The company Gelid Solutions present on the market of components and specializiruetsya mainly in the production of cooling systems and related products: thermoplast, fans and controllers. It is not surprising that the list of air coolers offered by the firm includes models of various designs and price ranges. Today we look at two new devices belonging to the middle class.
Gelid Tranquillo Rev. 4 – another reincarnation of the popular cooler with four heat pipes, which is familiar to our regular readers. It is made according to a classic tower scheme and is designed to fit 120 mm fan. One of the interesting features of this model it is possible to note the technology of direct contact heat pipes with the processor lid (and it is implemented is unusual, as will be discussed below) and the Nickel plating of the ribs. The recommended price of the novelty is $ 39.
Gelid Antarctica – a new model of higher level designed for installation of 140 mm fan. I wonder what the price of this cooler is not too different from its “younger brother” (the difference is only $ 3: 42 vs 39), but offers a large area of dispersion and an increased number of heat pipes. This product can already claim the title of supercooler, able to cool even overclocked the CPU with minimal noise.
Separately, I note that both cooling systems are equipped with high quality fans with hydrodynamic bearings and the possibility of PWM speed control. We will consider these models, evaluate design features, ease of installation and, of course, the cooling efficiency.
Both models Gelid supplied in cardboard boxes of medium size.
Accurate package size Gelid Tranquillo– 225 x 157 x 105 mm, Gelid Antarctica – 205 x 173 x 100 mm. simply put, they are very small, bought the cooler can be easily carried in almost any bag. Besides, the manufacturer has supplied the boxes handy plastic carrying handles.
Interestingly, the design of the packaging, Gelid two models were completely different, but the feedback in both cases – at a very high level. The manufacturer cites a detailed description of their products with several illustrations (to read the official descriptions, you can by clicking on the links – Antarctica,Tranquillo), table of characteristics and the list of supported platforms.
Inside both boxes was a blister of transparent plastic.
The fan on top of the radiator, on the other hand (also inside the box) is a cardboard box with fasteners and other elements of the package.
In conjunction with cardboard walls of the box plastic blister this is a fairly reliable protection for the cooler.However, when sending these devices in the mail I would recommend to spend money on extra tight pack.
Take a look at fastening systems, which include models Gelid Tranquillo Rev. 4…
… and Gelid Antarctica.
In both cases, the set includes a universal hard d-pad, mounting brackets, and a set of screws, nuts and springs to assemble the structure. It is easy to see that the retention system is almost identical. The only obvious difference is the shape of the brackets used when installing the cooler on AMD platform (Gelid Tranquillo are two separate trims, and Gelid Antarctica – a single frame).
The list of platforms on which you can install coolers, in both cases the same: Intel LGA 775, 115x, 1366 and AMD Socket AM2(+), AM3(+), FM1, FM2(+). It is gratifying that the manufacturer has not refused to support the classic connectors LGA 775 and LGA 1366, which are still widely used by many overclockers. But the lack of mounting for a more modern LGA 2011 is somewhat surprising. However, if necessary it can be purchased separately.
Both of the cooler is equipped with quality thermal paste Gelid GC-Pro. Separately, I note that the paste is not supplied in a disposable bag, and a syringe with a cap, which is enough for multiple installations.
Also included are installation instructions and additional brackets for a second fan (out of the box every cooler has only one fan).
So both the cooling Gelid enough securely Packed and equipped with everything necessary for installation and operation. Proceed to the visual inspection of radiators.
As noted above, we have a middle-class radiator with four heat pipes designed for installation of 120 mm fan.
Immediately, I note that the Nickel plating is all edges. With such (a dark “mirror”) coating, the cooler it looks neater and, perhaps, more than its rivals in the class. In my opinion, the manufacturer should have done silver and heat pipes. However, the contrasting combination of copper and Nickel also looks quite good.
The exact size of the radiator 154 x 62 x 128 mm. From the “average” models of tower layout (under 120 mm fan) product features Gelid somewhat greater thickness. 62 mm is a very respectable figure, I wonder if I can handle a single fan blowing such a “colossus” at low RPMs? However, the intercostal distance is quite large – about 2 mm, so the cooler has a really good job and for “swertia” modes.
