I have an arctic cooler on this, its too hot (cpu),
How hot is too hot?
What sort of cooling system can i get without breaking the bank.. ie:
We don't know the reserves of your bank. Expensive to one person is
cheap to another.
I'm thinking i'd want some sort of software notification of low
levels, external access, cooling of cpu and north bridge, but maybe
this is too costly and i can cut the notification and external part,
though some, like with the swiftech, said they couldnt fit an internal
system in their case.
Depends on the size of the "room". In the room where you use your
computer, what effect would 4 100W light bulbs have on the temperature
in that room? I doubt you are actually consuming 850W. Get an ammeter
to check current draw by your host to figure out the real power
consumption (and during continual use after all devices are powered, not
during startup).
If a device is generating N therms, it will still produce the same N
therms regardless of what cooling you use to remove the heat (the better
cooling is to help remove the heat faster from the device). So it will
still get the same heat dumped into your environment. If you want it
cooler in your office, do the same thing a faster fan on the CPU would
do: cycle the air faster through your office. That means leaving the
fan to manual rather than temperature regulated (providing you get a
separate fan and control), or leave your door open and put a fan that
blows out but aimed at the top of the door opening or moves the hotter
ceiling air towards the door.
Stop thinking temperature. Start thinking heat. If you dump the heat
faster into your office, the air circulating back into the computer is
hotter. Cooling works due to differentials in heat. What good will it
do to be able to cool a device faster if it merely ends up pre-heating
the air used to cool it thereafter? Fix your heat issue in your office
first. If you need to use an enclosed space in which you have no
control over the airflow through it then you'd better check out just
where you can router the tubes and position the radiator so it is
outside your office.
46C (114F) is not that high for case temperature. I use Speedfan to
reduce fan speed (and noise) until case temp goes above 40C and warn if
it gets over 50C. I use it to reduce CPU fan speed (and noise) until my
old Athlon XP gets up to 55C and warn at 65C (with the BIOS configured
to shutdown at 75C). Go to Intel to get the *operating* specs for your
CPU. The device is still supposed to work within that operating range
of temperatures (provided you haven't modified anything, like
overclocking). If the operating range for a CPU is up to 80C and
someone says they get flaky operation at 65C and why they are
desparately trying to lower temperatures then they've told you their CPU
is defective and they didn't bother to get it warranty replaced. For
the x7 9650, I think the max operating temperature is 70C. That is its
*operating* range for continuous use.
You're probably the biggest contributor to heat in your office. The
typical human body produces 100W at basal metabolic rate up to 900W
during a 30-second cycle sprint. Do you tell visitors that they must
stand outside your office when visiting you?
I did some more temperature checking, the ambient right next to my pc
is 81F, down where i sit its more like 77.. when i said 114F, this is
just behind each 4870's exhaust, on the outside of the pc case at the
bottom.. thats probably the biggest contributer to the "heat"..
I'm still thinking the twin fan setup may help.. short of ducting the
heat to the fan.. and short of going water cooling with the radiator/
resev. somewhere else.. not even sure where else i could route it.
I always keep the office door open, but it can only open half way due
to the odd configuration of furnature.
