The Cooler Master GA271 Review – A real 1440p gaming price breaker or just a second monitor for the home office?

Today the time has finally come, I have the first VA panel in my test. This means that I have now tested all the current display types. Introducing the Cooler Master GA271. I wouldn’t normally take a look at this monitor, but the RRP of 159.90 euros immediately got me interested. A monitor with a resolution of 2560 x 1440p and 100 Hz refresh [...]

Smoldering Headers on NVIDIA’s GeForce RTX 4090 – New Insights, Measurements and (Un)known Causes of the 12VHPWR and 12V-2×6 Issue | Update

Today’s article is the result of several months of laboratory work, extensive measurement series, development work, and constant cross-checking. The matter of the 12-volt connectors is unfortunately so complex that I had to look for a new approach to complete the picture. And no, there isn’t THE one cause, but always a causal chain of [...]


Synology DS923 NAS in practice test – Very good all-rounder with many advantages, but almost nothing works without extensions

Synology’s DS923 has already been on the market for a year, whereas they already took their time with the DS920. By the way, long product cycles are more of an advantage than a disadvantage in my opinion, because the product and software mature without blind haste. With an AMD Ryzen R1600 as the main processor, four drive bays, two M.2 slots [...]


Bambu Lab P1S AMS Combo 3D Printer Review – Raising the Bar Again

I think that if you’re even a little bit involved with 3D printing, there’s no way around some of the manufacturers. In the past, Creality and Prusa were clearly the sole top dogs, but they are no longer alone there. Thereis a lot to say aboutthe P1S and Bambu Lab ,so let’s start right away and put some more pressure on them [...]


Order trick with Amazon: How the 1-day delivery of several scarce items with Prime then works after all (self-test)

The NAS article actually planned for today has to wait until next week, the delivery delays for certain components has unfortunately (once again) put a spoke in my wheel. But at least a nice workaround fell in front of my feet, with which you can also beat Amazon a bargain with your own stock. Sure, the whole thing is no big deal, but with a [...]


Different Noctua NF-A12x25 PWM Case Fans in Review – When database tests, user experience and re-tests differ from each other

The Noctua NF-A12x25 PWM has been around for what feels like an eternity, and of course such a product may be technically improved over time, or the tooling is changed on a regular basis, or at least various details are changed. There was already media attention in 2016 about the (ultimately non-existent) differences between the Chinese and [...]


DIY Modding: White Edition for small money – We paint a graphics card

During the review of the BeQuiet Shadow Base 800 FX, I simply felt the need to install a white graphics card. Since no adequate model could be found in the short term and I had a rough idea of what the whole story should look like, we did it ourselves without further ado. And even if this is not the holy grail of knowledge today, we can all [...]


igor’sLAB continues to upgrade: On the hunt for (false) elements and measuring the impossible – Keyence VHX7000 and EA-300 in daily use | Issue 1

You can invest a lot of things for and in something. Time, energy and, of course, a lot of money. But if you take the latter in hand, on the one hand to save time and energy, and on the other hand to test or uncover things that your normal (media) competitors can’t, then something like this is well worth it. After all, I have two mainstays [...]
