CPU fan speed still high after new video card

I built my pc myself with the components you see below.
I started playing Battlefield3 and noticed that my cpu fan would begin revving very high and could see on my G15 keyboard that the game was consuming 60% to 100% of my cpu.
I did some searching and found that most games can only use 1 core of a multiple core cpu. I also learned that newer video cards now use cuda cores to take the load off of the cpu.
So I upgraded to a GTX660Ti video card with 1344 cuda cores.
The change playing the game is enormous. The detail is incredible, so I don't feel I wasted my money.
However, the cpu fan still spins very high. My cae has 3 front fans, 2 rear fans all 120mm and 1 top fan which is 240m; which I turn to mid speed and seems to help.
My questions are:
1. Are there settings I need to change on a component or
2. Buy an aftermarket cpu fan/heatsink and replace the stock unit?
Thanks.

video card EVGA gtx 660ti

If you get a faster card, Your cpu works harder to feed the card faster.

If the old card was GPU bound(this can be seen by low cpu usage and performance that does NOT improve with a faster cpu. Simply put the cpu is working as fast as it can, so the cpu has to wait for it to need more data), then the new card would increase cpu load for sure.

The key is balance. This is why you do not want to have a extreme cpu with a weak card or a strong card with a weak cpu for a gaming system.

The CUDA cores are shaders on the card and used for the games as well as some general purpose computing on programs that can use them for it.

They may take load off the cpu for lets say video encoding(Physx and some game simulations, but in games its mostly for better looking games) with support programs.

What was the old card?

If you are looking at an aftermarket cooler. Check out the Coolermaster 212 evo. Not too loud and performs great for the price.

The first place to look at are your temperatures , If your temperatures stay relatively low when your resource utilization goes very high and there is no change in the noise from high to low then you may find your systems cooling is not set to adaptive mode ( eg is stays on high cooling and noise all the time rather than throttling depening on temperature)

Some graphics cards can actually be noisier than cpu coolers , my partners old gtx 260 sounds like a harrier jump jet taking off when she launches sky-rim the best way to tell would be to take the case screws apart launch BF3 play for an hour or so and then get down under the desk pull of the side and identify where the sound is coming from ( cpu cooler or the Gpu blower on the back)

If it is your cpu cooler would actually look into a closed loop liquid cooling system they have really advanced in the last few years i love mine to pieces it uses liquid rather than a large fan too cool a radiator and disperse heat , as easy to install as an air cooler but much much quieter

If its the GPU .. well theres not a lot you can do there :(

It has gone so far that user Dwood sells brackets to fit most cards and water coolers.

I don't personally liquid cool my cpu, but my heat sink is more then quiet enough(but it sure does take lots of space), But the video card idea looks interesting.

Arctic cooling also makes a all in one VGA cooler, but its a bit on the expensive side for what it is.

download and run cpu z and tell us what your cpu thermals are idle and loaded in the applications/games you are experiencing the problems.

list your CPU cooler also, i'm guessing it's stock boxed intel fan right?

holy crap great idea to ebay ..... I wonder how much i can grab some 2nd hand closed loops for , the sound of the mr's 260 is driving me bonkers right now i cant even hear my rig but i can hear that rear blower a mile off

Probably beyond most first timers experimenting with closed loop liquid though ... especially if they haven't made the leap from stock to after-market

Thanks for all the help, I really appreciate it.
It may be a couple of days before I post the solution, my work scedule is heavy this week. What I am going to do is borrow a infrared thermal thermometer we have here at work also to check temps.

I want to thank nukemaster for the software link. my cpu temp was mid50'c and one ime max'd out to 83degrees! Turning all my case fans lowered it to lower70"s.
I ordered this http:// and should have by Monday.
Thanks again for all the great suggestions and now know where to get the best advice..right here from you guys. thanks again.
