Re: 4 cores vs 8 cores amd ryzen

If you're talking about "boost speeds" rather than "spreading the work load" it's also very similar between AMD and Intel. Many high end Intel motherboards allow CPUs to run (far) above their TDP as long as the cooling is sufficient. Look for example at HardOCP's review of the i9-9900K : At stock se...

Re: The marketing of quiet case fans is somewhat deceptive.

It's also important to notice that "quiet" fans typically also lack in ability to build pressure.
If your fans are to pull air through a dust filter you need stronger fans to generate a suitable air flow.
