iMac overheating
Loud fans, warm casing and CPU throttling on an older iMac is almost always one thing - Dubai dust packed into the cooling fins behind the logic board. We open, deep-clean, replace thermal paste and pads, and your iMac runs quiet again.
Mohammed, iMac thermal restoration

Quick answer
Dubai's combination of fine dust and 12 months of air-conditioning is brutal on iMac cooling. A 2017 or 2019 iMac that's been sitting on a desk for five years almost always has a thick mat of dust across the heatsink fins behind the display - exactly where the fan is trying to push air through. The result: the fan spins flat-out, the casing gets hot to touch and the CPU throttles down to half its rated speed.
The fix isn't expensive but it does require display removal, which is the same delicate process we do for SSD upgrades. Once open, we vacuum the dust, replace the dried-out thermal paste between CPU/GPU and heatsink, swap any compressed thermal pads, and inspect the fan bearing. The iMac comes back quiet, cool and running at full speed - usually 20-30% faster in benchmarks because throttling is gone.
Confirm thermal cause
We run intelTM (or powermetrics on M-series) to confirm CPU/GPU temps under load and prove throttling is happening.
Display removal
Same careful adhesive cutting as our SSD upgrade - display lifts off without cracking.
Vacuum + brush clean
Heatsink fins, fan blades and intake/exhaust paths cleaned of dust. Compressed air alone doesn't do it on a Dubai-aged iMac - needs proper brush work.
Thermal paste + pads
Old paste removed with isopropyl, fresh Arctic MX-6 or Honeywell PTM7950 applied. Thermal pads replaced where compressed.
Reseal and verify
Display refit with fresh adhesive, cure overnight, then a 30-minute load test to confirm temps are 15-25°C lower than before.
