Toshiba Satellite L300-11G

Beside Satellite A300 and P300 notebook series, Toshiba also released on market redesigned Satellite L series. We will introduce you with all novelties through testing of model Toshiba Satellite L300-11G. L series didn’t experience that much cosmetic changes like new A and P series did. We could even say that Satellite L300 is less “fancy” than its predecessor. Some of us will count that as big plus because L300 has above all “neutral” design. ...

 

ATi Radeon HD 4870 X2

Launch of nVIDIA’s GeForce GTX 280 brought a huge enthusiasm in last two months, but it already begun to fade. The main “culprit” is ATi which showed to all of us that even when hard times come they are continuing with good work as if competition isn't a problem and as confirmation of their efforts we got incredible new generation of graphics cards. The whole story started with great Radeon HD 4850 and continued with HD 4870 that had GDDR5 memory. After great critics for these two GPUs, ATi was aware that they shouldn’t stop there, if they want to overthrown nVIDIA from the top performance throne. And they did it… ...

ASUS Crosshair II Formula

Engineers from ASUS took into account every little detail while designing Crosshair II Formula motherboard and by taking a closer look at layout it is obvious that they didn’t economize with components integrated into this motherboard. This had big impact on final price tag for this motherboard but all this doesn’t guarantee that configuration based on this motherboard will work flawlessly and be able to satisfy needs of every overclocker out there. ...

 

Biostar A740G M2+

Biostar introduced “office version” of motherboard based on “office” AMD RS740 chipset. Graphics core is based on RV410, identical graphics core as for AMD RD690 chipset. DX10 is not supported, which isn’t a big problem because there isn’t any integrated graphics that can run DX10 games with decent framerate yet.     ...

What is common for all three CoolerMaster coolers on the test is that the motherboard needs to be removed from the computer case before installing the cooler itself. However, the setup itself is not too complicated, but simply requires reading the supplied manuals and some patience.

Eclipse cooler is different because it has a transverse fan (turbine), whereas HyperUC and GeminII have standard fans. A cross-shaped screwdriver is required for installing all three coolers.

 

In the GeminII packaging there is no fan, so the user must buy it himself. This cannot be taken as a drawback, considering its performance, while by choosing the fan carefully, you can make this ordinary cooler a silent one. HyperUC is a small, compact heatpipe cooler which doesn't require spacy cases, and is practically inaudible when at a small RPM rate, due to the unusual 9-fin construction. All three coolers have an enviable level of flatness, but better production could have given better gloss results.

 

HyperUC and Eclipse possess a 4-pin fan connector. HyperUC has 3 heatpipes, whereas the Eclipse has 4 of them, with GeminII going all the way up to 8! What is also worth mentioning is that GeminII keeps cool not only the processor, but also the entire motherboard by creating a sort of a typhoon, and the supplied sliders enable you to choose which part of the motherboard you wish to cool.

  

The plastic piece on top of Eclipse can be removed and moved in order to route hot air. Make sure your case can actually nest a GeminII, as it is truly a BIG cooler. Each of these coolers has a thermal paste bundled, which is certainly praiseworthy.
