3D PC Airflow Simulator
Test a fan layout before you spend money
Build your case in 3D, add fans, and run air through it. Each run shows your case pressure and how much air reaches your graphics card and CPU cooler.
Pick your graphics card and CPU by name, such as an RTX 5060 or a Core Ultra 5 225, choose a load from gaming to full load, and the simulator fills in the heat each one gives off. Set how warm your room is, and each run shows how hot your graphics card and CPU get, and how warm the air around them is.
Flip one fan or change its speed, run it again, and compare the two layouts side by side.
- Cases from Mini-ITX to a full tower, including the common ATX mid-tower and real Corsair, NZXT, Lian Li, Fractal Design and Cooler Master models
- Graphics card and CPU temperatures, and the air going into them, leaving the case, and inside it
- Ready-made layouts to start from
- Graphics card sizes, CPU coolers and AIO radiators to swap in
- Finer 6.7 mm detail, and builds you can save
The full simulator comes with Pro, and one case type is free as a preview you can try now.
Calculator reports
Hand clients a report with your name on it
Turn a calculator result into a clean report you can print or save as a PDF. It lists every detail entered, your notes, and who the report is for.
Add your business name, contact details and logo once. Your browser remembers them for next time, and they're never sent to us.

PC Reporter Pro
Get to the bottom of crashes that keep coming back
PC Reporter is our free Windows app for hardware details and crash evidence. Pro makes its Crash Trace tab far more useful when the same problem returns.
- Keep up to 100 incidents for a full year, instead of 10 for 30 days
- See what your crashes, freezes and restarts have in common, like the same app or stop code
- Put your business name, contact line and logo on exported incident reports
To sign in, select Get Pro in the app and enter the license key from your receipt email. The same key works in PC Reporter and in your browser.
ISP Watchdog
Prove your internet isn't what you pay for
ISP Watchdog runs silently on your PC and logs every outage, slowdown and lag spike around the clock. It compares them with your plan's broadband label.
Each month it tells you, in plain English, whether you got what you paid for. When you didn't, it builds the evidence and the letter.
- Outages placed on your provider's side or yours, by checking your router every five seconds
- Speed tests through the day and evening, measured against your label
- A one-click evidence pack, and letters for a credit, a technician or a way out of your contract
The download opens on an example month. Sign in with your license key to start watching your own connection.
