CPU ( AMD ATHLON II X2 220) - 29-30 degrees idle
AMD 785G Motherboard- 35-37 degrees idle
GPU ATI HD 4670 - 44 degrees idle
Now the reason I am asking is that perhaps a month ago the computer was running at 15 degrees cpu idle, and 20-25 degrees Motherboard idle. Seems to have changed quite a bit, I can see a bit of dust on the cpu but how would I clean the motherboard to reduce temperatures? The Graphics card temperature seems normal for me as its a HIS HD 4670 isilence 4, meaning its passively cooled ( 0 db) with just heatsinks. Also could someone link me to how to take off a cpu heatsink with fan so I can clean it?

Use a can of compressed air to blow the dust out of the CPU heat and other ares in your PC.
Here is a procedure on how to reduce heat inside your PC.
When you PC is open, make sure that all of the fans are spinning. Also, don't enclose your PC in a tight air space such as a desk.
See how the above suggestions work before considering the removal of the CPU heat sink.
Try some different software for CPU temperature monitoring in case the application that you are using is faulty. This is a fairly common problem.

Hi thanks for replying, is it possible to use a hair dryer along with a brush instead of a compressed air can? Also how can I take off the CPU fan and heatsink to clean it off and I also have some Arctic MX-2 (thermal Paste)

Hair dryers don't have a concentrated (focused) air stream that will penetrate far enough into the heat sink.
Does the sink sink feel loose by chance?
You will have to unclasp the fan (there should be a clamp on each side) to get at the four heat sink removal screws. Once the heat sink is removed, then use some isopropyl alcohol to clean off the old thermal paste from the bottom of the heat sink and the top of the processor. You only need to apply a small amount (no bigger than a pea) of thermal paste to the top of the processor. You can even out the thermal paste with a straight single edge razor blade but it doesn't make much difference as the tightening of the heat sink on top of the processor will spread out the paste.
Arctic MX-2 is an excellent thermal paste. I typically use Arctic Sliver 5 which is on par with MX-2.
BTW, clean the heat sink with compressed air after you remove it but before you apply the new thermal paste.
