How to know it's this
These are the symptoms that point at iMac fan + thermal repair. Match them against your iMac, then book a free diagnosis — we confirm the actual fault before quoting.
Fan running loud all the time
A failing fan bearing or dried thermal paste forcing the fan to overcompensate.
Hot to the touch at the top edge
Heat not being moved off the CPU/GPU — usually old thermal paste or dust-clogged heatsinks.
Shuts down or throttles under load
Thermal protection kicking in. Re-pasting and cleaning restores sustained performance.
Dust visible in the vents
Years of dust insulates the heatsink; a clean plus fresh paste drops temperatures sharply.
Why iTweak for iMac
Most repair shops won't touch an iMac. Apple's quote is usually a logic-board swap costing more than the iMac is worth.
iMac is an all-in-one — display, logic board, SSD, RAM, PSU, and chassis are bonded together in a way that intimidates most repair shops. Apple Authorised Service Providers will quote a full logic-board swap for any board-level issue (cost: ₹40,000+). iTweak does component-level work: replace the failed GPU chip (not the whole board), upgrade the SSD without breaking the display bond, replace the fan + thermal paste without damaging the 5K display ribbon. We've been doing iMacs since 2010. 1-year warranty on most repairs.
- Component-level board repair — not assembly swap
- Vintage iMac (2011–2014) GPU failure — our specialism
- 5K / 4.5K display work, bonded panels preserved
- 1-year warranty on most repairs
What iTweak fits — across every iMac repair
iMac repair is the clearest example of where independent specialists beat AASPs on price and engineering. The AASP quotes a "logic-board replacement" because Apple's parts catalogue lists the whole board; we do the actual repair.

How an iMac repair works at iTweak
iMac repairs are bench-only — they need proper display-separation tooling and ESD-protected work. Free FedEx pickup pan-India in iMac-grade packaging, or walk into our Marathahalli centre.
1Tell us the issue
Book online or call. Describe what's wrong (no display / GPU artifacts / SSD swap / slow / fan loud). Tell us the model — About This Mac → System Report → Model Identifier confirms it (e.g., 'iMac17,1').
2Free FedEx pickup or walk-in
Free insured pickup pan-India in iMac-grade packaging (custom-fit foam, ~30kg shipping weight). Or walk into Marathahalli (Bangalore). Typical round-trip: 6–8 working days from anywhere in India (iMacs are slower than smaller devices to ship).
3Diagnose and quote
Apple Diagnostics + bench-level testing (multimeter, microscope, thermal scan). We confirm the actual fault — GPU vs board vs SSD vs PSU — before quoting. Written quote, itemised, approve or decline.
4Component-level repair
Display panel safely separated using suction + heated mat (no heat gun). Component-level board work — chip replacement, capacitor reflow, BGA rework where needed. SSD swap where requested. Reassembled with Apple-spec adhesive.
5Test, calibrate, return
Apple Diagnostics post-repair, thermal calibration, display calibration. 1-year warranty paperwork. Return courier or walk-out.
If it’s not the battery, you don’t pay for the swap
Our 80-point Phonecheck diagnostic runs before any disassembly. If the issue turns out to be elsewhere — charging IC, board fault, software — we tell you, refund the booking, and quote the actual fix. No upsells.
- Pre-repair diagnostic on every booking
- Written quote before any work begins
- 100% refund if mis-diagnosed
- No part used without your sign-off

FAQ
Process, warranty, data, models — the imac fan & thermal repair questions our iMac techs hear.
In almost all cases, yes. Replacing a worn fan and re-pasting the CPU + GPU brings temperatures — and fan noise — back to normal. We test under load before returning it.
Every 4–6 years for a heavily-used iMac. If yours is older and has never been serviced, dried paste is a very common cause of noise and throttling.
Sustained overheating shortens the life of the GPU and board, so it's worth fixing early — especially on the vintage iMacs prone to GPU failure.
