Outstanding Cooling Performance:
Designed with enthusiasts in mind, the new Nautilus500 brings 30% more CPU and
40% more GPU cooling efficiency without excessive noise. While overclocking is not
guaranteed by any one component, the degree of system overclock generally
correlates with the degree of component cooling. The new Nautilus500 brings a new
cooling solution to overclockers with its all-copper CPU block and Micro Channel
Technology?. The Nautilus500 CPU cooling block provides maximum heat absorption
and most efficient heat transfer. Fan speed can be adjusted to suit individual needs.
When high fan speed is enabled, cooling performance is maximized. When low fan
speed is selected, the Nautilus500 cools effectively with minimum noise generation.

Ultimate Ease of Use:
Complicated installation processes and unproven reliability have traditionally been barriers of entry for enthusiasts looking
to use watercooling solutions. Corsair?s new Nautilus500 features a QuickInstall? design that allows any user to install
the complete kit easily without having to remove the motherboard from the case. Compared to other watercooling
solutions currently available, the Nautilus500 is undoubtedly the most user-friendly solution. Each complete kit includes
pre-fitted, pressure tested tubing that can be adjusted to any length without the fear of accidental leakage. For mobilityminded
users, the kit also includes quick connect self-sealing connectors to avoid having to drain the liquid during

Configuration Flexibility:
The Nautilus500 complete kit can be used on any processor type, including Intel® LGA775, socket 478 and AMD®
sockets 754, 939 and 940. To deliver maximum configuration flexibility, the cooling unit is adaptable with additional GPU
and north bridge blocks. Both blocks are sold separately and can be daisy-chained to the CPU block without cooling
performance degradation.

5 out of 5 eggsStill using this to this day.

Pros: Super efficient, quite, dependable. I love this cooling system, but there hasn't been one in existence anywhere near the price point ever since. I would buy 5 of these today if corsair still made them. This unit has been running 24/7 for over 5 years without a problem across multiple chips, currently cooling an Intel 960 keeping it at 26 degree's c on an X58 classified.

Cons: Have to add cooling fluid once every couple months, and corsair has discontinued this, but WHY?

Other Thoughts: If corsair would bring this back to market, I know it would be a regular seller.

5 out of 5 eggs5 Years Later, Corsair Nautilus 500 Still Working Great !

Pros: I posted a few reviews and updates for this water cooling kit on here. I originally bought this back in October of 2006, from Newegg. Here we are 5 years later. I have upgraded my computer many times over, but I've always kept the Corsair Nautilus 500, because it has always worked well. I just recently upgraded to an i5 2500k, and have it overclocked to 4.7Ghz, being cooled by the Nautilus 500. The Laing pump is of great quality. I even added a 240mm XSPC radiator into the loop, to go along with the Nautilus' 120mm rad. The pump easily handles the 240mm radiator, as you can see the air bubbles whip through the tubing. The cooling is excellent. I ran Prime 95 stress test and Real Temp, my temps were 23-25c Idle and 42-45c full load. Make sure to keep your radiator clean of dust, up the top and the bottom, and your cooling will be great. I had to take mine apart, to clean the radiator, because I let too much get clogged inside of it, but now it works like new, no dust at all.

Cons: There are no cons. The fans push almost 80cfm, at high speed. In low fan mode, you can't even hear the fan. At high fan mode, you can hear the fan, but it's not very loud or annoying. There is definitely no whining noise, like I read in some other person's review. There is also no gurgling sound whatsoever from the Laing pump. The only thing that I had to do recently, with my newest build, is to purchase a new water block, since there was no i5 or i7 mounts back in 2006. I went with a Swiftech Apogee XT, and it looks great, and works great.

Other Thoughts: All in all, this thing has paid for itself, a few times over. I always saved money purchasing OEM cpu's, and I always get double the performance over a stock cpu, because the Corsair Nautilus 500 keeps all of my overclocked processors as cool as ice. Almost 5 Years to the day later, when I originally purchased this kit from Newegg, and it's still working like a top, as I said in my initial reviews, and follow up review, a couple of years later.

5 out of 5 eggsworks perfectly!

Pros: kit comes w/ every thing, easy to install and maintain. cools my x2 6400+ 65 deg. f. idle, 85-90 deg f. after 4 hours of crysis or CoD4. after a year and two systems, including some time spent also cooling an HD 3870 oc,d, which averaged 36-38 deg c. under load. it still works perfectly.

Cons: NONE

Other Thoughts: very easy to set up and suprisingly effective it if you can find it!!

5 out of 5 eggsGood Cooling!

Pros: Had this unit for a year and it works great, added a 240mm radiator and two smart fans to cool a q9550 oc'd to 3.93 and a video car and thats the 3rd cpu and motherboard i have used it on. All fans on low cpu gets to 110f and video gets to 125f with everything maxed.

Cons: Tubing is hard to use, get something more flexible it will make you life easier. Primoflex works the best.