Characteristic cutouts on the plates is a proprietary aerodynamic improvements designed to ensure more uniform air cooling fins over the entire area and possibly reduce the noise level.
Form of radiator engineers Gelid was really complex and beautiful – I wonder, what is more, engineering calculation or design ideas? Also note that TT are located in the body of the heat sink in a staggered fashion, which improves airflow and heat distribution on the plates.
The total number of edges – 39 pieces, the thickness is about 0.4 mm. the Estimated area of the radiator is slightly less than 5 000 cm2 (note that due to the complex shape of the plates, the accuracy of the calculations in this case are not too high).
This is a very respectable figure for “tower” heatsink middle class, although supercooler Gelid Tranquillo, of course, does not hold.
For the transfer of heat from the base to the fins meet four heat pipes of standard section (6 mm).Examining the contact points of the plates and tubes, signs of soldering could not be found (but the bends”collar” on the edges of the holes have, which should increase the area of contact).
Of particular interest is the design of the base. It is made by technology of direct contact of the tube come into direct contact with the processor cover (without additional heat-spreading plates).
By itself, this design is not new, but experts Gelid has offered an unusual implementation of known schemes. Tube touch each other without gaps: they are slightly tapered and turned – “in the plane”.
Thus, it appears that all of the base is the surface of TT. Needless to say, the contact is straighter than you can imagine. Treated “sole” very high quality: the print processor was extremely smooth. However, small gaps (less than 1 mm) between the tubes still remain – when installing the cooler they filled with thermal compound. The dimension of the base: ~ 27 x 34 mm.
On the reverse side is a large heat-spreading cap, soldered on the tube. It is made of aluminum and thick enough to provide heat transfer from the Central (most “loaded”) TT to the extreme.
To install the fan wire clips are used, allowing to adjust his position on height.
Best option, install the fan flush with the ends of the heat pipes, as shown in the photo. In this case, the frame does not increase the overall height of the structure. However, you can slightly lower or raise the turntable: the difference between extreme positions is about 20 mm. This way you can try to provide air cooling radiator VRM, or, conversely, to avoid “meeting” fan with high ridges on the RAM modules.
The total width of the structure after the mounting of the fan does not change – note that the sides of the vane at the edges there’s a kind of “bumpers”. As a negative point I will note that they interfere with the normal installation of the Gelid Tranquillo fan larger. However, the benefits of such a dubious replacement for the 140 mm “propeller” this radiator is still too small. The thickness of the design with a single fan size 120 x 25 mm is ~84 mm, with two ~106 mm.
Gelid Tranquillo Rev. 4 demetropolis equipped with a fan size 120 x 25 mm with marking A1212025S(L)-P. It looks very original thanks to the blades of unusual shape and contrasting combination of black frame and the white impeller. Backlight is missing.
Special notches at the base of each blade contribute to the redistribution of the air flow, reducing neoptolemou “dead zone” in the center.
The fan is equipped with a four-pin connector and supports PWM control. The range of speeds – 750-1600 rpm.
While at maximum speed, according to the manufacturer, the chopper provides a “flow” (flow rate) at the level 65.5 CFM (cubic feet per minute) and static pressure 2.18 mm of water column. The declared noise level ranges from 12.0 to 26.7 dB (conditions of measurement are not disclosed). The power cord is 500 mm.
The design uses a quiet and reliable hydrodynamic bearing. The stated time between failure is 50,000 hours.
The radiator of this cooler turned out to be bigger in height and width (and this is not surprising because it is designed for the installation of 140 mm fan), but somewhat thinner than Gelid Tranquillo.
Design size 140 x 49 x 160 () mm. In this case, Nickel was heat-pipe, but the fins are left without a cover (still wondering what is stopping Gelid to nicelybut their products entirely?). Externally, the radiator reminds me of a famous model of production of the same dimension (Archon, True Spirit 140).
The shape of the plates was much more simple than the older model, although some aerodynamic improvements is here. The edges of the plates protrude, and the center, by contrast, made the cut – this form allows you to more evenly distribute airflow over the entire area of the radiator.
