5 out of 5 eggsGood performance and value

Pros: • Sturdy packaging
• Mounting hardware for all modern consumer sockets
• Price is comparable to similar performing coolers
• Performance is comparable to similar priced coolers
• Installation is “possible” with a preinstalled motherboard
• Fan brackets are surprisingly easy to work with
• Pretty quiet for the level of received performance
• At stock voltages on two different procs – performance is within a couple degrees, using a single fan instead of two
• Mounting system places it about a ½” lower on the motherboard than most coolers this size

Cons: • Large size pretty much demands a full tower case
• Depth of cooler creates some “hang” off the motherboard
• Performance at this price will cost you
• Not very attractive for window builds
• Using both fans limits you to standard height ram – and blocks three RAM slots

Notes will start here:

Outside of physical looks, I was pretty impressed with what the Neptwin had to offer. I feel that just about ALL coolers this size, especially those with dual fans, look ugly in an otherwise attractive PC build. That aside, performance is what counts, and the Neptwin delivers in all of the ways that you would expect, as well as having a couple of nifty design tricks up its sleeve.

Installation was easy with the motherboard outside of the case, taking just 16 minutes from start to finish. Installation inside the case, while doable, was really tough. Part of the issue was the size of the Antec 1900, as I spent part of the install with the case tilted. Either install method will involve a standard Phillips screwdriver to tighten the screws on the holding plate. You have to leave the center fan uninstalled to do this, and thankfully, the included fan brackets are very easy to work with, to a point, I was able to install/uninstall both fans with the motherboard mounted – no issues at all. The mounted cooler also leaves enough space for easy top-mounted fan clearance.

I tested the Neptwin on two processors, using Prime95 (small FFTs) and a few rounds of Linpack. The room temp as about 19* Celsius, and the case used was an Antec 1900. I’m only going to include load temps, because frankly – who cares about idle temps!? Even the extremely lame Intel stock cooler maintains respectable idle temps. I also left the fan(s) on “auto”, allowing the motherboard to ramp them up and down.

Other Thoughts: Intel G3220@3.0 GHZ loaded at 45* Celsius after 22 hours of Prime95 Small FFTs (for maximum heat). No overclocking here, as the G3220 doesn’t allow it. The Neptwin produced identical temps with a single fan, or two (I removed the fan mounted next to the RAM after about 8 hours) with RealTemp logging 46* Celsius as a maximum.

Intel 3570k@3.40 GHZ loaded at 43* Celsius with 10 passes of Linpack. Same results with a single fan. Things got a little interesting as I added voltage. Max overclock was 4.46 GHZ@1.24vts. Temps averaged 65 Celsius with 10 more passes of Linpack. When I removed a fan, the Neptwin started to struggle, as temps climbed to 72* Celsius. So good news is that you can get away with running a single fan on the Neptwin, but don’t expect to break any temperature records. I will also say that with higher ambient temps in the summertime, you can be assured that single fan cooling on the Neptwin will get out of control pretty fast.

The Deepcool Neptwin delivers on performance, and gives you the advantage of running with a single fan (at low overclocks), with full access to all four RAM slots – and no restrictions on RAM height. Granted, most people will run the Neptwin with both fans, as these same people will be shooting for higher overclocks.

CPUs run on suck low voltage now, that a cooler this size isn’t really necessary if you are keeping things at stock. But turn up the juice, and the extra heat pipes/fin surface area will deliver enough of a performance boost to justify the extra dollars spent. Just make sure you pay close attention to the mounted height, and choose your case accordingly.

4 out of 5 eggsWorks but overkill

Pros: Well, there is no doubt that this works well. These numbers are from a computer running in my basement so it will be a bit cooler than normal (still impressive though). The processor is a Haswell i5 running at 3.5GHz.

Idle: 23C - 25C
Load: 36C - 40C

-Works great
-Quiet fans
-Nice blue color
-Stable mounts once you get it in

Cons: Even though it does do what it is designed for, there are definitely some cons. For starters, mounting. The mounting is quite hard to do and even though the instructions are acquitted, the installation itself is difficult. In order to put the support mounts on, you have to use these really weird screws. They are flat and once you finally get them started to screw in, they push a phillips head right out. There is no reason for them to be such flat screws in the first place You basically have to push really hard on the back of your motherboard and use a flat head screwdriver.

Another con is obviously the size. It will not fit in all cases and there are smaller ones that will do almost as well. In my Gigabyte G1.Sniper mobo with G.Skill RAM, I had to move the fans to face the other direction in order to have room for the RAM.

-Very large (obviously)
-Difficult installation

Other Thoughts: So if you can get it installed in your case, you will be a happy camper. It does exactly what it is supposed to do. The problem is there are a lot of other heat sinks that are smaller and cheaper that work about as well. So... your move.

