Arctic freezer 33 plus review in Spanish (full analysis)

These types of heatsinks have also evolved, even in their mid-range models. Evolution that we will be able to see perfectly reflected in the new Arctic Freezer 33 Plus, which with a price of 40 Euros, offers a series of very interesting features to mount a well-cooled mid-range system with very low noise at rest.

Technical characteristics of the Arctic Freezer 33 Plus

An evolution of the Freezer i32 +

Those of you who know the Arctic heatsink range a bit will have quickly recognized this new model as a direct evolution of the Freezer i32 Plus. Indeed it is and shares most of its benefits with it. They are practically identical and an Intel user surely would not notice a big difference between the two since it uses the same dissipation body and also the same fans.

The differences on this model is that now the Arctic Freezer 33 Plus adds support for AMD socket processors from AMD, when the previous model only supported Intel processors of the Kaby-Lake R range with socket LGA1151. In addition, the retention system has been modified to make it more robust and easy to mount.

They are slight improvements that will not make any owner of the Freezer i32 Plus change for this new model but it is good to know above all because it shows us the current importance that AMD processors have for all kinds of manufacturers of components and devices related to use PCs domestic.

The dissipation block

The Arctic Freezer range is very varied but the specialization of each model is usually more oriented to the type of fans, lighting, etc. Normally they use the same dissipation block for an entire generation, as in the case of the 33 or 32, but in this case the Plus model maintains the same dissipation body of the Freezer i32 Plus.

The heatsink of the Arctic Freezer 33 Plus is made up of a classic tower-shaped heatsink design with overlapping aluminum foils and communicated with each other using copper heatpipes. These heatpipes, a total of 4 with a diameter of 6mm, are in direct contact with the processor and run through the 49 aluminum sheets that form the dissipation block. They are also located in different areas of the radiator to maximize heat distribution and also to receive more air flow and therefore more dissipation capacity.

It has a completely symmetrical design which makes it especially suitable for systems that have memories in front and behind the processor, although in this model we can only find that situation in Intel LGA2011 and LGA2066 processors since it does not have support for socket TR4 systems for AMD Threadripper.

It has a height of 150 mm and is also capable of saving conventional size memories, although I cannot imagine any situation, in a modern motherboard, except perhaps some ITX models, where we could have problems since it has a very symmetrical design and with the fans issue we always find more flexibility when it comes to locating them.

With the help of the fans included in this model, Arctic affirms that it has a dissipation capacity of up to 320 W, but personally I would not trust this heatsink with a processor of more than 160w, with overclocking. By this I mean that it is a heatsink suitable for the medium ranges of Intel and AMD and that, if we are looking for a more capable solution, it is best to look at more powerful models.

Hybrid fans

With the Arctic Freezer 33 Plus we will find two fans that use an oil immersed bearing system. It is the umpteenth generation of these fans that Arctic uses and over time the system has been improved substantially. Thanks to the use of a calibrated double bearing system and the reinforcement of the bearing sleeve, less friction has been achieved, which reduces wear, increases life and also reduces noise.

The two 120mm fans have a 10-blade design and work with frequencies between 120 (passive mode is 0 rpm) and 1350rpm. The peak is contained allowing a maximum noise, per fan of about 30dBA. Connectivity includes adjustment via PWM and they also enjoy a passive ventilation system that keeps the fans completely stopped until we exceed a 40% pulse. This means that, if we have the right motherboard, and any modern motherboard is, we can have a complete stop on its fans when we have the computer in a state of reduced load, such as light tasks such as browsing, multimedia playback, etc.

The fixing system of the fans, by means of tensioning wires, achieves a uniform pressure on the blades and the design of the heatsink achieves more turbulence inside the blades and a more elaborate exit path that also draws more heat in its path.

Mounting system

The Arctic Freezer 33 Plus supports mounting to any modern or past processor except AMD socket TR4 processors. Its renewed anchoring system allows its use in LGA2011, LGA2066, AM4 socket processors, etc.

The system is by means of anchorage with back plate, taking advantage of the one of the own motherboard if it is an AM4 processor. Then it is enough to fix two screws depending on the necessary adapter and in 5 minutes we will have the heatsink in place and with the appropriate pressure to make it perform as efficiently as possible.

We have tried to mount it vertically, and although it is obviously more uncomfortable, it is also true that it can be done without too much trouble. We will only have to have some skill and, as is also usual, always with the fans removed since the fixing screw is at the same height as these. Putting the fans on and off won't be a problem either, even with the entire PC mounted as the tension wires sit sideways.

Performance and noise

TESTING BENCH
Processor:	Intel Core i7-8700K
Base plate:	Gigabyte Aorus Gaming K3
Memory:	GSKill DDR4 3000 16GB 2x8GB
Heatsink	Arctic Freezer 33 Plus
HDD	Samsung 960 EVO 512GB
Graphic card	Integrated processor
Power supply	Enermax 500w Fanless

We have tested this new model with a mid-range processor, but at the same time demanding, such as the Intel Core i7-8700K. We have tested it so much in its usual frequencies, always forcing the 6 cores it has, and also with a moderate overclocking of sustained 4.6GHz, which I think is perfectly acceptable for a heatsink like this, which in turn is quite economical.

These are our results:

Interesting results that show us that this model is more competitive than its price could initially indicate. The improvement of the fan, in this generation, achieves magnificent results of stability, noise and sustained temperatures, even more considering that our processor has not had any type of improvement to make it more efficient and that we have used, as always, the thermal paste which comes standard with the heatsink itself.

Hybrid ventilation for all audiences

The most interesting thing, without a doubt, about this model is that it continues the recent tradition of this range of offering a hybrid ventilation method that ensures a complete stop of the fans when they are not really needed. Our computer, for less than 40 Euros, will see your noise reduced substantially. An effect that we have been able to verify in action, working well with a mid-range processor, and that we can complement with a lot of similar components that are currently on the market, specifically graphics cards and sources, of very different prices.

Its dissipating performance is not bad, in view of our tests, but it is also nothing that we have not already seen in tower systems of similar size with “push-pull” fans at low or medium working frequencies. Its great virtue is that it offers us this completely passive mode on motherboards with PWM support.

Final words and conclusion about Arctic Freezer 33 Plus

The new Arctic Freezer 33 Plus is not the first generation of conventional Arctic hybrid heatsinks and the truth is that this generation does not offer great improvements but now they at least have support for AMD Ryzen socket AM4 processors that, as you well know, are now It is a more than solvent trend to achieve a powerful and versatile system with a more adjusted price and better availability than its Intel alternatives.

We recommend reading our guide on the best heatsinks on the market

As we have seen in our test bench it is capable of supporting the 4.6 GHz in all the i7-8700K cores. Having temperatures of 36 ºC at rest while at maximum performance it reaches 79 ºC.

In short, a good option to have hybrid ventilation, therefore low noise levels, and a very adequate cost of just under 40 Euros.

ADVANTAGE	DISADVANTAGES
+ Really balanced price	- We don't have support for TR4
+ Two good quality fans	- The hybrid system only works using it with four-contact PWM.
+ Quality materials and easy assembly
