I've got the nateman_doo blocks installed, and I took some picures along the way.
First..I took out the motherboard tray, and stripped the board of the memory, GPU's, Raid card, and most of the loop. All that is left is the Mips VRM block and CPU block. It's been a long time since my board has been this empty....
This is a close up of the the Mips block. Notice how the block doesn't cover the entire VRM section. There will be a big difference in the components that the nateman_doo VRM block covers here.
These next two pictures are the back of the motherboard, and shows how the Mips block is connected. This copper bracket covers 12 things (I don't know if these are the DrMOS chips or the chokes). Since this copper is not connected in anyway to the copper that has the water running through it....I don't know if this is effective or not in cooling these items. As you will see soon, the nateman_doo block does not include anyhing that covers these items. Point to Mips for some attempt at cooling of these items on the back. Score: Mips 1, nateman_doo 0.
Now back to the front of the board, and I've taken the block off. See how there are 2x rows of 12 items (again...not sure if DrMOS or chokes)? Look back at the second picture...The Second Picture (Click to show)
and you'll see how the bottom row of these is sticking out from this block. It does not cover them all. The nateman_doo block DOES cover all of these items on the front of the board. Point for nateman_doo for more coverage of the front items on the board. Score: nateman_doo 1, Mips 1.
Since I've got the Mips block removed now...this is a good time to take some close-ups to compare the Mips block with the nateman_doo block.
In the picture below, the Mips block is on the left, and the nateman_doo block is on the right. You will notice right away the size difference. The nateman_doo block is enormous compared to the Mips block. It is also easy to see in this picture the difference in mounting approaches. The Mips block uses only two screws that are both on top corners of the block. Since there is only screws on two corners....there was always a little wiggle in this block. It is not secured on the bottom corners. Never liked this.
On the other hand, the nateman_doo block has screws in all four corners. The bottom two corners utilize the CPU mounting bracket screws. This holds it securely to the board. No wiggle. nateman_doo block wins the contest for ease and security of mounting the block. Score: nateman_doo 2, Mips 1.
In this picture, the nateman_doo block is on the top....Mips on the bottom. Again, you'll notice a massive difference in the size of these blocks. This picture also makes it easier to see the visual differences. I like how the nateman_doo block has black screws that blend right into the delrin top....instead of the shiny silver screws used on the Mips block. Point for nateman_doo for the screws. Score: nateman_doo 3, Mips 1
Piggy back time! Just to futher show the size difference in these blocks.
These next 3 pictures show the inside of the blocks.
First both blocks....side by side. Mips on the left....nateman_doo on the right.
...and now a closeup of the Mips block.....
....and a closeup of the nateman_doo block.
Now go back and look closely at the pictures above. Another big design difference is obvious here. The coolant channel is cut out of the black delrin top for the Mips block....but is cut-out of the copper for the nateman_doo block. And the difference in the depth of the channel is enormous. Th nateman_doo block is at least 50% deeper than the Mips block for the water channel. The Mips block has so little space in between where the fitting threads end and the copper plate begins....that I would be surprised if my flowrate doesn't increase some when swapping out these blocks. The nateman_doo block has a much more spacious water channel. Deeper and wider openings where the inlet and outlet are....and wider all the way across the block. Add to that the fact that the walls of the channel are also copper for the nateman_doo block....but are delrin for the Mips blocks....and I've got to image that more heat can be conducted by the huge hunk of copper in the nateman_doo block. Point to nateman_doo for deeper/wider copper channel. Score: nateman_doo 4, Mips 1.
Now...lets put the nateman_doo block on the board. I cut and placed some new thermal pad material. I used 1.5 mm for the top row of items...and 1.0 mm for the 2nd and 3rd row of items. This seemed to give the block the best contact across all three rows. I'm trying out some of the Fujipoly Ultra Extreme thermal pad
While I had the board this stripped down, I decided I'd go ahead and reapply the thermal paste for the CPU block. I'll be trying some Indigo Extreme in my final temperature test....but for now... I used my PK-1. Here is a shot of the old paste before I cleaned it up. Looks like the spread was decent and good contact was made. Lets hope this fresh application does well also.
Installed! Notice the two CPU block screws being utilized in a dual capacity now, and holding the bottom two corners of the VRM block. Nice.
And with the top back on the VRM block....
...and now with all the other items back on the board.
I've got everything back in and I'm doing a leak test right now. If all goes well I'll have it fired back up and running this evening. I can't wait to see if this block impacts temperatures and/or flow rate. More soon!
