- System Temperature - Too hot - what to do ?

(True to my habit I come here when I face a PC problem. Thanks for
always helping out! I enjoy computing but I am not as knowledgeable as
I wish I was! )
RIght now I am unsure about how to handle a problem to do with potential
overheating of my system..
I have a 3 year old Shuttle of the following spec:
CPU: Intel 2.4 Ghz
RAM: 1GB (2x512)
I have attached an external drive to get more space for multimedia files.
I keep the Shuttle in a smallish cupboard.
Yesterday I finally got around to installing a new graphics card that I
bought 'on impulse' a few months back.
It is a BFG GeForce 7800 GS - supposedly the best AGP card on the market
Previously I had a NVIDIA GeForce FX 5200 card.
(I am not sure that this upgrade was the best use of my money, but I
thought at the time that I needed it since I had no less than 3 large
monitors in use. I don't do gaming though, just browsing, working in
office apps, watching multimedia etc)
A few hours after successuflly installing the card, I noticed that the
poor Shuttle was burning up! It was really too hot. It was hot in the
cupboard where I keep it. Since I am not into overclocking I don't know
any more than the average person about computer temperature
requirements. I got worried and shut down the machine.
I have now installed a tool called CPUCool. It lists temperatures as
"Temp1" (CPU?) = 66 C
"Temp 2" and "Temp 3"= 61 and "Temp Sense 1" = 59 C (I think that
is a the hard drive temperature...... )
I am not sure what to make of these temperatures. I understand that 70 C
is the maximum recommended CPU temperature and I am uncomfortably close
to this after after working for only 1 hour.
The PC was definitely not this hot before I installed the new graphics
card. It was certainly warm-ish but not hot like now.
I am considering swapping back to the original graphics card, the FX
5200. But it seems a shame to have this high-end card and not use it.,,,
Would that be the right thing to do in your opinion?
I also think that the fan on the new card is a bit noisy and am looking
into options for solving this problem and making my PC much quiter. Any
Re: System Temperature - Too hot - what to do ?
Um, you put a high end video card, inside a small box, inside
a cupboard, and then you cannot understand why it is hot :-)
Remove the 7800GS and put the FX5200 back. And don't forget to
uninstall the drivers, before changing the video card.
(while the cards are both Nvidia, installing new drivers gives
an opportunity for the installer to "do the right things" for the
new GPU). Uninstalling the old drivers, cleans up the mess
before the new ones are installed.
There have been some Shuttle boxes, that have a large
meshed grill area on the side near the AGP card. Having
lots of room for airflow, would be key to keeping your
Shuttle box cool. In the pictures I can find of your
Shuttle, there isn't a lot of vent space on the sides
of the PC.
Actually, I'm surprised the power supply did not shut down
from the load. I believe Shuttle offers higher power
supplies, as an upgrade option for owners who use
high power video cards.
So, to start, think like a cooling engineer. Get the box out
of the cupboard. The best cooling solutions use large,
low RPM fans, large area vents, and non-resrictive grills
where the fans exhaust their air. A large tower, as an
enclosure, gives you more room for fans, and you can use
fan speed reducers to keep the noise to a dull roar.
If you want to keep the Shuttle's small form factor,
then consider using lower power components inside your
PC (like the FX5200). The FX5200 is still capable of playing
games, and the BF2 demo runs just fine on my FX5200 :-)
Also, another thing to consider, is your processor is
2.4GHz. Generally speaking, if you upgrade a video card,
you are best advised to proportionally increase the
processor speed as well. Otherwise, most of the potential
of the new video card will be wasted (CPU limited).
And if you are building a "rocket ship", a larger computer
case makes engineering the cooling a lot easier. If you
want sensitive components, like the hard drive, to last
more than a few weeks, then keep the temps down.
