Yes, as Tron correctly predicted, the "coming soon" project was my very first foray in to the murky, dark, depths of watercooling.
I had it all planned for Saturday just gone. I read, and read and read some more on lots of not very friendly forums (the world of PC watercooling is filled with very snobby people!), and I eventually ordered the following kit:
Zalman Reserator XT - This is an all-in-one external single box solution. See, it turns out to watercool a PC, you need a reservoir (for the water), a radiator (or rad), and a pump to circulate everything. You also need lots of room to shove all that in your PC. The Reserator XT is an external box (about as big as the good old mini-towers we all loved/hated back in the 90s!) that contains all 3 elements.
The kit also includes a CPU waterblock, and I purchased a NorthBridge one. My NorthBridge runs at 50-60 degrees (nothing dramatic, within normal), because I've overclocked the CPU to 4.2ghz by increasing the BCLK to 200 and multiplying that by 21.
EK HD5870 Waterblocks: These are used to cool the VGAs. Installing them involves disassembling the factory fan/heatsinks, and replacing them with the blocks. It's scary!
But, I couldn't carry on doing anything on Saturday! See, in my ignorance, I failed to order some VERY basic couplings which didn't come as standard with my VGA blocks, hence I had to delay everything. I placed another order for everything (I hope!) and that should arrive tomorrow!
SO - why all this? See, my HD5870s are both 2 slot cards. When sat together in the motherboard, their fans have virtually no room for airflow. This leads to the cards getting stupidly hot when active (90 degrees), which in turn makes the fans loud. More importantly, when the cards reach these temperatures they throttle their performance, leading to a palpable dip in performance.
Keep your eyes fixed on the blog tomorrow, hopefully I'll manage to get everything installed, and most importantly, NOT LEAKING!
