Swiftech XT
 

Am I the only one having problems with this block? Lives up to it's rep in reducing core temps by up to 10C against the GTZ, but it's so restrictive it sometimes causes issue for me. I do have it on a rather large loop though :blush:

I got it an it sux compared to the gtz on my chiller. realy restrictive imop

heres a pic for those who never seen the inside

Maybe a higher preforming 120v pump would fit the bill here

this one will do 2100 GPH give or take roughly 4 to 5 time the capacity of the 655

just make sure your SS clamps are tight and trow away any of that plastic or titen ties stuff ...................LOL

ive had 2 inline pumps no differance in full load temps.

Mine is working well, water does flow a bit slower, but hasnt been backed up or anything. What coolant/mixture are you using? I mixed two bottles of Pentosin G11 and two drops of PT nuke with distilled water. Res -> pump -> rad -> rad -> XT -> vreg block -> res.
