Well. There is a good way to install the nvidia driver correctly and the avoid problems later. Here is a great howto, step-by-step, easy-to-use.
But let me correct it out, regarding the 10.04 release !
First of all (before steps), download the "dkms" pack from the bottom of the post on the linked page, and the nvidia driver from nvidia.com into your home directory.
Step1, remove the drivers. Fix the "180" to "190" or "195" , don't sure how Ubuntu calls it at the minutre.
At step 2, edit /etc/blacklist.d/blacklist.conf . Add 2 new entries to the end:
blacklist nv
blacklist nouveau
Then do a reboot, at the boot menu, select recovery mode. Go with the "root mode with networking" (or what, its at the bottom, you will be able to identify it, don't worry about the instructions. :))
When it boots, type your root password. Then type: init 3 . Login again (yay).
Now, install the driver with sudo sh ./NV* . There will be an error about "distributor provided.." don't care about it, just agree, yes yes (more, grep, fsck :)).
After it finishes, do a sudo nvidia-xconfig . THEN, do the sudo sh ./installdkms* part. After it finishes, you are done, reboot.
Yeah I'm aware of the howto and how its 'harder' than the "install restricted modules". However, a lot of people noticed issues , anomalies with the default driver. This way you will get the NVidia binary driver, more recent than the one Ubuntu ships, and it won't be a problem during kernel upgrades. Also, you can upgrade the driver by hand whenever you want. If you get stuck, comment, ask. (Check which part seems to be hard , check if you can find that blacklist and such before you dive in.)
And yeah, after this, we'll continue with the CUDA stuff. :)
The fan is doing it's job by brining down and stabailizing, but the temps seem high. The hard part is that you may not get an accurate read from third party temp monitors.
As this is a custom built rig, there are a few things you should review and wipe off the list of potential culprates (if in fact the temps run this hot):
- Check that the heat sink is attached properly (all corners are down and attached to the board).
- Check for BIOS update. Could be a fan/temp/CPU update for your board.
- Thermal grease - you used not too much and not too little?
- Be sure case is clean and heat sink free of dust.
The cpu may be running hot but it is under load and is not shutting down the system. That is the true sign of overheating and protection will kick in one the thermal limit has been reached.
Intel also has a processor diagnotic tool that could be useful.
Also a reaffiming note from communities.intel.com
Anything from the Tcase and below will be the expected temperature of the processor in normal use, anything that doesn't stress out the processor (watching movies, burning CDs, browsing the internet, creating documents, etc.) When the processor is stressed out meaning that you are running heavy processor applications that take control of the CPU or uses it at 100% the temperature will go beyond the Tcase. It can perfectly reach 90 to 95 degrees and the processor will still be OK. The cooling fan is in charge to keep that temperature there.
If the processor temperature reaches 100°C or more it will send a signal to the motherboard to shut down to prevent mayor damages and most likely it won't be possible to turn the computer back in until it cools down.

you dont need the first two, they are for updating the nvidia software, and i would disable them, or set to manual so they might start if you are using the nvidia control console.
I would disable shadowplay ONLY IF you run verylight-light gpu tasks. if you use any graphic software / games / video / dual screen - keep it.
