In recent years, the domestic consumer notebook gaming performance of the increasingly high demand, forcing the mainstream notebook manufacturers continue to upgrade the video card configuration, but by the size and cost constraints, the drawbacks of large high-performance graphics card heat gradually exposed as risks affecting the stability of notebook work. So we buy this type of gaming notebook, the study should focus on its cooling effect.
Order to Competition for high-end independent video card notes notebook market with Lenovo Y470, Acer 4830TG , Hewlett-Packard recently introduced a new dv4 series laptop, which uses HD 6750 discrete graphics, and popular HD 5650 compared to last year, more on game performance floor. Of course, we are very concerned about its cooling ability is excellent, and today we have to actually test.
Often concerned about the notebook channel friends know that we have a special "high-temperature environmental testing." And ordinary thermal testing are different, we will be completely sealed notebook into a constant temperature and humidity inside (commonly known as the oven), free to set the temperature inside the box, and then let the notebook in high-temperature environments running high-load period of time, thus simulating notebook hot in the summer operation of the region.
Normal environment, the standby state, the processor temperature is 48 , the graphics card temperature 45
High processor and graphics load cycle test software running on the left and gradually increase the temperature monitoring data
HP dv4-3011TX into the thermostat box, closed the door ready to heat. In order to simulate a real user of the game, we chose Furmark WinRAR software test software and graphics processor comes with the test procedure, the power management set to high performance mode, and external power (power line supporting cylindrical sponge exports will be exported to block).
Here we close the door, ready to start incubator heating mode. Test for one hour, the cabin temperature is 40 , enough to simulate the vast majority of our region's highest indoor temperature in summer.
We see that at this time dv4-3011TX processor temperature reached 91 , card temperature is 84 . And before we tested (including the unpublished article) compared to some models, this notebook's performance quite satisfactory, after all, at 40 environment, using this high-end notebook graphics cards, most of the core temperature will be 90 . In the actual game, we see that the processor and graphics card temperatures will be lower than this value, because the ambient temperature reached 40 the situation is not too much, and most of the game is also lower than the consumption of graphics cards the software Furmark
Next, we come up with dv4 from the thermostat box, and immediately back to its surface temperature of the eight locations were tested. We see that at 40 environment immediately after removal, in addition to the outlet from the right side of the keyboard closer to the higher temperature, the temperature of all other locations and the ambient temperature is almost the same. Of course, this will be a few seconds the body temperature down, but it also reflects from one side of the notebook's cooling capacity has reached an acceptable level.
Evaluation Summary:
And compared to previous test data, this notebook's internal temperature, although not particularly good, but did not affect the stable operation of the notebook, but mainly because it uses the graphics card than the previous test object higher standard, and have been tested more than 15.6-inch models. HP dv4 as a 14.1-inch high-performance graphics card models, such a performance it is difficult to have a.
In addition, its performance is quite good body surface temperature, internal heat is efficiently conducted to the air blowing out, there is no such board in touch with the user access to the site of frequent emergence of heat accumulation, and this point is worthy of recognition. On the whole, the HP notebook cooling capacity, and their products than in previous years have been significantly improved.
