Corsair Hydro Series H75 Installation Guide


Installing the Corsair Hydro Series H75 CPU cooler can seem fairly daunting, but in this blog post we’ll have you up and running in no time flat. You’ll just need a single medium-sized Phillips head screwdriver.

With the H75, we’ve made installing cooling easier than it’s ever been. You’ll want to first remove the exhaust fan from your case; the H75 uses two 120mm fans and a 120mm radiator to ensure compatibility with as many cases as possible. For the purposes of this guide, we’ll be installing the H75 as an exhaust; this results in ever so slightly higher CPU temperatures, but lower overall system temperatures.


First, you’ll want to install one of the fans to the radiator itself. The interior side of the radiator is the one that has the hoses coming out of it; use the long screws to secure one of the two fans to the four mounting holes in the radiator at each of the corners with the exhaust side of the fan facing the radiator, making sure to place a washer on each screw between the head and the fan. You can tell which side of the fan is the exhaust by the four struts.


Next, sandwich the second fan between the case and the side of the radiator that doesn’t have a fan mounted yet and use the long screws (with washers between the head and the case surface) to secure everything in place. You’ll want the exhaust side of the fan to be facing the rear of the case so that air flows in a straight line through the two fans.

Now remove the plastic cap from the waterblock. There’s already thermal interface material on it so you don’t need to add any, but make sure that the material doesn’t touch anything but the top of the CPU, as it can be a nuisance to clean off.

The next part depends on the socket you’re using.


If your system uses Intel’s Socket 1150, 1155, or 1156, press the included backplate to the rear of the motherboard, pushing the four standoffs through the mounting holes in the motherboard. Next, use the four LGA1150/1155/1156 screws and install them one at a time into the standoffs, holding the backplate in place. Put the opposite ends of those screws through the four holes in the mounting ring around the waterblock, then use the thumbscrews to mount the block in place.


If your system uses Intel’s Socket 2011, you don’t need to worry about using the backplate. Simply install the four LGA2011 screws into the four corner standoffs of the CPU socket, then put the opposite ends of those screws through the holes in the waterblock’s mounting ring, then use thumbscrews to mount the block in place.

If your system uses any modern AMD socket (AM2, AM3, AM3+, FM1, FM2, FM2+), you’ll want to consult the included instruction manual for more detailed instructions.

The last step is connecting the pump and the two fans. The 3-pin connector extending from the waterblock can be connected to any non-CPU fan header on your motherboard. For the fans, you’ll want to connect the included Y-cable to each of those fans, and then connect the opposite end to the CPU fan header on your motherboard.

    Hello, would the Carbide 600Q (CC-9011080-WW) be able to control an exterior fan for the enclosing cabinet? I am looking at AC infinity fan controller but wondering if there is an additional fan port that could be used. Thanks, Rick

    I was wondering if this cooler is compatible with an am3+ socket. The Newegg spec discription doesn't specify am3+, but does state it is compatible with am3 sockets.

    I need to install the radiator in horizontal position, what pipe must be in the bottom? (suctioning from the radiator)

    This is a great product but it took a tad more time for me to install than in the video. I would say 30 minutes but I had to remove a top fan so The H75 would fit in my Haf 912 case. I am also 67 and installed this on the floor. I don't have a workbench. I would recommend this product to everyone. It is extremely quiet. Great work Corsair!

    I installed the H75 to my FX-8350. When I boot into bios, i watch as the cpu temperature goes up over a span of thirty seconds or so, and than the system automatically shuts off at 90 degrees celsius. How can I troubleshoot the H75. I think that is what the problem is
