With the Silentflux, a CPU cooler that combines the still current principle of heat pipes with water, Noiselimit went its own way from 2007 onwards. Another reader test comes from the community, which puts the interesting and unusual concept to the test.
The somewhat different CPU cooler in the reader test
In his reader article “Silentflux – Who am I?” the community member “andi_sco”, who among other things also has the popular “retro hardware picture thread” in the retro corner of the ComputerBase forum initiated the Noiselimit Silentflux and gives its assessment of the cooling concept.
A so-called bubble pump is used works differently than a so-called thermosiphon cooling by means of a gravity pump.
The CPU heats the existing liquid, it rises in the form of bubbles, cools down in the radiator and ends up back at the CPU.
Compared to the boxed coolers from Intel with a copper core that were common at the time, the Silentflux, made entirely of aluminum, is a real lightweight. While the boxed cooler weighs 446 grams, the Noiselimit Silentflux in the ATX version weighs just 313 grams.

Noiselimit Silentflux The test system included an Intel Pentium E2140 made in 65 nm (“Conroe”) with two times 1.6 GHz and 1 MB L2 cache, 2 GB DDR2 main memory and an Nvidia GeForce 7300 LE graphics card with a G72 graphics processor.

An ASRock G31M-GS with LGA 775 socket served as the basis for the test setup. A big thank you also goes to the community member “jumpin”, who made a large part of the hardware available.
