![]() ![]() I don't know why the gpu temperature isn't showing though, sorry. this fan problem didn't exist when the psu was in the low 40s on another imac that had the t7550, hence my speculation My theory why the fans act this way is: psu is cooled by cpu fan > psu is constantly high temperature > cpu forced to go hard > psu still hot > ODD fan goes hard as a failsafe to increase airflow into the chassis. got a question myself about it and searching through ifixit for any hiding solutions. Hey someone, did you get it fixed? having a similar issue with the fans and i believe it's to do with the PSU temp being in the high 60's. Here’s the needed kit to do this job Arctic Silver Thermal Paste Keep in mind it doesn’t take much for the task! I often got systems in after people tried, they would empty every last bit of what they bought coating everything! So wrong! To help you see how much you really need take a single layer of face tissue cut it down to the size of the chips heat spreader now using some water wet it and roll it into a tight ball thats how big the amount you want of TIM for that chip. Given the age of the system I would also recommend cleaning off the old thermal paste (TIM) and apply a fresh coat. Then using a can of can’ed air with short blasts blow away the junk. So the ODD fan gave up and now needs to be replaced! Here’s the guide to get to it iMac Intel 20" EMC 2266 Optical Drive Fan Replacement Here’s one source for the fan 20” iMac Optical Drive Fan, Apple P/N 922-8841īut you really need to pull the logic board so you can get to the head sinks to clean them as well as the other fans iMac Intel 20" EMC 2266 Logic Board Replacement To do it properly you’ll need a small soft paint brush that you can use to scrub the fan blades and cowlings and the head sink fins as well as the rest of the system. Your real issue is likely a simple dust buildup! Over time the fan blades and the heat sink fins get clogged up with dust and other debris making it harder to shed the CPU & GPU’s heat and your reaction is pump up the fans RPM’s which then wears the fans out and at some point one or more fans fail as they where pushed too hard with all of the junk loaded on them! I prefer this app TG Pro.īut your issue is not the CPU Diode that’s just merely the sensor within the CPU chip frame and not the GPU at all. As these systems can be a bit tricky.įirst MacsFanControl is not very good as it doesn’t get you enough useful information or offer the better way to manage your systems fan’s if you need to. You can artificially increase the fan speed to further reduce the CPU's heat, but this will also increase fan noise.You’ll need to find someone with Mac repair skills to fix your system. Your Mac might run slower, but there's nothing to worry about. When your Mac gets hot, it starts throttling your CPU until the temperature gets under control. Some Caveats Before You Start Controlling Fans In case there's a problem in the hardware, the data from your fan can help build a case for an AppleCare repair.You can monitor the fan speed to see if your Mac maintains a normal operating temperature of 10-35 degrees Celsius.While there's no ideal speed range of the fan in any Mac model, seeing consistent readings during normal system usage can be assuring.If you use your Mac in a noise-sensitive environment, controlling the fan speed can reduce the noise for a brief period.When you replace a component, the log data of fan speed can help you check the integrity of low-level components and temperature sensors.It enables you to see what different sensors are showing, analyze temperature patterns, and review your fan's speed.A third-party utility for this purpose can be useful in many situations: Like most computer manufacturers, Apple does not let you directly control the fan's workings. ![]() Why Use an App to Monitor and Control Fan Speed? ![]()
