I'd certainly assume that dodgy looking device in that last photo to be dangerous. What is it?

Water cooling block?

The water cooling part is right.
But this is an extra secret feature that serves multible purposes within the water cooling scheme, I can list 3 off the top of my head, to improve the water cooling.

Cheers, Finn Hammer

Maybe one of the additional ways it cools is via evaporation? Maybe even forced air + evaporation? tongue
"Black body radiation" starts with a B.
Could you tell us if these are ceramic or plastic (they look like plastic but just to make sure) and also take another picture at a slightly shallower angle?

I believe he is using the IGBT substrate as part of the waterblock by having it sit directly on top of the water channels, with the perimeter sealed by an o-ring.
No more wasting delta T on thermal junctions, just cold water on the back of the IGBT.

Edit:
I knew I've seen it somewhere

Jack, that´s close enough, just wondering now, how to deliver the cookie.

The word we wanted to hear is baffle. It is a baffle.
This baffle is embedded in an alluminum plate which forms the basis of the manifold.
The water enters the big rectangular holes on one side and have to pass the maze channels to exit the row of holes on the other side of the block.
The maze shape adds 2 features: first it creates resistance to the flow of the water, series resistance makes the flow equal in each channel.
It also forces turbulence to the flow, facilitating heat transfer to the liquid.
Third: The plastic insulates radiated heat from reaching cooling backplate made from alluminium.

Isn't that being "economical with the actualité"?

Don't be modest! That's the one that took the windows out suprised

FX shuffles feet nervously, Could be, I'm sure it would be considered off topic to discuss it further here wink

Pictures taken with Casio EX-FH20 (High speed camera) while down south. All images are direct from the camera, No photoshop has been used. Just me not knowing how to use the camera!
