Corsair Hydro Series H75 Installation Guide

By Dustin Sklavos, on October 25, 2013

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.

1

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.
