Is your laptop extremely slow, programs opening at a snail's pace, and the fan glowing as if the device is about to take off? Especially in 1100 Favoriten, this often happens precisely when you urgently need your laptop for work, school, university, or private appointments. Often, there's more to it than just "too many open tabs": dust in the cooling system, old thermal paste, software problems, a failing hard drive, or even an incipient hardware defect can be the cause. At ClickInternet, we professionally and quickly check your laptop without an appointment, so you can get back to work relaxed.
What to do when your laptop is extremely slow & the fan glows? Immediate measures
- Don't immediately restart the laptop repeatedly if it's already very hot. Let it cool down first so that the processor, graphics unit, and battery are not put under additional strain.
- Place the device on a hard, flat surface. On a bed, sofa, or blanket, ventilation slots are often blocked, causing the temperature to rise even faster.
- Close unnecessary programs and browser tabs. If the RAM is full or the CPU is constantly running at 100 percent, the laptop will slow down and the fan will constantly spin up.
- Avoid your own cleaning attempts with a vacuum cleaner, compressed air from a short distance, or sharp objects. This can damage fan blades, ports, or sensitive components.
- Bring the laptop to ClickInternet for a free diagnosis. We check temperature values, fan, SSD or hard drive, operating system, autostart, suspicion of malware, and the general hardware condition.
Why an extremely slow laptop & glowing fan needs professional help
When a laptop becomes extremely slow and also runs very hot, hardware and software often no longer work together cleanly. Clogged heatsinks, dried-out thermal paste, defective fan bearings, an aging HDD, faulty drivers, or an overloaded operating system can lead to thermal throttling – where the processor automatically reduces its performance to prevent damage. Self-repair is risky because the motherboard, heat pipe, battery, display cable, and sensitive connectors can be easily damaged when opening the device.
- The fan runs loudly continuously, even though only a few programs are open.
- The laptop becomes very hot on the underside, keyboard, or near the display.
- Windows or macOS starts slowly, freezes, or responds with significant delay.
- Programs crash, updates get stuck, or the laptop suddenly shuts down.

ClickInternet is an A1 Partner, providing you with reliable service, experience, and clear processes. Diagnosis is free with us: We first check why your laptop is overheating, why the fan is working so hard, and why the system has slowed down. Only then do we explain in an understandable way which solution makes sense – for example, internal cleaning, fan service, replacing a slow hard drive with an SSD, software cleanup, data recovery, or a check of the battery and motherboard.

At ClickInternet, you get fair prices and full transparency. We don't just start with a repair; we first perform a free on-site diagnosis. Then, we give you the exact price before we start – no hidden costs and no unpleasant surprises. Depending on the cause, the solution can be very different: sometimes a thorough cleaning of the cooling system is enough, sometimes software service is necessary, in other cases an SSD upgrade or the replacement of a defective fan is worthwhile.