Other Thoughts: Use metal clamps. Personally i dont like to keep any heat transfer devices inside the case and this can sit on top or next to it without adding any heat inside. Use only distilled water in case you do have a leak! I didnt buy this from Newegg because they were out of it but i wished i did because they are great!

2 out of 5 eggsPump failing, corsair does not support product

Pros: The unit is small, easy to install. Cooling is as good as I expected from it. It connects to the PC's power supply so there is no worry about forgetting to turn it on. Also unlike my previous liquid cooling product, it does not leak when you tip it.

Cons: Within about 3 months my unit started to have a problem with the pump. Corsair tech support confirmed this problem by listening to it over the phone. The unit does still work and cools my CPU but the pump makes an unbearable loud buzzing noise - my computer sounds like a jet engine.

Corsair is unable to support or standby this product at this time, according to them. They offer a partial refund but no suggestions as to how to cool my computer with that.

Other Thoughts: If I hadn't received a defective unit, I think I would have been very happy with this product. Good design, works well except for the noise.

Manufacturer Response:

Please contact our Technical Support supervisor. We will resolve this Nautilus issue for you ASAP.

5 out of 5 eggsCorsair Nautilus 500, 2 Years Later

Pros: I posted about this product back in October of 2006. My original reviews with temperatures, etc. are back ok page 5 and 6. I have owned the Nautilus 500 on for just about 2 years and it is still spinning like a top, working great. The temperatures are exactly the same as the day I set it up. Just make sure to clear the dust from the bottom of the radiator every so often.

Cons: The only thing I didnt like was the pci bracket pass through holes, for the tubing.I was thinking that I was going to puncture the tub because the tube fits in there tightly and scrapes against the side as you are slipping it through. I replaced the pci pass through holes with a Koolance VLV-10BKT 10mm (3/8") ID Quick-Disconnect Shutoff Valve Pair w/ L-Bracket.

Other Thoughts: Cooling of an Intel Core2Duo E6600 on a
ASUS P5B Deluxe

2 out of 5 eggsworked, WHEN it worked

Pros: Did what it was supposed to while it worked.

Cons: Within less than 4 months of owning this product, the pump went out. Corsair support is laughable at best (see other thoughts).

Other Thoughts: When the pump went out, the next day I contacted the Corsair support phone line, only to find out that I had to file the problem via email! So I sent in 4 emails and no response! I had to call them with the threat of a formal complaint against the company to get any support at all. I ended up having to try to contact the manager to get a hold of the supervisor who was supposed to refund my money.... I'm still waiting on the check..... They were "supposed" to send it a little over two weeks ago

Manufacturer Response:

Please contact Customer Service again and we will resolve this for you ASAP. For future reference, we have 3 methods to obtain support;

5 out of 5 eggsAs a newbie to liquid cooling, It works just fine for me.

Pros: Simple installation, Does it's job well.

Cons: It would have been nice if the kit came with some ribbed flex hoses for tight curves. As it is, my setup has some kinks.

Other Thoughts: I hate Jack Thompson, ceterum censeo Carthaginem esse delendam.

1 out of 5 eggsStock Air vs Nautilus

Pros: The best things I can say about the Nautilus 500 is that if you like to laugh tell you cry give it a shot.

Cons: I tested against stock cooler for AMD 5200+ along with my tried and true Zaluman and both were at full load what this was at idea. Zaluman for me runs at 39C under load with room temp of 75F. Stock cooler was running at 42C with same room temp. This is the first time on a full kit water cooler with the outcome some what expected it was still an amazing laugh. The build quality leaves something to be desired it felt like to me that was was going to snap if I touched it. Hoses came smashed. Wiring connections are a joke wires poped right out from there connectors after putting on the floor. What more to say unit is trash will be returning it Saterday not worth RMA just cash back.

Other Thoughts: I've never had a problem with Corsair but in this they need to stick to what they know best or at least hire someone that dosent want to cut every corner just for cost saving.

Manufacturer Response:

Based on your post, it sounds as if you may have installed the CPU block incorrectly or that there may be an issue with the unit. This unit will easily outperform the stock cooler so your results are atypical. Please contact Technical Support for assistance.

5 out of 5 eggsGreat Product!

Pros: Easy set up. Never leaked. It took about 3 days for all the air to work its way to the reservoir, topped it off and after a year and a half and 2 military moves (gorilla packers hired from Samsonite commercials), I haven't cracked it open since.

Cons: As this is my first and only liquid cooling system, I don't know if its the norm, but it seemed like a lot of pressure I had to put on the CPU to get the cooling block to clamp down.

Other Thoughts: I was nervous about going liquid cooled. Who wouldn't? But after alot of research I went with this unit and never looked back. The connectors are solid. I've read some complaints about the aluminum radiator and it not being protected. Its in a solid base and unless you plan on throwing it around, I can't see how you'd damage it. I always run my fan on high and its not loud by any means. Even in my room at 80f, the highest the cpu saw was 81f, running COD4 online...
