Hello Ray and forum members,
I have 2 questions about the CLCP:
1) When SIV is not actively controlling the fans (during boot/shutdown), they ramp up to 100% - is this something that can be changed on the CLCP, or is it some kind of fail-safe hardcoded behaviour to prevent thermal issues?
2) I know I can update the CLCP firmware from SIV, but how do I actually get the firmware file without installing CL4/iPOO?

1) Mine don't and as you have failed to even post a [ Link Fans ] screen shot I can't even guess why.
2) Oh no it can't and you have to use iPOO. To do this I install iPOO on a sacrificial system.
3) I have the CLCP 0.9.212, do you know if there is a later release?

1) attached PH140 are factory default 140mm Phanteks case fans (3-pin) PH-F140MP are Phanteks 4-pin fans ML140 are 4-pin Corsairs "x2" specifies there are 2 fans on a splitter 2) oh dear 3) I installed iPOO, updated the CLCP and removed iPOO as per these instructions .. the latest firmware as of now is still 0.9.212 EDIT: it isn't actually 100% across the board, it's around 1200RPM for all the fans (which is the max for the Phanteks, but not for the Corsairs)Attachments:

As temperatures external to the CLCP are used to control the fan speeds SIV needs to keep writing these to the CLCP. I assume when it stops doing this the CLCP sets the fans to 100% to ensure things don't get too hot, but you need to confirm this with the CLCP specification, but as Corsair fail to publish this it's not possible to do this.
You could setup a different profile that uses CLCP temperatures to control the fan speeds and switch to this before you shutdown SIV/the system.

You are correct as usual - that's the root cause: when setting the only temp probe I have attached to the CLCP as the Feedback Temp, the fans no longer ramp up during shutdown and boot. Thanks, I will try to work around the issue now that I know how.

Hi Ray, finally managed to get back to this one: 1) I'm able to export the cooling profiles (and switch them with hotkeys), but it looks like the exported profile does not contain the feedback/control temperature: EDIT: after looking at the SIV registry keys I've found out how to add the feedback/control temperature to the profile file (and it works): 2) It would be great if SIV had a setting to switch the control temp to a desired one on shutdown, but I'm probably asking too much  Attachments:

1) thanks
2) understandable .. also, it wouldn't help - even when setting the control temp to the probe temp, the fans still ramp up when the PC is powered off. On restart, they stay quiet. But on shutdown+powerup they still spin up to ~1200RPM, so I'm at a loss here
