Well, I changed the direction of the rad fans (now they are exhausting case air over the rad. Temps are:
System: 39'c - 41'c
CPU0: 46'c - 49'c
CPU1: 49'c - 51'c
HDD: 31'c - 34'c
Ambient: 30'c (est.)
So things have cooled off a bit, still not good enough (need at least 15-20'c cooler) So tommorow I will go out and pick up some 120mm Panaflos and see what happens. I am also going to start construction of the chiller this weekend, hopefully I will be able to run some tests by Monday. If all goes well I will install the chiller Monday night or Tuesday and change the flow at the same time. New flow will be:
RAD -> CHILLER -> CPU1 -> CPU0 -> NB -> PUMP -> F&B -> RAD
Above temps are with the system pretty much at idle @ 133mhz FSB. I have noticed that even when I push the FSB to 150 the system still runs stable without raising vcore and the temps go up maybe 1-3'c.
As I am typing this I have been monitoring the temps and the MB temp has been rising fairly steadily. Started at 38'c now it's at 41'c in only 20 minutes. I really need to figure out how to get rid of all the hot air on the MB side of the case!!!
I really don't think another rad s necessary. My HT(max) is around 126W and the 676 should be able to handle that, but I would like some hard data. Another problem is MBM only reads the MB temp sensor on my MB. Since the sensor is located under the CPU and there is very little air flow there my guess is that a pocket of hot air is being created causing the MB to report slightly higher temps. I can install a thermister and correct for this , but right now it's not worth it. I am very sure that the CPUs are hotter than I would like them just by grabbing the rad input and output hoses I can't feel much of a temp difference between them.
