BlockHeads: The Thread - Page 23

post #221 of 753
I was also thinking about your channels on the bottom of the mid block. I think you might be on to something here. Not so much a continuous channel like you have cut across, but an array of dimples.

I think an array of dimples like you have at the ends scattered throughout would help water get redirected up and back down into the base of the pins. I think it's that downward momentum of water that makes jets work well. But the problem with jets is the extreme restriction they create and then the rest of the pins don't get much attention.

Anyhow, just something I hadn't thought of before, and possibly something that may help. I think you want to force the water through the pins, but maybe letting it come up and get redirected back down is a good thing to scrub the bottom surface better..?

I was kind of aiming to reduce turbulence and help the water have an easier transition to the pin matrix. The area of the pin matrix is about .07"sq, the area of the ID of the barbs is .12"sq. With the channels I calculated about .085"sq so there is still a fairly decent impingment to help for flow uniformity.

Here's a couple of pics of the block mounted:







As you can tell by the pics this block has its own area code on the board.


I just finished refilling my loop and am idling at 19C in the bios, which isn't bad considering the ambient is 19C. Time to install windows and put some load on this puppy.

That's good!

I really like the lower mounts too, nice and clean that way

Edit: Here's some initial idle/load temps after a quick OC to 3ghz on stock vcore, room ambient is 20C:





Speedfan was calibrated to idle reading in bios

I went and made some popcorn while prime was running to let the temps stabilize, I watched them for another few minutes and they seemed to be pretty much dead stable so I just took the screenie. I'll do a longer average when I get a chance.

The rad was spitting out some pretty hot air by the time the load temp stabilized so I think that I can get the delta down a few degrees at least if I get a bit beefier fan to test with.

Very Nice.

The mounting system is extra clean.

Very nice! I'm highly impressed. Are you going to send a proto to Martin for testing?

Lucky Martin

I am the proud owner of a Cathar/Little River G5. Th Block is in transit so I'll post pics of this beauty when it arrives.

I wonder how it would perform on a Penryn
