5 out of 5 eggsThis thing rocks

This review is from: DEEPCOOL GAMMAXX 400 CPU Cooler 4 Heatpipes 120mm PWM Fan with Blue LED, Silver Award from HardwareSecret.com

Pros: Thermalpaste is always tricky but I applied it according to their directions by first tinting and then doing the dot method the size of a grain of rice, I was nervous at first because I always did the spread method but this thing keeps my CPU at a nice 34C stable temp even when taxed, very nice, played 3 hours of Starcraft and then Diablo straight and temp stayed at 34C

I also like the Blue LED's
It was also Easy to Install

Cons: None

This review is from: DEEPCOOL GAMMAXX 400 CPU Cooler 4 Heatpipes 120mm PWM Fan with Blue LED, Silver Award from HardwareSecret.com

Pros: Working for a month and it cools my CPU very well. The fan is very quiet. Blue LED lights up my case. Price! It's the best air cooler for the price,

Cons: It is big, measure your case before you buy it.

Other Thoughts: People say it is a pain for AMD installation. Well I think it is easy. Would buy again for another build.

5 out of 5 eggsIt's amazing!

This review is from: DEEPCOOL GAMMAXX 400 CPU Cooler 4 Heatpipes 120mm PWM Fan with Blue LED, Silver Award from HardwareSecret.com

Pros: Comes with 4 pin Led fan, cools my CPU effectively. The blue LED light isn't too bright, which i like, since the fan material isn't completely clear. Push pin mounting method makes Intel installation soo easy. Runs very quietly and blows plenty amount of air. the heatsink looks nice and sturdy. Overall It's an amazing product.

Cons: Great and no cons.

Other Thoughts: Would recommend it anyone

4 out of 5 eggsNot bad for the price

This review is from: DEEPCOOL GAMMAXX 400 CPU Cooler 4 Heatpipes 120mm PWM Fan with Blue LED, Silver Award from HardwareSecret.com

Pros: For the most part, the heatsink is well made (see cons for the not so good things).
The fan it comes with is quiet and does the job. The built-in LEDs are not overbearing or way too bright, so that’s nice. There are grooves in the heatsink where one could attach a second fan on the other side if they had a second set of brackets (the brackets seem like pretty standard wire clips from what I can tell and from comparing them to other units I have here) to hang it from.

The direct heatpipe design is pretty well executed with a few exceptions (see cons) but it did provide good contact to the top of the processor.

This is one of the few aftermarket coolers I’ve seen to use the standard AMD retention bracket. It is on the lighter side, so I don’t see it causing anyone too many issues.

Cooling performance is acceptable at stock speeds for the system I tested with. I didn’t dare overclock however, because I just didn’t have enough room. This heatsink would be great for the lower wattage CPUs for sure. With an AMD Phenom 955 BE clocked to a stock speed of 3.4 Ghz I saw idle temps of 32C (89.6F) and max load temps as high as 48C (118.4F) with about a 10 second return to idle temp after removing the load. I keep my house right around 21C (70F) so that isn’t too far above ambient.

I’d say, if you aren’t looking to overclock, and want a quiet, affordable cooler, this will fill that spot just fine.

The fan it comes with is a company branded 120mm model. Mine appears to be a hydro bearing as advertised and looks to be of decent quality. It also comes with a four-pin PWM plug.

attaching the appropriate mounting brackets is as simple as tightening four small screws.

The bracket for holding the fan on is your standard spring steel wire clips (seen on a lot of heatsinks) and they do the job just fine. That may not work if you are intending on installing a slimmer fan on this unit. Otherwise, they hold the fan on and are easy to remove for cleaning or fan replacement.

See other thoughts for system specs.

Cons: So the bottom of my heatsink was a little rough and required a bit of polishing and light sanding to get it smooth. Also, the entire surface was basically flat but milled slightly crooked.

It didn’t cause an issue with mounting and, looking at the footprint from the thermal grease, it seemed to touch the die of the processor just fine. The whole thing was just ever so slightly crooked when you set it on a table and examine the bottom.

The grease that comes with the heatsink is rubbish. spend the extra money and just grab some better thermal paste. I know this is a rule of thumb for a lot of people, but my packet was kind of dry and lumpy (no idea what that was about). I just used some metallic grease from a certain, well known, company.

The screws that hold the mounting brackets on are very tiny and easy to lose. I also almost stripped one of mine trying to thread it into the mounting hole. I’m guessing it had something to do with the threads in the hole being not quite right.

Other Thoughts: System: AMD Phenom II x4 955 Black Edition
ASRock 870 Extreme3 motherboard
8GB Corsair DDR3 RAM
2 X AMD Radeon HD 6800 Graphics cards

All tests for this carried out at stock speeds as I was not willing to push the system with this heatsink as I didn’t have a lot of thermal overhead left.


My overall opinion is that this is a decent product and it performs as expected. I did take one egg off for the less that stellar mounting surface and the crooked millwork.

