The budgetary cooler is cheaper than dollars? Easily! Apparently, so the main marketing slogan in sector of systems of cooling for platforms AMD Socket 754/9 this spring sounds. Really, price rod for last months it is significant has lowered: hitherto the indestructible budgetary bastion (a level of dollars) has given a distinct crack, and considerable number of models have smoothly moved down in much more tempting segment of 6- dollars, and separate stroptivcy' even have managed to overcome the important psychological boundary in dollars. Certainly, in many respects these tendencies were defined by rather aggressive dumping from distributors a market competition, let and not always extremely transparent, for the present nobody cancelled. But quite objective reasons, in fact coolers of a budgetary category, unlike the hay-e`ndovy'h colleagues took place also, usually are not hi-tech production (last is naturally interfaced to serious centrino intel notebook industrial expenses) and always offer a wide field for price maneuvers. Therefore, to leading distributors was only a little poumerit' own appetites enough to allow economic models real chance to become truly attractive by way of retail cost. And there and before formation new, especially malobyudjetnogo a class of coolers already absolutely nearby!
In any case what were sermyajny'e preconditions to an establishment of noted market situation, we as the consumers, similar negative dynamics of displacement of the prices we can greet only if only functionality and quality of new economic products has not pumped up. To clear this moment, in focus of our test tests of dozen actual coolers of a budgetary category in cost up to dollars the model from ASUS, models from Cooler Master, models from GlacialTech and models from Titan today is located. Well, we shall start their inspection!
Opens our review budgetary individualist from grocery ruler ASUS centrino intel notebook Crux K MH7S. The cooler is based on an aluminium radiator mm with rather zanyatny'm radial orebreniem, is equipped by the fan of a standard size mm and seasoned by fixing system bezotvertochnoy configurations.
As a matter of fact, Crux K MH7S is reincarnation of models, adopting from predecessors the basic ideological features and supplementing new technical konstruktiv corresponding adaptation under Socket 754/939: the original configuration orebreniya a radiator remains almost untouched, finding out little bit truncated dimensions (it is had all the same advanced radial swastika with an edge trapeceidal'nogo sections thickness of 0, mm in the basis and 0, mm at top, a total area of a surface of heat exchange of 14 sm 2), and zapressovanny'y the copper core of diameter of mm represents itself as centrino intel notebook thermal bonifikatora, facilitating redistribution of a thermal stream in a working body of a cooler.
It is not bad looked Crux K MH7S and by way of operational properties the cooler possesses quite decent fixing system (pair fixing klips and rotary levers) which, let and differs some technical complexity, but allows accurately and without special efforts to mount a radiator in a socket. An additional chesspiece of the state employee from ASUS becomes the scheme termokontrolya, built in in nabortny'y the fan (model AVC DE U) speed of rotation kry'l'chatki varies from 22 up to 60 rev/min in a range of ambient temperatures 25- C (that is, mechanisms termoregulirovki actually repeat, characteristic for boksovy'h coolers AMD).
As if to pure practice our ward, despite of the developed maintenance, all the same disappoints more, than inspires. In the typical intracase conditions modelled by the test stand (the temperature of environment C), Crux K centrino intel notebook MH7S shows excellent thermal parameters, changing many budgetary contenders, and comes nearer to products of higher class. However it is reached the expensive by a level of noise made by it to name ergonomic it is possible only with very big stretch (high turns kry'l'chatki the fan affect, 48 rev/min numbering the order). As the result, cumulative functionality of a cooler appears impaired a little, and as a result to extend up to attractive values balancing e`ffektivnost'-shum to it and it is not possible.
Further two state employees appear in our list from Cooler Master models CK8-8JD2B- and DK8-8I32A-99. These coolers are based on an aluminium radiator mm with lamellar orebreniem similar konstruktiva, are equipped by fans of a standard size mm and equipped bezotvertochnoy by fixing system.
Technically CK8-8JD2B- appears, being expressed figuratively, the native brother of coolers: all these three products belong to centrino intel notebook one series, possess completely an identical radiator which is improved krupnorazmerny'm by a copper disk 44h mm, zapressovanny'm in a sole, and are seasoned by identical fixture. Unique distinction between them is hidden in equipment nabortnogo the fan at mal'ca CK8-8JD2B- it is strongly simplified (read, it is extremely minimized in cost and quality), naking typical, not too optimum configuration kry'l'chatki together with very hilen'kim the bearing of sliding.
