H100i Vs H115i: Which One Is Right For You?

The H100i and H115i are considered top-performing water coolers. And since both belong in the same series by the same manufacturer, they are a great deal alike.

H100i Vs H115i: Which One Is Right For You

To distinguish between the two, let’s go deeper into their similar and different features.


Similar to other CORSAIR liquid coolers, the H100i and H115i are easy to install in four easy steps. The whole process should take around fifteen minutes, or even ten if you have experience with PC.

Because the H100i and 115i are AIO (all-in-one) water coolers, they are significantly easier to put together compared to custom loops for which you would have to cut your tubes and pumps.

Moreover, both of these coolers are known to be reliable. They are secure, do not leak, and are guaranteed to last for at least five years.

CORSAIR iCUE software
Both the H100i and the H115i are compatible with the iCUE software. iCUE software acts as a management hub that helps you control and monitor temperature, RGB lights, RPM, voltages.

If your CPU gets hot, you can increase the fan speed or adjust things accordingly to maintaining a low temperature for your CPU. You also have the option to stop the fan entirely if the temperature is low.

The iCUE software is a big plus for these liquid coolers. Not only does it let you monitor cooling performance, but it also syncs up the RGB lights of all CORSAIR products. You get to customize the aesthetic of your PC however you like.


There are three significant differences between the H100i and the H115i.
Let’s go over them now!

Radiators are one of the essential features to look at when selecting your PC cooler. A radiator functions by cooling down the water inside the loop, which has absorbed heat from the CPU.

So how does this affect the cooler’s performance? To put it simply, the bigger the radiator, the more surface area you have to cool down the water.

The H100i has a 240mm radiator while the H115i has a 280mm radiator. Given the functioning principle we just discussed, the H115i does a better job of cooling down your CPU.

Fans Speed And Noise Level
Another significant feature is the fan’s speed, which directly correlates to the noise level of your cooler.
The H100i has two 120mm fans with a maximum speed of 2400 RPM, while the H115i has two 140mm fans with a maximum speed of 2000 RPM.

In terms of performance, the H100i has to spin faster to get the same amount of air as the H115i.

With a bigger fan size and lower RPM, the H115i can take in more air while spinning slower. Hence, the H115i is quieter than the H100i while doing a better job cooling your CPU.

Although not as expensive as a custom cooler, an AIO liquid cooler can still take a real chunk out of your bank account.

As of 2020, The H115i has a significantly higher price than that of the H100i, about 100 dollars more per unit.
Given all the fans and radiator upgrade as well as RGB light features, it might be worth it to get the H115i. However, if you have a tighter budget, and H100i will still do an excellent job at cooling your CPU.


H100i vs H115i, which one is better? The short answer is the H115i outperforms the H100i in cooling down your CPU while producing minimum noise. However, it is expensive, and you might need that money to upgrade other PC components.

Ultimately, both coolers are efficient and of high quality. Whichever one you chose, you will have an enhanced PC experience.

Good luck!
