Corsair Nautilus 500 Water Cooling System

The Corsair Nautilus 500 is a very well-built external watercooling kit. That's evidenced by its ease of installation. Corsair claims that it can be installed in under 10 minutes. To be honest, we didn't actually time the installation, but it really didn't take very long to get it up and running.

Design-wise, Corsair really did a great job with the the Nautilus 500. It utilizes a very reliable and high-performance pump with a high-quality waterblock. Combine that with the ease of installation, this makes it a very good entry-level kit.

As far as the mounting is concerned, we would really like to know how Corsair can make do with only the stock mounting bracket. It's nice, of course, as it avoids having to remove the motherboard in order to install the waterblock.

Unfortunately, the waterblock doesn't seem to be mounted as securely as we would have liked. We were able to "wiggle" it a little, even with the bracket fully fastened. We also felt that the tubing was somewhat stiff, compared to other types of tubing in the market. But that's just a minor complaint.

Overall, the Nautilus 500 is a very well-built. It certainly didn't feel cheap. But we wonder why they decided to go with an aluminium radiator, as opposed to a full copper radiator. Not only will a copper radiator improve its performance, it would also avoid galvanic corrosion and do away with the need for additives like ethylene glycol.

Even though it's an entry-level kit, its performance is certainly commendable. It bested all of the heatsinks that we tested it against. Note that most of these heatsinks are no slouches! Two of them are actually the best in the market.

Now, Corsair states that the Nautilus 500 is "whisper-quiet". However, we feel that it's not really that quiet. The fan, on the "high speed " setting, emits a noticeable amount of noise. We believe that the noise itself isn't really from the fan but from the air moving through the unit.

Also, while Corsair claims that the Nautilus 500 is capable of dissipating 500 watts of heat, we have no doubt that it can. But we do not believe that it will be able to do so while maintaining the same level of performance we saw earlier. Not on a single 120 mm radiator, and an aluminum one at that.

Still, we enjoyed using the Corsair Nautilus 500. We feel that it's a great kit for the budding watercooling enthusiast, as well as those who don't have cases large enough to accomodate big watercooling setups.

The Nautilus 500 comes ready to use, right out of the box. Well, except for the distilled water that you have to get on your own! It's also offered at a relatively low price, compared to other high-performance external watercoolers.

Because of its ease of installation, excellent build, good performance and competitive price, we gladly award it our Editor's Choice Award! Congratulations, Corsair!

* Our New Review System

ARP is committed to developing new ways to improve your experience with us. As part of our continuous efforts to improve the value of our reviews to you, we are implementing a new review system.

This new review system is designed to allow you to quickly receive information on the latest hardware. This new system also allows you to quickly get the gist of the review without reading through it. This can be very useful, especially in situations where you need to make a quick purchase decision.

In this new system, we start with a Product Overview whenever a company sends us a press release about their latest product. We shift through extraneous PR-talk to create a straightforward summary of the product's features as well as its specifications. This allows you to quickly find out all the pertinent details about the product, without reading through official press releases.

When we receive the product for review, we will quickly take photos of it and create a Pictorial Review. The purpose of a pictorial review is to allow you, the reader, to quickly examine the product visually. It may help you make better purchase decisions, especially if you cannot wait for the full review.

After thorough testing, we will post a Comprehensive Review of the product. This adds on to the pictorial review with comprehensive test results and our final conclusion on the product.

But no matter whether you are reading a Pictorial Review or a Comprehensive Review, you can always read the summary of the review as well as examine the product's specifications right on the first page. In all our new reviews, we will maintain the first page as a Product Overview page. If the product is listed in PriceGrabber, you can also check out the lowest price online.

We hope this new review system will make your experience a lot more enjoyable and informative!
