how to connect 3 pin cpu cooler to 4 pin on motherboard

[andralika]

my cpu cooler: corsair h115i
motherboard:asus h170 pro gaming lga 115i
is it compatible?

Yes it is just insert it in the 4pin one where it fit one pin from one side will be left blank so no worry

Yes. The extra 4th pin is only a PWN signal (so you can use a program and adjust the RPM)

Just plug it in. It will do its job. But for your info, its job does NOT include having the mobo CPU_FAN header control the H115i system. All that connection to the CPU_FAN header does it allow that H115i system to report a speed to the header. That is important because most mobos pay special attention to the fan speed of the CPU cooler to detect possible fan failure. If the header gets no speed signal, the mobo may take drastic action to shut down your system, or at least issue a prominent warning for you to shut down before the CPU is damaged by overheating. So it is important to give that header a valid speed signal to avoid such drastic messages.

Actual CONTROL of the pump and the radiator fans of the H115i system is done instead by that system itself, using the Corsair Link software utility. You REALLY should have that downloaded and installed on your system. And it MUST have that cable from the H115i's pump unit to a mobo uSB2 header so LINK can communicate with the pump unit.

but the mobo cannot check the rpm speed is it okay?

Link is a software utility that you must download for free from the Corsair website for these cooling systems. If you have all of the connections made for the H115i system as instructed, just download that and install it. It will do its control job AND give you many tools to observe aspects of your entire cooling system and customize its control functions.