4 out of 5 eggsWorks, with caveats

This review is from: DEEPCOOL GAMMAXX 400 CPU Cooler 4 Heatpipes 120mm PWM Fan with Blue LED, Silver Award from HardwareSecret.com

Pros: Cooling and noise levels were very good, as expected.

The fan was pretty tightly pre-mounted to the heat sink, so you won't have to fiddle around with that aspect of installation.

The fan uses a four-pin PWM connector, so your motherboard and/or fan control software can speed the fan up or slow it down as necessary. FYI, 3-pin PWM fan connectors give you a nice, loud, always 100%-power fan. Good for cooling, not so much for noise.

Blue LEDs on the fan are nice and bright. They'll definitely light your case up at night if that's what you're looking for.

Cons: Fairly poor packaging here. I've had this problem with other DEEPCOOL products. The interior of the retail box is divided into two parts.

This first interior part - the component box for all of the brackets, screws, etc. - is way too big for the parts, so they just move, rattle, and bounce around a lot. This wouldn't be too concerning except for the fact that the Intel push pins are plastic and could possibly break during transit. Mine were OK, but it still isn't ideal.

The second interior part is just an empty space occupied by the heat sink and fan. It's kinda sorta held in place by some cardboard cutouts, but not really. Mine came loose from the cutouts during transit and probably rocked back and forth a fair amount. No damage was noticeable, but, again, I'd like something packed nice & firmly in there.

I couldn't find any kind of sound dampeners between the cooling fan and heat sink. This means that any fan vibration will be passed directly to the heat sink, and you may hear that vibration during use. Believe me, nothing is more annoying than hearing your fan vibrate gently against the heat sink. I didn't notice anything during my few days with this unit so far, but only time will tell.

Also, and this is a big -1 for me, no instructions are provided other than some generic pictures on the back of the box. If you've never installed an aftermarket cooler before, do NOT start here. Seriously - stop reading about this product and look elsewhere right now. They don't even tell you how to install the weird squeeze pouch of cooling compound, and that's a pretty big deal.

Speaking of which - the non-name CPU paste is enclosed in some kind of weird, generic white squeeze pouch. This is the same pouch I've seen in every other DEEPCOOL cooler, and, for what it's worth, I wouldn't use it. Spend a few bucks and buy some Arctic Silver. Also make sure to read Arctic Silver's instructions on how to apply CPU paste since there aren't any instructions here.

Other Thoughts: For testing, I ran one of my desktop boxes (Intel Core i7-3770 CPU) at 100% CPU load for 6 hours with the cooler fan speed at 100%. Average temperature through the run was 62 Celsius (~144 Fahrenheit) according to CPUID's HWMonitor software. My Pyle PSPL03 decibel meter reported 46 dB for my entire desktop - this is about on par with that desktop's previously installed Noctua NH-U12 S.

Make sure this fits in your case. According to Newegg, this is 6.26" or about 159mm tall. Look at the specs for your case to see if it will accommodate a cooler of this height.

Also know that depending on your particular hardware, your CPU temperature and overall noise levels will be different than everybody else's. Take my numbers with a grain of salt.

This really is a no-frills el cheapo product that just barely has what you need and nothing else. If you already know what you're doing and just need the parts for an average after-market cooling solution at a low price, then this will fit the bill. If you're newer to aftermarket coolers and aren't real familiar with the pieces or how they work together, I'd avoid this product and instead choose something with better instructions.

5 out of 5 eggsbetter than cooler master sedon 120v

This review is from: DEEPCOOL GAMMAXX 400 CPU Cooler 4 Heatpipes 120mm PWM Fan with Blue LED, Silver Award from HardwareSecret.com

Pros: i used a push pull config for this. my G3258 was overclocked at 4.9 and idles at 28c. i bought this from a different site and it didn't come with extra brackets for a second fan. i emailed customer service and they gave a brand new cooler. HOW GREAT WAS THAT! EXCELLENT CUSTOMER SERVICE!

Cons: none

Other Thoughts: i interchanged my cpu cooler with a cooler master seidon 120v. the seidon idles at 31c, the gamaxx 400 idles at 28c. gaming, seidon @ 75c, gamaxx 400 72c. how can you explain this and i thought liquid cooling was better. just make sure you have headroom on your case as this is large. might take some space off your memory slots.

3 out of 5 eggsCould use improvement

This review is from: DEEPCOOL GAMMAXX 400 CPU Cooler 4 Heatpipes 120mm PWM Fan with Blue LED, Silver Award from HardwareSecret.com

Pros: Seems to cool my A10-7850k pretty well.

Cons: The clamp system needs to be the stock "cam lock, center pressure style". It is difficult and awkward to get this cooler attached. Also, it's difficult to get the thermal paste spread out well when attaching one side at a time. The clamp is very strong. I would recommend removing the mobo when installing.

Other Thoughts: A center force clamping style, like the stock cooler would make installation much easier. And insure good paste coverage.
