How to Install the Hydro Series H100i GTX Liquid Cooler

 

The Hydro Series H100i GTX cooler is the latest version of our best-selling H100i, improving upon its predecessor in almost every way. While the 240mm radiator mounting it requires was less common when the original H100 launched, support for 240mm coolers is becoming ubiquitous in mainstream cases.

This guide is geared towards showing you how to install the H100i GTX on your Intel LGA115X processor. If you prefer video instructions, you can watch our guide on YouTube here:

Let’s get started!

Step 1: Mount the Backplate

First, adjust the notches on the backplate inward for LGA115X compatibility.

Push the standoffs through the back of the motherboard.

Next, use the silver standoff screws and insert them into the backplate. The backplate may be a little bit loose even with all four screws installed; this is normal.

Step 2: Attach Fans to Radiator

We’ll need to prep the radiator for installation inside your case.

Using the long screws included with the H100i GTX, attach both fans to the radiator, orienting the fan struts to the inside. You’ll always be able to tell which direction a fan blows by which side of the fan has the struts; we’re orienting these fans to push air through the radiator and exhaust that hot air outside of the case.

Step 3: Attach Radiator to Case

Gently slide the H100i GTX into the top of your case (or wherever the available 240mm mount is).

Use the short screws and washers included with the cooler to affix it to the case. It may also be easier to install the center screws first.

With all eight screws installed, the H00i GTX should now be securely mounted to the interior of your case.

Step 4: Mount the Cooling Block

The first thing we need to do before mounting the cooling block is remove the protective plastic cover.

Note that there’s a silver disc of thermal interface material already applied to the underside of the block.

Slide the block onto the standoffs.

Use the included thumbscrews to secure the block, alternating corners in the same fashion you would remove or replace lugnuts on a tire. Be careful not to over-torque the screws; you can use a screwdriver, but “finger-tight” is typically enough.

Step 5: Connect Fan and Pump Power Cables

Now that we have the H100i GTX physically mounted and the waterblock in place, we need to connect the cables that allow it to run.

Connect the leads from the two fans to the waterblock’s fan headers.

Connect the block pump to the CPU_FAN header on your motherboard.

Step 6: Connect Corsair Link Data Cable

While the H100i GTX can operate without the Corsair Link software, it’s needed to get the most out of your new cooler. The Corsair Link software allows you to change the color of the pump cap backlight, adjust the pump speed, and program your own fan curves.

Connect the mini-USB side of the included data cable to the waterblock.

Connect the USB header side to a free 9-pin USB 2.0 header on your motherboard.

When in Windows, visit the download site here to download the Corsair Link dashboard software to control the cooler.

Your new H100i GTX should now be fully operational!

Optional Extra Step

While the H100i GTX is designed to be as easy to use as possible, you may need to disable fan control on the CPU_FAN header in your motherboard’s BIOS. Consult your motherboard’s user manual for information on how.

    My CPU is also heating up to much if I try to game, and my bacplate does seem to be slightly loose. Could you please tell mew here exactly you placed the rubber washers to fill the gap? Was it between the backplate and the motherboard?

    The overheating issue is related to the backplate not being fully secured against the motherboard using the provided mounting hardware. I was told this is due to thinner style motherboards, as to why they haven't come up with the correct hardware is besides me. I also damaged my CPU not knowing why it was overheating and letting it run too long, luckily Amazon advanced replaced it for free for me. I do really like Corsair and this cooler specifically so I decided to install rubber washers that I found on Amazon (or any local hardware store) to help fill the gap and force the water-cooler tightly onto the CPU. This looseness is what causes a poor seal between the two and overheating issues.

    I made a mini gaming PC with mostly corsair products (not processor and mobo or main storage) it all runs great and I have nothing but good things to say about it. However, I'm hoping there are some drivers for the H100iGGTX cooler or something similar.

    Oh man, I'm having the same problem as Alan, did you get it resolved? When I tried to install my h100i v2, there was so much room between the backplate and cpu. I read that this is really bad, since it doesn't seal.. Is it supposed to wobble a little? Because that seems like really poor design if so.. Anyone have any advice to make it seal better? Or is it sealed better? Help pls. :'(

    So I have the corsair 600c and I need to install the h100i v2 in it, I am wondering which way do I have the fans set up? Do I set it to push air out of the case through the radiator or pull in from the radiator and blow air in the case?

    Hey, I just built a new pc, and I bought the h100i v2. When I booted up the system, the cpu temperature was over 75 degrees, at idle. Im not sure if I received a defective cooler or I installed it wrong. All the fans are working, and the led's light up. Please Help!

    I just purchased an H115i for installing on an ASUS Z170 TUF Sabertooth LGA1151 socketed motherboard. I notice that when I screw down the standoff screws to the backplate standoffs, there is a gap of several millmeters, so the backplate is loose. When I unscrewed the standoff screws and just looked at the backplate standoffs holding the plate against the back, the standoffs on the plate are several millimeters above the motherboard which is why it is loose (i.e. the standoff screws bottom out on the standoff so they don't hold the plate tight to the motherboard. Is this normal and/or OK? I've seen some blog posts that this is an issue in that the cooler may not seat properly without washers. The description above says that it is OK for it to be a "bit loose", but on my motherboard, I'd call it "very loose". Should I be concerned? Thanks, Alan

    I think the fans should be used as exhaust while installed at the top of the case. The fans should be intake if the cooler is installed at the front of the case. Just my $.02, as heat rises......

    The fan direction you show is exhaust, yet the Corsair manual says its optimal to set the fans for intake. Why are you doing it counter to the optimal setup?

    The driver for the H100i GTX is not excepted by Microsoft it is not digitally sighed. You should pay for all your platforms if your going to market a device or you can produce this device and defraud the consumer. I will return your product because it dos not function as described

    Does the AMD install need a backplate, or do I need to use the backplate that comes with my Motherboard (also could i use my 212 Evo's backplate).
