Koolance sent us their upcoming CPU block, the CPU-370, and that means two things: 1) CPU Block Comparison 2011 will kick off now that there’s a newcomer, and 2) you get a preview of the block!
From the most preliminary looks of it, it’s barely changed from the CPU-360. Same box, same great mounting system, same overall look, altered barb positioning, and just a slight change in text positioning, size, and model number.
Open it up and the changed barb positioning shows a slightly different internal geometry–lower restriction is a distinct possibility. The base and midplate appear unchanged from CPU-360 rev1.2 with the same thickness, width (fin and channel), and positioning. However, the channel depth may be slightly deeper, resulting in more surface area as well as less material between CPU block and the flowpath. Placing a straight-edge over the assembled block’s base shows a significantly more pronounced bow–this will likely result in improved contact and is likely due to the changed internal geometry. Improved contact and less ‘underfin’ can make a big difference in performance, so as soon as testing is done, we’ll see what these changes will mean for users.
Looks like the CPU Block testbed needs to be fired up–have some interesting changes in store for the 2011 Comparison.
