 45c

Side fans (rarely come on, and if they do it's at low speed):

1. 0% at 35c
2. 25% at 38c
3. 30% at 42c
4. 38% at 45c
5. 49% at 48c
6. 62% at 50c
7. 75% at 51c

Nice, thanks Tony