Folds at the edges of the plates close the radiator from the sides so the stream passes right through him, not scattered to the sides.
Diameter of heat pipes is 6 mm. traces of soldering at the points of contact with edges are not seen. Heat pipes in this case are staggered. When looking at the radiator “full face” they lined up in a row without closing each other from the air stream.
In this picture is perfectly visible limb-“collar” on the edges of the holes, increasing the contact area between the tubes and plates. But the solder at the contact is absent, as the younger model. Wafer thickness is ~0.5 mm, and the intercostal distance is ~2.5 mm. This model should be well suited for working with a minimum blowing – in the most quiet modes. The estimated area of the radiator is about 5 400-5 500 cm2, which is slightly (~10%) more than the younger model.
When creating this version, the Gelid designers chose not to use the technology of direct contact. The base is made in the classic way – tube is sandwiched between two heat distribution plates grooves.
Some questions causes the processing quality of the base. Mirror finish is missing, moreover, to the naked eye visible traces of the grinding wheel. However, they have almost no tactile feel, and the imprint of the CPU on this basis it turns out extremely smooth.
The dimension of the base – 34 x 34 mm, its reverse side is a plate with grooves and powerful fins.
It was a real additional cooler with a decent area. The only thing that is unclear is why his ribs are oriented perpendicular to and not parallel to the air flow (and the same claim has already been expressed by the author of our laboratory to address other product Gelid GC – since then nothing has changed).
For mounting the fan again used the wire clamps, allowing you to adjust the height it is installed. The standard version is the same – a fan frame is exposed flush with the ends of the heat pipes, but the fan can just be left out (for better airflow additional radiator and okolomatocnah space) or raise (to improve compatibility).
The total width of the structure with the installation of turntables is not changed, the thickness of the single “propeller” size 140 x 25 mm is 74 mm, with two – 99 mm.
This radiator comes with a fan size 140 x 25 mm, marked as Gelid Antarctica Silent 14 PWM. And the impeller, the fan frame is made of black plastic, no lights.
The shape of the impeller can be called traditional – there are no aerodynamic innovations, the average width of the blades indicates that we have before us a balanced model with the average “flow” (flow) and static pressure.
The manufacturer claims the following figures: consumption 137 CFM (cubic feet per minute), static pressure – 1.86 mm of water column at maximum speed.
Note the location of the mounting holes. Thanks to the frame of the special shape of the fan can be installed on the seat of the ordinary “stadmadrid” (similar scheme used by many manufacturers, I can remember Zalman, Noctua and its).
The fan is equipped with a four-pin power connector and supports PWM adjustment. The claimed range of speeds – from 450 to 1500 rpm while the noise level up to 27.8 dB (conditions of measurement are not specified again).
The design uses a hydrodynamic bearing, characterized by extremely high reliability. The stated time between failure is 50,000 hours (the Junior model). The length of the cord is ~350 mm.
We have already mentioned that the fastening system two Gelid coolers were virtually identical. Setting Gelid Antarctica and Gelid Tranquillo Rev. 4 is exactly the same, so we will consider it on the example of the second cooler.
The following describes the process of installation of radiators on the platform Intel LGA 115х. For other supported connectors the sequence of actions is the same, the only difference is the position of the screws in the eyelets of the mounting brackets and “backplate”.
The installation in both cases you should start with the installation of suitable mounting brackets on the base of the cooler. For all Intel platforms apply universal curved brackets. For fixing you should use the smallest screws supplied.
Next step is to install the hard d-pad. The easiest way to do this, turn over the motherboard. However, even in this case, you expect some inconvenience. The screws did not hold their ground, they spin freely and aim to pop up. So you can’t just flip the motherboard to its normal position and continue Assembly.
Nuts have blind turns holding each screw with your finger.
With the front side of the Board, the crosspiece is fixed by means of nuts with notches.
Next, you need to take the screws with internal thread and put on their springs.
And again I note the accompanying inconvenience – spring is not fixed so that by tightening these screws, you will also have to demonstrate dexterity and patience (however, Gelid Antarctica with this somewhat better springs to put on “interference”).
