PC overheating repair West Bromwich is one of the most common jobs on our bench, and it is nearly always fixable. Is your PC running slowly, shutting down without warning, or getting too hot to touch? Overheating is one of the most common — and most damaging — PC problems, because sustained high temperatures degrade your CPU, GPU and storage over time. Mojoo Limited diagnoses and fixes overheating and performance issues for desktop PCs and laptops across the West Midlands from our West Bromwich workshop.
Signs You Need PC Overheating Repair West Bromwich
The most obvious signs are unexpected shutdowns or restarts during heavy tasks, a fan that runs at full speed constantly, a chassis that is very hot to the touch around the vents, and performance that drops suddenly mid-task (thermal throttling). You may also see blue screens (BSOD) with temperature-related stop codes such as THERMAL_SHUTDOWN or WHEA_UNCORRECTABLE_ERROR. Any of these symptoms is worth a PC overheating repair West Bromwich check before the hardware is damaged.
What causes a PC to overheat?
Dried-out or missing thermal paste
Thermal paste between the CPU (and GPU) and its heatsink dries out and cracks over time — typically after three to five years. When it fails, heat transfer drops dramatically and temperatures spike. Replacing thermal paste is one of the most cost-effective repairs we do and often brings CPU temperatures down by 20–30°C immediately.
Clogged or failed fans and heatsinks
Dust accumulates inside cases and clogs heatsink fins, reducing airflow to almost nothing. Fan bearings also wear out and slow down or fail entirely. We disassemble the cooling system, blow out dust with compressed air, clean heatsink fins, and replace any fans that are no longer spinning at the correct speed. Dust removal is included in every PC overheating repair West Bromwich we carry out.
Poor case airflow
A case with no intake or exhaust fans, cable clutter blocking airflow paths, or a side panel left off can raise internal temperatures significantly. We assess your case layout and recommend simple fixes — adding a fan, re-routing cables, or moving the PC away from an enclosed cabinet.
Software and background process causes
Cryptomining malware, runaway Windows Update processes, and poorly optimised software can pin your CPU at 100% continuously, causing heat buildup. We run a full software audit alongside hardware diagnostics to rule out malware and background process bloat. If the cause is software-only, this is covered under our malware and virus removal service. The National Cyber Security Centre publishes guidance on spotting this kind of unwanted software.
Slow PC — hardware causes we check
If your PC is slow but not running hot, the cause is often a failing hard drive (HDDs degrade gradually and become very slow before dying), insufficient RAM causing heavy paging to disk, or a faulty SSD. We run S.M.A.R.T. diagnostics on all storage devices, test RAM with Memtest86, and benchmark the system before and after repair so you can see the improvement. We test storage and memory as part of a full PC overheating repair West Bromwich.
Laptops and Desktops Need Different Cooling Work
Desktops usually overheat because of dust and failing case fans, and they are the easier of the two to put right. Laptops are tighter: the heatsink, fan and heat pipe sit in a sealed assembly, so a proper clean means removing the base and often the board itself. We also replace thermal pads on the memory and graphics chips while the machine is open, because those degrade at the same rate as the paste on the processor. If a laptop fan has become noisy or intermittent we fit a replacement rather than lubricate it, since a fan that stalls under load will simply cause the same problem again a few months later.
What We Test Before and After
Every PC overheating repair West Bromwich begins with a baseline: we log idle and load temperatures, fan speeds and clock behaviour so there is a number to compare against. After the service we run the same stress test again and show you the difference. A healthy desktop processor should settle well below eighty degrees under sustained load, and a laptop should stop throttling entirely. If temperatures are still high after a full clean and repaste, that points to a failing fan or a cooler that was never adequate for the hardware, and we will quote for the correct part rather than repeat the same work.
How much does overheating repair cost?
A full thermal service — disassembly, dust clean, new thermal paste and fan inspection — starts from £45 for a desktop tower. Storage or RAM replacement is quoted separately once we have confirmed the fault. All pricing is provided in writing before any chargeable work begins, and diagnosis is free if you proceed. Most PC overheating repair West Bromwich bookings are finished the same day.
