GF3 running hot
 

Hi,
I have a 2nd hand ASUS GF3 V8200 Ti500 Deluxe and it seemed
to be running a bit hot and the fan was running at about 4000rpm.
I've just fitted a Vantec Iceberq 4 (CCB-A4C) fan which runs at 6000rpm.
My CPU and M/bd run cool, here are my gfx card temps:

Room = 25C GPU = 61C Mem = 39C
Room = 30C GPU = 67C Mem = 45C

My PC case is off and I have a 75mm fan blowing directly onto the card.

I'm not overclocking but my mid-tower case is fairly packed with a total of
8 drives and only one PCI slot free. (XP Pro)

And why on Earth do they make these cards upside down?
Heat rises and everything is mounted on the bottom.

LOL! Thats the best question ive seen in a while!!
All AGP cards are populated in that orientation, so that when installed in a
tower case, the heatsink will be hanging off the bottom of the silicon. I
suppose its historical, and for them to change it would cause far too much
incompatibility.
Seems to me that a desktop case is really superior anyway, heat rises away
from all components, heavy heatsinks on the CPU are sitting flat, not to
mention that the case itself can be used as a printer or monitor stand.
Maybe its time the pizza box made a comeback!!

I absolutely hated desktops, they are absolutley horid to work in and the
old ones had very limited space for upgrads.

The desktop is dead, long live the desktop, now lets move on.

It's late, so I guess that's reason enough to correct this misinformation.
Let's set this straight. Heat doesn't rise. That's right, it doesn't. Never
has, never will.

Heat, which is infrared radiation, "radiates", which means it goes out in
all directions at once.

Then you have conduction of heat, which transfers based on the medium
*without* the bulk movement of the medium itself, up down, sideways,
irrelevant. This can be, and is, a useful process, by warming a larger mass
to a lower temp than a smaller one.

Then you have convection, which is where eveyrone gets confused, since the
act of radiation aided by conduction typically sets up a covection current
of air which the *colder* air being more dense is then unable to be
supported by the less dense warmer air and this colder air sinks, and the
warmer air settles on top.

This is why people think heat rises, since they feel warm air convect up.
Sure, you might get all ****y and just think it's semantics. It's not, it's
science, it's thermodynamics, it's big business, and if you were a computer
engineer or a heat sink or chip designer and you said "heat rises" you'ld be
out of a job. :)

To cool your PC, you need to set up the resultant convective current so that
the most dense (cooler) air can either be sucked into or lowered into your
PC while the least dense (warmer air) can be vented out.

Nothing can be done about the infrared radiation nor the conduction, but
minimize their impact by extra convection.

Seems that computers in their current derivation come in a tall slim
package. Who knows what shape computers will be in a few years

This is because ISA graphics cards were originally made with components
facing on the other side of the card. Thus, by mirroring the card, Intel
(who's the guys who invented PCI) made it so manufacturers could put an ISA
and a PCI slot side by side and have both using the same metal bracket at
the back of the computer (not simultaneously, naturally). These days, ISA
slots are long gone, dead and buried. PCI cards still face the same way -
obviously - to remain mechanically compatible with older hardware.

AGP cards face the way they do because the space BEHIND the card isn't
specified to include headroom for components. Stuff sticking up on the back
side might interfere with anything from heatsinks to power connectors to
DIMM sockets or anything else, which it actually does as some people have
discovered when they install large non-standard heatsinks on their graphics
cards...

Not that it matters much, convection only works in large-volume spaces of
UNDISTURBED air. Inside a PC you have at least two fans - on the CPU and in
PSU usually - which disturbs the natural movement of air, and there might be
more too. Convection won't be a great factor in heat transfer wether cards
face one way OR the other under such conditions... ;)

I didn't ask the question to get involved in semantics but since you raised
the issue.
There is no such thing as "sucked" in reference to the movement of air
associated with temperature. A drop in pressure occurs, causing movement
from a high pressure area to a low pressure area.

I just want a cooler running GPU.
