I tested a RE

The stock heatpipe unit was like TM's no contact at all and could not bend it to make it fit so went to aftermarket cooling 'no big deal'

Problem is when cooling the chipset with cool water below 24c temp via bios reading any voltage over 1.401v including auto and the board will not post

Once I turn off the water and chipset goes over 25c it will post with nb voltage on auto to 1.7v+ no problem and once I post and set voltage/fsb and then turn water pump and get chipset to even 10c with ice water inside windows Im fine untill i have to reboot which then results in a no post

A very weird issue which made me stick with air for now and I dont even use a fan for the thermalright nb cooler as when I bench test in the AM when ac is on and house is cool, as even then the nb can be below 24c and I can't post at over 580mhz fsb,

vcore tho is fine as is all other aspects of the board just a weird x48 issue which Ive seen happen on a p5e64 evo board so I guess this happens to some.
