Our first blush with Koolance and Threadripper cooling came in December of last year when we reviewed the first version of the 400A-S water block. At that time, it placed in the middle of the pack when it came to cooling our overclocked Threadripper. Koolance's first version of its 400A-S water block was based on its design footprint from previous Intel based coolers. The first 400A-S was truly an Intel water block retrofitted to mount on to the TR4 socket footprint.
This new version of the Koolance 400A-S comes to us looking much the same as the first one did. Again, there are no Frag Harder Disco Lights or fancy see-through tops in order to see coolant flow. The new 400A-S is all business just like its predecessor. Dressed in basic black with a white Koolance "bowtie" again, it is not for those of you looking to show it off. Classy, but not showing off.
The 400A-S has a very diminutive profile as well. This could certainly give you a little extra room for fittings and bends when it comes to a solid install.
The finish on the top of the block is hard to get a good picture of. The cover to the top of the block is actually a metal sleeve that has seemingly been powder coated, and seems to be very durable. It actually has a grain to it that is very shallow, and you feel it with your finger nail. Certainly this will cut down on fingerprints.
We have talked above about the previous version of the block and I wanted to show you the two side by side. The first thing you will notice are the relocated inlet and outlet openings. Also the overall size has exapanded a good bit, and the shape has changed from a rectangle to a hexagon.
The hexagon shape continues over to the coldplate as well.
