Senfu Watercooler Unit

Installation

Senfu's water block comes in a box with many accessories. Included are clips and screws that  allow mounting on almost any current CPU - Socket-type (K6, Celeron PPGA), SECC2 (P3 and newer P2), SEPP (Celeron Slot 1) and SECC1 (Athlon, old P2). For mounting on slot-type CPUs, an additional metal plate is included. The following picture shows the Senfu watercooler mounted on an Athlon thermal transfer plate:
 

On SECC2 and SEPP CPUs, the water block is installed using screws. This installation method is very high-quality; the pressure between CPU and watercooler is high, and it is easy to add a Peltier element to the system (you will need an additional copper plate for SECC2 CPUs, since the CPU die is much smaller than most Peltier elements).

On socket or SECC1 CPUs, clips should be used. However, the clips for Athlon are not very good; they don't press the watercooler very firmly against the CPU. Putting  a thick piece of cardboard between the metal plate and the water block solves this problem, but this is still not a perfect solution.  Also, with the Athlon mounting clips, you cannot install a Peltier element between CPU and watercooler. The mounting system for Athlon CPU definitely could be improved.

It is not possible to install the watercooler directly on the CPU die of an "opened" Athlon, unless you use thermoconductive epoxy to glue it on the CPU.

The compactness of the heat exchanger makes it suitable for hardcore overclockers who plan to watercool their graphics chip. Installed on a GeForce card (or any other video card), it won't even block the PCI slot right next to the graphics card! However, you'll need thermoconductive epoxy to install it on the graphics chip.
