The NZXT HAVIK 140 is the company’s first foray into the competitive air cooling market. It will be interesting to see if NZXT just cobbled something together or if they did some serious research into cooling modern CPUs.
NZXT was started in 2004 in Los Angeles, California, with the original intent of being the number one designer and manufacturer of computer chassis, like the NZXT Phantom. Since then, they have expanded their lineup from being chassis specialists to supplying power supplies, fan controllers and fans, mice, notebook cooling and even premium computer cabling. Now they are looking to get into a highly competitive market; high-end air CPU cooling. They are going against established names such as Thermalright, Cooler Master, Noctua and Prolimatech that already have plenty of market presence, so they have better done their homework with their initial cooling solution.

Looking at these features and specifications, it looks like NZXT was serious about putting forth a good product for their first cooling solution. The basic layout of the NZXT HAVIK 140 is much like other high end coolers such as the Thermalright Archon and Prolimatech Megahalems, with a rectangular shaped central fin body and using six heatpipes. Like the Archon, this heatsink comes with 140 mm sized fans, but two of them instead of just one like the Archon. This heatsink also spaces the heatpipes evenly across the full heatsink instead of of just making a couple of rows behind each other like the Venomous X or Megahalems.
This heatsink also has the same height as most heatsinks designed for 120 mm fans at 160 mm tall, which is very welcome as far as accommodating it in your case. They aren’t kidding about the fans having unique fan blades either. They are quite steeply pitched and they have “snake-like” bends to the blades. I haven’t seen any other fans designed quite like these and I don’t see them listed on their website for sale, so I am guessing that they had these specifically designed for this heatsink.
This heatsink is also a true “out of the box” solution, with all fans and mounting equipment for any modern Intel or AMD system. The bare heatsink had a measured mass of 734.5 grams and the fans came in at 150.5 grams each. The rubber straps used to hold the fans on the heatsink have a mass of 5.2 grams per set and the total mass of the heatsink and fan combination (including the fan mounts) comes in at 1031.4 grams.
The heatsink ships in a nicely finished box measuring 8 1/2 X 7 7/8 X 5 15/16 inches (217 X 198 X 150 mm). Upon opening the box, you see that NZXT didn’t try to cheap out on the packaging, as the fans and heatsink are very well protected by form-fitting foam pieces that the components fit inside. On the front of the box, the marketing flack has been kept to a minimum, with the heatsink’s name printed on it along with a good picture of the heatsink with the fans installed and a short row of features posted in small boxes. The two sides of the boxes have pictures of the assembled heatsink taken from their respective sides along with some marketing spiel pointing out features on one side and the other has a paragraph telling you why their heatsink is so special. The back side of the box has more pictures, specifications and highlighted features they want to point out to potential customers. The overall color scheme on the packaging is well done in blacks, whites and grays and isn’t gaudy at all. Nice job on the whole, NZXT. I noticed a few misuses of words in their marketing; mostly common mistakes such as using “quite” when they mean “quiet”, but nothing that makes you scratch your head wondering what they were trying to say.
First Look and Installation
After removing the heatsink from the packaging, I saw a well designed and executed heatsink. The fit and finish of the heatsink and the parts included for mounting it are very good. The size of the actual heatsink itself (without fans) is very close to the same size of a Thermalright Ultra120 eXtreme (TRUE).
The instruction sheet included with this heatsink is basically a foldout poster sized piece of slick paper with pictures of the heatsink and hardware, along with a parts list breakdown on one side. The other side contain the instructions in nine different languages. The instructions are mainly depending on pictures, with a few comments per picture. I had no particular problem figuring out how to mount the heatsink.
The mounting method that NZXT decided to go with for Intel setups looks somewhat like the system used by Prolimatech with the Megahalems and Thermalright with the TRUE Rev. C, with a crossbar plate going over the heatsink base and screwing down to side rails. NZXT uses an all-in-one backplate though, that takes care of all modern Intel sockets and also AMD too, instead of having separate backplates. There are four riser screws that you install in the appropriate holes in the backplate for the socket you are mounting to with Intel, then run the riser screws through the motherboard. Then you slip on four plastic spacers on the riser crews and install the two side rails that the crossbar with screw down to. The crossbar is around 1/2 inch wide and has detents punched into it to center the heatsink. The heatsink base also has a machined slot on the top of it that the crossbar fits into, limiting side to side movement when the heatsink is mounted. The mounting system works well and is quite easy to install.
