Imac fan goes into hyper-speed after hard drive replacement.
If you’ve upgraded your iMac’s hard drive lately, or replaced it when it went bad, I bet you were surprised to find that after the install, the fan went into hyper-speed and never, ever stopped again. Wheee. That happened recently to client’s computer. Their hard drive went bad, and we had to replace it. After the repair all seemed good, but then a few days later the client called. and said the fan was too loud. I dropped by the client’s business, and not only was the fan really loud, it spun at full speed every single moment, as if it were micmicking a the blades of helicopter about to take off. I couldn’t figure out why until I researched it in depth on the internet.
Turns out there is either firmware in all Apple-configured hard drives or a heat sensor cord attached to one and if you replace it with an ordinary drive, the fan will go hyper. iMacs before model 11,3 come with a heat sensor cord and when you replace your hard drive, you need to buy and install a heat sensor cord specific to the type of the new hard drive. The cord goes from the hard drive to the motherboard. It will regulate the fan. Yet with the 11,3 and newer models, Apple stopped using the cords. Oh no. I thought I would have to tell the client, their fan would never, ever stop again. It had gone manic and too loud forever.
I found out that there is an answer, however. You can get software that will regulate the fan for you. It is called SMC Fan Control. You can download it here from Cnet’s Download.com.
So tomorrow I’m remoting into my client’s computer and installing it and getting that fan under contol.

In December, Apple announced that Mac users should install anti-virus protection, but since then, they’ve withdrawn the story. However, it makes sense, as more people buy Macs, the more virus creators will create malware for Apples. So if you own an Apple computer, a little precaution is advised. Here is a link to avast! for Macs. No harm in installing it. Just to be safer.

Finally a Mac anti-spyware. Macscan. I know many Mac users think you don’t need anti-virus or anti-spyware, but it really isn’t wise to go without. There is malware out there designed for Apple machines. Click here to check Macscan out. I am going to test it on my Mac too.
Here is an article about fraudulent anti-spyware program called MacSweeper.
And as more and more people switch to Macs, the more spyware and viruses there will be. Mac users have a right to be smug about having a safer OS, but even one spyware or virus unchecked can wreck havoc on a computer. It never hurts to play it safe.
I haven’t found what I’m looking for yet: a free anti-spyware for Mac computers. (Yes, it’s true I’m afraid, I use both PC and Mac, for awhile I even dabbled in Linux. I know for those of you in the die-hard polarized-camps of Apple versus PC it’s hard to believe, but, in fact I’m so bi-OS sometimes I forget what kind of computer I’m working on. It’s a tool, not a religion.) And unlike some Mac users, I do believe running in virus software on my ibook. There are malware authors out there in cyber-space who specialize in Apple viruses and spyware, fewer in number, perhaps, than the PC bad guys, but still enough to put our computers at risk. Prevention is so less messy and so much preferable than cleanup. I use Virex from days when Apple included it in their Mac services. When Apple stopped sending updates, I found a site where I can download them for free. However, I can’t seem to find a free anti-spyware for Macs. If any of you readers know of one, please let me know.
