Well, after almost two months, the guys at PCBox have finally brought me the H60, and luckily they respected the price, because it has gone up to more than 80€.
My impressions:
Performance
Well, with an i3, don't expect it to be a stove, but here are the screenshots, first at idle and then full.


The fan is set practically to the minimum from the BIOS, and the pump at full speed. I'm not sure if it's advisable to regulate the pump or keep it at maximum always. I say this because it might be bad for it or something like that, because in terms of performance and noise it's good.
The room will be around 25ºC if it reaches that, but we're not going to get too hot even in the middle of summer at around 30ºC that it can be here.
Sound
Well, the first test was very disappointing, I didn't notice much improvement over the normal heatsink and that's low profile. The fault lies with the fan that comes, and more if it's at full speed, but even at minimum it doesn't sound good, although perhaps it's that it didn't come properly. I put the one that came with the box, a Silverstone and there's no comparison. This bucket hasn't been this quiet for a long time, since I had the E5300 with a Scythe Shuriken B that didn't work for the i3 because of size and the placement of the socket next to the graphics card.
Assembly
Simple, more than most heatsinks... except that I have a very small case and the tubes aren't very flexible.
Yesterday I assembled everything in a configuration that I thought was good, although one of the elbows was hitting the graphics card a little. I went to turn it on and after a few seconds I lost video. I noticed that the part where the elbow of the tube hits the graphics card is where the card has one of the screws to fix the heatsink, which goes with a spring, so when you press it the heatsink stops making contact with the GPU.
Today I spent some time looking at similar assemblies on the internet, and finally I found a less forced position, I'll show you the photos in the branch of 'Photos of our PCs'.
And that's all. It will have to stay like this for a season, at least until after Christmas, because I had a car breakdown that cost me a lot. Maybe later I'll get an i5, although I don't need it, but you know how this goes ;D.
