Is it possible to troubleshoot cooling fans

Is there a way to troubleshoot the cooling fans ?

It seems like my iMac has been getting hotter than it used to.

The upper half of the back side of the machine is getting so hot it's almost untouchable. Also the screen seems like it's giving off more heat than it used to.

What's the best way to troubleshoot this issue, aside from just replacing all the fans.

Thanks in advance for any help anybody can give.

I would start with a temp & fan monitoring app like Temperature Gauge Pro. There are others out there I just find this one to be very reliable.

Given the age of your system I'm sure it has a bit of dust buildup internally. The dust acts like a blanket preventing the system from properly cooling. A can of can'ed air and a soft brush is what I would use to clean out the dust. I would also make sure to follow proper ESD precautions as the winter months tend to be more statically which can damage your system.

Use the blue squire ribbon icon in the answer field to paste a screen shot of what Temperature Gauge shows you.

Dan, quick question...since I haven't opened an iMac, if I use my anti static wristband attached to the iMac's support stand/arm/base will that be ok...does that base have good enough properties to clip to...just wanna make sure, since u seem pretty knowledgeable...thanks


Yes, a wrist strap connected to the case (after you pull the display) it the better placement. You'll still want a connection to a good grounded outlet ground point from your system The other issue is your work surface I would get an anti-static mat if you plan on taking the logic board out. Then I would have the strap connected to the mat. And again connect it to the ground point of the outlet.

Dan, thanks so much for the reply, I will try what you suggested this weekend and post my findings...I agree with the dust theory, as I live in the Miami, FL area, dust is a constant here as it's such a congested, heavily populated area there's all kinds of dust & other crap flyin around in the air all the gets to be a challenge keeping things clean, even inside the house...

Thanks again...
