Corsair Hydro H80 and H100
The obvious difference between the H80 cooler and the H100 is the radiator; the former has a 120mm rad, whereas the latter has a 240mm rad. Notice the difference between the thickness; the H80 has an extra-thick rad, while the H100 has a slimline rad. While surface fin area certainly helps improve heat dissipation, it’s been our experience that thicker rads typically perform very well when using the smaller size.
Here’s the H80:
And the H100:
Each of the units have a copper coldplate that’s directly integrated into the pump unit. This cuts down on separate component parts, keeping things very streamlined in terms of minimal space required inside your case, not to mention there’s less maintenance issues to be concerned with as well. Both the H80 and H100 come with Corsair’s pre-applied thermal paste. As we removed the pre-applied thermal paste to check the cold plate surface, we found it’s planed flat but not mirror polished as we often see on high-end CPU water blocks.
Since the radiator is thicker with its dual fan configuration, the H80 extends further outward and would interfere with the pump/block unit. Consequently, a low profile pump is a smart design choice, particularly for the H80. The stiff corrgurated plastic tubing is used in conjunction with the 90° swivel connectors at the pump, and this also helps make installing the unit much easier. The radiator connectors are fixed with 1/4" barbs and appear to be heat-sealed to the tubing.
Shown below is the Corsair Link that requires a special USB cable, which is unfortunately not included.
There’s a bonus feature here that we really like, as the fan control header will allow up to four fans to be connected.
As for installation, it was very straightforward. The H80 is extremely easy to install, while the H100 requires a bit more effort, but nothing difficult, though you do need a case that will support a 240mm radiator in an internal setup. The whole process isn’t much different than an air cooler, complete with backplate (for Intel setups), with the exception of mounting the rad/fan to an exhaust port. Thankfully we didn’t experience any issues with the corrugated hoses, so no worries about kinks if you take your time.
As you can see below. the H100 is particularly low profile and barely visible.
The Corsair pump and heatsink, along with the provided retention bracket mounted to the 990FX was a piece of cake as it did not require a backplate as it uses the existing motherboard mounts. The pump/block is secured by two thumbscrews and a locking key that was simple but effective, giving a solid and secure mount to the processor.
Let’s move onto the testing.
