Avoid mistakes: How to use pads like the Honeywell PTM7950 or other phase change pads correctly! | Instructions and practice

In recent years, phase-changing thermal interface materials such as Honeywell’s PTM 7950 have increasingly established themselves as a high-performance alternative to classic thermal pastes – especially where permanent, stable thermal coupling under high mechanical loads is required. Despite their basic user-friendliness, however, the [...]


Local hotspots on RTX-5000 cards: When board layout and cooling design don’t work together and a pad mod has to help

Recently, several current graphics card models in the RTX 5000 series, including the RTX 5080, 5070 (Ti) and 5060 Ti in particular, have shown thermal anomalies in the area of local hotspots on the back of the board in my tests. These affect cards from major board partners such as Palit, PNY and MSI as well as variants from other manufacturers [...]

Anycubic Kobra S1 Combo 3D Printer Review – Innovation or just imitation?

At the end of last year, we took a look at Anycubic’s answer to the popular Bambu Lab A1, so it was only a matter of time before another competitor to the P1S was launched. Because what is being targeted here is obvious in more than one place. So let’s take a look together at what this CoreXY printer has to offer. If you want to read [...]

Shin Etsu MicroSi X-23-7921-5, X-23-7783D and G7762 Thermal Paste Review – Large particles for large numbers and large problems

Today I’m testing the Shin Etsu MicroSi X-23-7921-5 , the MicroSi X-23-7783D and the MicroSi G7762. Once again, my thanks go to the community for the kind procurement. All three pastes are actually not that bad, but they show the typical problem when the manufacturer tries to generate great values. That’s why I’m using the whole [...]


High memory temperatures on many RDNA4 cards and what exactly is behind them – Cause research and background information

As I was also surprised by the high memory temperatures on many (but not all) of the RDNA4 cards I have tested so far and have received various inquiries from readers, this was the trigger for me to take a closer look at the problem. The reason was as trivial as it was surprising, but it is also a good reason to take a closer look at the basics [...]


Faulty chip surface ex works on a Radeon RX 9070XT, extreme hotspot temperatures and research into the causes of pitting (Update #2)

As part of a reader request, I was given a new PowerColor Radeon RX 9070XT Hellhound for analysis, in which unusually high GPU and hotspot temperatures were observed under load, which suggests an uneven or locally disturbed thermal coupling of the GPU die. Despite proper reapplication of a high-quality PTM pad and additional thermal putty instead [...]
