Default 8800GT cards too thick!?

I've got a couple of ASUS 8800GT PCIe 512Mb graphics cards on my Asus
P5N-D motherboard. However I didn't realize that they were too thick
to be SLI-ed together! I could insert them alright, but there is only
about 0.5cm distance between the fan of the card on top and the back
of the card at the bottom. I think the heat is going to be a
problem...

Am I the only one who's having this problem?

Should not be an issue with adequate case ventilation. It's not like the two
fans are facing each other. These two will vey likely cool better and be
quieter than the usual narrow shrouded dustbuster 8800GT like I have. That
was the whole point of the newer fan design.

The top card may run 5-6 deg hotter than the bottom card, but it shouldn't
cause stability problems. 0.5 cm is actually pretty good spacing for
dual-card setups. With two HD2900XT cards, the spacing could be near zero
(note the case fan the reviewer jerry-rigged at the rear):

In the unlikely event the top card overheats, buy an aftermarket cooler like
the Thermalright HR-03, which pipes the radiator fins around to the back of
the card.

Thanks guys

My case is a Thermaltake Xaser VI. It still has a lot of space in it
after i installed all the parts. I'll get a temperature monitor
(speaking of which, any suggestions on which ones I should use?) to
keep an eye on them. If it really is a problem I'll try to hook up a
fan.

Rivatuner (software) can monitor the temperature of the card, at least in
the single card 8800gts configuration i am using.

This is actually quite normal in many SLI systems even with large
9800GTX's and such with the double decker coolers. I doubt it's the
most optimal situation for the reference HSF, but it is surprisingly
efficient compared to aftermarket coolers usually. You shouldn't have
to worry about later revision 8800GT's too much, only the first
production series of 8800GT's had poor coolers.
Later ones are greatly
improved in most brands (eVGA, XFX, etc).


Untrue if you mean the physical cooler elements... fan, heatsink
etc...

The BIOS was updated on the later-rev boards from eVGA and BFG (dunno
about XFX) to lower the temperature at which the fan starts ramping up
its speed. ( It was originally stuck at only 29% until the GPU core
temp exceeded 90 degreesC !!) For eVGA, the updated BIOSes for all
the early-release eVGA 8800GTs are available for download on the eVGA
website in the "driver" section. I have an early-release eVGA 8800GT
(w/ 675MHz factory overclock) and the improved cooling after the BIOS
update lowered its max. core GPU temp from ~ 95degreesC to ~
78degreesC in my rig with barely-noticeable increase in fan noise.
