 About the Product:

 This set consists of three genuine Apple fan modules used in the internal cooling system of the iMac A1224 model. They help cool the internal components of the device, preserving both performance and hardware lifespan.

 Set Contents and Functions:
 1. Delta BFB0712HHD – 620-4322
 This fan is responsible for cooling the graphics card (GPU). If your iMac is running at high temperatures or there's excessive fan noise coming from the graphics card area, this fan may be faulty. If the fan isn't spinning, makes a grinding noise, or is running at a low speed, it may need replacing.
 2. Delta BFB0612HB – 620-4324
 This fan provides general air circulation around the motherboard and processor. Dust accumulation or bearing wear due to prolonged use can reduce its performance. Overheating or fans consistently spinning at high speeds may indicate a problem with this fan.
 3. Sunon B1208PTV1-A – 620-4323
 It is responsible for cooling the hard disk drive (HDD) and optical drive. If there is excessive overheating or fan noise in the storage area, this module should be checked.

 You can perform a detailed analysis by using the Mac Fan Control application to monitor fan speeds and temperature readings.

 Common Problems:

 A constant loud fan noise from your iMac, one fan not spinning at all, or clicking noises due to friction are all signs of a fan malfunction. Damaged fan bearings, dust accumulation, or liquid contact can all cause these problems.
