My current system:
P4 1.6GHz, active cooling with Arctic Cooling Super Silent 4
ATI Radeon 8600Pro, passive cooling with Zalman ZM80C-HP
MB Asus P4S333
2 HD, both in passive Zalman ZM-2HC2 cooler.
PSU - NorthQ NQ-4001, 400W, One 120 mm fan
Temperatures in the system (ambient temperature ~22C) is:
Idle: CPU - 40, MB - 28, HD1 - 46, HD2 - 42
Load: CPU - 45, MB - 33, HD1 - 48, HD2 - 48
My plans are to by the Scythe NCU-1000/2000 passive CPU-cooling and a new fanless PSU (Antec Phantom or Silverstone ST30NF).
Doing this my system will have no fans and the heat may become a problem.
I have done some mesurements on the AC side and have found that the system drains at most 0,[email protected]
=140W. The NQ-4001 have a specified efficiency of [email protected]
to [email protected]
Calculating with 60% this give a heat loss of 56W.
Both PSU:s I'm planning for have an efficency of ~78% wich would give something like 31W of heat instead of 56W I have today.
Are the caluclations correct?
Are the calculations relevant?
Can you draw any conclusions from this?
