zzzz kinda stuck... can the 320 handle a 3.8-4ghz q6600 + two oced 9800gtx's ???
sure, if you don't mind loud fans and not very good temps. check out the link ira-k posted, that would be similar to OC'd quad core and 8800gtx sli. Maybe about a 530W heat load since the 9800gtx vs. 8800 gtx based on power consumption numbers (ram heat should be about the same, so I assume the ~15W more is output from the core). or assume the same load for OC'd 9800gtx, also simpler
The number to look at is either yate loon 1550 RPM(high speed yates at a reasonable noise level): 12C over ambient, or Scythe 2000rpm (not too far from high speed Yate's) 9.2C over ambient.
***better with shrouds and/or in push/pull***
could one 480 handle that???
compare that for the 480gtx
numbers Martin has been kind enough to provide for us (Thanks Martin!!):
9.5C/ 6.2C over ambient.
could two 320s handle that???
thats where things get a little trickier as I am not aware of a similar chart for 2 320's. remember that changing parts changes the resistance of the loop and therefore the flow rate. Flow affects cooling capacity of the cpu/gpu blocks, but also very much the rads as you can see from martins testing.
Luckily the estimated change in flow rate isn't very great going from 1rad-->2rads, so a straight doubling in heat removal capacity isn't TOO bad of an approximation
this leaves us in the 6.4C/4.8C region which is quite reasonable. Taking a look at the cpu/gpu blocks cooling capacity over @ swiftnets.com leads me to conclude that their respective cooling capacities will not be adversely affected by the flow decrease either.
Lastly I want to point out that these are the water temp that the rad(s) will maintain, and the temp the first block following them should see. If you have 1 radiator and 3 blocks, the third block is going to have mighty hot water. Even if 1 radiator can handle the load, having 2 spaced out through your loop will keep your temps better all around.
To summarize, my 320rad followed by upgrade to 2x 320 rad if adding a gpu's.
PS. the 360 will offer performance very similar to the PA120.3, listed in the 480GTX link.Edited by SergeRY - 7/8/08 at 9:45pm
