关于T61的主机运转音量与X61相比,兹附上原厂数据如下:
ThinkPad T61:
Acoustic noise level: Category 3D (office environment)
‧ Low cooling fan speed:
– Sound power level: 3.7 bels (idling), 4.0 bels (HDD seeking)
– Sound pressure level at the operator position: 31 dB (idling), 34 dB (HDD seeking)
‧ Middle cooling fan speed:
– Sound power level: 3.9 bels (idling), 4.0 bels (HDD seeking)
– Sound pressure level at the operator position: 33 dB (idling), 34 dB (HDD seeking)
‧ High cooling fan speed:
– Sound power level: 4.0 bels (idling), 4.1 bels (HDD seeking)
– Sound pressure level at the operator position: 36 dB (idling), 37 dB (HDD seeking)
ThinkPad X61:
Acoustic noise level: Category 3D (office environment)
‧ Sound power level:
– 3.4 bels (idling)
– 4.4 bels (operating)
‧ Sound pressure level at the operator position: 41 dB (HDD seeking)
当X61全速运转时(例如执行3D测试程序),站长个人觉得风扇声会比T61大声一些。至于原因为何,站长个人推测是因为T61/R61-Series采用的风扇转速较低(配合猫头鹰翼设计),且主机底部采用「通风断热」进气结构。但上述设计的前提是主机须保留足够的空间与厚度才能有效发挥作用。反观X61-Series主机设计考虑点为轻薄化,大型散热风扇与垫高底部的进气孔不适合用在B5-Size机型内。除非将来采用超低电压板CPU,朝「无风扇」发展,但届时效能与主机噪音之间的平衡点又会是使用者难以取舍的难题了吧。 |
