5 out of 5 eggsLove it

Pros: Keeps my i7 4770K 10 degrees cooler than stock heat sink and 20 degrees cooler under 100% load with prime95. I saw some reviews stating a 2 degree temp difference, they must be high! One review complained about the brittle plastic mounts, I also messed up om the first try and didn't get the anchor properly seated but I "uninstalled" it and bent the white plastic back into shape (not brittle at all) and re installed it. I highly recommend you do this with your pc laying on its side.

Cons: Your kidding right!

Other Thoughts: Like other people I would like to add another fan to make a push pull configuration so I emailed the manufacturer but like so many overseas company's I got no reply...
Still I would recommend this product to anyone who wants a solid cpu cooler.

4 out of 5 eggsGreat cooling for a low price

Pros: I installed this in place of a Cooler Master Hyper 212 Evo, which works very well and keeps my Intel I7 3770 idling at 38*C with Arctic Silver 5 applied. This cooler maintained that same temperature at idle...I was surprised, because of how popular and highly rated the Cooler Master is on Newegg! I played Far Cry 2 for an hour or so and the processor never got above 55*C! I edited video and multi-tasked doing lots of different applications and that's as high as it got. It's very quiet even under load.

Cons: I took off an egg because I very much dislike the stupid plastic twist anchors for the Intel processors that this uses. A cooler this large should use a backing plate and screws to attach to the board, not the flimsy plastic things that get damaged easily. Also, the wire clips to hold the fan on seem kind of flimsy, also.

Other Thoughts: Besides the two small items I mentioned, this cooler works great and I would recommend it to anyone trying to save a few dollars and still get a product that does the job!

4 out of 5 eggsNice heatsink

Pros: Installed this on a i5-4690k to replace the stock intel assembly, the unit performs far better as would be expected.

Physically the unit was well packaged and arrive in nearly perfect condition (1 slightly bent and easily fixed fin, I find this pretty common with this style cooler). The construction feels solid, details wise it's clean and of high quality manufacturing.

One thing I particularly like is the added fins on the top of the base plate, while this probably doesn't make much measurable difference in operating temperatures it's not finned on most in it's class and I like seeing the little thoughts.

The bottom of the plate has a large "white" sticker that says removed, on most it's clear and I have seen my share of computers where the builder forgot to remove it.

The undercut on the fin array does allow some extra room which is nice as it can be tight on some mainboards, granted the fan is still 120mm however it leaves some room where it can be made. Due to where it is cut, it as well affects the cooling capability marginally.

The pipes are well finished, fins are smooth and with another set of fan hooks you can mounts another fan for push/pull.

One thing I always like to test on coolers like this is fanless operation. Due to the relatively high amounts of airflow otherwise in my case it was capable of keeping my chip in safe temperatures while playing BF4 and Diablo 3 for a few hours, peaked 80c, no throttling. (Don't try this at home unless you know what you are doing)

Cons: Rubber mounts would be nice to eliminate any noise that can come with clips, but there are some small rubber blocks on to avoid frame resonance with the cooler. (I didn't experience any noise, the clips are very tight)

The LEDS are a bit brilliant for my taste, I'll likely spray them with a frosting to dull them out a bit, as well as replace the fan. The included fan isn't bad, it's pretty quiet and moves a fair bit of air, but I'm going to be in need of something a bit more powerful for my overclocking.

The base plate could be soldered to the heatpipes, the gaps between the pipes and plate walls are not as thin as I would expect, I generally fill these gaps with some thermal paste. (A little on top of the plate and wipe it with a straight edge, I generally use small plastic cpu case.)

Other Thoughts: Overall this is a great unit and I would recommend it to anyone looking for a high performance cooler, best part yet it fits almost any moderately current socket and the mounting hardware is pretty easy, instructions are not great, I didn't even look and it was on in 10 minutes.

Price/Performance this cooler fits right in the mix and I'd even be so bold as to say one of the better ones.

4 out of 5 eggsSolid cooler

Pros: This cpu cooler was packaged well and there were no broken parts on arrival. I installed it on a AMD FX-4300 AM3+ board. The large size made it a bit difficult to put on but with a little planning it was pretty easy. After cleaning the old thermal paste off the cpu I dry fit it to make sure it would fit in the case and make sure the fan was facing in the right direction. All the mounting brackets were included and the fan was pre-mounted, which from other reviews I have seen I'm pretty happy I didn't have to fiddle with the fan. The mounting bracket for this cooler worked Excellent! I held the bracket up and didn't understand how it was going to fit, but after It was actually mounted to the cooler and I connected it, I was super impressed. It held the fan on tight, but not so much I felt it was going to damage anything. Performance. I was not super impressed with the performance of this cooler. Using HWmonitor I checked the temps before and after installation and for me I didn't notice much of a temp drop from the stock cooler. see cons. The fan on the cooler was quite, I loved the blue lights and the price range makes this a great option for a cooling solution.

