be quiet! Dark Power 13 850W power supply in review – impressive efficiency, absolutely silent and with a decent performance

The be quiet! Dark Power 13 850W uses a high-end FSP platform that offers the highest efficiency, completely silent operation, and ATX v3.0 and PCIe 5.0 compatibility. The golden mean is tested today, because besides the 850-watt model, there is also the 750-watt variant and one with 1000 watts. Already the 850 watts are completely sufficient for [...]


Sharkoon S70 and S80 all-in-one CPU compact water cooling systems Review – Almost identical, but not the same after all

Today we welcome another brand in the highly competitive market of AiO complete water coolers, as Sharkoon now also offers three models. I have often praised Sharkoon when it comes to peripherals, and you can read how the two models with 240mm radiators fared in my test in the following article.

NVIDIA GeForce RTX 4090 and a design problem on the PCB – The 12VHPWR connector can be significantly cooler! | Pad Mod 2.0

Of course, you could have just soldered a few [...]


Twins? Thermal Grizzly Kryonaut Extreme vs. Kingpin Cooling KPx analyzed with scanning electron microscope and X-ray spectroscopy

Today we want to find out what is really in the two extremely expensive pastes and what philosophy is behind the respective mixture. And to spoil it a bit in advance: The biggest difference here is really only the color. Chic baby blue in the tube against a nice baby pink from the can and two prices reminiscent of certain products with the gold [...]
