The fan is made by ADDA, like on all of the other In Win products I have reviewed. This time, however, it uses ADDA’s Hypro bearing – a type of fluid dynamic bearing – as opposed to a plain sleeve bearing. These types of bearings are great, as they are quieter than ball bearings, but more reliable than sleeve bearings.

Not really... Hyprobearings aren't fluid dynamic bearings, at least not from ADDA, they're just modified sleeve bearings. I have had many 45mm and 52mm ones fail on very old Radeon and GeForce graphics card the same way ADDA sleeve bearings fail (and soon after found no lubricant at all in the bearing). But if the fan spins so slowly at low loads it might have no problem lasting.

The secondary side capacitors are all made by Teapo. They aren’t as bad as the likes of Fuhjyyu and can hold up OK if given good cooling.

So your view of Teapo has changed?

I fixed that bit up. I'm not gonna knock anything more off for it, though. A bit of extra lubricant is usually all it takes for these larger fans to do OK.

Not really. I've always classed them a notch above Fuhjyyu, and I've always know that they can do OK if you get a good batch and don't stress them or use them on the 5vsb. But I still don't have high hopes for the caps this unit. I recapped the two on the 5vsb and the 3300uF 16V cap with Panny FRs before I put this unit back together. If it hadn't been for the use of Teapos, it would have got a 10/10 and Gold award. It's also worth noting that, when I opened the unit up a few minutes after the load testing, the 3300uF was too hot to touch.

It didn't burn your fingers, though? Since too hot to touch could either mean above 60*C or above 70*C (discolorating and the point where it burns your fingers). And that secondary heatsink could definitely be leaps and bounds better.

Only those???

I think the MOSFETs chosen would dissipate only 6W or so under full load in this unit. My guess is that using a top-mounted fan with the angled-top-fins heatsink inhibits the flow of air across the heatsink surface.

The on resistance of MOSFETs is as important as the current rating and should be mentioned.

Compared to its 80plus bronze certified cousin (the IP-S400EQ3-2), this unit has a slightly reduced 3.3V and 5V capacity (90W vs 120W), and a slightly increased 12V capacity (390W vs 300W)

I don't think either of those changes are slight - they're 75% and 130%, respectively, of what they were.

No, but it would have if I had kept my finger there. Either way, I don't think it's going to do the cap any favour. It is a Teapo after all.

Yeah. Those are the only ones that seem to get stressed. The others didn't even feel warm, which tells me that they are not getting heated up by other parts, nor are they being subjected to a lot of ripple.

I like Teapo.

Uh-oh...