As for the heatsink itself, the fit and finish on it was flush and smooth. The base isn’t finished to a high gloss shine like the Venomous X, but had a good finish to it. The base is also bowed across the longitudinal axis, much like several other high end heatsink designs out there. I find that this does help with getting a good mount and makes sure that you get the best contact you can in the middle of the processor’s IHS, where the most heat will be concentrated. The heatsink itself is much the same size and shape as a Thermalright TRUE Rev. C. I took a few pictures of them side by side to highlight the similarities and differences.
The fans included with this heatsink aren’t the usual square design, but rather are round, with mounting holes protruding on both sides every 90 degrees. The mounting hole spacing on the fans is the same as on regular design 120 mm fans, which opens this heatsink up for mounting most open corner 120 mm fans on it too, if you want to look for more performance. The mounting system for the fans is a bit unconventional. Instead of using wire clips or brackets, NZXT uses some rubber pieces that connect between the two fan mount holes on each side and then you stretch the rubber band across the sides of the heatsink to some catches designed into the fins. It holds the stock fans securely and can even hold my Sanyo Denki compound fan securely, but I still don’t like this method of mounting fans to the heatsink. First, I found it to be kind of difficult to mount the fans inside the case because of clearance issues on the sides of the heatsink and I am using a large, full tower case. For someone using a mid tower or smaller case, especially if it has a top mounted PSU, might find it extremely difficult to hook the rubber strips on the side nearest the PSU without removing the PSU.
The main reason I don’t like it is that rubber will harden and crack as it gets older. So a few years down the road, you go to clean the dust bunnies off the heatsink and go to remove the fans and the rubber breaks. Then you are in a pickle because the heatsink doesn’t ship with spare rubber mounts and you will have to either try ordering some new rubber mounts from NZXT (and costing you some more money) or you will have to try to jury rig the fans with zip ties to the heatsink. I would much rather see a company use wire mounts like Thermalright and Prolimatech or use brackets like Cooler Master does with the Hyper 212 Plus. I was hoping to find some wire fan clips that will work with this heatsink, but I had no luck. I tried the Thermalright wire clips for a TRUE and they won’t work. I then ordered some Prolimatech wire clips for a Megahalems, but they are just a little too long. I could modify them though by shortening the depth of the clips by bending them and then maybe putting some of the rubber strips that Thermalright ships as vibration strips with their heatsinks on the heatsink body itself.
No real problems were encountered by me when using the various different fans with the NZXT fan mounting system. That is, besides the narrow clearances on the sides of the heatsink when hooking the rubbers on the hooks built into the sides of the heatsink itself. Wire clips would be much preferred.

I decided to phase in using the AP-15 Gentle Typhoon fans in place of the S-Flex SFF21F fans I have been testing with. The Gentle Typhoon fans have shown to be excellent performers both on heatsinks and on radiators and their sound is both quiet and unique in that it is a different pitch than most other fans around, which is very non-intrusive.
The testbed system is configured as follows:
- Case – In Win Dragon Rider. The 220 mm side door fan has been shifted downward to give clearance for tall heatsinks such as this one. No other alterations have been made to this case.
- Motherboard – Asus P6T
- Processor – Intel Core i7 930, overclocked to 4000 MHz @ 1.304 v.
- RAM – Corsair XMS3 DDR3 1600
- Video Card – eVGA 7900GTX
- Power Supply – HEC Cougar series S700
- Hard Drive – Western Digital Caviar 250 GB SATA hard drive
- Optical Drive – Lite On DVD-RW drive
- OS – Windows Vista Ultimate 64 Service Pack 2
- Arctic Cooling MX2 thermal paste was used for testing as I have found it to give good consistent results with no appreciable break in and it applies and cleans up easily.
