Conclusions

The Corsair H45 is an interesting liquid cooling system. It is simple to install and inexpensive, being a good alternative to the heavy high-end air coolers.

The H45 surprised us regarding to its performance: it performed well compared to two of the best air coolers we tested so far, but also wasn’t bad compared to the best liquid cooling systems we included in this comparison.

On the other hand, the price it pays for such a cooling performance was the high noise level, caused by its high speed fan.

So, the Corsair H45 is a good entry-level watercooler, with good cost/performance ratio, if you don’t mind about a noisy PC.
