Material analysis in detail
Let’s start with the heatsink. This is made of pure electrolytic copper and has been nickel-plated very thinly. You can still see the tool marks quite clearly. But that doesn’t really matter, because there is also…
… the thermal paste. Unfortunately, we only find rather low-priced zinc oxide ointment, sorry paste. Yes, it does the job and it’s not too oily, but it’s not really plump.
Now we come to the thick gray pads, where a rather soft mass is used. With an aluminum-oxide-silicone mixture, these silicone pads are lower middle class.
The heatpipes are made of nickel-plated copper and hide no secrets. Just the usual.
The inner part of the frame, which carries everything, is made of an interesting alloy. The 4000 aluminum is a so-called wrought alloy, which delivers excellent results at both low and high temperatures. The addition of silicon increases strength at the expense of overall ductility. The addition of nickel reduces thermal expansion while increasing mechanical strength, although there is a susceptibility to pitting corrosion. In addition to the high tensile strength of all aluminum alloys in the 4000 series, the reduced thermal expansion is the decisive factor.
The black-coated backplate is made of pure aluminum, except for the foil glued inside.
The clamping cross of the GPU is spring steel as an iron-nickel alloy.
That concludes the analysis part and we finally come to the benchmarks.
