Hi,
Whenever I play Battlefield 4, my CPU's core temperatures reach 80-89C.
I think to replace my cooler to Corsair H100i.

It probably is not running at 100%. Look on the motherboard. Near where the connector is plugged in, there is a label reading something like "SYSFAN1" or "CPUFAN1". Once you find out which one it is, go into bios (pressing DEL constantly on boot) and look for your fan settings. Change the fan header to run at 100% all of the time. Let me know if you need more help. The bios can be confusing. If you want more help, I will need your exact motherboard model and fan label.

OK.
My motherboard is Gigabyte Z97X-SLI, I think the label's name is "SYSFAN1".
Can you help me go through the steps to change the pump header voltage to 100%?
Thanks.

Okay follow these steps (this was found in your Motherboards manual),

Go into bios (pressing DEL on boot repeatedly),
Click on M.I.T. Tab,
Enter "PC Health Status",
Scroll down to "1st System Fan Speed Control" and press enter,
Scroll to "Full Speed" or "Manual" and press enter (if full speed skip next 2 steps),
Now select "Fan Speed Percentage" directly below "1st System Fan Speed Control" and press enter,
Set percentage to 100% (use +- keys maybe),
Press F10,
Select save and quit.

Test!

Let me know how it works. If full speed mode does not work try manual and 100%. Good luck

this cooler uses fan motor to run the pump so you need to make your fan speed speeds highier to run the pump at highier speeds

sorry for my english

Good point but a fan motor cannot control water control as far as I know. I still think what I stated needs to be done in order to get the system to function,
The manual states:
Note: make sure to disable the Q-Fan Control function of the connector in the BIOS

What can I do?
Thanks.
