I think the hotter it gets the more power it consumes.

I have seen very strange results over here, when I measure with my power-meter it is about 350 to 370W depending upon room temperature.
I have two power-meters, both give the same result within a few Watt.
When I measure the AC current with my Fluke clamp-meter it is 2.28A * 230V = 525W.
I don't understand how this is possible, the Fluke is brand new, it must have something to do with the power factor.

I'm not measuring directly at device. I measure whole building consumption at meter. Because I have solar PV I measure generation (by counting meter LED impulses) and consumption with a current sensing clamp (can then calculate net import/export). Accuracy of current sensing clamp is +/- 3%, but that is the same regardless of what you are measuring.
Regardless of all that, it is a significant decrease in power usage

I'm thinking about having a totally new case made where I can put the four blades together with a PSU in.
At the University where I used to work, they have a large mechanical workshop, when I ask these guy's they will do it for me.

I'd be interested if they want to make a few to earn some beer money :-)
I will ask them, but these things take some time.

And the numbers are in. Both new and old A2 minis running with one blade at 1280Mhz and one at 1200Mhz.
Old silver A2 Mini: 388W
New black A2 Mini: 263W

New black A2 Mini: 263W
Wow! That is even less than expected.
Maybe it has something to do with the power-meter it could be sensitive to the cos-phi.

Guys, the new A2MINI is from a new factory, the previous seriously fucked up and pissed off not only you guys but us as resellers and innosilicon themselves .
Innosilicon was pursuing for compensation from that factory, but was not successful.
But what is important is that you guys get the shinny new A2MINI now, enjoy.

That is true, I will certainly enjoy it!

The case is much better than the silver one BTW. I've asked MinerEU if their supplier can supply just a case. Then I can transplant silver one into it

Just backing up the SD card, so I have a nice clean one to build as I like it for both machines. Then I will do a power check. I have ordered another Scythe fan, thank god for Amazon Prime guaranteed next day delivery

Nice pictures, inside is a little bit dark though.
The heat-sinks seem a little bit different.
Does it consume less power with the ATX PSU?
I still have one spare Scyte fan, this is the first thing I will change.

Ok, maybe it is policy to put in one good and one lesser blade. Who knows.

Sorry for bad pictures

No that makes no difference. In my 1st one I had taken my blades out to put MX-2 on, when I hooked them up I connected them to the controller differently. I then had to swap the frequencies in cgminer

Yes my first one reports 432 and 428 cores. This new one is showing 432 and 431. My first one I can run one blade at 1280 and the other at 1200 with a reasonable amount of hardware errors. This one seems to be the same, one blade performs better than the other. Temperatures are better, simply because the air flows through the case better. I'll take some pictures shortly and get them up.
Maybe the difference between the blades has something to do with the controller.
I will try to exchange them on the controller to see what happens.

Blades are similar, haven't counted the chips. Scripta is reporting 432 cores on each so I guess they are still 8 chips.
At least both your blades are ok. My current A2 gives 432 for the first blade and 422 to 424 cores for the second.
The second blade is also much worse with respect to max. clock freq. and hw errors.
