Disclaimer: I am far from an expert in these matters. Follow these instructions at your own risk! I recently bought and installed the
EnzoTech EVX-58 Chipset Waterblock for my EVGA x58 (132-BL-E758-A1) motherboard. I couldn't find any reviews for it when I bought it so I figured I'd give my 2 cents for others who may be considering this waterblock.
Removing EVGA's heat sinks from the MB was relatively painless and went fairly quick. They didn't seem to use any thermal glue on the chips (just paste and heat pads) so they let go without much force. In fact the most difficult part of the whole processes was removing the North Bridge fan plug, that thing was really on there!
The waterblock instructions said to remove the old thermal paste and thermal pads (if they weren't already). It came with its own thermal pads and Arctic Silver Ceramique Thermal Compound. I used some Arctic Cooling MX-2 instead of the Arctic Silver since I knew that was not electrically conductive, I'm not sure about the Arctic Silver Ceramique.
The instructions said to place the Thermal compound on the North and South bridge chips and put the heat pads on the waterblock which would cover the VREG/MOSFET. It also had what it called a sponge which was a square frame (center of it cut out) around the North Bridge which I later ended up removing which I'll explain later. Once the waterblock was in place it came with some screws with springs on them to hold it in place.
After completing the water loop it seemed to be doing its job. I checked my VREG temp in ELEET and it was sitting at around 50C. However,
I then went into the BIOS and I noticed my North Bridge temperature was extremely high, like 90C! I immediately shutdown the computer knowing I'd have to reseat the waterblock. I already had an idea what the problem was, that "sponge" seemed a little thick to me when I installed it.
After I got everything unhooked and drained of water I took off the waterblock and removed the sponge. I also cut up the old VREG thermal pad and placed little strips on the small chips surrounding the North Bridge, similar to how EVGA had their North Bridge cooler set up. I added a bit more thermal paste at this point and re-attached the waterblock. This time around I used the screws that held the EVGA heat sinks onto the board instead of the ones that came with the water block. The reason is the ones that came with the motherboard had these nice thick rubber washers on them and I felt a little more comfortable tightening them (still not too tight!) than the ones that came with the waterblock.
After reseating the waterblock the temperatures seemed much better. My VREG and NB now sit around 40-50C under load.
Quick Recap: - Don't bother with the sponge, it seems to be too thick to allow good contact with the NB
- Cut strips off the old VREG thermal pad to use on the small chips surrounding the NB
- Use the screws that you took out of the NB that have the rubber washer, not the ones that came with the waterblock
- CHECK YOUR TEMPS IN BIOS IMMEDIATELY to make sure the waterblock is doing it's job
