HD Fan speed.
I have an iMac 21.5 3.06 GHZ Intel Core i3. Orig HD 500 GB HD packed up so I took the opportunity to replace it with 1T Seagate. Now HD fan starts slowly ~ 1,000 rpm, but after half an hour or so is doing 5400 rpm. Stays there. Temp all the time is cool at 41°C. (smcFanControl says temp 0°C, 5400 rpm) Service said HD Fan overspeed is because 1T seagate is not an Apple HD I have to live with it. Bit of a tall one if you ask me. I have tried FanControl and smcFanControl to no avail. Would anyone have any solutions? It was really great - before. ;-( -- You received this message because you are a member of the iMac Group, a group for those using Apple iMacs and eMacs.

It's quite likely that your new hard drive runs hotter, particularly if you've installed one with a faster RPM. I've seen this on several machines that I've upgraded. -- You received this message because you are a member of the iMac Group, a group for those using Apple iMacs and eMacs.

Re: HD Fan speed.
As 0 degrees Centigrade is freezing point - what exactly is smcFanControl measuring here? Is HD drive temp measured by an external probe or is it an onboard function - I use iStat menus, and hard drive temp measurement seems to be a function of SMART monitoring, but in my G4 iMac it just shows one measurement of 41 deg C, which I presume is CPU temp. Is an NVRAM reset perhaps the solution here? Just a thought - but I'm waiting for Bruce or Dan, who usually seem to have the answer on this sort of problem. Dan (the other one!)

So i would like to test my machine. -- You received this message because you are a member of the iMac Group, a group for those using Apple iMacs and eMacs.

Re: HD Fan speed.
Have you installed or are you aware that Apple have temperature sensors plugged into their hdd's? It is much like a jumper and if you have missed it, this will account for why the fans are spinning full wack.

Re: HD Fan speed.
Now I read somewhere and as best as i can remember, a chap swapped out the apple hard drive for a new one in his iMac and the fan simply went full belt constantly. He claimed that he discovered that apple place a jumper on their hdd's to control the fans. He took out the new, replicated the jumper position on the original hdd and it worked.
