Hi guy´ s
Ivé got a Z4 Water block... i bought it becuase of the fact that i didn´t know any better then.. hehehe...
But i must say that i´m pretty happy with the block and it´s performs is pretty much OK...
it´s about 1 to 2c over å DD water block that a freind of mine has, not that bad...
Ivé used it almost a year now an there is now signs of any batterie effect starting or any ware on the plating inside...
Iv´e used only distilled water and Antifreez and it works great
All inn all i would say it´s a middel of the pack block..
Just one thing i had to do was changed the clamping bolts and nuts because they kept snaping off when they where put togheter a bit tight, LOL
Using steel now with nylon washers and it works great...
-P-
