I just replaced the stock Seagate 120 GB hard drive in my MacBook with a new 250 GB Toshiba HD. The new HD is quiet, but the fan is running about 70 percent of the time now--even when simply browsing a Web page. With the old HD, I would guess the fan ran 15 percent of the time. My system info shows that the drive heats up to about 99 degrees Fahrenheit. My question: is there any way to adjust the drive or fan so that the fan isn't running all the time? The fan is quite loud. Here are the drive specs: http://www.newegg.com/Product/Product.aspx?Item=N82E16822149070) Thanks!
