2 waterblock questions
 

1) Since Little River is no longer accepting orders for Cascades, Dtek seems to be permanently sold out of Whitewaters,and the RBXs are reported to have difficulty contacting the cpu correctly with any kind of side-pressure , what waterblock would you guys recommend I get? I was intending to run a WW/Danner Mag3/86chevette core (or BIX for space considerations) in a Lian-Li pc60. (athlon/A7N8X for now, athlon mobile and NF7-s to go in after I have confidence in watercooling)

2) Since I've read so much about corrosion in systems using copper and aluminum in the same loop, why does the Dtek WW have a copper base, alum top option? Wouldn't this cause the same corrosion?

1) you can buy whitewaters from other places, and RBX's are fine, they come with their own set of pads you place so they contact the block

2) dtek anodizes their alum tops so the metal isnt exposed to the water. even if it was, you can just throw in some corrosion inhibitor (IIRC water wetter acts as one) and it makes sure nothing happens.

Everywhere I've found so far that sells WWs, is sold out of them. Got a link to someone who isn't? In the recent waterblock comparison pHaestus did with the RBX, WW and Cascade, he said he had a lot of trouble getting a consistant mount with the RBX.

if your in the UK, here hasnt sold out, http://store.over-clock.com/D_Tek_Blocks.html

In the U.S., :( can't find a WW anywhere and would really prefer it to an RBX.

i believe this canadian store has them in stock.... but it's pricier than a US outlet i think...
