The big radiator material test: Between promise, reality and the forbidden – Water Cooling tested more in Detail! | Part 1

No, I’m not going to test the cooling performance of radiators for PC cooling today, but I am going to take a closer look at the first six manufacturers and their current models to see whether they really do contain exactly what the marketing advertises and the customer buys in good faith in some cases. In the first part, I obtained [...]


NZXT Function 2 Mechanical Keyboard(s) in test – Can the second generation with optical switches and PBT double-shot keycaps attack the upper class?

With the Function 2 series, NZXT has given its mechanical keyboards an extensive makeover. Adjustable optical switches, PBT keycaps and 8000Hz polling are just the tip of the iceberg.

Brass instead of copper: Watercool reacts, but differently than expected

I have linked the relevant article again below, but today’s text is actually clear enough. In the Watercool HEATKILLER RAD 120-S Black I tested yesterday, I found simple and only average brass in the cooling channels instead of the advertised copper. Watercool reacted quite quickly after publishing the article and my video, but not in the [...]


Update with statement: Acemagic Mini-PCs infected with spyware and malware

We recently reported that malware was found in certain revisions of systems from the manufacturer Acemagic. As we had also tested these mini PCs and they were connected to my network, the matter was of course even more explosive.

Database of the best electrolytic capacitors – Are Japanese capacitors really better than Chinese or Taiwanese ones?

I’m letting my friend Aris have his say again today and would be delighted if you would also support his plans. What he’s testing is sound, but it’s really hard to make a name for yourself in this age of colorful YouTube videos and dangerous TikTok half-truths. And so today we’re sharing our reach again and I’m [...]


With the Thermal Grizzly Kryosheet, Arctic TP3 pads and cap nuts from an IKEA paper box against a graphics card hotspot | User Review

Today’s article comes from our community member big-maec and it shows how the community is also keen to experiment with various pads. The article will also show that sometimes it takes a little more work to really fix a problem permanently.

Ground on the wrong track: Why only certain power connector pins melt and we should rethink PCs | Part 1 of 2

Some things are accidental discoveries and are actually so trivial that nobody even bothers to question the current flows in the PC and, above all, to measure them. We only ever measure the 12-volt rails and are happy. But with connectors such as the 12VHPWR or 12V2x6 over 6+2 pin, the 8-pin EPS and the 24-pin mainboard connection, does exactly [...]


FiiO EM5 Earbuds Review- Brilliant earbuds with extreme depth, high addictive potential and a certain fiddly factor

With the FiiO EM5, I am testing earbuds today that are a little out of the ordinary. My thanks first go to the community for sending me the test sample, because the FiiO EM5 headphones are a very exciting product for audiophiles and music lovers who are looking for an exceptional listening experience.

UPRtek MK550T Spectroradiometer presented and in use – Upgrade of our monitor test setup and basics of measurement technology

I’ve been officially testing monitors at Igor’sLab for almost two years now. I started out quite rudimentary with a very cheap colorimeter, the SpyderX and a mixture of DisplayCal and the SpyderX software. Everyone starts small, of course. The whole thing then developed quite quickly and we gradually upgraded and managed to get [...]
