koolance AMD CPU waterblocks

[beasty6]

hey guys,

going to be buying a custom loop for my FX chip and "maybe" my 7990 as well depending on what nvidia offer with maxwell.

anyway, i want to go with koolance waterblocks just because i think they look nice, but is there any performance or reliability differences in these two CPU waterblocks?

CPU-380A

i prefer the CPU-370SA as its black and i like black waterblocks, so whats the difference?

thanks

The 380 supposedly outperforms all the other blocks. (Stren's waterblock roundup) I've got a 380A on my phenom ii and its done a good job keeping it cool. When I dismantled the block last month to clean out the debris it was still like new inside and it is extremely well made. I've been pleased enough with it, that I've just bought the 380i to cool a 4820k which is replacing the phenom.

i think im going to go with EK waterblocks as they have a much bigger selection and can then match blocks in the system
