Swiftech MCW6500-T TEC (Peltier) Assisted Water Block

Installation:

The previous extra gasket I made was a bit too thick and didn't really let the retention bracket sit on it properly. So I made a new one with cut-outs for the protruding "feet" of the retention bracket.







This allowed the retention bracket to fit a lot better and gave a firm seal all the way around underneath the edge of the bracket.


There was only one supplied 939 socket gasket, which didn't really seem to come up high enough to make a seal with the TEC-block's own neoprene. There actually appeared to be a gap of 1-2mm in some places between the MCW6500-T's neoprene and the gasket. So I made a further inner gasket. You can see that the CPU sits below this gasket now so the neoprene will definitely be sealed all around.

 


Rather than cover the CPU all around with a thick, even layer of grease, I sealed the surrounding air gaps around the socket, covered the surface-mounted capacitor networks on the CPU PCB, and tapered the grease off towards the CPU die so that the grease wouldn't end up between the CPU die and the MCW6500-T.


So, putting the inner gasket back, the retention bracket, and bolting the TEC-block with the supplied screws and springs through to the backplate, I finally mounted the MCW6500-T to a working CPU socket.

 


Now, the lead for the MCW6500-T is terminated with a 4-pin Molex connector, to allow you to use it with a high power ATX PSU. As the lead is only short and I needed to make a short extension, I decided to use Tamiya and Kyosho connectors instead of 4-pin Molex. These connectors are widely used on radio-controlled car battery packs, motorbikes, cars, etc. They can handle a lot of current and have a locking clip which is a lot less annoying than awkward 4-pin Molex connectors.


So, I made the short extension cable to connect to the Meanwell PSU. I then re-terminated the MCW6500-T with a Kyosho connector.


Now it's just a case of hooking up the two locking connectors.


The wires on the lead from the TEC do get quite warm, verging on calling it hot. You don't want these to rest up against the tubing for your water, else it may melt a hole through it, or deform it causing a kink, or other nasty surprises. Actually, the whole Meanwell PSU gets pretty warm, like about as hot as a mug of coffee that's been sitting there a few minutes - not too hot that you can't touch it, but very warm. When the Meanwell PSU's fan spins up, the air coming out is also very warm. It's a 60mm high performance fan, so when it spins up, you know it's spinning. It wasn't annoying to me because it was mostly drowned out by the other fans in my system, but it could easily be annoying if you have a near-silent computer.

Below, you can now see why I can't position the Meanwell in the upper bays. The massive black thing below the blue radiator is a fibreglass air duct that makes the radiator take air in from the side, outside of the case, rather than the warm interior case air.


Hooking everything back up and firing up the rig, going straight to the BIOS thermal monitoring section brought a smile to my face! Only 6°C. Finally, the hardware installation was over.


These initial checks to make sure the installation had been a success certainly bode well for the testing that was to commence.
