The flexible, powerful 120mm liquid CPU cooling system for high performance PCs
The Hydro Series H80i v2 is a high performance, all-in-one liquid CPU cooler that works with standard 120mm radiator mounts. The extra-thick 49mm x 120mm radiator and dual SP120L PWM fans provide the excellent heat dissipation you need for high performance CPUs. It’s Corsair Link compatible, so you can customize cooling performance, monitor system temperature, and change the color of the RGB LED lighting.
The 120mm radiator works with standard 120mm fan mounts for wide compatibility, but has a depth of 49mm for increased cooling surface area and faster, more efficient cooling.
Customized cooling performance
You can select the speed of the dual SP120L PWM fans via the Corsair Link control panel or any standard fan speed utility. And, you have options: use just one fan to save space, or install both in a push-pull configuration for extra cooling efficiency.
Built-in Corsair Link
Attach the included Corsair Link cable to a USB header on your motherboard and download the free Corsair Link software to unlock even more power.
You can customize cooling performance, monitor coolant and CPU temperatures, and change the color of the RGB LED lighting from the default white to match your system or to change color based on temperature readings and other inputs.
High-performance CPU cooling made simple
The H80i v2 is a closed loop design that comes pre-filled. It includes a modular, tool-free mounting bracket for faster installation, and it features improved coldplate and pump designs for highly tuned efficiency.

Now, the flaw, and it’s not insignificant.... check your motherboard for capacitors that are inside that box created by the heat sink support holes. If you have any capacitors inside that area, and a LOT of MBs do, these coolers WILL NOT mount correctly without modification.
They will SEEM fine, but if you look at the core temps on the side of the processor where the capacitors are you will notice that those cores run hotter by 10c or more.
Now, this flaw is fixable if you’re a semi-competent PC builder all you need to do is sand about .01” off the edge that overhangs the capacitors. It’s such a tiny interference it’s ridiculous but it’s there, and if you’re having overheating problems with these Corsair products, this is why.
You'll definitely want to enter your BIOS and modify how fast the air intake fan runs based on your CPU temps. Test how hot your CPU gets (not your CPU core temperatures), and set your fan to run at 100% power when your CPU reaches that temperature.
For example, my processor roughly tops out at 55C, so I set my fan to run at 100% power when it reaches that point to keep my core temperatures down by an extra few Celsius.
Thats not even the bad part, that's simple stuff to fix, the real problem with this is the redesigned CPU block mount... in theory i can see being able to twist it off easily being handy, but in practice it will pop off with the tiniest amount of torque... you CANNOT fasten this down tightly where it would stay securely, it's too easy to twist off, what if you were transporting this and it fell off... well thats yet ANOTHER problem...
Because... you see... when you go to put it back on... in theory, you could just twist it on... that would be cool... if it worked.... but it doesn't... you will have to unscrew the whole thing and hold it all together while you remount it.... nullifying any point in having the twist/removal system in the first place.... the metal is so flimsy that it bends downward towards the socket... try as you may... it won't slide back into the slots... i wasted a good 10 minutes on that before disassembling the whole thing
Ok, so even with all of those problems... I suppose I could have lived with it... it's a hassle, but it's keeping my CPU cool right? WRONG... heat levels are way higher than the older H75 units (I am testing with OCCT, and two identical Intel 4790k CPUs, nearly identical setups aside from the older/newer H75 units...
So... yeah I kinda want my $90 back... and send a message to Corsair that this design sucks, the older models are better... not sure why they tried to fix something that wasn't broken.... but they sure broke it...
