Excessive Heating on CPU and Motherboard

[asf1992]

hello guys
My motherboard and my cpu is heating in a very odd way from the last 2 days
my idle cpu temp was 39 °C and on full load went to 42-43 °C max
but from last 2 days its idle temp is 42°C and if i give it a little load (like extracting a file) it hits 60
even the motherboard sensors show overheating
my system temp was always 37-40°C now it shows 45-47°C

also i have noticed some kind of errosion/corrosion on the sides of the cpu (is it sign of inadequate cooling)

Cpu : AMD Phenom II x 955BE @3.2GHz (no overclocking) with the packaged fan
Ram : Transcend 4GB @1333Mhz
MB : Gigabyte GA880GM-USB3 Rev 3.1
HD : Seagate 7200RPM 160GB + 500Gb
PSU : iBall 230W (will be upgrading to Cool Master extreme power 500W)

make sure the cpu fan is moving...it could be dust bound or a wire jammed in the fan. if nto see that the cpu heat sink is seated and that the cpu fan is spinning up to speed.

I just separated the CPU fan and the Heatsink and removed lots of dust accumulated in the heatsink
now the cpu is working fine
but what about "temp 3" displayed in "speed-fan" ??? it is almost 56°C
but after cleaning its reduced by 2-3°C its still fluctuating

depends where the sensor is and how the airflow in your case...if it one by the cpu and is reading the cpu slot temps...try opening the side panel and see if more airflow makes the temps go down..most good cases have a push/pull system..one fan pulling air into the case and one fan blowing the hot air out.

the side panel is always open
