Thermal paste
Commonly fills microscopic gaps between a CPU or GPU and its heatsink. It is usually the lower-risk choice, but a repaste only helps when the interface is part of the problem.
Cleaning, fans & thermal service · Sydney
Computer cleaning & cooling service
Laptop running hot, fans constantly loud, or gaming performance dropping after a few minutes? We inspect the cooling system, clear the internal airflow path and recommend paste, fan, air-cooler or liquid-cooler work only when the device and evidence justify it.

Cooling symptoms
Signs the computer needs a cooling check
These symptoms can come from dust or an ageing thermal interface, but a fan, software load or hardware fault may be the real cause. We separate those causes before recommending work.
Hot laptop or keyboard
The base, palm rest or exhaust becomes unusually hot during ordinary work.
Fan always loud
The fan races at idle, rattles, pulses repeatedly or no longer moves enough air.
FPS drops and stuttering
Games start normally, then slow after heat builds and the CPU or GPU throttles.
Heat-related shutdowns
The computer freezes, restarts or powers off under gaming, rendering or heavy work.
Dust visible at vents
Lint, pet hair or compacted dust is blocking intake and exhaust openings.
High temperatures under load
Monitoring shows sustained heat or thermal throttling, not just a brief temperature spike.
What the service includes
A real internal clean, not air sprayed through the vents
The exact work depends on the model and cooling design. We confirm scope and price before opening the device.
Standard cooling service
- Initial symptom, fan and temperature check
- Careful access to the internal cooling path
- Dust removal from fans, vents and heatsink fins
- Fan condition and cable inspection
- Thermal paste replacement where suitable
- Reassembly and post-service temperature/load check
Checked and quoted separately
- Damaged or noisy fans: replacement part and labour
- Thermal pads or putty: correct thickness/material must be confirmed
- Liquid-metal systems: model-specific risk assessment
- Ultrathin or adhesive-sealed devices: extra disassembly time
- Liquid-cooling faults: pump, radiator or coolant work
- Board-level damage: separate repair assessment
Devices & cooling work
From everyday laptops to high-end gaming PCs
The service can cover internal and external cleaning, vents and ports, fan and heatsink cleaning, cable and airflow review, and model-appropriate cooling parts.
Laptops & gaming laptops
Fan and heatsink cleaning, thermal repaste where appropriate, and checks for throttling, noisy fans and blocked exhausts.
Desktop, gaming & all-in-one PCs
Internal and external dust removal, port cleaning, cable management, case-airflow review and load testing.
Workstations & office computers
Preventative cleaning for workstations and office fleets affected by dust, sustained load or fan noise.
Fan replacement & airflow upgrades
Replace failed CPU, GPU, laptop or case fans where parts are available; review fan direction, curves and case airflow.
Air-cooler installation
Fit or replace compatible CPU coolers, check socket hardware, mounting pressure, clearance and thermal contact.
AIO liquid-cooler installation
Install or replace compatible sealed AIO coolers, position the radiator correctly, connect the pump and fans, then test operation.
Services from $100
Final pricing depends on the exact model, accessibility, contamination level and whether paste, pads, a fan, cooler or another part is required. Liquid-metal work and complex laptops usually need more disassembly and testing time, so we quote them after reviewing the model.
Cooling materials explained
Paste, pads, liquid metal and cooling hardware are not interchangeable
Using the wrong material—or the wrong thickness—can worsen contact or damage components. We identify the original design before changing anything.
Thermal pads & putty
Often used on VRAM and power components. Thickness and compressibility matter: a mismatched pad can lift the heatsink away from another chip.
Liquid metal
Offers high thermal conductivity, but it is electrically conductive and must not contact aluminium. Removal, masking, inspection and controlled reapplication take longer; contamination can damage a board. We assess the model and existing condition before accepting the job.
Heat pipes & vapour chambers
These are sealed parts that spread heat across the cooling assembly—not consumable paste. If a pipe, chamber or contact plate is damaged, the correct remedy may be replacing the heatsink module.
Fans & air coolers
A failed fan, poor mounting or restricted case airflow will not be fixed by paste alone. We can replace compatible fans or CPU air coolers and verify direction, clearance and speed control.
Sealed AIO liquid coolers
An AIO combines a cold plate, pump, tubes, radiator and fans. Most are factory-sealed: routine work means cleaning the radiator, testing the pump or replacing/installing the unit—not opening or refilling it.

How it works
Inspect, clean, service and test
Send the model
Tell us the exact laptop or PC model, symptoms and whether it has been opened before.
Prepare the on-site visit
We confirm the exact model, symptoms, previous work and access requirements in advance, then bring suitable cleaning tools and likely thermal materials to the visit. If a small number of specialist systems need extra operating conditions or extended testing, we explain the arrangement before booking.
Clean and service
We document what is found, clean the cooling path and replace thermal materials only as agreed.
Verify the result
We check fan operation, temperatures and stability rather than assuming a clean automatically fixed the fault.
Cleaning or repair?
Book the service that matches the symptom
| What you notice | Best starting point | Why |
|---|---|---|
| Dust, loud fans, heat or throttling | This cleaning & thermal service | Targets airflow and the cooling interface, then verifies temperatures. |
| Blue screen, boot failure or random crashes | Computer repair & diagnosis | The cause may be memory, storage, drivers, power or hardware rather than heat. |
| Slow at all times but not hot | Performance diagnosis | Startup load, a failing drive or insufficient RAM is more likely than dust. |
| Files missing or drive failing | Data recovery | Protect the data before cleaning, reinstalling or stress testing. |
Before you book
What to know before cooling-system work
Will new thermal paste definitely make my laptop cooler?
No. It can help when the old compound has degraded or the heatsink has been removed, but dust, a failing fan, poor mounting pressure, software load, damaged heat pipes or the device’s original cooling design can be the real limit. We diagnose before promising a repaste.
Can you clean a gaming laptop or replace GPU thermal paste?
Often, yes, but the model matters. Gaming laptops may use several paste, pad or putty types and some use liquid metal. Send the exact model number first so we can confirm the safe scope and service method.
Do I need to back up my files?
Cooling work normally does not require opening your files, but any hardware service carries some risk. Important data should always be backed up before disassembly or load testing. If the drive already shows warning signs, data protection comes first.
Can the work be done on-site?
Yes. On-site service is the main way we deliver this work. Before the appointment, we ask about the exact model, cooling symptoms, previous repairs and site conditions, then bring the appropriate cleaning tools, thermal paste and likely materials. For the small number of systems involving liquid metal, severe contamination or unusually complex disassembly, we explain any additional operating or testing requirements after reviewing the model—not after arriving.
How long does liquid-metal or complex cooling work take?
It usually takes longer than a standard clean because the technician must protect surrounding components, remove residue carefully, inspect the contact surfaces and test the system after reassembly. Timing and cost depend on the model, previous work and contamination; we quote after assessment rather than promise a universal turnaround.

These reviews describe laptop cleaning, thermal work and high-end CPU/GPU cooling jobs completed for Sydney customers.
“The computer was cleaned and the thermal paste replaced. The shop owner sent someone to my home to do it; they were very meticulous, and the computer booted up successfully. I even got a discount because I’m a student at Xin Nan University. Highly recommended.”
“He gave my computer a thorough cleaning and also successfully diagnosed and fixed a hardware malfunction. The results were immediate; my computer’s temperature dropped significantly, and gaming was smoother and less choppy.”
“excellent service from technician absolutely amazing fixing my cpu and gpu cooling system on such a high tier computer. Legend, fast and straight forward”