4 out of 5 eggsGood but not Perfect

Pros: This is a solid cooler and it's a very good value.

To test it I used RealTemp and Prime95. I ran Prime95 for 2min then recorded the highest temp. Trying to keep it simple. My CPU is a 5930K in a TJ11 with the sides off. The Prime95 test I ran was the Blend Test because it could not handle the Small FFTs (max heat) test. See other thoughts on that.
Clock Spped
3.5GHz 45C
3.7GHz 48C
3.9GHz 52C
4.1GHz 53C
4.3GHz 59C
4.4GHz 64C

As you see good results with this 6 Core, 130W cpu which has a stock Turbo Boost of 3.7GHz.

The cooler I have is a liquid cooling loop with a 3x120mm rad. This does not do any better until above 4GHz where it starts to take the lead. At 4.1GHz they were still the same but at 4.3GHz the liquid cooling was 3 degrees cooler and at 4.4GHz it was 5 degrees cooler.

The build quality seemed pretty solid and the bottom was a mirror finish.

Cons: While it performs well for the price I can't give it five eggs because well, it's a giant and does not blow my mind in performance.

Depending on the shape and height of your ram heatsink this may hit. I had to sit the one fan a little high on the fin array because of this.

The fans are fine but are not the highest airflow. If you want to get the most out of this you will be buying aftermarket fans which takes away the good value.

The packaging was also less than 5 egg worthy. All of the parts for the various sockets were in separate plastic bags but the bags were staples shut rather than being resealable zip locks or taped so as not to tear then when opening..

Other Thoughts: I could not run the Small FFT test with this cooler. I took the clock speed down to 3.2GHz and the temps would immediately shoot up to the 80's and I had to stop the test in less than 2 seconds. The liquid cooling loop I had maxed out a 66 degrees after 10 minutes doing this. So unlike the Pros section test, you can really see the liquid cooling show how much better it is here. I put this in other thoughts because normal applications is going to cause this kind of heat. Also wanted to have a comparison so that my Pros section did not was not misleading readers into thinking this product was as good as liquid cooling.

3 out of 5 eggsWorks Great, Terrible to Install

Pros: -Reduced my CPU temp while running Prime95 to a peak of 51c.

Cons: -Horrible to install. It took 3 hours and heavy jury rigging to install. The stoppers to hold up the bracket were made too large and could not be installed using all 4 of them. The recommended positioning on the motherboard could not be accomplished either. One of the 2 fans had to be removed in order to install to allow for airflow.
-Leans against one of my RAM sticks.

Other Thoughts: Overall if you can make it fit/work it does seem to provide excellent cooling. The rating is for the extremely high level of difficulty to install, and not being able to be properly installed.

- I did not use the stock thermal grease provided. I instead used the Antec Formula 7 so this may be contributing to my temperatures.

4 out of 5 eggsHigh Quality heatsink

Pros: Powerful
Two Fans
LEDs are bright
Looks pretty good

Cons: Somewhat difficult to install
fans have an odd way of mounting
Absolutely Huge

Other Thoughts: I made the mistake of installing this monster heatsink while my case was upright, so I had a difficult time mounting it. Instructions were a good place to start, but were just pictures, no steps. It can keep my 4790k at ~80 Degrees Fahrenheit at full load.

4 out of 5 eggsneeds a little mod to use

Pros: seems to cool very well. Watch out for pins on back of MB that could short to supplied rear bracket.

Cons: rear brackets sits on some of the through pins. Bracket is designed like a double "X", and the non used part of the "X" for my "Asus Crosshair V Formula-Z AM3+ AMD 990FX +" board would have shorted out part of the MB. Using a good pair of pliers I bent those non-AMD "X"s back and forth until they broke off.

Other Thoughts: Would have been better if the original bracket could have been used as base for this heat sink. Also original rear bracket is heaver, less flexible and stronger then replacement bracket. It seems the mounts for the heat sink is pretty much standard and would have been better to have used standoffs with wider holes as spacers along with longer screws and used pre-existing rear heat sink bracket and it's stand offs. Would have been a lot less trouble trying to fit a "one size fits all" rear bracket.

5 out of 5 eggsMonstrous Heat sink

Pros: This thing is huge, keeps a socket 2011 - 3930k extremely cool even overclocked and running video conversions. Very nice looking. Quiet, even under load. I noticed +10 Degree lower temps during video conversions lasting over an hour. Easy installation. I already had a blue theme so worked very nicely in my setup. Gaming wouldn't even challenge this. Worth every cent!

Cons: A bit too big for the average setup.

Other Thoughts: Make sure this will fit. If it will it will outperform many other CPU coolers... maybe all.

5 out of 5 eggsGreat Cooler for the Novice Overclocker/Gamer!