Other state employee from family Cooler Master DK8-8I32A-99, is even more hard-fisted updating of coolers of series CK8-8JD2B for the company with the facilitated fan similar to model CK8-8JD2B-99, it receives already cleanly aluminium radiator deprived of a copper insert. However all the other family features peculiar to series CK8-8JD2B, remain on centrino intel notebook the places: as significant technical help, simple and convenient well proved fixing system again serves in the installation, essential operational plus also becomes preestablished termointerfeys highly effective termopasta on the basis of a composition oksida and nitride of aluminium.
Pamyatuya about former successes CK8-8JD2B-0L and CK8-8JD2B-01, we expected to see equivalent productivity and in a track record of model CK8-8JD2B-99, the blessing thermal konstruktiv at them is identical. In general, practice has fixed our positive spirit a cooler really shows quite worthy parameters of thermal efficiency and differs the moderate noise. Though, business all the same has not done without the certain clauses: despite of authenticity medno-alyuminievogo a radiator centrino intel notebook and similar high-speed characteristics of the fan (nominal turns 26 rev/min), CK8-8JD2B- on the fact concede to colleague CK8-8JD2B-0L and in thermal parameters, and especially in the ratio e`ffektivnost'-shum (it is obvious, such rasklad takes place to be just because of less productive fan).
And here state employee DK8-8I32A-99, alas, to distinguish attractive productivity the configuration orebreniya together with tihohodny'm any more (nominal turns 22 rev/min) cannot prostovataya and the unproductive fan does not leave to it practically any chances of adequately to show. As a result, by thermal efficiency the cooler strongly loses related models from Cooler Master, and in the ratio e`ffektivnost'-shum looks not the best image.
GlacialTech Igloo 72 Silent, Igloo 72 Light and Igloo 72
Three beginners from budgetary family of products GlacialTech Igloo 72 Silent, Igloo 72 Light and Igloo centrino intel notebook 72 continue today's test-list. These coolers are based on a compact aluminium radiator mm, are equipped by fans of a standard size mm and it is traditional otranjirovany' on speed of rotation kry'l'chatki (nominal 2200, 26 and 32 rev/min).
GlacialTech Igloo 72 Silent and GlacialTech Igloo 72 Light
New series Igloo 72 in many respects repeats a maintenance of the predecessors of deserved hard workers Igloo 7200, however updatings carry here not so much ideological, how many cleanly quantitative character, and rather economical sense. Apparently, main as now it is accepted to speak, messedj updated state employees GlacialTech it is necessity to present the decision facilitated at cost, but at the same time, carefully to keep or even in something centrino intel notebook to increase greatly all functional the charm, present at heavier veterans of former series.
GlacialTech Igloo 72 Pro and GlacialTech Igloo 72 Silent
Following the ideology traditional for ruler Igloo, konstruktiv radiator Igloo 72 receives catalysts of thermal efficiency well familiar to us an edge trapeceidal'nogo sections and alternation of height of an edge (symbiosis of these tools is aimed at increase of thermal and hydraulic efficiency orebreniya), but already with more hi-tech parameters orebreniya (thickness of an edge of 0, mm in the basis and 0, mm at top) and more rational redistribution of thermal loading ( effectively working edges against at Igloo 7200). As the result, despite of grown thin rather Igloo centrino intel notebook 72 overall dimensions, Igloo 72 gets the same developed area of a surface of heat exchange (the order of 15 sm 2), and its weight, in view of the fan of the facilitated standard size, becomes almost that microscopic (3 g against 3 g at Igloo 7200).
State employees Igloo 72 will not be in debt and in connection with operational properties, diligently repeating 72 fixing system passes ergonomics Igloo to beginners practically without changes (are present small konstruktivno-kosmeticheskie completions), and with the same friendliness to the user provides easy and extremely fast landing a cooler in a socket. On the put place settles down and preestablished termointerfeys highly effective termopasta (napolnitel' a composition oksida and nitride of aluminium), possessing advanced teplofizicheskimi in parameters.
