In case anyone's interested, I have installed a Northbridge type heat sink, the Enzotech CNB-S1

Please see the album I created for detailed photos:

I applied it on the 3 chips with a double sided self adhesive thermal pad. I chose a 2mm thick thermal pad as I wanted to even the distance from the top plate of the acrylic enclosure.
This means that with 27.6mm height of the heatsink itself and 2mm thickness of the pad, the heat sink sits securely on chips and the top acrylic plate pushes it into place very slightly with a mild pressure. I have put 2 small copper heat sinks to the memory chips underneath the board.
This particular heat sink is not only secure and pleasing in the eye but I get barely 52 C degrees ,running IP webcam as a server while I had been reaching 70 without heat sink. This means a well 15-20 degrees benefit! It might not be cheap but I think it well worths its money I think.
I have since also experimented with installing a small 30mm x 30mm 5v fan blowing air towards the sink from the sides. Running tinycam monitor it doesn't get over 50 degrees! It ranges from 48 (!) to 52 max (very rarely under background mode - recording and server mode) This is truly amazing numbers. Monitoring the CPU-Z app I can see all 4 cores running at top 1152Mhz with the load ranging between 70-95%. I know it's quite high but with temperatures this low I don't think that there's anything to worry about. If I run IP Webcam with this setup I get temperatures in the early 40's or even n the late 30's.
Taking into account that the heat sink is paramount on A64 unless you use your boards for very basic things, the specific one is a great choice. Sure it comes with a price but fits like a glove to the board with only problem being it is quite heavy (over 80g) and I don't know what would happen if anyone tried to use the board in a vertical non-flat position. Probably the thermal pad wouldn't stand the weight of the heat sink. Unfortunately, you can't take advantage of the pins that comes with it to secure it onto the board.
All in all I'm very satisfied. I don't plan using the fan. I just put it it for the shake of experiment. The enzotech alone is perfectly adequate for my needs.
Next challenge is overclocking. I would really love to have been able to do a mild oveclocking (1.34 - 1.5 GHz). It would be really beneficial for my ''DVR'' board which works in high load all the time. These extra few Mhz would make a big difference in my case.
I have ordered good quality cable and hope I can make a usb to 2-pin PST lead to power the board through Euler.
Whoever has a clue or has achieved to overclock the board, I'm all eyes and ears!
