Technicians from our shop open and repair the MacBook. Nothing is outsourced.

Is your MacBook getting hot, with the fan loud and getting slower? Help Cell does preventive maintenance on your MacBook at Floripa Shopping, replacing the thermal paste with a technician from our shop. Looking for other repairs? Back to MacBook repair.
A MacBook thermal paste replacement is the maintenance where the old, dry paste between the processor and the cooling system is removed and replaced with new paste. It is for a MacBook that overheats, has a loud fan, slows down or shuts off from heat. At Help Cell the service is done at the workbench, in Floripa Shopping, by technicians with more than 10 years of experience, and you ask for the price on WhatsApp.
The thermal paste is a thin compound that fills the tiny gap between the chip that gets hot and the metal part that carries the heat away. Without it, there would be air in between, and air conducts heat very poorly. With the paste, the heat leaves the processor, reaches the heat sink, and then goes out of the notebook.
Over the years and many heat-and-cool cycles, this paste hardens, cracks and loses its ability to carry heat. The MacBook still turns on, but it starts to work hotter than it should.
The technician opens the MacBook, removes the old paste, cleans the surfaces and applies a new, thin layer. The goal is to recover the heat transfer the device had when it was new. It does not change any settings, does not erase files and does not touch macOS.
Overheating is when the MacBook spends too much time above a safe temperature. To protect itself, it slows down the processor, and that is when you feel the device is slow. Dry paste is one of the causes, but not the only one: dust, a faulty battery and programs stuck in the background also make the notebook hot.
In general, yes, but the cooling design varies. Some models have large fans and heat sinks, while others, like many MacBook Air models, work without a fan and rely more on the metal structure. That is why the exact model matters before any promise of result.
If you recognize one of these six signs, it is worth asking for a cooling check.
Four steps, from your first contact until the MacBook is back on your desk.
Tell us the MacBook model, how long it has been getting hot and what you do on it.
The technician checks whether the cause is the paste or another fault at the same time.
With the notebook open, the old paste is removed and the new one is applied.
We arrange the pick-up at the Floripa Shopping shop and explain what was done.
What you get in the price of the service and what is left out.
The price of the replacement depends on the model, how hard it is to open the notebook and what is inside it. That is why Help Cell does not publish a single price: send the model and the problem on WhatsApp and the answer comes with the price for your case.
| Factor | How it affects the price | Example |
|---|---|---|
| MacBook model | Each generation has its own way of opening and its own cooling system. | A MacBook Pro with a fan and an Air with no fan. |
| Condition of the inside of the device | Built-up dust and very hardened paste take more work. | A notebook used for many years and never opened. |
| Faults along with the heat | A swollen battery or a faulty fan need another part. | A MacBook hot because of the battery, not the paste. |
| Disassembly needed | Some models require removing more components to reach the chip. | A board held by more screws and connectors. |
| Doing it with another service | Using the opening for another repair can lower the total. | Thermal paste together with a battery replacement. |
Replacing the paste fixes a lot, but not everything. These are the points that cause the most frustration.
An old battery, dust in the fan and a program stuck using the processor can make a MacBook as hot as dry paste does. Before opening the notebook, it is worth finding out the real cause.
Fabric blocks the air vents and the notebook gets hotter, even with new paste. Always use a hard, flat surface.
Wrong screws, thin cables and glued parts are easy to damage. One small mistake can turn into a logic board repair much bigger than the maintenance.
Replacing the paste does not erase anything, but a backup protects you against any surprise. If you need help, Help Cell does data backup.
Write down whether it gets hot when you open a program, while charging or after hours of use. This helps the technician find the cause faster.
The shop may need to turn on the MacBook to test it. Check with Help Cell what it needs before you leave the device.
An overview to help you understand your situation. Which path is right for your MacBook, the technician tells you after the check.
| Criteria | Preventive thermal paste | Overheating from another fault |
|---|---|---|
| How it starts | Heat rises slowly, over months | Appears suddenly, after a drop or liquid |
| Main symptom | Loud fan and slowness under load | Shuts off, restarts or does not charge at all |
| Where the cause is | Heat transfer from the chip to the heat sink | Battery, logic board or electrical part |
| Recommended service | Thermal paste replacement | Battery replacement or logic board repair |
| When to act | As soon as you notice heat above normal | Right away: stop using it and bring the device in |

Mykael looked after me really well, proactive and attentive. He installed my camera protector and helped me choose a case with care. It was an iPhone 17 Pro Max. Congratulations to the store!
Celio De Melo MatosGoogle review, Feb 2026They replaced my phone battery the same day even though it was an older model, and they also worked hard to find and apply a screen protector. Everything came out right, they do a great job with good service from the whole team.
Cristina RubyGoogle review, Jun 2026I love this store, and Matheus's service definitely makes all the difference. He deserves the best rating possible! I recommend the store with my eyes closed and I will happily buy here again. Score: 10000.
The price depends on the model, the internal condition of the device and whether there is another fault along with it. Send the model and the problem on WhatsApp +55 48 99110-7381 and Help Cell will reply with the price.
The time depends on the model and on what the technician finds inside the device. Help Cell tells you the time for your MacBook when it sends the price, before you leave the notebook with us.
No. Replacing the thermal paste does not touch the disk or the system, so photos, documents and programs stay as they are. Even so, make a backup first, just to be safe.
Heat that grew little by little, a fan that is always loud and slowness under load point to dried-out paste. Only the check confirms it, because the battery, dust and a logic board fault cause similar symptoms.
There is no single schedule: it depends on the model, the climate and how you use the notebook. The best guide is the symptom. If the MacBook has started to get hotter than before, it is worth a check.
Yes. The 90-day warranty covers the service against defects. It does not cover drops, liquid or misuse after the maintenance.
Probably not. After liquid, the heat usually comes from corrosion on the logic board. Turn off the notebook, do not charge it and read MacBook with liquid on the keyboard: steps and chemical cleaning.
Yes. The pick-up and delivery service covers Greater Florianópolis, for any service, with a fee.
