High EVGA 670 FTW SLI temperatures under load

I began playing Bioshock: Infinite the other day and on the second day of playing I experienced a BSOD after an in game freeze. Looking at the minidump, it blamed the BSOD on nvlddmkm.sys, or basically something related to nvidia.

I already had the latest drivers but I did a driver sweep and reinstalled. I have not experienced the BSOD again but this made me curious and I began monitoring temps while playing.

While under very little load (web browsing etc), or idle, both GPU's sit in the low 30's, mid to high 20's (C). I know these are great temps.

When under load in Bioshock: Infinite on Ultra with FPS limiting disabled, or a GPU benchmark such as Unigine 4, my temps spike up to the low 80's C. These seem high compared to most reports and worry me- I've seen it go up to 84C, and think overheating might have been the cause of the earlier issues. Fan's max out at 60% and are on auto. Most people are saying they average around 70C under full load in BF3, though I do not have BF3 to test.

It is probably important to note that while the games are played on one monitor, I am running dual 1920x1080 monitors. Normally a web browser is open on the non-gaming monitor.

My rig is built well with very little obstruction and proper airflow, including aftermarket top fans and a removed lower HDD bay for more open space. I'm not sure what's going on.

Specs:
Corsair 500r
i5 3570k @ 4.5GHz
Noctua NH-D14
2x EVGA Geforce GTX 670 FTW SLI
Asrock Extreme6 MB
16GB (4x4) GSkill RAM
Corsair HX750 PSU
Crucial m4 256GB
WD Caviar Black 1TB HDD
ASUS DVD/CD

Thanks for any help you can give!

Before I go about this I just have a question: are you saying you think both my GPU's are bad? although normally only one has temps in the 80s, the other is still high 70's (78, 79). Also what exactly might be bad with the GPU? It seems to function and idle just fine.

Thanks for the reply!

Still... use only first one with furmark to check temps... I think it will drop quite a bit.

Or open your case and see will be a drop. If so, you have bad airflow.

Your case may be to small for SLI and probably second one gets higher temps because hot air goes to PSU and some reflects back.

Well I feel a bit silly... I just turned on the fan curve in Precision X and now both my cards stick at around 60-64C while under full load. This is with about 60% constant fan speed, as adjusted by the curve. Why is that not enabled by default? My fans were apparently running awfully slowly before.

Will this cause any adverse effects? Such as a shorter card life before the fan dies?
