About a year ago, I went to a computer shop for my first gaming desktop PC. I picked the parts I wanted and asked the specialist to build it.
I had no idea why I chose those particular parts apart from balancing between my budget and performance I can get within the budget limit.

Some of the informations might be incomplete, but as I'm not a technical person, this is as far as I can extract :

CPU: Intel Core i5-2500K 3.3GHz Quad-Core Processor (not OCed)
CPU Cooler: Stock cooler that comes together with the CPU
Motherboard: Asus P8Z68-V Pro/Gen3 Motherboard
Memory: Cosair Vengeance 8GB (2 x 4GB) DDR3-1600 Memory
Storage: Hitachi 500GB 3.5" Internal Hard Drive
Storage: Intel 520 Series 180GB 2.5" Solid State Disk
Video Card: EVGA GeForce GTX 570 4GB Video Card
Case: CM Elite 311 Plus
Power Supply: Cooler Master eXtreme Power Plus 550W
Optical Drive: Samsung 24X DVD writer SH-S243D

I use this PC mostly for gaming ( BF3, BO2, Dota2, SC2, Skyrim ). Other than that, I use it for surfing & watching movies.

I have no problem with this system until recently I noticed that the system is literally crying out loud when I was playing skyrim.
Then, I checked the heat generation from the system and it's pretty hot too. Most of the noise seems to be from the power supply that I think.

So I tried cleaning (airblow) inside the system, but the noise and heat generation doesn't improve. ( cable management is not very bad by the way)

Therefore, I would like to ask the community how to solve this noise/heat issue.

Should I upgrade or just build a new system.

If I had to upgrade, which parts should be changed for a budget below US$700?
If I had to build a new system, what would be the best configuration under budget US$1500?

I am from singapore. This is my 2nd post in this forum, so please kindly forgive if there's any mistake or offence that I untentionally made.

Thank you for your help.
