Alphacool Eisblock Aurora Acrylic GPX-N RTX 4090 FE Review – Significantly cheaper than the rest and a real contender!

Today I’m testing the Alphacool Aurora Acryl GPX-N RTX 4090 FE Eisblock, the third water block for NVIDIA’s top-of-the-line model, and the picture is getting more and more solidified as to which cooler design is really good and usable. And this is where it gets really exciting: Alphacool’s cooler costs a whopping 90 to 100 Euros [...]


EK Quantum Vector2 FE RTX 4090 D-RGB GPU Water Block Review – Acetal instead of Acryl for the NVIDIA GeForce RTX 4090 FE

Today we are going to round two with the EK Quantum Vector2 FE RTX 4090 D-RGB. A GeForce RTX 4090 FE is per se well cooled and the original cooler is actually also perfectly sufficient. So one would hardly have a valid reason as a buyer to disassemble and rebuild this collectible. Well, almost none, because the weight and space requirements of [...]


Slime in the tubes including a long-term test – Particle filter, do-it-yourself filter and the follow-up costs of PVC tubes

No, it is not a contradiction, but transparent plastic tube (usually PVC) is cheap to buy, but really expensive in follow-up costs. Who can, prefer to go for hard tubing or such nice things as EPDM or Teflon, but there are also situations where you end up torn as to what it should be. And many a person is afraid to take anything other than PVC [...]


Heat conductive paste against food, cosmetics and various lubricant – with expected unexpected results | Practice

Groundhog day, again and again. Today, I’m pushing up a classic review for you to enjoy on a cold winter Sunday, and it was a very interesting experiment. Already 12 years ago I had tested various things up to the adhesive cream for the third for their thermal conductivity. However, this time I have modified the classics a bit and included [...]


EK Nucleus CR360 Lux Review – Stylish lighting, but also good cooling?

The last AiO water cooler we tested here from EK was from the “Basic” series and came entirely without lighting. However, it is not possible to do without RGB completely, because the new “Nucleus” series brings RGB back to the foreground. In the following article, we will find out whether it is possible to deliver a good [...]


Endorfy Navis F360 CPU AiO Cooler Review – Retest of the big brother

Towards the end of last year, we first had the 280mm variant of this AiO water cooler in review, and now the manufacturer asked me to also include the version with a 360mm radiator in the rankings. Recently, a decent overall package of cooling performance, workmanship and warranty length was put together, but now the CPU temperature is to be [...]


Overview and comparison of all tested CPU air and AiO water coolers

To be able to cover the higher TDP classes of processors in the future, I upgraded my testbench from a Ryzen 5 3600 to a Ryzen 9 3950X. However, so that the compact or budget coolers are not completely overtaxed, testing is done in three stages. This article serves as a reference and basis for future comparisons so that tested air and water [...]


Corsair Hydro X Series XG7 RGB 40-Series GPU water block (CX-9020019-WW) Review – NVIDIA GeForce RTX 4090 FE deep chilled

A GeForce RTX 4090 FE is not only expensive, but also still highly sought-after. The original air cooler is almost oversized and as a buyer you hardly have a valid reason to disassemble and rebuild this collector’s item. Well, almost, because the weight and space requirements of this card are the other side of the coin, although the board [...]


DeepCool AK400 Zero Dark Plus Review – Blackout for the Mid-Range

A good half year ago, we already had the normal variant of this cooler in review, and now another model in completely black coloring and a second fan follows. First, a question on my part: Should not “Zero Dark” actually be a completely white version of this cooler? We might not find the answer to that today, but at least I can test [...]
