If it's not too late I have a warning for you - don't buy the new rev of the asus card -it's just crap!

I got my on friday...
...and ok - it has a quiet cooler - not the quietest i've ever heard, but it's ok. And i'm sure it's cooler than the reference one, but i can't even tell if it really is because the thermal sensor isn't doing his job;/ Rivatuner shows 0°C, everest, speedfan and even the asus smartdoctor(or something like that) aren't showing anything. No fanspeed control in riva tuner as well. Searched the web to see if it is only my problem, and it turns out that many(if not every) asus en8800gt with the new cooling has this problem.
Just take a look:

I hope that those problems are only temporary(maybe it's only a bios or driver problem), but right now i wouldnt buy that card for the second time.