Then on top of the CPU apply thermal paste, the screws pull the whole design together, fixing the radiator. This procedure is completed – the installation is simple, subject to all items of the user to cope with it even the person with minimal experience in assembling computers.
The total height of the Gelid Tranquillo Rev. 4 when measuring from the surface of the Board is 158 mm. Distance from the PCB to the bottom fin of the radiator 42 mm, the distance to the frame of the fan (when installing it flush with the ends of the heat pipes) is about 30 mm. Lifting the turntable, it can be increased up to ~38-40 mm.
The same measurements were performed for Gelid Antarctica. Full design height when measured from the surface of the PCB – 164 mm, the distance to the bottom edge of the radiator 42 mm to the framework of fan is ~28 mm (can be increased up to ~38 mm).
I note that both of the cooler was “wading” – the fins and the base shares a decent distance (not less than 40 mm), which will easily fit radiators VRM motherboards.
The height of Gelid Antarctica and Gelid Tranquillo typical for cooling tower layout (under 140 mm and 120 mm fans), so they easily accommodate almost any standard “high tower”. To be vigilant and to perform additional measurements before you buy should be, first and foremost, the owners of compact cases.
The fastening system proposed Gelid provides a fairly strong clip, looks durable and reliable. But the ease of installation deserves high evaluation of “satisfactory”.
Rivals for Gelid products are long present on the market and are familiar to most readers radiators tower layout.
A direct competitor to the Gelid Tranquillo Rev. 4 is its True Spirit 120.
One of the most famous coolers this dimension, even in its appearance, was something like his “counterpart”. The design also uses four heat pipes, radiators close in size and area of the dispersion.
The model of the Zalman CNPS11X Performa.
Unusual cooling system the middle class is compact, the design uses four heat pipes.
These supercooler in this collection there (after all, we consider the products of the middle class), and as “heavy artillery” is widely known for Ice Hammer IH-4500 with a large dispersion area and five thick (8mm) heat pipes.
The base of this cooler also made by technology of direct contact.
Processor test stand (Intel Core i5-2500K) was overclocked to 4500 MHz by increasing the multiplier to 45 units. This value can be considered typical for this CPU, so overclocking is most often used by overclockers in the “24/7”. It is known that the CPU can operate at the specified frequency at a voltage of 1.36 V, but I deliberately used a higher value – 1.4 In exactly to increase heat dissipation.
Overclocking Intel Core i5-2500K was conducted without the use of additional tools change the settings in the BIOS Setup. RAM worked in a regular mode X. M. P. (1600 MHz, 7-7-7-20-2T). The graphics card is operated on standard frequencies.
To heat the CPU to use a traditional test in Linpack LinX shell version 0.6.5 (four threads, the memory 2560 MB 15 runs). It should be noted that Linpack provides an extremely high load, so the resulting temperatures are markedly superior to “everyday” figures that can be obtained even with prolonged use of all CPU cores.
The graphs in all cases, the indicated temperature of the hottest core. Monitoring of fan speed and CPU temperature was carried out using utilities 4.47 Speed Fan and Real Temp 3.60.
The noise level was measured using a digital sound level meter Becool sun-8922 with the measurement error not more than 0.5 dB. The measurements were carried out with a distance of 1 m. the Level of background noise in the room – no more than 26.5-27.0 dB. The temperature of the air in the room was 24-25 degrees Celsius.
Despite significant differences in the design of radiators a list of “pros” and “cons” of the two Gelid products were exactly the same, so they decided to combine into one list.
So, in joining the PSU Gelid was announced as the device of the middle class. They turned out well.
Both cooler successfully cope with cooling the overclocked processor, however, do not allow ultimately “strangle” the fans. In this respect, it is preferable looks Gelid Antarctica– the benefits of a radiator are disclosed in quiet modes. At an average speed of rotation of the impellers, the difference between the two models is very small. However, the same applies to the cost.
Gelid Antarctica and Gelid Tranquillo equipped with a reliable fan with hydrodynamic bearings and are supplied with quality thermal compound. Thus, the choice between the two models is dictated mainly by the interoperability (Gelid Antarctica is more high) and availability (Gelid Tranquillo is more widely represented in the sale).