Pros: Right off the bat, I was blown away by this product. The packaging was so organized and well labeled. I found the instructions to be easy to follow for any tech level. And another HUGE plus that anyone who has been building Intel based computers over the years can vouch for: easy mounting hardware without those darn Intel push-pins! Also features compatibility for many versions of processors/motherboards which is a great touch.

After installation with some arctic silver compound, I connected the fans and booted up the PC for some comparisons. Running an Intel Core i7 overclocked slightly to 3.5GHz I saw idle temperatures below 30 C! Normally my setup would run at roughly 35 C idle so this is a good improvement.

Running full load gaming on dual monitors only pushed the max temperatures up to 48 C. That again is about a 10 degree improvement over my older cooler which had max temps around 57 C.

Next up is the full load test which included a maximum burn on Prime95. After several hours, the max temps peaked at 55 C which is well below my safe zone of 70 C so I am overall very pleased with the results!

Cons: For once I can't think of a single con worth mentioning for this product. I rarely give 5 egg reviews because I can always nit-pick on some feature or flaw, but with this device, my personal experience has been flawless.

Other Thoughts: This is a big cooler, so be sure your case has plenty of room around the processor for it to fit. Also, some window panels that have fans on them may get in the way slightly. It just depends on how thick those side panel fans are and how wide your case is.

If you like blue LEDs, these will fit in very nicely with your setup.

If you are looking for a great cooler for a gaming build or only mild overclocking, this will do the trick. For heavy overclocking, I always recommend liquid cooling, but anything around the 4GHz or under (depending on processor of course!) should be safe to try on this monster.

5 out of 5 eggsHuge Size, But Very Effective

Pros: This cooler was highly effective for me. I have a Core2Quad Q9550 which I wanted to cool down. I did not come from a stock cooler, I came from a decent aftermarket cooler, but after an overclock on the processor to 3.00GHz, the processor would regularly reach 70C and that was the point where I had the thermal alarm set to.

After installing this CPU cooler, I am not bumping up against 70C anymore under high load, and I am considering overclocking further!

The fans move a lot of air as expected, and they are also very quiet. This is one of the major benefits you get when you go to a larger fan.

I do not have a transparent side panel on my computer, so the blue LEDs just lead to a glow coming out of the various air vents on the computer. If you had a transparent side panel, as a lot of people’s gaming machines do, this might look really cool in there.

Cons: The major con of this cooler is the enormous size. Definitely do pay attention to the dimensions, there are plenty of computers I have worked inside before where I know there is absolutely no way that this CPU cooler would fit.

This CPU cooler is only for you if you have a nice big tower with a lot of open space. Please do pay attention to the dimensions before you order.

Other Thoughts: Overall, I am very impressed with this cooler and I would consider buying it for future builds. But, I would definitely make sure that my motherboard layout and case layout would not interfere with having this huge bulky cooler installed. Installing it in my existing machine was a shot in the dark, and I definitely feel that I was lucky that it fit. It was really close to not fitting because the fan built in to my side panel almost touched the CPU cooler.

5 out of 5 eggsBig but good design / Great performance

Pros: This heatsink is huge but I had not problem with installation. Smart design with heat sink allowed room for RAM with heat sink. Installed this on a Phenom 965 running at over 4ghz that had an H60 installed. Used a y-cable to hook both fans on cpu fan header - bios fan speed worked fine even though I was only using 3-pins.

The included fans are quiet - well quieter than my Antec case fans because I could not hear them running. This heat sink with an overclocked 965 actually ran cooler than the Corsair Hydro H60. About the same temps at idle, but running a performance assessment tool pegging the CPUs at 100% showed this CPU running a few degrees cooler. One thing I did notice is when going from 100% CPU back to idle, the CPU temps dropped much quicker with this than the H60.

Okay not really a PRO unless you are an old geek like me, but this huge heat sink looks cool. I am probably going to keep this installed and put the H60 on the shelf.

Cons: Size, but not really a con. Because of the size, I wanted to be careful, so I removed my motherboard and components, installed the DeepCool, and reinstalled the motherboard. Took a little more time, but made the job easier.

Other Thoughts: I liked my Hydro cool but I did not think the performance was all that great. I was surprised at how well this DeepCool performed. Now that I have it installed, I may try to push my old 965 BE up a few more notches since it is cool enough under load to push the voltage a little. The water coolers are great but I did find they have a big disadvantage - if the pump ever goes out, you won't know until your system shuts down. With air cooled, the system will shut down if my cpu fan fails. I had a Thermaltake Big Cool I was running in a 955 overclocked and it shut down on me one day. When I tried to power back up, it would shut back down. I pulled the case an the CPU was so hot I could smell it. The pump on the Big Cool went out - no warning - no indication - no way to tell until the CPU was hot enough to cook some eggs.

This is a little expensive for air cooling, but well worth it. You get performance equal to many liquid coolers and that makes the price actually inexpensive if you are considering liquid.
