Assembly instructions for Athlon 64/FX: The official way

The rear cover:
1. Mount the heating element in the rear cover.
2. Place one line of seal string at the edge of the rear cover.
3. Insert screws in the 2 holes of the cover.

Position of the rear cover:
Make sure the rear cover has the correct position on the motherboard! The straight line edge of the rear cover should be placed towards the edge of the motherboard running in parallel. Confirm that the screws have placed through the mounting holes.

Cpu: Insert the CPU in the socket.

Prepare the mounting bracket:
1. Metal clip is pre-installed but should be checked for correct installation.
2. Place two layers of seal string around the edges of the mounting bracket.

Connecting cover and bracket:
Align the cover screws to fit the mounting bracket holes and tighten the screws until the kit has firm grip. Not to over tighten the screws! (If you do, the bracket will bend slightly!) Again check the mounting bracket for his correct position on the motherboard and CPU! The metal clip should not cover the CPU to much! The straight line edge of the bracket should be placed towards the edges of the motherboard running in parallel.

Sealing off the screws:
Always remember to seal off the 2 screws on the mounting bracket with a bit of seal string to prevent any gab! Causing air entering the hermetic sealed chamber (when correct mounted)

Applying the micro freezer:
Place one layer seal string around the edge of the micro freezer. Apply thermal compound onto the CPU. Place the micro freezer onto the metal clip and tighten the 2 screws and turn them until you feel that they are in the bottom of the threaded brass stands. It is a good idea to tighten them almost simultaneously. Finally place some seal string on the tops of the 2 screws, to seal them off entirely.

Assembly instructions for Athlon 64/FX: the [M] way

We are not called MADshrimps for nothing. Our installation guide is for those readers who changes CPU more often.

For a practical example, let’s mount the S775 kit on a motherboard; in the pictures below you see the kit without seal string or CPU, but as you might have figured, those are needed to finish the complete installation.

The installation is really as there you only need to tighten 4 screws (2 for AMD S754/939/940). You then place the motherboard with the CPU kit in a case. We have used the ECT uppercase but as there is a nice aluminum parts kit for the cooling unit you can use a flashy aluminum case instead.

Now we mount the evaporator head on the CPU kit, remember to be careful again with the hose. This is delicate piece of the unit! Fitting the head is done by screwing tight 2 screws; make sure not to overturn them, afterwards cover the tops with seal string to prevent condensation.

This far we have followed the official installation instructions; it’s time to show you the [M] way. If you change your CPU often and you don’t want to peal off the seal string every time a work-a-round has to be found. Instead of the seal string I use a thin layer of foam. I don’t want to take al the credits for this, first time I saw this was during a visit at Epox Europe. Mister AP.Versteeg was using this method because he was changing motherboard and CPU’s as often as me. So the credits for this installation “trick” go to him for sure! Do remember though that this is not for 24/7 use

Now here’s my input, instead of screwing the 2 screws from the rear cover in the bracket, I found a new way. As an A64 kit is always used on 754/939 or 940 socket the motherboard holes are always in the same location (this applies to S775 and S478 as well).
Why not make a more permanent solution? Like fitting the bracket sealed tight to the micro freezer head.

Pictures can say more than words, so here’s the Mach II with P4 kit installed:




How does this work when mounted in an operational system? In the photo’s below you see an Athlon 4000+ all ready to go. Changing the CPU only takes like 2 minutes now, because the hole in my back plate is cut very rough I need to be careful with the sharp edges. Next on my TO DO list is using a dremel to remove those



Using one PSU for powering the Mach GT we can test the unit without using the motherboard and the other hardware.


Time 2 hit the switch

What can this baby do? The GT display sensor is mounted on the outlet, so we placed a k-sensor on the evaporator head. This is done on the side because we want to keep making good contact with the CPU.

At startup the display reads 17°C, it takes roughly 40 seconds to reach 0°C and after 2 minutes the unit is running cold enough to boot the system. Just for kicks I let it running without load and the display went all the way to -71°C, quite impressive! The evaporator heads is at -55°C at this point.
