RADIICAL COMPUTING - SRX Fitting Guide

The Radiical SRX water block was designed for use with Socket “A” motherboards.The fitting mechanism is made up of two stainless steel clips, which act to pull the block down onto the Cpu surface.

This commonly used form of fitting is more sensitive to the parallelism of the block surface so the SRX can be a little more difficult to fit than our other blocks. To reduce this difficulty we have put together a guide for your use. Detailed below is a step-by-step procedure for fitting the Radiical SRX water block.

Step 1

Prepare the block for fitting by assembling the various components in the places they will occupy within the case. Place the pump and radiator where they will finally be placed. Attach the water block loosely to the Socket using the clips provided as illustrated in Figure One. This will give you an opportunity to trial fit your tubing and block without your CPU in place.

Fig One Fitting clips position

Please note that the fitting clips should face in the direction shown like arrows pointing away from the Socket box. A gap of about 1 mm should be left between the SRX water block and the socket box assembly. This is shown more clearly in the picture below.

When the components have been placed in their respective positions layout and measure the tubing to connect the parts together. Allow a little extra on each cut so that minor adjustments can be made to internal placement of the tubing. Keep in mind that you should measure the tubing three times and cut once.

Step 2

Assemble the tubing to the various parts with the tubing clips i.e.; radiator, pump, water block, reservoir or “T” line if you are going to fit these components.

Figure Three illustrates the order of placement of the parts in the cooling loop.

Figure Three

You can see from the stylized drawing above that the flow of water should be from the outlet of the pump to the inlet of the block and from the block outlet to the radiator. The water flow is then taken from the radiator to the inlet of the pump completing the cycle.

Step 3

When you have completed Step 2 remove the components from the case and fill the unit and leak test outside of your case. Fill the unit with demineralised water/corrosion inhibitor in a ten per cent solution (10:1). This can be done by immersing the pump and removing the tube going from the radiator to the pump inlet. (Do not immerse the pump unless it clearly states that it is suitable for submerged operation.) Shake the various components while the cooling loop is filling. Pay particular attention to the radiator. If you have purchased a non submersible pump like the Swiftech 12 volt pumps you will have to fit a “T” line to fill your system, add a reservoir or use one of our three tap kits.

Step 4

Final fitting of the now filled cooling loop can be carried out when you are happy that no leakage is likely. The SRX block should be attached as per Figure One. Note the direction the clips face in. Attach the SRX block clips to the three hooked portions of the socket at each end. Tighten the thumbnuts until slight contact is made with the CPU surface. Verify that the block is sitting flat on the surface of the CPU and is not in contact with the socket box. A gap of approximately 1mm should exist between the block and socket box as per Figure Two.

Tip

My own personal preference after fitting this block many times is to install the bottom clip first then the top clip.

Final tightening should be undertaken with care. It is very easy to crush the CPU core if excessive force is used. After first contact I use a one quarter of a turn of the thumbnuts until I cannot rotate the block by gentle twisting. This level of tightness is sufficient to maintain good contact against the CPU core whilst resisting the pushing action of the tubing on the block.

The development of the Multiplate has increased the adaptability of the Radiical SRX so that is can now be fitted to practically all CPU socket types where manufacturers have stayed within the defined "no go" areas of the motherboard.

The SRX block would have come with a set of screws to attach the Multiplate The package would contain four small screws like those illustrated here.

The Multiplate is fixed by screwing in the four screws as illustrated in the assembled SRX block above.

The SRX would have come with two longer screws which are used in conjunction with the two Multiplate end holes to attach the SRX block to AMD 64 CPU. Further details concerning this can be found in the AMD fitting guide here.

The final package of screws are used for Intel P4 and LGA775 sockets using the four through the motherboard mounting holes.