By way of thermal and centrino intel notebook shumovy'h parameters modelling number Igloo 72 is looked too very not bad. Foreman Igloo 72 cooler practically on equal achieves the most interesting productivity argues with products of heavier class (in particular, successfully competes to strong enough athletes Thermaltake TR M and Cooler Master CK8-8JD2B-99, catching up hay-e`dovy'y Zalman CNPS7700-Cu, functioning in mode Silent Mode), thus it shumovy'e characteristics are maintained at moderate and quite ergonomic level. Well copes with a task in view and serednyak Igloo 72 Light which notably advances veteran Igloo 72 Light and shows more than a worthy parity e`ffektivnost'-shum. The younger representative of a series tihonya Igloo 72 Silent, operates any more so harmoniously and on thermal parameters seriously concedes to the colleagues. Those not less, in cumulative functionality and it looks quite decently, due to truly ergonomic shumovy'h characteristics.
Now at us on turn to consideration appears centrino intel notebook coolers TTC-K8ETB/8 and TTC-K8DTB/925, base elements in a modern budgetary ruler of systems of cooling under Socket 754/9 from Titan.
On the grade state employee TTC-K8ETB/8 especial is not allocated aluminium radiator mm with anything has in an active (a sole 78h the mm), is equipped by the fan of a standard size mm with rated speed of rotation kry'l'chatki 28 rev/min and seasoned bezotvertochnoy by fixing system (which, to a word, it is rather practical and convenient). It is possible to note still electrochemical polishing of a surface of a radiator together with a bright protective lattice on the fan, however abundantly clear, that it in a greater measure elements ukrashatel'stva, than cleanly practical details.
Really positive technical moment in konstruktive TTC-K8ETB/8 is the combination of two known bonifikatorov edges centrino intel notebook trapeceidal'nogo sections and alternations of height of an edge which improve thermal properties of a radiator. However, unfortunately, the general outline of their application leaves much to be desired parameters actually most orebreniya in practice appear rather prostovaty'mi (average thickness of 1, mm in the basis and 0, mm at top, a step of an edge of 1, mm), and the area of a surface of heat exchange hardly holds out up to 9 sm (size it is significant smaller, than at other state employees).
As a result, having hilovatoy technical equipment, TTC-K8ETB/8 in actual fact shows naturally weak productivity concedes on thermal parameters to many contenders of a budgetary class (let alone more advanced centrino intel notebook coolers) and enough osch'utimo rustles, rolling down actually in the bottoms of a today's rating on a parity e`ffektivnost'-shum.
Another titanovskiy state employee TTC-K8DTB/925, looks already much more representative product this cooler is based on a large-sized aluminium radiator mm (a sole 67h the mm) with zanyatnoy a configuration orebreniya, is equipped by the fan of a standard size mm with rated speed of rotation kry'l'chatki 24 rev/min and flavoured bezotvertochnoy fixing klipsoy (similar model TTC-K8ETB/825).
Sight TTC-K8DTB/9 is the advanced ideology of its working body: instead of typical lamellar structure, orebrenie it is generated here H-obraznoy bearing with radial branches. At the accurate engineering approach such decision allows to optimize thermal characteristics and to improve produvaemost' a radiator, but besides, as well as in case of with TTC-K8ETB/825, practical realization promising zadumki appears on behalf of TTC-K8DTB/9 far not the centrino intel notebook best parameters orebreniya again extremely weak (an edge of rectangular section, average thickness of mm, a step of an edge of mm), and the effective area of a surface of heat exchange totals the little more than 8 sm (up to a disgrace small size if to consider overall dimensions of a cooler).
As result, our ward let also advances colleague TTC-K8ETB/8 in test running, advantage turns out insignificant TTC-K8DTB/9 still shows not the highest thermal parameters, and in shumovy'h characteristics gromkovat, that as a result does not allow it to prove well in cumulative functionality.
Finish a today's review coolers DC-K8D925Z and DC-K8A825Z from brand Data Cooler of especially economic trade mark, prodyusiruemoy Titan.
State employee DC-K8D925Z in the marketing attitude is the reduced the price alternative of model TTC-K8DTB/9 a cooler is based on a large-sized aluminium radiator centrino intel notebook mm (a sole 65h mm), but already with less pretentious configuration orebreniya, is equipped by the fan of a standard size mm with rated speed of rotation kry'l'chatki 22 rev/min (konstruktiv which also it is simplified have the bearing of sliding instead of a combination of the bearing kacheniya and the bearing of sliding at TTC-K8DTB/925) and seasoned bezotvertochny'm by fixture.
