Nateman_doo blocks cracked open.....
The VRM block doesn't have anything fancy or earth shattering inside. But it is so much larger than the Mips block, with so much more room for flow right under the in/out ports....that I really think this one may positively impact flow rate.
Little dirty underneath the cover....but the finish was still smooth and nice. And notice how perfect the O-ring groove is. Fits real nice.
Here you can see the o-ring and groove from a different angle. It's just about perfect.
Now...the chipset block is pretty darn complicated inside. In the picture below, the block is rotated just about like it will be mounted on the motherboard. The two circular shapes toward the top of the block are where the inlet/outlet are.
And this picture shows the bottom side of the block top. I never opened up my Mips block to see how the inside was milled....but this one sure looks restrictive. There just isn't much space at all where the port is that is directly underneath the CPU. The port that is underneath the USB connectors on the right side of the block...has a little more depth to it where the port is. Definitely will do some flow comparisons between the blocks to see if one of them has an advantage.
The groove and o-ring are again, impressively done. I kind of wonder whether or not the center divider will be able to keep flow directed down and around the block. With nothing to seal the divider other than the pressure of the top on the edges of the copper....it seems like this could allow some seepage over this middle line. I also worry that the lower PLX chip is not going to get a lot of flow....just because of the narrow opening into this little pocket. It is pictured in the lower right hand corner of the picture below.
Before I start testing the doo blocks....I'm going to get baseline temperature and flow measurements using the Mips blocks. But before I start that, I'm going to remove the RAM waterblocks. For two reasons. First...I'm interested in finding out how restrictive they are in my current loop setup. So I'll do a before and after flow measurement for the ram waterblocks. I've already seen that they don't really do anything at all for temps. The ram stays cool in the low 30's, even without watercooling. Virtually no difference with the waterblocks. But...I like the way the ram blocks look....so they will stay unless they are just killing my flow. Only way to know is to test with and without them.
Second reason....I have my doubts that the doo_blocks are going to play nicely with the ram waterblocks installed. Doesn't look like there is enough clearance for the way my current loop is laid out. And so that I can have an apple to apple comparison of just the Mips vs doo chipset block....I think I'll need to run the tests without the ram waterblocks.
Once I've run my baseline Mips numbers...I'll take those blocks off and take some more pictures of both blocks beside each other...so you can really tell the difference between the two. Plus, I kind of want to see the inside of the Mips block since I didn't open it before installation.
