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