Howdy PFlo,

question,  what kind of a cleaner would you recomment for cleaning hoses and copper waterblocks in a typical watercooling system.    Mine seem to get  a milky white residue on the hoses even though I use distilled water.

You have mentioned that you're in the process of manufacturing GPU Blocks.  Is there a date in mind taped out, or is it still too early to tell?

Reply to the first question from Howdy Duty by proxy ;)

The "hybrid" design, i.e. AL and CU, was chosen for durability, cost and versatility.  The drawback of creating galvanic action (between two dissimilar metals) is a factor but can be reduced by using a water-wetter or a ethylene or polypropylene glycol mix.  In our test systems winshield washer fluid works great!! Straight windshield washer fluid... yes!

We get the same "clouding effect" on our hoses too.  We have not yet tried to clean these hoses.  My best guess would be to use a mild detergent with a little vinegar.  Then throughly rinse the system before putting the coolant back.  Again, this is my best guess.

Next ;D

The date is near... The geforce 4 model will be out very soon... the first set of prints left my desk last Friday!!  The Radeon and Chipset block will be coming after that.  Those prints are still tied up in engineering >:( :P

In regard to your new radeon blocks.  The radeon 95XX - 98xx have a different core design where the core die is slightly below the level of the shim.  Has PolarFlo done anything special to their blocks to make sure that there is good contact with the die of the GPU?  (taking the shim off is not a good idea because the cores are soo fragile)

Is there any radiators that you recommend to use with PolarFlo waterblocks to provide ultimate cooling?

Yay I made it!

Thanks for the first reply.

I have another question for you.  Maybe I'm being too scientific, but here goes.

Another question relating to differences in metals is expansion.  I'm not sure what you use to seal your blocks but when two metals are clamped together and heated, they will try to expand at different rates.  If the metals are held tight enough it can warp the surface.  If they're loose enough, they will slide on each other, but will eventually deteriorate the seal.  While the block will probably never repetatdly get hot enough to cause this, did you take this into consideration when designing a hybrid block?

Very good... this is what we are working on.  We are trying to make this radeon/chipset block work on a variety of Radeons and Chipsets... but for now we are gearing up for the GF4 gpu water block release...

Reply to Howdy Duty:

Whew!! hang on a minute here.

Okay,  Yes, you are absolutely correct.  BUT there is not really enough thermal effects on our polarflos.  copper expands at about 6-8 millionths per inch per degree,  Alum. expands at roughly 12 millions per inch per degree.  The net effect of these differences would need to be awfully high to wear the seal.  Our sealing method includes a o-ring seat to prevent blowout and creepage

How often do you recommend changing the water in a system?  Providing of course that it remains free of contaminants.  3 months, 6 months, more?

Last question of the night for me.  

In a water cooled system where there is more than one block, like a CPU block and a GPU block, would you recommend plumbing them in series or in parallel?

That's it for me.  I'd like to thank Zeus for arranging this live Q&A and Polarflo for the superb info.
