4. The Real Talk

About Hardware Stress

GPU tests push your hardware hard. Usually it's fine, but sometimes:

Your PC might slow down
  • • Other applications may lag during tests
  • • Mouse movement might feel sluggish
  • • Video streaming could stutter
  • • System UI might become less responsive
Things might get hot
  • • GPU temperatures can reach 80-85°C
  • • CPU may also heat up from overhead
  • • Laptop surfaces might become warm
  • • Thermal throttling may activate
Fans will spin up loud
  • • GPU fans may reach maximum RPM
  • • Case fans will increase speed
  • • Laptop cooling will be audible
  • • This is normal and expected
Rarely, existing problems might show up
  • • Unstable overclocks may crash
  • • Failing hardware could exhibit issues
  • • Driver bugs might surface
  • • Power supply limitations may appear

No Guarantees

CZNull comes "as is". We can't promise:

  • Perfect accuracy
  • It'll work on every system
  • Zero bugs ever
  • Your hardware stays perfect

5. Not Our Fault

If something goes wrong, we're not liable for:

  • Hardware issues
  • Lost data
  • Downtime
  • Money problems
  • Any other bad stuff

Use at your own risk. Seriously.

6. Our Stuff

Everything on CZNull (logo, code, text, etc.) belongs to us or our partners.

Don't copy, sell, or remake our stuff without written permission.

7. Don't Do This

Never use CZNull to:

  • Break laws
  • Hack or attack
  • Spread viruses
  • Mine crypto
  • Steal data
  • Copy our service

Just be a good person, okay?

8. You Got This

If someone sues us because of something you did, you'll help cover our costs. Fair?

9. Legal Stuff

These terms follow the laws where CZNull operates. If we disagree about something, we'll try to work it out through arbitration instead of court.

10. If Something's Invalid

If a judge says part of these terms doesn't work, we'll remove just that part. Everything else stays.
