Install l775 cooler

Technical parameters of the finning are also quite decent: the heatsink comprises eighty four 0. The CIHDPA-0L and CIHDPA models are practically identical to the boxed cooler as far as their operation is concerned: the heatsink is installed with special plastic clips to be pushed though the mounting holes on a motherboard, with all pros and cons of this installation installation and deinstallation convenience is an advantage, but the cooler is not very tight in the socket.

Preinstalled thermal interface is an additional advantage, quite of decent quality at that thermal-transfer filling agent is a composition of silicon oxide and boron nitride. These coolers also look good in terms of thermal efficiency, they compete well with the copper-aluminum boxed modification: the CIHDPA model nominal rotational speed - rpm is practically on a par with the boxed cooler, but demonstrates a significantly lower noise level.

The other model — CIHDPA-0L nominal rotational speed - rpm is not a jot worse than a placated boxed model, it's even more ergonomic in terms of noise, shooting ahead in the efficiency-noise ratio. The updated models have ideologically the same heatsink with a copper core. They are equipped with similar 92x25 mm fans with the rotational speed of , , and rpm.

But at the same time they introduce a number of additions and improvements e. Compared to the reference design, this installation method is certainly less convenient — you will have to take a lot of trouble over its installation. But in technical terms, this retention mechanism helps the CIJD3A sit really tight in a socket with reinforced and optimized hold-down pressure, thus ensuring better quality of the thermal contact between the heatsink and a processor.

Although the new finning is simplified rather than improved 72 fins, their average thickness is 0. The best results are shown by the CIJD3A model — this cooler outperforms the boxed modification in thermal efficiency, demonstrating much more ergonomic noise characteristics. The CIJD3A-0L looks very good, demonstrating a really low and ergonomic noise level together with decent thermal characteristics.

The CIJD3A-PL model also shows decent results, but it sways to and fro — the cooler is not much more thermally efficient than the CIJD3A, but it demonstrates excessive energy in terms of noise characteristics, almost reaching the critical 50 dBA. The rotational speed of rpm is excessive here, it causes an undesirable air flow recirculation and hampers the reduction of thermal resistance of the cooler.

These coolers are based on the aluminum 90x90x48 mm heatsink. They are equipped with 90x90x25 mm fans, traditionally ranking in the rotational speed , , , and rpm correspondingly. The PWM model is additionally equipped with a rotational speed control circuit the speed is varied from to rpm by system monitoring of the motherboard.

GlacialTech Igloo and Igloo PWM Igloo is essentially a product of development overhauling is a better word here of technical ideas, implemented in the previous models from the Igloo series, both in cosmetic the new coolers look more attractive as well as in purely technical terms. The main acquisition here is a much more developed configuration with denser finning, larded with traditional catalysts of heat efficiency - tapered section fins 0.

The heatsink base was also improved — it got a special 60x32x5 mm cut-out, which allowed to optimize channeling the heat from a processor without wave-like bulges and make the heatsink more compact. Thus, due to the improved finning parameters, Igloo heatsink grew the total area of the heat exchange surface to cm 2 versus cm 2 in Igloo But the cooler did not become heavier, it even got lighter by nearly g g versus g in Igloo Other technical characteristics of Igloo which proved themselves worthy even in the Igloo series remained practically unchanged: the retention bracket with screws was insignificantly overhauled, in order to adapt to the new construction of the heatsink base; the fans retained their authenticity — dimensions and the grid pipe, converging in the airflow direction; the preinstalled thermal interface of a good quality is also there filling agent — a composition of aluminum nitride and oxide.

Speaking in terms of pure practice, the complex of changes fits Igloo very well and charges it up — all models of the new series demonstrate optimized thermal characteristics versus Igloo In terms of thermal efficiency, Igloo PWM rpm expectedly takes up the lead — this cooler outperforms the robust competitor from Cooler Master — CIJD3A-PL, leaves far behind the boxed model, and comes close to results of higher-classed products.

But this victory comes at a great cost, it does not look that peachy in noise terms — a tad lower than the critical mark of 50 dBA. Igloo and Igloo Light are more unassuming, but look much more attractive in total functionality than their senior brother — they compete well with the boxed cooler and its clones, demonstrating an ergonomically bearable noise level.

Igloo Silent is the most interesting in this series: it shows decent thermal results and breaks a peculiar budget record — the best efficiency-noise ratio among the budget models we reviewed! To all appearances, Igloo is adapted to low-power air flow and correspondingly low-noise fans.

This solution is quite expedient, as the main task now is to maximize thermal efficiency and simultaneously minimize the noise. As you can see, Igloo copes with this task well.
