RICHER-R copper radiator 120 mm
I bought the second radiator in Germany from amazon.de. But anyone who thinks that this would protect you from a total failure is very much mistaken. Amazon’s marketplace is also quite full of sellers of inferior products. In this case, it is a so-called “Ashata Store” that is offering this lead bomb for sale. The radiator initially made a pretty decent impression, except for the coating. Especially as the radiator is visually almost indistinguishable from a genuine Magicool product and the packaging looks completely the same, right down to the little screw bag. I asked about it and was told that it really is an unlabeled Magicool product in the form of the MC-RAD120G2. Let’s see…
Now let’s let the manufacturer provider have his own say before I comment on this:
Pre-chamber, inlet and plumb bob
Let’s open the cooler at the pre-chamber (tank). As with the Radicooler, the solder joints of the cooling channels are neither oxidized nor scaled. The solder is circumferential and very well distributed. The bottom line is that you can leave it as it is, although the best and cheapest way to achieve this quality is with lead solder and lower temperatures. But we’ve just been through that…
And I was proved right. Here too (apart from the non-homogeneous mixture) we find the mixture Pb65Sn35, i.e. lead with only 35% tin, which is also equivalent to a sales ban! And this is also done here over a very large area and almost looks like the same, generous wave solder bath. This is incomprehensible insofar as Magicool can also use lead-free, as I will show in a moment.
The walls of the pre-chamber are also without complaint, because CuZn40 (I’m rounding this up for reasons of goodwill) is really good brass. In contrast to lead, this is the material in the deep green range.
But now we come to a certain point where the wheat is separated from the chaff, namely at the threaded inserts for the fittings, which were soldered into the chamber beforehand, often by a supplier. With a lot of 63% lead in the solder (most likely Pb65Sn35), this product must definitely not be sold in the EU, as it is a blatant violation of import regulations and RoHS requirements! And I will repeat this ad nauseam: We are not talking about microscopically small quantities here either, but when soldering, the entire cavity around the insert is also filled with solder, in this case lead.
The soldered thread insert is made of white brass with almost 50% zinc by weight. This is just before the porous step.
Cooling channels and cooling fins
Now we come to the cooling channels and the fins soldered to them. If you cut the whole thing open, you get the usual picture.
Channels made of soldered-together folded tubes here too, but the copper content is extremely high (as with EKWB) The cooling channels are therefore CuZn10, which I would not have expected here. If it hadn’t been for the lead… Oh well.
The slotted cooling fins are made of pure copper, because brass would break more easily here, as it would also be much more brittle due to the zinc.
Frame and screws
With the usual addition of around 14% chrome, the frame with the threaded holes for mounting is very durable.
The nickel-plated screws, on the other hand, are made of pure, unalloyed steel. In detail, the analysis looks like this:
Summary and interim conclusion
The radiator also contains far too much lead. This means that sales in the EU should be stopped immediately and I will inform Amazon of this. Unfortunately, the Marketplace provider is playing dead. I can only hope that everyone will refrain from buying these products. If you do, then it’s better to buy the original, but we’ll come to that in a moment.
