ASUS MX25AQ test – what can you expect after seven years of use?

Today we’re taking a look at a monitor that has already been in service for a few years. The ASUS MX25AQ has a QHD panel with a resolution of 2560 x 1440p on just 25 inches. You don’t necessarily have to do this, but if you like high PPI values, the 117 ppi would certainly appeal to you. According to Geizhals, the IPS panel was [...]


Slime in the GPU water block and white crystals in the radiator – about plasticizers, corrosion and the wrong materials | Investigative

Today’s case comes from the community and a lengthy investigation was necessary because there were actually two causes of the pollution at the same time. I will describe my process, the measurements and also the conclusions in chronological order and it also shows once again how important it is to know the connections and not just speculate [...]


We’re putting the pressure on: the new fan test bench is being built

Bearing in mind the adversities at the first attempt and the possible influence of the human factor, we have (hopefully) solved it better this time with expert support. Of course, there will be a detailed and transparent report on the exact development of the idea, the first prototypes and many empirical values, but today I don’t want to [...]


Philips EVNIA 34M2C8600 Review – A real price-performance recommendation?

Yes yes, the Philips EVNIA 34M2C8600. A name that goes down the gullet like liquid sunlight. All joking aside! The Philips offers the same first-generation Samsung QD-OLED panel that Alienware, MSI and Samsung themselves also have in their range. So we get a 3440 x 1440p ultrawide monitor with 175 Hz refresh rate and 1800R Curved. It also comes [...]


The big radiator material test: Radicooler, Richer-R and Magicool including purchase warnings and price-performance winners | Part 3

I’ve now reached part three and it’s time to briefly summarize the first two articles and, above all, to evaluate the reactions of the manufacturers, or rather their silence. As the case may be. Today’s test is about Radicooler (Qingdao YTeng Electronic Technology Co., Ltd.) and Magicool (Qingdao Magicool Electronic Technology Co [...]


Cooler Master MasterCase EG200 and Sapphire Radeon RX 7600XT Pulse Review – What is a current eGPU good for on a notebook?

It’s clear to everyone that, for the most part, a laptop doesn’t come close to a desktop PC. This is particularly noticeable when you want to play games or use more powerful applications. Here you can clearly see that performance and quality are already limited. A gaming laptop can help, but even here there are severe limitations in [...]


How accurate are my material analyses? Calibration is mandatory!

Of course, we remember my last measurements on the radiators and the respective material analyses, some of which showed different things than the customer (or manufacturer) actually expected. Apart from the fact that alloys are often not 100% homogeneous, major deviations should of course not occur. Yes, trace elements below one wt% are more of a [...]


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 [...]
