Just a minute ago my iMac's fan stopped spinning (sound like it broke). I heared no noise coming out of it anymore and I quickly checked iStat which reported a fan rotation speed of 0 rpm (usually 1500 rpm). I turned my Mac off immediately.What should I do?
Why is the fan so loud? The fan on my iMac Intel 27' is so loud and I wonder how to fix it. Clean away the dust and debris then add about 2 drops of 3 and one oil down in the center where it gets inside of the fan housing. If it still makes noise, you probably have a bearing going out - these fans spin hundreds of revolutions per.
I am in the Netherlands so there are no Apple Stores here.I also don't want to turn it on again because that could result in a CPU meltdown (usual CPU temperature was 42°C). Very little chance the fan turned off because the CPU was cool at that moment, since I was playing Minecraft, converting four videos and playing one at the same time.My iMac is a model from 2010, 21 inch. What can I do? You should certainly request help or through the phone - (31) 0900 7777 703 - in either Netherlands or the country where your mac was originally sold. Fans are pretty easy to diagnose remotely since it's almost always the fan unit failing (or when it's not that, the next most likely cause is simply reconnecting the fan cable) so you can often ask for a parts and labor quote to help you decide what to do.You seem to indicate it's the CPU fan.
It and the hard drive fan are very hard to replace as you have to disconnect and remove the LCD panel, the logic board and many of the other parts. The optical fan is more amenable to a DIY repair. All the connectors are very delicate and if you break them, the cost to repair can be pretty large. (Think $800 to $1100 for a whole logic board). Has good take apart manuals and once you have a quote or two from authorized service providers, you might decide to get inside to reconnect the cables and at least look around.My advice is don't do anything yourself until you're sure Apple won't cover it by calling them first to get a quote.
The has great links for getting service worldwide - since it's quite long I'll pull the links here for quick reference:.Lastly, don't be afraid to run it for short time and low CPU use to get more information and be sure which fan went out. The CPU will reduce clock rate when it gets warm, then it will go to sleep for 30 seconds if that doesn't keep it cool, next the OS will shut down (all of the above events get logged at default settings except maybe the clock rate). The CPU will also shut everything off abruptly if all of the above fail. Don't run for weeks or hit the CPU with 100% tasks and expect it to last for years with the CPU fan off, but other things will have to fail for it to be a melt / fire hazard issue.
I also wouldn't run it needlessly and risk MLB failure needlessly. That's a bummer.
Which fan is it? Anyone could take your serial number into an Apple Retail store and ask the genius bar for a parts and labor / non binding estimate for the repair. Then you could check in the Netherlands for alternate computer repair services armed with the part number. Apple often is the best bet as they work on the most macs, but surely some shops there are capable of getting in the iMac. It's way harder than almost any PC repair so the corner upgrade shop might be your last choice, but you're not out of options. I'd guess the US cost would be $50 to $120 for fan+labor.–May 5 '11 at 23:45.
Swapping the HDD for another HDD or SSD should not cause the condition you mention. That condition is a function of the Mac's diagnostic system and can be controlled via the Mac's diagnostics programs (older models actually had a diagnostic disk you booted separately to manage this).In your case, this should not be an issue. Swap to your heart's content.hello COLGeek.sorry, i have mistaken the model and it turns out to be a mid 2010 27inch model (A1312/EMC2390). Will i still have the problem of the fan reaching high rpms if i switch out the HDD?And also if i were to install an ssd, is there a bracket to buy or just double sided sticky tape the ssd to the back of the imac?Thanks!