Cons: The directions were not very good. They were not bad. I have just seen better. My temps didn't drop very much from the stock cpu cooler. I was a little confused, but at idle the fan would only spin in spurts. I wanted to make sure the fan was not broken so I ran prime95 to get the cpu nice and hot then the fan kicked on and spun constant for about a half hour till I shut prime95 off. Its interesting how the stock cpu fan spun all the time, it must have been struggling to get the job done, where as this cooler was so big the fan barely needed to spin. I'm not sure that's a con. I would prefer the fan be spinning all the time.

Other Thoughts: I enjoyed testing this fan. I have had other fans like this and hated them because of how poorly they mounted to the motherboard. I would surely recommend this fan to anyone looking for an inexpensive cooler.

3 out of 5 eggsDecent Cooler

Pros: ~Love that this lower end cooler chose to go the route of using heat pipes. This significantly helps dissipate heat that is generated while under load.

~Very lightweight, this affords users the capability to install this in a case without having to remove the motherboard to install a backplate.

~Integrated mounting system can be utilized by a wide variety of motherboard/processor configurations

Cons: ~ being lightweight has its downfall in that it feels and is rather flimsy. The fins are not soldered/welded onto the heat pipes and if one is not careful can easily damage and remove them. Upon my initial install on my motherboard I managed to remove two sections of the fins, I simply put them back on after straightening them out.

~ The fan mount is very flimsy as well, Instead of using the supplied wire I chose to use my fan silencer which is a piece of rubber that mounts to the fan holes and slips in between the fins of the cooler. I have used similar silencers in the past with great success but ran into the issue of the fins separating and coming loose just from the pressure of the rubber being wedged in between them. In the end I did use the supplied fan mount clips but was quickly put off by the annoying rattle of the fan against the heatsink when fully spooled up.

~ Last but not least the supplied instructions are rather weak and in certain mounting situations the supplied mounting methods may or may not work for everyone and it also would leave others to wish it included a rear mounting plate for a more solid install to the motherboard and cpu.

Other Thoughts: I personally use water cooling for all my PC's, I have been put off by air cooling years ago when I had a motherboard crack due to the massive heatsink that was used. In that instance the heatsink even used a rear mounting plate but the shear weight still managed to damage the motherboard.
This cooler would have possibly changed my mind to switch back to air cooling due to its lightweight design, but when its all said and done it does not keep my CPU any cooler than my water cooling did, which of course is to be expected. But I am an avid overclocker and I like to tinker with my computer setup all the time so for a stock computer this would be an ideal starter cooler, but, if you like to overclock I would look elswhere. There are plenty of other air coolers on the market that are capable of supporting stock and overclocked configurations so just keep an eye out for those and if all else fails there is always watercooling solutions that can appeal to everyone

4 out of 5 eggsA Competitor for the Cooler Master 212

Pros: Direct heat pipes, allow a much more efficient transfer of heat.
Supports multiple socket types right out of the box.
Light weight.
Performs surprisingly well, I will touch on this more in other thoughts.

Cons: While it is light weight, and because of this does not need a back plate, I would actually prefer a back plate mount. I just don't trust the mounting system.
Fan feels cheap and I fully expect either the bearings, LED, or both to go out relatively quickly.

Other Thoughts: My testing setup was a

I7 920
IC Diamond 7
HAF 932 case

I tested first with my existing TRUE Black running both Intel Burn Test and Prime95 while monitoring temperatures using RealTemp.

They I7 920 was set to stock voltage and Ghz with Hyper Threading enable just so there is a consistent baseline.

With my TRUE Black, my temps per core were 73, 74, 72, 73.

With the Deepcool Gammaxx my temps per core were 75, 77, 76, 77.

Before testing the temps on teh Deepcool I left it on for about 2 weeks just to allow the IC Diamond to "cure", even though it doesn't need it like AC5, and to better emulate a real world environment.

Back when I bought my TRUE Black it was the best air cooler on the market and it cost me $100. I would have never imagined at that time an air cooler would come out that would work nearly as well but at a 1/4 of the price.

Just to touch on thermal paste for a moment. When using a direct heat pipe cooler, you want to use the spread method for your thermal paste. The pea size dot method will not work as this cooler isn't able to get enough force since it lacks a back plate. Also, since it has direct heat pipes, there are very small gaps between the pipes and heat spreader and if you use the pea size method it will not spread out evenly.

Final conclusion. If you are in the market for a well performing "budget" cooler it's going to be hard to beat this one. When compared to they Cooler Master 212, this one beats it.

4 out of 5 eggsGreat temperature decrease

Pros: At first I did not expect too much since this is not what I would consider a "Premium brand". However, I was surprised with the performance and quality. The mounts for the heatsink held it on the processor better and more solidly than other "better" brands I have tried. I doubt it will ever be coming off on its own. The temperature difference was also huge.

