I have a i5 2500k for about 3-4 months. Now i have the stock cooler on it and it is not overclocked.
When i built the machine the max temps i was getting from the cpu was 54c at full load for 5 hours using prime 95 but the past week i noticed the temps where rising, when i am playing games it hits 63c (bf3)
I prime 95 it again and the temp go to 71c after 3 minutes and then i stopped the test in fear of frying the cpu.
I checked the heatsink and it is firmly in place and all 4 pins are locked down properly and i cannot understand why the temps have suddenly changed.
I have the fan on 100% and nothing has changed in the system or temp in the room the pc is in.
Can anyone shed any light
btw i know the stock cooler isnt great but because of the memory i have it is hard to find an aftermarket cooler that will fit but the stock fan and heatsink was doing the job just fine till this last week.

I take it you aren't aware of any major changes in those 3-4 months? Has dust built up or have you changed any of the fan settings in BIOS?
Have your PC clean, it's been 3 months and dust has accumulated there. A CoolerMaster V6 fits right even on standard ddr3 mems.
