EnzoTech SCW-1 Installation and Performance


This block uses a special back plate for LGA775 processors that requires motherboard removal.  Once you've got the board removed, you can simply install the back plate.  If you plan on leaving it attached to your motherboard a while; use the tape to secure it in place.  You can then re-install the board without worrying about the plate coming lose (LGA775 plate has long studs that prevent it from coming out of place).  Once the board is installed you can apply the thermal paste of your choice and screw on the spring-loaded nuts.  The directions state to tighten these evenly, but fail to mention how tight.  We made like Spock and were logical for a minute and tighten them up until we were satisfied.  The block was removed to check for an even mount, thermal paste was re-applied and we re-mounted the block once again.

You may notice that we didn't use the included hose clamps, and instead opted for the sleeker spring clamps from the original 3D Mercury Pro system.  The clamps EnzoTech provided certainly are better at preventing leaks, but we wanted to use a clamp that was as shiny and classy as the block itself.

We swapped out the Gigabyte block for this block and installation took about 30 minutes to take the system apart, pull the board, remove the old block, recover some fluid, put this new block in the loop and reinstall everything.  If you are setting up a system for the first time, you won't have to worry about removing the board and this will save you a bit of time.


Test System & Info:

Although not the fastest system we have around at the moment, we used the following test rig for testing out the Enzotech SCW-1:

To heat things up we ran two instances of Folding @ Home on the system as well as 3DMark 2006.  Temperatures were taken with Core Temp after at least 2 hours of running at full load, and after 1 hour of returning to idle.

For some reason, the E4300 did not like this board and was only able to clock up to a mere 2.53GHz stable.  Other chips have made much higher FSB on this board, but no matter what we did, we were limited to a 282MHz FSB.  We turned up the core voltage to 1.41v to help generate some heat.  Please keep in mind that Core Temp often records temperatures that appear much higher than many other software programs.  Bear this in mind and please only compare performance numbers in this review only.

To get the numbers in the chart below, we simply averaged the two cores.


When compared to the stock Gigabyte WPBC1 block, the Enzotech block wins by 3.5C at stock speeds idle, and increases to a 4.5C under load.  When we turn up the heat and overclock the processor, we seem the gap is 3C idle and 3.5C at full load.  I do believe that we are seeing some limits of the 3D Mercury Pro system as the radiator perhaps is a weak point on this case.  Regardless, this is a reference point and we see the EnzoTech Sapphire SCW-1 does indeed beat the Gigabyte block by a decent margin.



The EnzoTech SCW-1 in its current state is a decent block for your next watercooling project, but as we stated earlier, this block may still be up for another revision or two.  In its current state, it beat a mainstream block for a well-known company and in the future we hope to compare it to other blocks from other companies.  It's been a while since we've been heavily into watercooling, but Quad Core CPU's have once again spurned on the need for better cooling and Enzotech should be considered.

This block looks great, performs well, and will hopefully be priced to move here in the North American market.  This market is a tough nut to crack as people are quite loyal to the likes of Danger Den and Swiftech.  We'd like to see this block compared to some of their products in the future to see how it stacks up across the board.


  • Excellent finish on the block
  • Bling for your box
  • Good performance
  • High-flow barbs
  • Mounts on popular platforms



  • Poor online documentation / specs
  • Cheap looking hose clamps kill some of the overall finish of the entire product


I can't dock too many points for documentation at this point as the block is not yet available for retail.  The cons listed above may not apply to the finished product, but they do apply to the sample that we are reviewing.


I'd like to thank Enzotech for sending us this block to review.  We look forward to a final sample and plan to use this block for comparison later on.

We'd love to hear your feedback in the forum at the "Comments" link below.