- All testing was done with the side door fastened in place on the case except for the Sanyo Denki 9CR1212P0G03 compound fan. I left the side door off on that one to keep from trapping air, since that Beast moves so much.
Test Methodology and Results
The testing methodology used is the same as I used with my previous reviews:
All energy saving features of the motherboard and processor were turned off to keep it from down clocking the processor speed and vcore. All fan control functions were turned off in bios to keep the fans at maximum speed. For processor temperature monitoring purposes, I am using Real Temp 3.46, with logging enabled at 2 second intervals. For room temperature monitoring, I am using a Fluke Model 52-2 and using a “K” type thermocouple that is inserted into the case front where the front intake fan is mounted. The Fluke records the maximum, minimum and average temps during the run at 1 second intervals.
Temperatures in my computer room were maintained as close as possible to around an 18 °C average during the run, as measured at the lower front intake fan by the Fluke. At the end of the test run, I logged the maximum, minimum and average temperature. The maximum and minimum temps are given as recorded by Real Temp, but the average temperatures have been adjusted to a constant 18 °C as derived from the Fluke average temps.
For loading the CPU, I used Prime95 version 25.8 using in-place large FFT’s and ran it for 30 minutes to stabilize temps. After 30 minutes, I would exit Prime95 and let the CPU idle for at least 10 minutes. The highest recorded temperature from the hottest core for each run was then recorded off of the Real Temp log, the lowest temperature on any core was recorded and the average temperature on the hottest core was calculated during the load portion of each run.
Each fan configuration was tested with three remounts of the heatsink, and the lowest average temperature run recorded, to minimize any problems between mount to mount installations. When testing in the extreme performance realm with the SanAce 9CR1212P0G03, it was installed in a push configuration, just like my tests with it on the other premium heatsinks I’ve tested.
The following chart gives the results I obtained with the fans tested above:
As you can see, this heatsink performed very well with the included fans. Performance picked up slightly with the Gentle Typhoons and there was continued scaling of cooling ability until it got to the point of the Delta fans. The big Sanyo Denki Beast saw hardly any improvement in cooling, which surprised me to say the least. But, that is on the very extreme edge of air cooling performance, and for 99.9% of people out there this is no problem. To see how this heatsink stacks up in its stock configuration against other recently reviewed heatsinks, we have the following chart.
The performance of this heatsink compares very well to the other heatsinks I have tested recently. It performs almost 4 1/2 °C better than the next best heatsink to it that I have tested their stock configurations. If increased noise doesn’t bother you, throw a pair of Sanyo Denki H1011 fans on it and gain another 5 °C better average temps.
Since this is a brand new product, we can’t go looking around the net to find retail pricing on it, but the MSRP is $74.99. At first glance that seems to be a high price, but you do get a complete cooling solution, with nothing else needed. At this price point, it is in the same general pricing range as the Noctua NH-D14 and Thermalright Silver Arrow, which are also complete cooling solutions and direct competitors of the Havik 140. What you get for your money is a very well-built heatsink that has very good “out of the box” performance and has a quality mounting package.
Where I find it somewhat lacking is in the attach mechanism that NZXT chose to use with the fans. While it does hold even very heavy fans such as the compound Sanyo Denki securely, it is still a bit of a pain to mount the fans on the heatsink with the motherboard inside the case, even though it got a bit easier with practice. You can add to that my concerns about the long term durability of the rubber straps to not break as the rubber ages and hardens. If NZXT would come up with some wire clips that engage the hook strips on the side of the heatsink like Prolimatech did with the Megahalems they would have a sure-fire home run here.
But, fan mounting concerns aside, NZXT has brought a very good product to the market and considering it is their first cooling product, a heck of a good job. As such, this heatsink earns itself an Overclockers Approved rating.
In closing, I would like to thank NZXT for giving me the opportunity to review this product before its official release. You guys have done a good job on your first effort in the highly competitive cooling market. If you address my few concerns on your fan mounting attach mechanism, I think you will have a good chance of breaking into the high performance air cooling market and be talked about side of such names as Thermalright, Prolimatech, Noctua and Zalman.
