Hello fellas, first time post here and a noob question. I've had my MBP 2.4 i5 since early June and I noted a noticeable vibration. I'm not quite sure if it's the fan working or the HDD spinning. istat shows my fan running at 2000 on average both left and right, GPU and CPU temp around 38 on normal operation such as browsing on safari. The reason I asked is because my older MBP 2.16 C2D (3 years old) seem to not have this issue or characteristic. I would even notice the vibration with my hand resting on the desk the new MBP sits in. This happens even with waking-up the MBP from cold sleep. As stated, no intense app or tasks are involved, just plain browsing thru safari. Thanks in advance for your opinions on what this may be related to or any advice you all might have for me.
