Their main goal is to maintain customer satisfaction by serving our customer’s ever-changing thermal needs and providing the quickest and most comprehensive service available.

Today, we’ll have a look at DeepCool’s budget oriented yet great performing CPU Cooler – DeepCool Ice Matrix 400. The ‘4’ in the name refers to the 4 heatpipes used in this cooler. It also comes in 6 heatpipe flavor which is known as Ice Matrix 600.

Packaging and Contents:

DeepCool Ice Matrix 400 comes in a not-so-big box with DeepCool’s signature white and blue theme. Front of the box gives a nice look of the heatsink itself.


Other sides have those traditional specifications in a number of different languages.

Moving towards the actual thing, the Ice Matrix 400 cooler isn’t that big. Its overall dimensions are 130X73.5X160mm. The actual heatsink area is even smaller than a standard 120mm fan.
Even with this small this it was a little over 1KG with fan mounted i.e. 1030g, that’s a bit on the higher side.



It features 46 aluminum platted fins that are pressed onto 4 6mm cooper heatpipes. Heatpipes go in a “U” shaped pattern like most of the tower coolers.


To keep the width of the cooler at lower possible value heatpipes are arranged in a really weird manner at the place they meet the base. In fins, they are arranged in a straight line to improve air flow through the heatsink and maximize cooling performance.

Ice Matrix 400 features a extremely flat nickel plated cooper base. It has this ‘remove before installation’ warning on it.


DeepCool Ice Matrix 400 comes with a 120mm PWN fan with TPE cover. This exclusive TPE cover is this plastic thing which covers the entire surface of fan’s frame. This helps in absorbing operating vibration and noise. Fan operates at fan speed ranging from 500RPM to 1500RPM producing 66.3CFM. Speed of the fan is controlled by PWM signal. At 1500RPM it produces noise of 27.6 dBA.

Accessories and Installation:

DeepCool is generous enough to include each and everything you need or you’ll ever need in the lifetime of this cooler. It comes with mounting mechanism of pretty much every Intel and AMD socket available out in the market that includes LGA1155/1156, LGA1366 and LGA775 from Intel side, AM2, AM2+ and AM3 from AMD side.

It also comes two sets of fan clips to mount 2 fans for even better performance. Other than that, it comes with 3-pin Y-cable, Molex to 3-pin convertor and 3-pin to Molex convertor. DeepCool also included a quarter filled small syringe of thermal paste. I really didn’t like its quality.

Installing this cooler requires you to take the motherboard out of case but it’s an extremely straight forward procedure. The included manual is really handy, it explains everything nicely. You need to install the new back plate. After that just install the screw threads, and the insulation washers, fit the appropriate retention plates on the cooler, apply the thermal compound and the finally place and screw in the cooler.

Test and Results:

All tests were done in same environment with same ambient temps. Load temperatures were recorded after loading the CPU for 15mins.

Test System:

  • Core i7 870 @ 4.0GHz (1.4v)
  • ASUS P7H55-V
  • Kingston DDR3 1333MHz 4GB
  • HIS Radeon 4670
  • Xigmatek 600w PSU
  • Cooler Master CM690-II
  • Seagate 7200.12 500GB HDD


DeepCool Ice Matrix 400 is a great cooler but it’s not the best. Actually, it’s not designed to be the best. It is designed for budget oriented users and it’s pretty good at it.

Ice Matrix 400 retails for around 40USD and it performs pretty well in its price sector. Apart from performance it looks good too. It comes with a lot of accessories which is very surprising in such a small price tag and we shouldn’t forget the included 120mm TPE covered fan.

All in all it’s a great cooler even if you are going to slightly overclock your system or you are just looking to change your stock cooler for something more powerful and good looking.
