I have a Corsair H100i as my water cooler on my 3930k and it works great.. but for one thing.  I have to wait about 8 minutes after boot up for the pump RPM to hit 2200RPM.   It sits at 500RPM while I wait.   And with this aggressive overclock, I can't do anything at all until the fan kicks on.   I have done searches on Corsair's forums but can't seem to find this exact problem.   Everyone is complaining about the Corsair LINK software not letting them control the fan speed but I dont need fan crontrol.  I need fan to spin fast right off the bat.   This fan speed loss happens while sitting in the BIOS menu as well.     After about 8 minutes though the cooler makes a sound like it's spinning down but the RPM goes up.   While it's 500 rpm it's noisy as all hell but when it goes to 2200RPM it's quite???  Does that make any sense?   It's kind of annoying having to wait 8 minutes before I can do anything on my PC.   Any thoughts?

Is this with every boot? I have the H100i myself, and once in a while it will make a strange noise and fail to spin up to it's RPM setting. What you're experiencing sounds more like the quiet or balanced profile is loaded and it just waits for the temperature to rise to spin up to 2200rpm.

 

Did you check what setting is active in the LINK software?

Have you tried to set fan speeds in BIOS? I would guess that your ASUS BIOS should enable you to manually set the fan speeds.

I can't install the Link software.    When I run the installer I get a BSOD and it reboots.    Nothing else does this.   I don't think it likes ASUS Suite 2

I looked but did not see anyway to manipulate the water cooler in there.   I turned of the Q-Fan controls in hops of forcing all fans to run max but that didn't seem to help the cooler RPM.

I have the H100i and can't say I have this issue, also I have corsair link sofware running fine. Do you have the the pump connected to the correct CPU fan header on the motherboard?

 

Also do you have the pump connected to the motherboard VIA a USB2 header (required for Corsair LINK support). The BSOD while trying to run the Corsair LINK setup is strange. I would try downloading the latest version from their website and running it again.

 

EDIT: From looking at your first post you noted that the pump RPM was at 500 then spooled up to 2000. You said you cannot get Corsair LINK to work properly, which is what I used to monitor the pump and fan RPMs. Can I ask what you were using to monitor the pump RPM.

I don't know nothing about the H100i system. I have the CM Seidon 120XL liquid cooler and have the pump connected to the chassies fan 1 power connector and the radiator fans connected to the CPU fan connector. When the CPU heats up, the radiator fans will spool up.

That's what I'm thinking too. Most motherboard fan headers are temperature controlled. You should be able to turn this feature off in BIOS. However, if you do want the fan at full speed all the time, maybe hook it up to straight to a 12V connector of your PSU using an adapter?
