Disable one GPU - asking the impossible?


Well, here is the deal. I have an nv 250 but its fan spins at 100% all the time. Unfortunately, it keeps doing so even when the card is downclocked to less than half its speed. I'm sure you can imagine that having that helicopter sitting next to my desk is not exactly ideal when I'm doing just some text editing. So now I'm considering putting in a second GPU so I can pick the quieter one when I'm not doing anything that is graphics intensive.
The question then is: is it possible at all to have one GPU disabled? If the helicopter is still going to sit there spinning and eating electricity, installing a second card won't be much of an improvement. I don't mind rebooting to select a different card, I just want to avoid the awkward situation where I physically need to switch cards each time.

Have you tried nvclock, you may be able to slow the fan down.

Yes. I get "Unknown video card". It looks like the card is way too new for nvclock; it offers even fewer options than the tools provided by nvidia.

Did you try the lowlevel backend ?

Code:
nvclock -b lowlevel -F 10
Also, I've never heard of an nv 250, what is the full name of the card ?

A good reason to always provide a link to what you're talking about.

OK, it is EN 250 rather than NV 250:

I have fetched the latest nvlcock from CVS and it says that setting fan speed is not supported for my card. I have read this previously happened with the 8800 series, too, before it was supported.

It looks like a relatively new card, are you sure you can't enable coolbits and turn the fan down ?

I have now received replies from a number of GPU related board. It would appear that this card is simply a rip-off. The 250 is supposed to be an enhanced reiteration of the 9800GTX+ but apparently, ASUS has decided to keep it simple and overclock their stock 9800GTX+ ; for some (stupid) reason they also decided it would be beneficial to fix the fan speed at 100%. Other than getting a replacement, there does not appear to be any solution to this problem.

Hmm, I see. That's too bad. I have two re-branded gigabyte ones and they seem to work fine.