Stock Intel heatsink
idle: 32C
load: 60-65C

This one
idle: 29C
load: 48-52C

As you can see, this heatsink does exactly what is is designed for and does it very well.

Cons: There were a couple reasons why I knocked off one egg. The first is price. For this price (currently $35), you could possibly get a better brand heatsink. The second reason is the fan mounts. The fan is just held on by flimsy pieces of wire. They are easy to mount onto any fan and don't slide much when you get it on, but I was not impressed with the low quality feel of just strapping the fan on by clicking a couple wires into place.

Other Thoughts: Overall, this is a good heatsink and definitely works for lowering the temperature by A LOT, but for the price and flimsy fan mounts, there may be better ones out there. Just shop around but make sure to keep this one in mind.

1 out of 5 eggsStay away! False advertising and potential for damage to board!

Pros: Looks to be able to fit inside most ATX cases with no hassle. Like most aftermarket coolers, it’s a vertical heatsink. The idea of the blue LED on the CPU fan seems like a pretty cool idea for people interested in making their case have an eerie glow.


I have an LGA2011 socket motherboard for my i7-3820. The Noctua NH-D14 I have as my current cooler fits with no problems. The Noctua came with all required parts needed to attach to my board, but the Deepmax cooler failed to do this. In the assembly instructions online, the mounting brackets were supposed to screw in to the case in holes beneath the motherboard.

The problem with this thinking is that those holes aren't always able to have something able to screw into them, which is why many motherboards and coolers come with backing brackets to complete the setup properly. The Deepmax cooler only came with the mounting brackets, and there was no way to actually attach it to my board. That’s a huge minus.

The other problem I noticed with this cooler is that even if it did include a backing bracket, the mounting brackets could potentially damage the motherboard, CPU or both! The systems for “adjusting” the length of the brackets to fit the cooler holes was shoddy at best, the screws that adjusted to fit the holes did not stay in place (nor was it very comforting to attempt trial and error to get them to fit). The instructions say that pushing them all the way to one end should be fine for LGA2011, but that was not the case for me. I attempted to put them in the holes in the case of either possibility for mounting, i.e., you can only mount a fan two different ways: one where it faces the front or back of the case, and another where it faces the top or bottom of the case. In either scenario, the brackets didn’t align properly to the holes.

I was able to force the brackets down slightly into the holes, but they did not actually hold the CPU in place. Instead, they were pushing on each side of the CPU so much, the CPU was slightly lifted out the the socket. That was terrifying to see and I immediately called off trying to mount this cooler.

Finally, this cooler continues the problem of using the “push-pin screws” for certain Intel socket types (not LGA2011, LGA1155 would be an example). THIS IS NOT SOMETHING THAT IS GOOD, JUST INCLUDE A BRACKET SO IT CAN BE FIRMLY ATTACHED TO THE BOARD.

Other Thoughts: I exhausted all of my personal possibilities in trying to give this cooler the benefit of the doubt, but nothing worked. I’m not going to try out this cooler on any more builds, especially builds that are not my own. I don’t trust this cooler at all.

Stay away from this Deepmax cooler, even for budget builds. There are significantly better coolers in the same budget range. This cooler just provides another reason for you to get one of those coolers instead; the alternative -- using this cooler -- could be a huge risk to the PC you’re excited about.

4 out of 5 eggsGreat Value for Performance

Pros: This CPU fan has exceeded my expectations. I compared it to the very popular ZALMAN CNPS9500 and found the DEEPCOOL fan to be better better overall. It is both cooler and quieter. The fins are more difficult to bend. The LEDs look nice. The design is simple.

Temperatures at both idle and under load dropped by 2C.

Because the fan is large (120mm), the fan does not need to run very fast to create a lot of wind. Where my old 92mm fan would go from 1500 to 2100 RPM under load, the DEEPCOOL unit only goes from 800 to 880 RPM in the same conditions. The 92mm fan noise would run at around 80dB under load, where the DEEPCOOL runs under 65dB.

It comes with thermal grease.

It comes with mounting hardware to install the fan to many CPU socket types.

The packaging worked perfectly; it was efficient, yet the parts felt secure.

The only moving part, the fan, can be easily replaced should it ever fail.

Cons: The clips which hold the fan to the heat sink are annoying. You must remove the fan to push the mounting clips into the motherboard holes. After mounting the heatsink to the motherboard, you have to remount the fan. This is when I found the clips to be annoying. Its just hard to figure out which way to orient them and how to hold everything together while you clip them. That said, I really appreciate that I can easily replace the fan later, and the clips make the fan mounting vertically adjustable. The clunky clips are worth the features they enable.

Other Thoughts: If you don't like the blue LEDs, you can easily replace this fan with one without LEDs or with a different color.
