Default Re: i7 Core WC setup - Unacceptable temps

Reporting changes noticed:

I went ahead and found a spare older fan I used in my current WC setup and swapped it with one of the Noctua fans on the radiator. Currently running both fans at full speed, the water temps dropped 3-4C and the CPU load dropped about 4-5C which was expected but that just means that the CPU is now running at 77C instead of slightly over 80C.

The temp prob in the res. is registering around 32-35C depending on ambient and which fan combo I am running. The CPU temps are ~40C idle and 75+C under full burn mode. At this point, I am probably going to swap out the current pump (Swiftech MCP355) and try the Ehiem 1250 in the system to see if that makes a difference. If that gives me significant gains (10+ drop in temps maybe) then I will probably convert the whole setup from 3/8 to 1/2 and go with the Swiftech MCP655.

The difference in tubing and pump will make an already cramped enclosure that much more cramped but guess I underestimated the termal output of the i7 920 would be.

More to come as I continue experimenting.
