I have this damn weird problem.... When i am happily playing temps are okay and stuff. I stop playing, i go to the world of internet. All the sudden my powersupply fan goes to higher than the maximum speed (not really) but it goes from standard to max... after few seconds it comes to normal agai.... what seems to be my problem? I stated after i updated my computer...
PSU fan speed goes to MEGA high....

Are you sure that it is the PSU fan and not another fan in the system? Antec tends to make pretty good products, and 750W is way overkill for your system.
Also, use a program like HwMonitor to see what your CPU and GPU temps look like during and after game: http://www.cpuid.com/softwares/hwmonitor.html

hmm cpu is at 37c gfx is at 50c hard drives are at 29c its not showing psu tho... but all the fans are at normal speed... atm.... remember this happened after i updated windows 7. you know when it shows the shield thingy on the shut down button.. it was just a normal update... and after it this happened....

The reason I ask is because the PSU fan is only controlled by the heat sensor onboard. There is no way for Windows, or anyother piece of hardware or software to control the fan on the PSU. If the PSU fan is spinning up, then it means that the PSU is overheating, or otherwise having major problems and should probably be replaced. The thing is that PSU fans (especially Antec and other decent PSU companies) don't tend to have these types of failures.
On the other hand, it could be that when exiting the game then your HDDs are spinning up which can sound like a fan. Or it could be that the CPU is getting a heavy load while unloading and reloading programs which could cause the CPU fan to spike. Or maybe you have some odd feature on the motherboard that forces the temps down quickly after the system is no longer under load (accidentally did that to my wife's PC using speedfan once lol). At any rate, while these are still issues, they would be minor ones. But if your PSU really is having fan spikes then it means that your PSU is having issues... and PSU issues can quickly escalate to destroying other hardware if not dealt with.
So here is what you should do:
1) Let your computer idle for a few minutes while using HwMonitor so that you can get a true baseline of what your idle temperature is.
2) Take the side off of your case and run a benchmark like prime95 or intel burn test, or something that is going to put your system under a long consistant load.
3) Get near your case and find out exactly what fans or devices are making the noise. Use your hand to feel for airflow next to the fans... just don't touch anything.
4) If that does not work, then open up GO and close it and try and find the problem child while the fan spins up.
All that I do know is that win7 does not control fans. The motherboard controls fans, the GPU controls it's fans, a fan controller can control fans, and there are some aftermarket software that can override motherboard and GPU settings. But windows does not control fans, so the windows update (unless you are installing optional MS drivers for things... which you should not do) cannot affect your fan behavior.

Hmm i just blew all the dust out from the psu and from other components. I can tell you this opened fast after it! And no signs of the fan speed thingy. There was alot dust in the psu... i might have to blow the dust someother day more firmly but i am trying some games now

and it is quieter too

there we go! Glad it ended up being a simple fix!
A few tips about dust prevention:
1) store the computer at least 6" off the ground. Even setting it up on a shoe box will get it high enough to keep it from pulling dust off of the floor where dust settles and collects.
2) fresh air is the enemy! keep all windows in your house closed, and run your house fan regularly to filter the air... and make sure that you replace 1" thick house fan filters monthly, or thicker filters every 2-3 months.
3) Animals will fill up your computer in no time. Kill them all! j/k, I have several animals myself... they are a problem, but not quite worth getting rid of.
4) If there is no good way to keep the dust out then go to your local hardware store and get some cheap electrostatic filters like this: http://www.homedepot.com/p/True-Blue-12-in-x-4-in-Electrostatic-FPR-2-Vent-Filter-VF412-1/100351384#.UtlZxPQo5-E
Simply cut out squares and mount/tape them in front of all of your intake fans. They will catch the bulk of the particulates that come through your computer, and when they start getting dusty you can simply wash them in the sink and put them back into place. I did this for years before I finally got a case that had filters built in and it worked like a charm.
