P4C i.e. P4 Northwood core, FSB 800MHz
Those temps are just sitting in the BIOS. When in windows browsing
runnign a few progams, it goes to 53C, it dopesnt reach more than that
for long. One reason why the temp is so high is because an Asus board,
uses qfan, (qfan is a BIOS thing on asus boards that starts raising the
CPU fan speed a little bit when the temp reaches 50).
by ambient temp, do you mean temp in te house or in the case? I
mentioned the case temp. I guess you mean the house. I don't no. It's
The reason the temp is not in the 40s (like my Athlon XPs) is because
the case is cramped. The PSU is proprietary , clips into the case. And
it sits right over the processor. And there's no holes in the PSU over
the processor, and i'm using qfan, my CPU fan is spinning slowly,
otherwise it's too loud.
I could add an exhaust in a PCI slot.
I guess what'd be great is an alternative to qfan. A heatsink with a
fan that adjusts its speed based on the cpu temp.
(maybe it's only qfan2 that has a ratio that controls fan speed to cpu
temp. When I enable qfan i don't get a ratio. So i'd like to disable
qfan and find an alternative.)
I can google around for that alternative though.
And, since intakes aren't so important. I could add an exhaust. There
are single slot pci exhaust fans.