Meanwhile, the situation around DC-K8D925Z turns out, we shall directly tell, paradoxical being simplified under the form, it possesses the thermal maintenance, is significant surpassing stuffing TTC-K8DTB/925: the radiator shows quite worthy parameters (an edge trapeceidal'nogo sections, thickness in the basis of 0, mm and 0, mm at top, a step of an edge of mm), the improved hydraulics orebreniya and the developed surface of heat exchange (a total area of the order centrino intel notebook of 13 sm 2), forming together with nabortny'm the full-sized fan well coordinated tandem.
It is pleasant, that DC-K8D925Z does not miss chance to take advantage of the deposits and it gives out on mountain rather interesting productivity successfully competes by thermal efficiency to products of heavier class (in particular, goes level with advanced Thermaltake TR M14), supplementing worthy thermal parameters the moderate noise. However, to the great regret, one serious minus here all the same emerges the general kind picture fairly spoils technical quality nabortnogo the fan, both in the mechanic and in which electrician of business are far not in the best image.
As if to other state employee from family Data Cooler DC-K8A825Z this product appears as already reduced the price assistant to related model TTC-K8ETB/8 a cooler is based on an identical radiator mm, it is equipped by absolutely similar fixture and it is seasoned centrino intel notebook by the fan of a standard size mm with strongly simplified technical equipment.
Gawk DC-K8A825Z in actual fact is practically authentic copy TTC-K8ETB/8 all constructive features here remain on the places. There are no special differences between these coolers and in cumulative functionality on thermal parameters DC-K8A825Z moves level with with the primogenitor, showing small advantage in the ratio e`ffektivnost'-shum due to more ergonomic shumovy'h characteristics. At the same time, quality nabortnogo the fan at DC-K8A825Z, as well as in case of with DC-K8D925Z, again appears not too sound, that as a result belittles image of this cooler rather purely brendovogo centrino intel notebook TTC-K8ETB/825.
So, the coolers planned for today proinspektirovany', and oznakomitel'no-obzornuyu a part of our research it is possible to consider all successfully completed. It is time to address to results of test tests!
For research of thermal efficiency of examinees of coolers Socket 754/9 on arms the same methodological principles that find the application in our tests of systems of cooling for platforms Socket 4 and LGA7 are accepted. As primary data of a basis for the subsequent definition of thermal resistance, temperature parameters built in termodioda the processor here act, the thermal source (now it is processor Athlon 37 +), a basic platform (parent payment Fujitsu-Siemens D1607) and a set of the test software only varies.
For modelling thermal loading of the processor close to maximal, test utility S M is used, and firm utility SystemGuard is applied to monitoring temperature parameters from Fujitsu-Siemens.
ja = (T j T centrino intel notebook a)/P h, where T j temperature of a processor kernel, T a an ambient temperature (in our case makes C), P h thermal capacity of the processor (in our case this parameter makes Vt).
At last, in end of this section we result results of measurements of noise (about a technique read in clause), and also a rating on raschitanny'm to sizes of a parity e`ffektivnost'/shum.
SE`SH = RM * (OP t/TO) / (USH/OP), where OP te` a thermal basic parameter
(Reference thermal resistance ja systems of cooling - 0, C/Vt), TP temperature
Kernels c use of considered system of cooling, OP sh shumovoy a basic parameter
(Reference noise level - dBA), USH the noise level, cooling made by system, RM dimensional
Most likely, any additional comments here any more it is not required. We shall sum up!
The considered coolers successfully cope with our promotion examination and within centrino intel notebook the limits of those requirements which are usually shown to products of a budgetary class, feel quite comfortably. Especially it would be desirable to note today models GlacialTech Igloo 72 and Igloo 72 Light these coolers possess perfectly balanced set of technical qualities and can provide a comprehensible thermal mode even topovy'm dvuyaderny'm to processors AMD. The steadfast attention is deserved also with model Cooler Master CK8-8JD2B- which shows attractive functionality, combining high thermal efficiency with worthy shumovoy ergonomics.
Well, and if as the main priority at a choice of a cooler there is its profitability, in this case it is possible to look narrowly centrino intel notebook at models Cooler Master DK8-8I32A- and Data Cooler DC-K8A825Z exclusively low price is capable to move practically all of them technical lacks.
