Laptop Dust Cleaning — Belgrade

Laptop cleaning — the cheapest way to get your speed back

A laptop that hasn’t been cleaned in 2–3 years starts acting up for no obvious reason. Sluggish performance, a fan that’s always blowing, the occasional shutdown under load. Most of that is fixed in an hour — a full dust cleaning plus fresh thermal paste.

How to tell your laptop needs cleaning

  • The fan blows hard even during light tasks (reading a website, Word)
  • The underside gets so hot you can’t keep it on your lap
  • It shuts itself off after 10–15 minutes of gaming or video editing
  • The battery report (powercfg) shows “Throttled CPU” more often than before
  • You opened the bottom cover once and saw black “carpets” of dust around the fan

Exactly what we do

  1. We open the bottom cover (every model is different — we know the sequence for most)
  2. We take out the fan and heatsink — that’s where dust builds up the most
  3. We clean the fan by hand (compressed air in an enclosed space usually doesn’t help — it just pushes dust into deeper areas)
  4. We remove the old thermal paste from the CPU/GPU — it has dried out and lost its function
  5. We apply fresh premium paste (Arctic MX-6 or MX-7, Thermal Grizzly) — we use it on every device, at no extra charge
  6. We replace the thermal pads if they’ve hardened (under the GPU, RAM, or VRM modules)
  7. We reassemble and test temperatures before and after with HWMonitor

Typical difference: a laptop that used to hit 92°C under load runs below 70°C after cleaning. That’s the difference between “the system keeps shutting down” and “the system runs calmly.”

Service prices — in the official price list

All our service prices (diagnostics, repairs, cleaning, reinstallation…) are on our price list page and are always up to date. We confirm the final price after a free diagnostic, before any repair. A courier picks up and returns your device, or you can bring it to one of our shops.

How often is it worth doing?

Personal advice: every 18–24 months for people who keep their laptop at home. More often — once a year — if you have pets (hair gets into the fan) or if you use the laptop outdoors (parks, cafés). Cleaning is the least time-consuming intervention that restores performance.

Questions

Can I clean it myself? What are the risks?

You can, but there are risks. The most common mistake: reaching for compressed air without dismantling the fan — the dust just moves into deeper areas. The second: losing screws that are of different lengths, which damages the threaded hole. The third: applying too much thermal paste so it oozes off the CPU onto neighboring components. If you’re not comfortable with electronics, bring it to us.

Does cleaning void the manufacturer’s warranty?

Most modern laptops have “Warranty Void If Removed” stickers that tear when you open the case. In Srbija this rarely matters in practice, since manufacturer service centers aren’t very numerous here anyway. But if your laptop is new and under warranty, check with the manufacturer before cleaning — some perform maintenance for free while it’s covered.

How often should thermal paste be replaced?

Thermal paste dries out in 2–4 years. If your laptop is 3+ years old and you’ve never replaced it, it’s time. After the first change, the next one isn’t due for another 3–5 years (higher-quality paste lasts longer).

Can I send the laptop by courier, or do I need to bring it in person?

Whichever suits you — by courier or in person. We do cleaning exclusively at the shop, never on-site: it requires dismantling parts and a dry, clean space with an ESD mat and compressed air in a controlled environment. The courier picks up the device, we clean it, and send it back.

Frequently asked questions

How long does laptop dust cleaning take?
In most cases the same day or the next one. Opening the machine, clearing the dust out of the heatsink and fan, replacing the thermal paste and putting everything back together usually fits into one working day. If it's a laptop that is hard to take apart (glued-together chassis, a thin ultrabook), we let you know up front if it needs a bit longer.
How much does laptop cleaning and thermal paste replacement cost?
Diagnostics are free, and we give you the exact price after we've looked at the machine, because it depends on the model and on how hard the laptop is to take apart. Ballpark prices are in our price list. If the job also calls for a better paste or thermal pads, we tell you before we start — nothing gets added to the bill afterwards.
How do I know my laptop needs cleaning?
The usual signs are a fan that runs flat out all the time and is loud, an underside that gets hot, and a laptop that slows down or shuts itself off under load (games, video editing). Those are the classic symptoms of overheating caused by a clogged heatsink and dried-out thermal paste. We measure the temperatures before and after so you can see the difference.
Will I lose data when the laptop goes in for cleaning?
No. Dust cleaning and a paste change are mechanical work — we don't touch the drive or your data. Everything stays exactly as it is. If for some reason we have to disconnect the drive, we put it back exactly the way it was.
How do I get my laptop to you for cleaning?
For private customers, a courier can pick the laptop up at your address and bring it back once it's done, or you can drop it off yourself at one of our three shops in Belgrade (Arena, Piramida, Centar). We give a warranty on the work, so if something connected to the same job shows up afterwards, we sort it out at no extra charge.
