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. It shows how air moves, not how hot parts get.

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
  • Ready-made layouts to start from
  • Graphics card sizes, CPU coolers and AIO radiators to swap in
  • Finer 10 mm and 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.

Look for Create report under a result in these calculators:

A Power Supply Report for a sample repair shop, with its logo, the customer's name, a quote number and an 800 watt recommendation
A real Power Supply Report, made for a sample repair shop.

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.
