I've been meaning to post it up but I have my UD5 (Rev 3.0) board fully under water (Northbridge/Sourthbridge/VRMs). My case is so much cooler now! I say that as I don't have any fans inside my case.
It did require some modding of the mounting systems on the NB/SB water blocks, as well as, a good deal of modding to get the VRM heatsink on but all is good now.
What I used:
but should be able to use (CHC-125) on the NB/SB if you prefer:http://www.performance-pcs.com/catalog/index.php?main_page=product_info&cPath=59_971_241_591&products_id=23414
NZL-V13B (4x) for the NB/SB Blocks:http://www.performance-pcs.com/catalog/index.php?main_page=product_info&cPath=59_346_203_478&products_id=22082
MVR-100 (140mm Heat Plate):http://www.performance-pcs.com/catalog/index.php?main_page=product_info&cPath=59_971_401_597&products_id=24497
Fujipoly Extreme System Builder Thermal Pad - 1/4 Sheet - 150 x 100 x 0.5 - Thermal Conductivity 11.0 W/mK:http://www.frozencpu.com/products/16878/thr-164/Fujipoly_Extreme_System_Builder_Thermal_Pad_-_14_Sheet_-_150_x_100_x_05_-_Thermal_Conductivity_110_WmK.html?tl=g8c487s1288
This Fujipoly is very brittle and comes apart easily so getting this sheet is nice for any mistakes and will match up to the 140mm heatplate exactly once you cut it down to size. The 140mm heat plate will need to be cut/grinded down to 100mm long and 11mm wide. If I remember correctly it's 140mm long (that's a given) and 14mm wide (might have been 17mm). You'll need to cut all four sizes off evenly to keep the MVR-100 centered onto the plate as there's just enough room to get that bad boy on top of the MVR's and into that narrow path where they lie. This is the ONLY MVR block that'll work on the UD5 as I've done A LOT of research into this. Also, the MVR block will only work if you modify the plate but there's no modification that's needed to be done to the MVR-100 itself. Also, the CHC-122 is very particular on what type of barbs you use on it. I had XSPC barbs but the threads went too deep and they wouldn't screw all the way down. You'll need shallow threaded barbs on these guys for them to work. I ended up ordering Koolance's barbs and haven't had a problem.
For custom mounting you'll have to visit your hardware store and pick up some nuts and bolts. I can tell you what sizes you'll need if you're really interested.An important note: I can't stress this enough!!! Don't and I mean don't mount any of Koolance's waterblocks that I mentioned the way that they describe it. The inside diameter of their plastic washer is a hair smaller than the outsider diameter of their screw head. I found this out the hard way. I had the CHC-122 on my NB for only a few days and then one day I was sitting at my computer and head this slightly plastic sound on the inside of my case and then a second later my computer turn off and I had a burning smell. I guess over the course of a few days the screw head managed to slowly work its way through the plastic washer that was holding it onto the board and popped the NB Waterblock off of my NB chip and then killed the board. I RMA'd the board and got a replacement. All is good now. I modified the heck out of the mounting system and made it heavy duty so that there's no way any of the parts are coming off of where they are now.Further Note: If you water block the SB you won't be able to use multiple GPU's. I only have 1 GPU so it's not a concern but slots 2 and 3 (below the top slot) will be blocked from the barbs sticking out of the top. If you're GPU's aren't that long then maybe you can get away with it but I have a 5870 and that thing is very long and ONLY fits in the top slot with the SB block so if you're using multiple GPU's then you probably won't want to water cool the SB. I did it just for the heck of it as it was getting quite hot since I don't have any fans inside my case and my NB blew up anyway causing me to have to redo everything so I said screw it and ordered the block as I initially didn't think that it would work but once I put a water block on my 5870 I had more than enough room.
