what would be the reason for watercooling?
Exactly, sometimes watercooling has no practicality or advantage over high end aircooling but if you have the money and the time then why not make your rig look unique and a sexy beast at the same time?
I know i've been doing it for just over a year now and i dont think i'll ever stop lol. Even considered making some of my own waterblocks if i can find the right company to do it for me!
I bought http://www.overclockers.co.uk/showproduct.php?prodid=GX-174-MS the other day as well as the Antec A280, and it's extremely quiet, I also have that first CPU cooler that Jamsames mentioned
My CPU & Case fans can be heard over this baby!!!!
So so Quiet!
If you're wanting to splash a bit for your cooler, I can fully recommend the Alpenfohn k2 doom. Got it for £47 on a deal and it's fantastic, excellent with the PWM fans also. Very quiet, very cool, looks awesome!
